|Re: The Audi And Volkswagen Issues Resolution Thread by lordimpaq(m): 4:53pm On Nov 24, 2011|
nice one, very nice,
good job by the way, do you by any chance know where one can get an Audi repair manual or service manual?
|Re: The Audi And Volkswagen Issues Resolution Thread by iKoksi(m): 5:24pm On Nov 24, 2011|
This thread is now first step to get my machine sorted out, God bless Sir.
1) A4 Quattro
2) 3.0L V6
3) Trans: Auto
6) Drive Config: P. AWD
50) A/C blows hot air: on driving the car from Lagos to Abuja, I noticed d a/c will blow abit cold while stand still or driving slowly, but at high speed only hot air from vents. @ d moment no longer cold at all. Had d refrigerant flushed and recharged but didn't help. Also bits missing on d A/C unit display.
14) Check Engine illuminated (and almost all other warning signs!)
25) Occationally while on 'D' the PRNDS all illuminates at the same time
06) The car will start and run normally but Occationally jerks in motion, fuel consumption seems high.
The car is a week old, millage @ 20,000. I'll do everything to it back to best performance 'cos I love d machine.
How much will a compatible diagnostic equipment cost, do you have a link to download maintenance manual please?
Many thanks in Anticipation Sir.

Beautiful thread and great format . . . keep up the great work
|Re: The Audi And Volkswagen Issues Resolution Thread by Siena(m): 6:34pm On Nov 24, 2011|
IKoksi, thanks for submitting your query.
3,0L V6 2 x DOHC 30V, 220 bhp, 300Nm. 2001 - 2005.
Your issues would be as follows:
50) Aircon blows hot air. Possible cause:
A) Faulty pressure switch. This switch is located on the condenser, at the front of the car. It's fairly tight to get to - below the drivers side headlamp. Function? It allows the control panel / unit (this is the digital display below the audio) to determine how much gas (R123-A) is in the system. Running the system dry would damage the compressor. So if the pressure drops too low for safety, it will go open circuit. This will cut off power to the compressor. The B6 A4 has no clutch, it's the later variable displacement type, so failure is very rare. I've never had to replace one, though I've found cause to replace faulty pressure switches. This is relatively inexpensive, and will be the first port of call.
B) Faulty control panel. The control panel combines the ECU (Electronic Control Unit). Missing digits / pixels on the display can be attributed to an internal fault with the panel. Not cheap to buy new, relatively inexpensive used. The pressure switch fault can also trigger odd displays too. The Climate Control is fully OBD compliant, so a scan would be your first step. But I'm willing to bet your pressure switch is the culprit.
14/06) Check engine light illuminated. Again, a scan is in order. As you say it jerks intermittently and fuel consumption is higher than normal, I am combining 14 and 06. A scam will likely show:
A) Random misfire detected, cylinder ***
B) Multiple misfire detected, cylinder ***
C) Engine speed signal, implausible signal.
D) Oxygen sensor, bank 2.
Most misfire issues are to do with the coilpacks. Your 3,0 V6 30V has individual coil packs, so six. A scan will identify which cylinder/s is/are affected.
You also mention all other warning lights. Could you please confirm:
a) Check engine light - illuminated.
b) EPC (Electronic Performance Control) light - illuminated.
c) CAT (Catalytic Converter) light - illuminated.
d) Key light (immobiliser) light - flashing.
25) PRNDS all illuminate intermittently whilst in "". This is the most serious issue. Your can runs the ZF5HP19a 5-speed tiptronic, with Sport mode. The fluid must be replaced, along with the filter every 30,000 miles. This involves dropping the oil pan, and flushing the system through. It holds about 9 litres, though you'll only ever get about 5,5 - 6 litres out, as it's impossible to drain the torque converter with the transmission in situ.
Again, scan the car. If the PRNDS illuminates, it means the transmission is in limp mode. In this mode, generally only one forward gear is available - third. The car will be sluggish from low speeds, as the lower gears are no longer used. It also won't shift into 4th or 5th. Switching off the car and restarting will usually clear it, but only temporarily. The engine ECU also "talks" to the transmission TCU, and if transmission is in limp mode, the ECU will limit engine output to prevent damage. The engine will be thirstier than normal. A transmission fault can also trigger a check engine / EPC light.
It's also worth noting the TCU lives under the front floor covering, so any water / moisture there will kill it. A dead TCU is better than an internal transmission fault, as this means a complete strip down and rebuild. Or a replacement.
Please scan the following:
c) Climate control.
Post whatever codes you come up with, and I'll talk you through the processes you'll need to take for rectification.

