Serious buyers only,delivery within Lagos and Ogun state ,call 08038940607

Please do you have the black colored variant?

decatalyst:


Yes, I changed the battery. The previous battery just suddenly started draining. I have change the alternator after battery change. Still issue persist. No corrosion on the battery head either.

Obviously the car will have to get to Lagos...as the guys in Ibadan no really sabi.

Please don't just generalize 'guys in Ibadan', I own BMW cars and am in Ibadan, I have never had cos to take any repair to Lagos b4 I get solutions.
Wish I know the 'guys' you have patronized or at least the areas their workshops are located.

autologic:

U need to confirm if maybe u have one of the injectors that is stuck open a little or fuel pump that is supplying above the stock psi ,or faulty ecu that it's mapping for injection control is corrupt .

Fuel Trim
by Larry Carley copyright 2019 AA1Car.com

Fuel Trim is the adjustment the engine computer (PCM) makes to the fuel mixture to maintain a balanced air/fuel ratio. Fuel trim is usually displayed as a PERCENTAGE reading on a scan tool.
For lowest emissions, the engine computer tries to keep the fuel mixture balanced around 14.7 to 1 (14.7 parts of air to one part fuel). If the air/fuel ratio is less than 14.7 to one (say 12 to 1), the fuel mixture is RICH. A rich fuel mixture can produce more power (up to a point) but it also increases fuel consumption and emissions. Conversely, if the fuel mixture is greater than 14.7 to one (say 16 to one), it is LEAN. A lean fuel mixture reduces fuel consumption but can also increase emissions if the air/fuel mixture is so lean that it fails to ignite and causes lean misfire.



The engine computer monitors the air/fuel ratio via the oxygen sensor(s) in the exhaust manifold(s). An oxygen sensor is essentially a RICH or LEAN indicator. When the engine is running lean (too much air and not enough fuel), the O2 sensor generates a low voltage signal that tells the engine computer more fuel is needed. When the engine is running rich (too much fuel and not enough air), the O2 sensor produces a higher voltage signal that tells the engine computer the engine is getting too much fuel and to cut back the fuel delivery. On vehicles that have an Wide Ratio Air/Fuel sensor (WRAF) or A/F sensor, the sensor tells the computer the exact air fuel sensor so the computer can increase or decrease the fuel delivery as needed.

Accurate fuel trim values require an accurate feedback signal from the Oxygen sensor, otherwise the engine computer has no way of knowing whether the fuel mixture is running rich or lean.

When a cold engine is first started, it may take 10 to 30 seconds or more for the heaters inside the oxygen sensors to warms the sensors up to operating temperature. Until that point is reached and the fuel feedback control system goes into "closed loop", the fuel mixture is fixed at a predetermined value so no fuel trim adjustments are made. But once the Oxygen sensors are hot and the coolant temperature is high enough for the computer to go into closed loop, the computer starts to generate fuel trim values and make adjustments in the fuel mixture.

When the engine is shut off, the fuel trim values are retained in the computer's memory so the next time the vehicle is driven it can pick up where it left off. Erasing the computer's memory with a scan tool or by disconnecting the battery or the PCM power supply to clear codes also wipes the fuel trim values, which means the computer has to start learning the fuel adjustments all over again the next time the engine runs.




How to Read Fuel Trim
The fuel trim value is read by plugging a scan tool into the OBD II diagnostic connector located under the instrument panel (on the drivers side near the steering column). When the key is turned on, the scan tool will initialize and start to communicate with the vehicle's onboard computer. Depending on the tool and the vehicle, it may be necessary to enter the vehicle year, make, model and engine VIN code before the scan tool can read the data.

The engine must be started and running to read the fuel trim information. Depending on the scan tool and how its menu options are set up, you choose the option that allows you to read system live data. This will display a long list of sensor outputs and other readings called PIDs (Parameter IDs). On this list will be two fuel trim values for inline four and six cylinder engines, and four fuel trim values for V6 and V8 engines (one pair for each cylinder bank).

