Hi all,

i have a 2004 A3 2.0 TDI With a DSG gearbox, the car has done 130,000 and I use it to keep the mileage down on my A5, the car has been fine but last week it suddenly lost drive (like dipping the clutch) and the gear indicator flashed, stopped the car and re-stared and all was good again, but the problem kept coming back.

VCDS had a gearbox code and description of shift solenoid 5 (N92) open or short to ground, so swapped it out with an eBay one, changed the oil and filter and tried again but got the same fault after about 20 min of driving 

the car isn't worth more than a grand so if I can't resolve it myself cheaply it will go up for spares or repair but if anyone has any any advice that would be greatly appreciated, I was going to take the mechatronic out again and give a good inspection of connections etc

certainly worth checking all connections as you suggested but also worth checking any wiring that you can easily access if the solenoid has lost signal.

I have the Mechatronic unit out now and have checked the resistance of the N92 solenoid but its fine (around 16 ohms), I'm going to have to break it down more to investigate further
