Hi Everyone,

First of all Merry Christmas!

More problems with my car! I have a 2006 Audi A6 7 speed Auto 2.0 Diesel.

While driving the other day the engine management light came on. Everything seemed fine while driving. I parked up thinking it was glitch hoping the the error would clear by the next day but it did not. The next day I could not put the car in reverse. The gear lever oult not get out of park, so I used the override button near the gear lever and was able to get the car into gear. I managed to get out of my drive, but later on in a car park I tried to reverse into a parking space and put the car in reverse. As I tried to accelarate and the engine just reved and the car hardly moved. After around 5 seconds the beeped into reverse and let me reverse.

I did some testing. I tried to put the car into reverse and sometimes it took a good 5-10 seconds before I heard the reverse beep and the car engaged into reverse. A few times it really clunked/jerked into gear. I seems like I have to put it in gear and wait a bit before trying to reverse.

I managed to get a diag done on the car and it showed the following. I did get the codes cleared thinking it may sort the problem out but it did not:

After getting the codes cleared and drivng the car for a few day I got another diag done, but nothing showed up as an error, bit I still have the problem.

Any ideas on how to fix this problem?

Thanks

It sound like Multitronic(valve body)has a bad solenoid. Or needs to be replaced.
