History is that car was working perfectly except ac/heater fan had failed.
I was asked to look at this and found the LIN bus for AC was being dragged down by a faulty AC pressure sensor.
However workshop owner (who previously owned this car) was begging me to update all control units if possible as car is now owned by a friend of his who is planning to export it to a relative next week on Friday. didn't really want to flash controllers without a reason, but I could understand his point of view that if it didn't happen now, the car would never have a chance to be updated again and he was almost begging me so I thought I would do it.
Only updates I could find were for 02-Auto Gearbox, 17-Dashboard, 19-Gateway, and 61-Battery Regulation.
Gearbox update failed but all others updated fine. Tried gearbox update again after flashing 19-Gateway, also tried to reflash original firmware back which also would fail as well.
However the failed gearbox update seems to have caused a serious problem - I can still find a gearbox module and part number using various diagnostic tools, but cannot read fault codes or change coding. Even though I can still connect to gearbox ECU via diag tools, or to try and reflash using ODIS-E, I cannot move gear lever anymore (stuck in P unless using emergency override), and many other modules (e.g. Engine, Parking Brake, ABS, etc.) have faults stating no communication with gearbox.
Tried using two interfaces, and also tried all relevant options I could find in ODIS (e.g. reducing baud rate to minimum).
I asked a friend if he could send someone who has online access (Geko account?) for ODIS, but the person said it was likely the issue was because I used ODIS instead of VAS-PC.
However the other modules for which I could find an update worked fine using ODIS.
When I look through the logs, the only relevant error I can find is:
Result : Flashen der Datenblöcke fehlgeschlagen.
My plan is to go back on Monday with VAS PC and see if I can fix it. If not, then next idea is to call in friend of a friend who has Geko (online ODIS) account, and if that doesn't work pay for dealer to fix it (which I don't really want to do as I suspect dealer will automatically decide to fit new mechatronics plate at my cost).
If anyone has any ideas I would be very very grateful for suggestions.
