VRTrickster 0 Posted October 31, 2010 Report Share Posted October 31, 2010 I have a lambda sensor fault showing up on vag-com ( 00525 ) Lambda sensor short to ground. It is not the lambda sensor at fault. I have found that out as I Im now on my third new Bosch sensor!All the wiring had checked out ok, but I attached some temporary signal wires for testing and still no change. The lambda voltage stays at 0.0v at idle and you only get voltage when I raise the revs up, then as they lower I see a voltage of around 0.5v then it gradually falls back to 0.0v.On the lambda % on engine measuring block 1 I have seen get as low as -3.0% then drop to 0.0v at idle. I dont think there is any fuel trim block on 032, but all the adaptation values for the lambda remain at 0.0%. On measuring block 008 there is a lambda reading and it reads -14.7v.I was wondering if the ecu is leaning the fuel off due to a leaky injector or something? I could really do with some help with this. Its really getting to me now Link to post Share on other sites
