You may guard its "bottom plate" so that it won't break.

Nice write up.

I commend the government for seeking people's opinions. Unfortunately, many of the people that are adversely affected by the lock down have no smartphone nor data subscription.

Plugging USB use to refresh browser/app. Android 10 update fixed it. Finger print sensor is now less responsive though.

Likely a faulty transmission still. Anything is possible, you need good diagnosis to isolate electrical problems (ecu, wiring resistance, solenoids, sensors).

Good responses.
Great cars with advanced engineering. I must say that many mechanics don't understand the system of these cars.
Quality of fuel available in Nigeria is a disaster for these cars and pain for the users.
Using octane booster won't cost more as it causes the engine to burn less fuel.

Durable but reliability is low.

Nice and informative writeup.

The ABS actuator (ABS pump) is likely faulty.

Hi, I have a 2006 Toyota Highlander Hybrid.
The 12v battery was changed recently and I noticed the "check vsc system" error code.

Now, it displays both "check hybrid system" and "check vsc system" error codes. It won't show ready when I start until I disconnect and reconnect the negative battery terminal.

I had someone scan it for me and I got the following codes.

Falsehood. Utter falsehood. Just market your business...

Go through my posts. I am not into childish arguments as you are used to. All you see me do on this platform is contribute what I know. I wasn't talking to you anyway. You don't know me and I don't know you. What is your problem with my business? I do guess that you don't even know anything about the system that I was referring to, and hence your rant and rude manners.
This level of immaturity is nauseating.
I am a very peaceful person and I don't like problems with people but congratulations as you go down in history as the one bad enough to make it happen. I will leave the rest of the argument for you to do with yourself as I won't give you the attention that you are looking for.

Is he using a scan tool to troubleshoot? You may need a technician that is good in fault diagnosis and has required tools.

For VW/Audi with direct fuel injection, troubleshooting is beyond an average DIY person or mechanic.

EnterpriseMan:
Yea, exertly.. it happens in the mornings and after about 10secs, it stablises.. So if it's the fuel pressure issue, how do I fix it?

Happened mostly in the morning right?
Wrong octane fuel or fuel pressure issue.

EnterpriseMan:
Model: Audi A4 2010 quattro premium
Transmission: Dual 6 speed automatic/manual
Engine: Turbo v4

whenever I start the car, i notice a slight vibration which later dies down. someone told me that maybe some of the engine seats are weak and need replacement, but I have to be sure.. it's a very beautiful car and works perfectly, and damn very fast. got it to hit 201km/h from Abuja to Benin. I just need to know what causes the vibration.

Thanks in advance

Have you checked water pump impeller, blocked exhaust, fuel trimv(for excessive lean running), spark plugs heat range?

Sheriff19:
Please, my VW golf 3 is overhearing and i have changed everything possible that has to do with the cooling system ( radiator, fan, thermostat e.t.c) every thing that has to do with the cooling system but the engine keep overheating. Please what is the solution.

I wish you can abort this mission.

OdogwuMike:
Thank Goodness I saw this thread. I have ordered a VW Passat 2007 FSI Manual transmission from the UK.

The issue is that the gear sterling is located at the right hand side and I would want to convert it to the left hand side once it arrives Lagos on the 28th of February.

Has anyone done this before? Who can recommend, based on experience, an expert who can do this perfectly without issue.

This is my WhatsApp no 08061106773, would love to be added in the group chat too.

It's possible that it is a fuel delivery issue,especially with the high pressure fuel pump in the engine bay.

Phedam:
Hello guys,
I use a 2007 model VW jetta.
I just noticed some days back that while accelerating, my car suddenly jerks violently.
Let me explain better, If the car is at, say 40km/hr and I start accelerating,
when it gets to like 60 it stops increasing speed and starts jerking violently,
if I take my leg a bit away from the pedal and move at constant speed (60km/hr) for about 30 seconds
and then accelerate again it will respond to the acceleration until I get to like 80km/hr and it jerks again.
and the same cycle occurs at 100km/hr.

Please is there anybody with an idea of what can be going wrong with the car.
Responses will be appreciated.
Thanks

The correct thing about toe in and toe out is opposite of what you have in the diagram.

Many things could cause this. Let me mention few.

Blocked exhaust Catalytic converter
Faulty Throttle position sensor
Weak fuel pump
Wrong timing/ Camshaft sensor or circuit /VVTI circuit or sensor
Fuse

In point 1. I guess you wanted to write "high fuel consumption *

Exactly!

AutoMoTech:
All depending on the design and what the engineers wanted to achieve. One size never fits all.

Nice writeup.
But from deeper research, it all depends on the car and the extent to which fuel economy is affected.
It also depends on where fuel economy is affected. At low end or high end. Check how the cat affects low end torque and scavenging.
Again, some cars use after cat sensors for fuel adjustment. It depends on the extent to which it does that. Some up to 10%, some 30%.
Regards.

Those that say so, maybe in their conventional cars, especially the ones with two batteries, the batteries pollute the environment than the internal combustion engine. That's not a reasonable thought.

The key thing is proper battery disposal/recycle after end of life.

I am looking forward to a time that I will see Nigerians discuss, contribute rather than argue. At least, contribute with few meaningful arguments.

It is an interesting question.
Personally, I like both torque and speed.
On most Nigerian roads, torque wins.
Most torquey cars are relatively low revving contributing to better fuel economy and engine longevity.
Some cars especially that of the Germans are versatile. They are ordinarily high speed cars but employ some other technogies like variable air intake, and so on to improve low to mid-range torque.
So even with same engine capacity, they win others in low and high speed race.
Let's remember other variables like impact of front and rear wheel on torque delivery and balance. Just so much to talk about.

OK.

HeavenlyBang:
Just telling you what I noticed after removing my cat.

Arguable.

HeavenlyBang:
AFAIK, cat deletes improve fuel economy, not the other way around.

You would have been correct if you said "high end power".
It actually reduces low end torque.
Regards.

HeavenlyBang:
Correct me if I'm wrong. You get a slightly better exhaust note and more low-end power with a cat delete. What are the perks of keeping your cat, emissions aside?

The width of your tire will remain the same. G
Height of tire will increase.
Ground clearance will increase a little. Road Handling will be poorer, Fuel consumption will increase, you will feel like acceleration has reduced.
Regards.

They make simple car, hence the reliability.
You are correct anyway.

foolbuster:
Lolz. Hands down they beat the Germans in making reliable cars.

Chai.. Will these people ever catch up with the Germans? A 2007 Honda o.

autologic:
Honda doesnt provide such pids ,beside the type of fuel pump design is not duty cycle type but pure direct 12v actuated by PCM via relay
Diagnosis this type of issue will require scoping the current waveform of the fuel pump amperage draw for volume test and performing pressure test with appropriate pressure transducer, analysis of this test and amperage waveform will tell such precise story ,however this is beyond DIY but advance diagnosis .
