chaffingbuttocks 0 Posted October 27, 2005 Report Share Posted October 27, 2005 Hi there. I just bought a VR6, got a new battery and the car starts and goes fine once, but once you switch it off, when you turn the ignition, it revs for about 2 seconds then dies. have found that after the engine is disengaged, there is a little round plastic thing attached to the back right of the engine with a lot of cables going in on the right, and coming out on the left (going in under the engine cover area) that makes a whirring noise that doesn't stop. I have pictures but don't know how to post them. When i disconnect the battery for at least a few minutes, i am able to start the car again. any ideas? Link to post Share on other sites
SankysVR6 1 Posted October 27, 2005 Report Share Posted October 27, 2005 The "whirring noise" is the aux. water pump it shoud switch off after about 10mins thats normal.Not sure abut the starting problem Link to post Share on other sites
richievr 1 Posted October 27, 2005 Report Share Posted October 27, 2005 sounds like an immobiliser problem to me . . . .it'll start and then cut out after about 2 seconds if not working properlynot sure why it works once then doesn't . . .take it to vw and have a diagnostic done . . .

chaffingbuttocks 0 Posted October 27, 2005 Author Report Share Posted October 27, 2005 hi, thanks for the quick responses. This car does not have an alarm (not sure if it had an immobiliser unless it comes standard). I just imported this car, and when it arrived, the battery was dead so I changed it and it worked once, then not again till i disconnected the battery for a few minutes. Is it possible that the flat battery has screwed the immobiliser or the ecu chip? I heard that when you replace the batteries on certain cars, sometimes the ecu chip doesn't reset properly and it has some funky problems? Link to post Share on other sites
richievr 1 Posted October 27, 2005 Report Share Posted October 27, 2005 if your car is after 1995 then it will have a factory fitted immobiliser . . . . .if not then ?????????????????????????????it is possible you may have reset the ecu somehow - was the battery flat for ages before you put a new one on ???

chaffingbuttocks 0 Posted October 27, 2005 Author Report Share Posted October 27, 2005 I assume the battery was flat for ages, as it was on a boat for 2 weeks and it arrived flat. I have contacted 3 VW service places here and they have told me different things. one told me that the transponder in the keys need to be recoded to match the immobiliser, and another said that it can't be the keys cause it wouldn't start at all, so i will take it to a car electrician to diagnose the problem.

chaffingbuttocks 0 Posted November 12, 2005 Author Report Share Posted November 12, 2005 1 scan, 8 hours of labour and $600 later, the problem turned out to be a dry connection in the ECU. the solution? some solder.. and now to pass my warrant i need to get my ABS warning light to work too... and replacing the bulb didn't work so looks like i gotta get a new warning light unit..
