Audi 80 tdi - juddering problem

**Ed Ray** · 04-03-2007,05:28 PM

Right... i've been offered an Audi 80 tdi estate 1994. The car is in immaculate condition and is a good price - so im really keen on purchasing the car, but with no mechanical skills i need some reasurrance before purchasing.

The car has a juddering problem at around 1500 - 2000 rpm in 3rd, 4th, 5th - the car will judder and especially the gear stick. When get over 2000 rpm the problem goes.

Any advice, any ideas on what the problem might be?

Cheers

Ed

Hi Midskev. Sounds like we have the same problem.Did you ever get to the bottom of it? I read a post somewhere, though I can't find it now, that said disconnect the speedo. I did, and the problem almost went away. Almost, it's still there but not nearly as bad. It's still under powered and very slow on the hills. Has anybody discovered the remedy for what seems like a common problem?

It's still under powered and very slow on the hills.I have cleaned the inlet manifold and changed the MAF sensor so far but no joy. Has anybody discovered the remedy for what seems like a common problem?

Hi, All. I am having exactly the same simtums {judder @ 2000 rpm.] and it NOT the CLUTCH. I feel it must be eighter electronics or fuel related ?? It seems to be a very common problem judging by the number of members bringing this matter up !!!. So come on all U Audi / VW Tech's , Please put us poor suffers out of our pain!!!!!! Oh and U could save lives [as it's bloody dangerous.

Hello

@ Ed Ray
If you really like the car just buy it but with about 800 euro less cause that's how much you will spend to fix it. I've been looking for an answer to this problem for two yeas, the problem is the injection pump, change it or have it repaired. A normal test of the pump will say that the pump is ok but in fact the problem is the electronic part of the injection pump. I had my audi repaired this way, it runs perfect now.

All the best

I agree with fludor , I too think it's the fuel pump, but I think it's not a big problem,I will still drive it without fixing it , because it will cost too much for me.Mine is 1994 TDI 1Z , it still runs good ,top speed 180 km/h.
