A5 OAW forward cluctch slip

Hallo

I m new, I am french and sorry i don t speak German.

I have a problem with my A5 2008 gearbox 0AW LAU, the forward clutch slip with the code vcds p1743, I do 2 oil changes because the clutch material in the oil.

After the clutch slip more, I disassembled the forward clutch, it was not very worn or deformed, I still changed the clutch, and it does not change anything.

I can do to make the adaptation but as the the light mil of the gearbox comes back and vcds code p1741, p1742, p1743 appear the adaptation returns in progress.

No problem with reverse clucth and no noise.

When the oil heats the car is less advanced, see even in advance no more

can you help me?

thanks
Xavier

Hi
Has the new clutch been calibrated correctly?
What gear oil did you use?

Hello,

first of all, you have used a wrong transmission fluid. For your 0AW gearbox you need a transmission fluid with specification G 052 516, such as Fuchs Titan CVT.

The clutch clearance should be 1,8 mm +/- 0,2. Try to get it down to approx. 1,6 mm. And also important, the pressure plate and piston as well as the oil pipe should also be changed. And change the external fluid filter.

In addition to that, you can open the hydraulic control unit and clean carefully the small strainers.

Regards,

Horch