There are two types of fuel trim values shown:

Short Term Fuel Trim (STFT) is what the engine computer is doing to the fuel mixture right now.

This value changes rapidly and can bounce around quite a bit depending on engine load, speed, temperature and other operating conditions).
Values normally range from negative 10 percent to positive 10 percent, though the readings may jump as much as 25 percent or more in either direction.

Long Term Fuel Trim (LTFT) is a longer term average of what the engine computer has been doing to balance the fuel mixture over a predetermined interval of time.
This value is a more accurate indicator of how the fuel mixture is being corrected to compensate for changes in the air/fuel ratio that are occurring inside the engine.

STFT B1 is Short Term Fuel Trim engine cylinder Bank 1
STFT B2 is Short Term Fuel Trim engine cylinder Bank 2
LTFT B1 is Long Term Fuel Trim engine cylinder Bank 1
LTFT B2 is Long Term Fuel Trim engine cylinder Bank 2

How do you know which cylinder bank is 1 or 2 on a V6 or V8 engine? Bank 1 will be the cylinder bank that has cylinder number one in the engine firing order. For more information on firing orders, see the following:

Firing Orders (Chevy)

Firing Orders (Chrysler)

Firing Orders (Ford)




What Fuel Trim Values Mean
POSITIVE fuel trim values mean the engine computer is adding fuel (increasing the pulse width or on-time of the fuel injectors) to add more fuel to the engine. In other words, it is attempting to RICHEN the fuel mixture because it thinks the engine's air/fuel mixture is running too lean.

NEGATIVE (-) fuel trim values mean the engine computer is subtracting fuel (decreasing the pulse width or on-time of the fuel injectors) to reduce the amount of fuel injected into the engine. This is done to LEAN out the fuel mixture to compensate for what it perceives as a rich running condition.

Remember, all this is based on what the oxygen sensors are telling the engine computer. If the O2 sensors indicate LEAN, the computer adds fuel and generates a POSITIVE fuel trim value. If the O2 sensors are reading RICH, the computer compensates by subtracting fuel and generates a NEGATIVE fuel trim value.

By reading the STFT and LTFT fuel trim values on a scan tool while your engine is running, you can tell if the air/fuel mixture is running rich (negative fuel trim percentages) or lean (positive fuel trim percentages).

What Fuel Trim Values Should Be
Ideally, the STFT and LTFT should be within a few percentage points of zero when the engine is idling or being held at a steady RPM. Remember, STFT can bounce around quite a bit as when you suddenly snap open the throttle or decelerate. But LTFT can tell you if the average fuel/mixture is running rich or lean.

Good LTFT values should be as close to zero as possible, though they can range from 5 to 8 percent depending on the condition of the engine. If the LTFT is getting up around 10 percent or higher, it usually indicates a problem that needs to be diagnosed.



LTFT values that get up around 20 to 25 percent will usually set a P0171 or P0174 lean code.

LTFT values that drop down to negative 20 to 25 will usually set a P0172 or P0175 rich code.

scantool fuel trim closeup
This scantool is displaying a STFT value of 25 percent. Normally that would indicate a problem,
but in this case the engine is not running (Engine RPM is zero). As soon as the engine starts
and goes into closed loop, the fuel trim readings will begin to change.

How Fuel, Ignition and Engine Problems Affect Fuel Trim
Lean fuel mixtures are a more common problem than rich fuel mixtures, though either can happen depending on the cause.
LEAN fuel mixtures will generate higher than normal POSITIVE fuel trim readings on your scan tool.
RICH fuel mixtures will generate NEGATIVE fuel trim values.

Possible causes of LEAN fuel mixtures include:
Air or vacuum leaks in the intake manifold, near the throttle body or at vacuum hose connections.

