Hi all,
Recently joined the forum so be gentle :-D
OK, had an A3 in for repair with DSG issue with the usual PRNDS lights flashing. Read codes and came up with Solenoid N88 Open or short circuit to ground.
After lots of reading up it all pointed towards faulty links inside the mecha unit so luckily I'm in the electronics game so no big issue for me.
Removed the unit and removed the cover on the ECU of the mecha unit and two wire links has become detached from the PCB..great...I thought!
So, repaired the links, checked continuity and resealed the unit and fitted it back to the gearbox.
Turned on ignition and not lights flashing, switched on engine and PRNDS flashing again. Scanned and same N88 fault appeared. So, proceeded to clear codes and then lights stopped flashing but still not Reverse gear or 1st gear, only 2nd gear, which I think is a limp mode.
So, reading further on it was suggested I perform the Basic Settings, went to group 061 and hit GO but It just comes up with ERROR., same as 062 etc etc
Doing further investigation I can see Supply voltage 1 at zero volts and Supply voltage 2 at battery voltage when engine idling...
So, where are these voltages fed from and would this be stopping the procedure of 061?
Thanks for all your help