dont know engine size
manual, 4 speed
my moms audi 80 do jerk at speed 70km/h and above then stops even on the highway and most times the cadburretor wont supply fuel, so u will have to add little fuel to the cadburretor. i took it to the mechanic after servicing the cadburretor myself and the mechanic said there's no problem with the cadburretor, that it should be the fuel pump.the car is still very clean but it can no longer go a straight 1km without it jerking and stopping, and this whole mess started lately. what do i do?
secondly: the car wont start, and when it starts, it wont off. I tried fixin that myself too, and it worked but at times it wont even start at all. so what do u think is the problem?
|Re: The Audi And Volkswagen Issues Resolution Thread by Siena(m): 12:01am On Nov 25, 2011|
Tiniyata: I'll look into your queries with regards the Audi 80. Won't be easy though, as I have little to go on - no model year or engine size. So I have no idea which fuel system it has. You've mentioned carburettor though, so I'll assume it's a 1,6 / 1,8S. 2,0 models were all fuel injected, though the base model had single-point injection, which some mechanics junked in favour of a basic carburettor[i].[/i]..
I'll get back to you on this.

Baba Siena nice thread , keep it Up
|Re: The Audi And Volkswagen Issues Resolution Thread by junglej: 10:19am On Nov 25, 2011|
dude, keep up the good work. Please i don't know where to start, but this car has been giving me series of problems since i brought it to Abuja from Lag. Changed the gearbox, but mechanic says the engine is not strong enough to carry the AC, done lots of repairs (what i call trial and error) because i have spent way too much.
The present problem is now the start. I initially though it was the battery cos it refuses to start, but i tried using other batteries and it still will not start, its not the alternator because i asked an electrician to help me check, the kick starter is new, someone told me its a kick in the engine. Please if you are in Abuja or know someone in Abuja that is good with Audi's of this model, please be of assistance.
|Re: The Audi And Volkswagen Issues Resolution Thread by Siena(m): 10:52am On Nov 25, 2011|
For starters, when you say your Audi 80 fails to start, there are three things to contend with here:
a) The engine cranks (turns over) but won't start.
b) The engine makes no noise at all when you turn the ignition key.
c) The starter motor spins, but does NOT turn the engine.
As for Nigerian mechanics saying an engine is not strong enough to operate the aircon compressor, that's wrong. Generally, and engine that's had the crankshaft reground will have undersize bearings to match. Of course a regrind means, in laymans terms the crank journals were damaged. So a regrind removes some metal to make it smooth again. This makes the journals marginally thinner, and of course weaker. But, it does not mean the engine won't operate the compressor. The stresses of an aircon compressor pumping gas is way less than the loads placed upon the engine simply by driving, or even turning the steering wheel full lock (the power steering pump loads up the engine, more than aircon). A car with a 1,0L 45 bhp engine will still have aircon.
Please give me the information I've requested in a) b) and c) and we'll take things from there.

pls siena, i want to start a disgnostic biz for all german made cars/suv/sav/light trucks from 98 upwards, using OBDII interface or above.
Would you please advice on the best diagnostic kit to use. Can you pls reply to my mailbox. email@example.com
|Re: The Audi And Volkswagen Issues Resolution Thread by Siena(m): 12:25pm On Nov 25, 2011|
Hi! The Audi A4 B5 ran from September 1994 - March 2001. The 2,8 V6 engine came in different guises, depending on the model year, split between 12V and 30V. I need a model year. Giving between '96 - '00 is way too broad a spectrum to use in deciding if it's a good buy or not. Later models also had Sport mode in the automatic optioned cars.
Is it FWD or quattro?

