ECU , gearbox not communicating
Hello everyone , I am asking for help and advice . I have owned my 2007 3.0 TDI for about 9 months . During that time it has been working perfectly. Then 4 weeks ago I pulled off the drive , got 100 yards and it stopped without any warning . It would not start and there was lots of smoke . I called for a recovery and the mechanic plugged I a diagnostic lap top and it indicated a problem with the no 1 injector . I had it taken to a local independent VW/Audi garage . They confirmed a fault code showing an injector problem . I had the injector changed at a cost of £500. The car failed to run .The mechanic suggested there might be an issue with the ECU . I asked if the unit be sent for testing . It was and the company advised that it was damaged and unrepairable . With reluctance I agreed to order an new ECU, for £1500, which had to be obtained from Germany . Now on the third week no calls , so I rang to see if it had arrived . They informed me it had and they had loaded the software . Put it on the vehicle and the engine ran perfectly . HOWEVER it will now only select 1st and third gears. The manager of the garage informed me that the gearbox is indicating that there is an issue with the engine. They now have little idea of what is causing the problem . They suspect it could be a software issue . They loaded the latest software . They have contacted VW and are waiting for a reply . Could it be that the latest software is not completely compatible with my vehicle and it needs a earlier version. They are going to reflash the ECU once they get a reply from VW. All this is very depressing , and I worry about ever getting my car back and mounting costs eventually making it unviable to repair, which is a shame as I like the car . Any help appreciated .
