Question about 1996 Audi A4

1 Answer

Update on my problem to audi a4 1.8 1996

I posted a comment about white smoke on replaceing my maf now that has gone.

I swaped my maf back to old one no white smoke, my car still seem to die throught.

The car will not start with out my putting my foot on the power then it goes from 300rpm to 1000rpm then bk down to 300rmp then it either decided it want to cut out (need to restart with power) Or it then leavel off at 1000rpm.

I also if i rev it to 4000rpm then let it go bk down it will just cut out or go to like 100rpm light comes on then it manages to save it self.

Can anyone help me? also i heard it could be idle control sensor can anyone tell me where that is located.

Regards

Chris Johnson

The MAF has been a source of trouble for Audi such that the cost of replacement was halved a few years ago.

I am not sure why replacing the MAF would produce white smoke - white smoke being symptomatic of steam from water or coolant ingress into the cylinders or extreme amounts of fuel entering the cylinders. The latter is almost exclusively a diesel problem.

Generally if the MAF is suspected of being the cause of rough running then disconnecting it will cause the engine management to switch to the get-you-home programme. If the engine runs better the MAF is probably faulty..

As a matter of interest, it is necessary when changing parts on Audi that only the correct parts are used. Not only must they look right and be intended for that year and model but the part numbers should also be correct. A couple of digits out isn't close enough...

I am not sure where the idle thingy is on your Audi - the earlier models used a throttle body with the idle/throttle sensor and idle control all integrated in one very expensive lump and that is how I discovered the importance of correct part numbers.
In order to save my customer from scrapping what was otherwise a good car, I took a can-opener to the throttle body and opened it and found two broken wires and mananged to repair them. I needed to do some tricky welding to put it back together. The car went on for another seven years afterwards...

The car made no white smoke prior to the repair but the idle was very erratic...

what does the white smoke smell like-does it smell sweet-my bet is anti freeze-its just not run long enough to consume very much-this would mean a leaking head gasket-Denny

Black smoke and 'juddering' when stationary.


YOU HAVE RICH MIXTURE. CHECK FOR YOUR TEMPERATURE SENSOR WHICH I BELIEVE IS NOT SENDING THE CORRECT MESSAGE TOY PCM AND STILL WORKING ON COLD START.

Suzuki Vitara V6, MAF sensor, white smoke.


Hi:
My first thoughts are that you have a head gasket or intake manifold gasket failure. This is why you have the white smoke. If you run it too long, your catalytic converter will be destroyed. Check for coolant in your oil too.

AUDI A4.24 SLIGHT VEHICLE VIBRATION


If your engine is not misfiring but it vibrates too much while idling your motor mounts might be getting worn out. I had a Nissan with bad motor mounts. I was ok in park but when you put it in gear it vibrated a lot. It smoothed right out as soon as you started moving.

Large amount of white smoke from exhaust and loss of water from the system. No visible leaks.


ok open your oil cap and see if its creamy inside there
if it is there is water getting into the head
caused by blown head gasket
if not just get back to me and ill find the other soulution