Weak fuel pump that is not generating enough pressure or volume



Fuel line restrictions (like a pinches hose or plugged filter)

A weak fuel pressure regulator that is not maintaining adequate fuel pressure

Air leaks in the PCV plumbing

Dirty MAF (Mass Airflow) sensor that is under reading airflow into the engine

Dirty or dead fuel injectors

Ignition misfire (a fouled spark plug, weak ignition coil or bad plug wire that causes a misfire allows unburned oxygen to pass into the exhaust and fool the O2 sensors)

Compression leaks (bad exhaust valve that allows unburned oxygen into exhaust and fools O2 sensors)

Exhaust manifold crack or gasket leak (allows unburned air into exhaust and fools O2 sensors)

Bad O2 sensor (signal shorted to ground so the sensor reads lean all the time)

Possible causes of RICH fuel mixtures include:
Leaky fuel injector

Excessive fuel pressure due to bad fuel pressure regulator or restricted fuel return line

Extremely dirty air filter or restrictions in air intake system

Exhaust restrictions (clogged converter, crushed exhaust pipe or plugged muffler)

Bad O2 sensor (output shorted to voltage so it reads RICH all the time)


Using Fuel Trim to Diagnose Problems
Use Fuel Trim to Diagnose Vacuum and Fuel Delivery Leaks. With the engine idling, look at the Short Term Fuel Trim (STFT) and Long Term Fuel Trim (LTFT) values. Normal range may be high as plus or minus 8, but closer to zero is best. If the numbers are +10 or higher for STFT and LTFT, your engine is running LEAN. Rev the engine to 1500 to 2000 RPM and hold it steady for half a minute or so. If the fuel trim numbers drops back down to a more normal reading, it confirms the engine has a vacuum leak at idle. This is because vacuum leaks have less of a leaning effect on the fuel mixture as engine speed and load increase.

If the fuel trim readings do not change much, the lean fuel condition is more likely due to a fuel delivery problem (weak fuel pump, restricted fuel filter, dirty fuel injectors or a leaky fuel pressure regulator) than a vacuum leak.



LTFT fuel trim readings that are trending high might also be the result of a slight ignition misfire that is not bad enough yet to set a misfire code but is bad enough to cause a drop in fuel economy. One or more fouled spark plugs that are misfiring occasionally, or a weak ignition coil or bad plug wire that is allowing some occasional misfires could be the cause. For more information on misfire diagnose, Click Here.

You can use fuel trim to identify dirty fuel injectors. If the LTFT fuel trim readings are trending up (POSITIVE), it means the fuel feedback control system is compensating for an air/fuel mixture that is becoming progressively leaner over time. The most likely cause would be dirty fuel injectors. Fuel delivery can be restricted by the accumulation of varnish deposits inside the injector nozzles. The fix here is to clean the injectors. If the fuel trim values return to normal after the injectors have been cleaned, it verifies you have solved the problem. If the fuel trim values don't change after cleaning the injectors, the lean fuel condition may be due to low fuel pressure or air/vacuum leaks.

You can use fuel trim readings to check the response of the oxygen sensors and engine computer to changes you make in the fuel mixture. While the engine is idling, temporarily disconnect a vacuum hose. You should see the STFT fuel trim readings jump immediately and go POSITIVE, and the LTFT should start to creep up in response to the artificial lean fuel mixture you have just created by disconnecting the vacuum hose.

To test a rich response, you can feed some propane vapor from a small propane tank into the throttle body or a vacuum hose connection on the intake manifold. This time, you should see a drop in fuel trim readings, with STFT going NEGATIVE, and LTFT creeping downward in response to the rich fuel mixture.

No change in fuel trim readings when you create an artificial lean or rich fuel mixture would tell you the engine computer is NOT operating in closes loop, or that the oxygen sensor(s) are not responding to changes in the fuel mixture.

Hoping it helps someone.

A wise man once said 'All those that fought Goodluck Jonathan would never go unpunished, be they in PDP or others'

EgunMogaji2:
I got my truck as a Nigeria Used about 6 years ago. It has served me solidly with zero complaints.

