|
On my 88 635csi the check engine light comes on when it is warmed completely up, i'll shut off the car and let is cool off, and the light is still there. BUT if i disconnect the battery for about a minute or so AFTER the engine is cooled off (to kinda reset everything) the light is gone, untill it is yet again warmed up.. any suggestions as to what this might be? i'm personally thinking its oxygen sensor. but if anybody as any suggestions, please let me know _________________

You may need to take it to a dealer, or well-equipped indie, to read the stored codes. _________________
