Hello,

I got 2000 2.8 L A6 Avant 220 000 km with Multitronic transmission (CVT).

CVT showed some problems that local Audi deler cannot fix (nor can explain). There is no transmission rebuild shop for CVT in our country.

Problem description: CVT still runs but in the range of engine rpm 1100-1800
produces periodic (2-3 s interval) metal rattling sound like metal slipping over metal. Engine revs
jump slightly (say from 1400 to 1500) during this sound and the vibration comes out of CVT. No codes during scan. CVT fluid was
replaced at 125.000 km. Less evident in cold (it runs almost smooth first few miles). Effect emerged 5-7.000 km ago and gradually develops.....

Questions:
- is it possible to rebuild this transmission somwhere?
- does anyone know what it is?
- can you help with contact in Audi AG for consultation?

Thanks

Dmitri

 

Sounds like your clutchs are sliping I think that the origanal clutchs were 5 plate and they have been replaced with 7 plate clutchs. The new 7 plate cluch fits right in place of the old 5 plate, if the clutches were burnt when you took the oil out there would have been resadue this is carried out by the Audi dealer. While your there you could ask them to check the measured value block for the valve body to see if you have any sticky valves, if so you would need a new valve body but it sounds more like the clutchs.

Hi looks like I have finally found some people that knows about the CVT transmission.
I have a 2002 A4 with the CVT. and I hope you guys might have some answers.
Do you know what is the best way of launching with a CVT... in manual mode or automatic?

How does the car decide how fst to engage the clutch? If I push hard on the trootle from a stop it looks like it slips the clutch and it doesn't go anywhere?

Any ideas.

Thanks
