A4 2006 Auto Gearbox problem-Help!!
Hello all,I need guidance/advice. My Audi A4, 2006 with multi tronic transmission initally started jerking whilst I am driving in December last. Initially it was a minor jerk at first, if I am driving, I could feel a slight jerk/shudder at gears 5,6. I thought it may be due to the cold weather or bad diesel and perhaps the fact that I only drive it at weekends- rest of the day its parked on the drive. I took it to Audi and had the gearbox oil changed due to the mileage was 79k . No code was coming up after diagnostics. The gearbox oil was changed initially at 39k. The jerk stopped after the gearbox change but last weekend, was about to reverse and put the shift on R only for the car not to budge. The dash indicators,PRNDS started flashing. After switching off and waiting a while, I restarted and managed to engage reverse and drove the car home. Booked to see Audi in 2 weeks but need to know what I am dealing. I have an OBD tool and ran a diagnosis and got this code 017090. It appears to be the TCM- however info on the web indicates that it may be the beginning of an unending journey to Audi for expensive repairs. Will appreciate any thoughts/experience/help on how to deal with this problem.