good one siena,always ready to help
|Re: The Audi And Volkswagen Issues Resolution Thread by Siena(m): 1:31pm On Nov 25, 2011|
Two possible causes. I would rule out your battery, because the first thing you'd have done was either get a jump start, or try other batteries, which you have done. You've also confirmed the starter motor is new.
a) Starter inhibitor switch. This is the switch that prevents the engine from being started unless the gear shift is in P or N. These rarely go faulty, the most common issue is incorrect adjustment. If the gear shift is not absolutely aligned, the switch will register the shift as being in either R or D, and will prevent starting. Try starting the car, whilst moving the gear shift gently back and forth. If it starts, you've found your problem.
b) Faulty ignition switch. The most common fault of the Audi 80/90 B4 and early Audi A4 B5. The switch is housed within the ignition lock, there is a plastic assembly, with a slot in the middle. A metal peg from the ignition lock fits into this slot. Over time, the plastic assembly in the switch becomes brittle, and cracks. This means when the key is turned, the metal peg rotates within the plastic assembly in the switch, but fails to turn it fully. It will turn the switch to the "ignition on" position, but not to the "start" position. The "start" position is spring loaded, so the metal peg will simply slip, rather than overcome the spring resistance.
From experience, I would say your problem lies in the ignition switch. Get another one, and replace. It's easy to replace, it's held in the ignition lock assembly by two screws. You can actually pull the plug off the back, plug it to a new one, and use a screwdriver to turn the plastic assembly. This is just for test purpose only, as to drive like this, you'll still need the key to unlock the steering.
Just to give you an idea, I'm attaching some images below. The top picture shows two switches side by side - the cracked one is clearly the one on the right. The middle picture shows the Audi 80 ignition switch. Then finally, the ignition lock housing, that the switch fits into, is the last picture. The switch fits within the housing, in the direction of the arrow:

My Broda man, a great day to you. l just newly acquired a Volkswagen Vento 1994 CL model from Cotonou, Benin Republic. lts an automatic transmission drive. l discovered the Owners manual as well as its service manual are both written out in German. l'll appreciate if you could oblige me with information on where to procure an English version of the above manuals or in the alternative sites where l could download same. Secondly, l'm having issues with the car horn, hazard lights and trafficators lights dwhich do not work when you switch them on and also the rear parking lights are permanently on, thus forcing me to take the bulps out of the sockets so as not to drain the battery. could the problem be fuse related? l'm scared of taking the car to road side electrician. This is my first ride.Your views would be highly appreciated. Cheers.
|Re: The Audi And Volkswagen Issues Resolution Thread by gogodaye(m): 2:08pm On Nov 25, 2011|
In addition, l'll equally appreciate being provided with a step by step guide on how to input the code to unlock the cars' gamma radio set which only indicates 'SAFE' when switched on. Thank you and Cheers.
|Re: The Audi And Volkswagen Issues Resolution Thread by kl2020: 2:42pm On Nov 25, 2011|
come 2 nigeria and open a mechanic workshop, it will help a lot
|Re: The Audi And Volkswagen Issues Resolution Thread by Siena(m): 2:52pm On Nov 25, 2011|
I'll try obtaining a copy of the Volkswagen Vento Owner's Manual in English.
The issues with your horn, hazard and indicators, would suggest a fault within the steering column / combination switch. I believe your hazard switch is on top of the steering column. And your tail lamps are stuck "on." Possible scenarios:
a) Faulty combination switch.
b) Missing earth connection.
Could you also confirm if the wipers and heater blower (interior fan) work?
If the switch is missing an earth, the horn definitely won't work. Unlike the rest of the car's electrical systems that have a permanent earth, and require a switched live (+12V) to activate them, the horn is the reverse. So the horn has +12V permanent supply, as long as the ignition is switched on. The horn contact switch in the middle of the steering wheel is an earth (-12V) trigger. No earth - no horn. The hazard lamps also need the same earth to work. If the central hazard switch is open circuit, the individual indicators won't work either.
Your rear lamps stuck on - are you sure it's not the brake lights? usually if your tail lamps are on, your front sidelamps will be on too. The brake lamps on Volkswagen and Audi have a permanent +12V feed to the switch, so don't rely on the ignition being one to work.
Please confirm the brake lamps still work, and we'll take things from there.