I took it in specifically for two things.

1) Replace rear main seal as there's a leak and

2) Change both knock sensors.

During the work they said oil was also leaking from the cylinder head cover. So I gave the go ahead to change the cover gaskets and hence the start of the melee.

When they opened the cylinder head cover they encountered sludge, to me not a biggie if left alone but they went ahead and "cleaned it". Car started fine and I drove to Ijebu Ode. On the way back it developed rod knock at Oru. Drove it with the noise from there to Ibadan (Note: Police will give you a pass if you have car trouble so they have a heart after all).

I replaced it with a used engine and I'm back on the road.

Moral of the story. Try not to create sludge, mine came with the truck. If you're going to clean sludge then you have to remove the lower pans, oil pump, etc I didn't tell my Kazeem this because I assumed that he knew.

Egbon....welcome sir
Honestly there is this local oil brand that I have been using for sometime now without any issues.
Reasons I went for it was that:
1. I see a lot of heavy duty trucks use the brand I then opted for the ones specified for cars.
2. Brand is manufactured in Kano but easily available in Ibadan, searched for it sometime early last year in some part of Lagos and couldn't find it.

Lesson learnt today is to continue with my local brand(especially on aged engines) but frequent change intervals.

Pls what's the model of this santin

weyreypey:

Inspect and if okay buy....but I hate converted w203's even when unconverted they look somehow in the engine bay. Meanwhile the model is plagued by defective electricals...

Thanks for your input, I wish I have as much knowledge as I have on BMWs

weyreypey:

Why is he selling at a loss?

He contested in d primaries of the last elections, probably he needs to offset some debts incurred.
He even sold a 2005 Xc90 Volvo for 500k

HeavenlyBang:


IS250 and it's not even close.




2004 C300? Or C200?
If he spent 300k on conversion, why is he selling?

Imo, don't buy.

C200 pls

2004 C300 Kompressor Converted from RHD to LHD, the owner boasted of spending upto 300k for d conversion and yes d owner has such money.
Would it be OK for a 1st benz?
I own an 03 3 series BMW now so cost of maintenance won't be an issue.
Car not registered and he is asking for 800k.
My questions here is about d conversion pls.

This is my field and am resident in Ibadan, I am directly or indirectly connected to one of the networks carrying out this infra implementation at the moment in Ibadan so I have knowledge of what is going on at the moment. Expect more excavations in Ibadan metropolis in d next month as more contractors are about to commence work.
Now the problem of not reinstating d roads to their original condition IS NOT from the telecom companies that excavated the roads. Some years ago under the present administration in this state, the government decided that NO opco should carryout asphalt reinstatement by themselves claiming in professionalism. Since then when any opcos pay for Right of Way(permission to dig on the roads) the also pay the government to repair the roads themselves after they are done. Also note that there is a Supervising engineer from the state ministry that is paid by the contractor to monitor their excavation activities.
Long story short, every where you see a road not reinstated to its original condition after telecom digging, its the responsibility if d state.
On the bright side watch for one particular network that has d best 4G in Ibadan, they would be rolling out 5G once this implementation is completed and Ibadan would become a High Speed internet Hub.

U later paid the over 4k?
Received mine today at Ilorin post office and I paid only 400 naira only.

An insider helped reduce it to #3200 and i was issued an official receipt.

Mustack:

which phone is that

Santin N1 max

Lexusgs430:


Seller probably did not declare...... Adefemi007 and godric or krozay, also got hammered by custom duty......

Thanks for ur response.
Seller actually indicated $18 phone accessories but I found out that customs opened d package and verified what was in it B4 resealing, this was confirmed to me at d PO.

Help!
Ordered a phone on AE, asked seller to declear phone as $18 phone accessories now phone is at PO and am asked to pay #4200.
How do I confirm if seller decleared phone as $18 accessories?
Has anyone paid up to this for a phone less than $120?
