J.C 10 Posted June 3, 2013 From what I can gather, relay 53 is a standard relay and could control a multitude of things, I'll have a look at the wiring diagram and see if I can trace those colour wires Steve ---------- Post added at 1:28 AM ---------- Previous post was at 1:11 AM ---------- Looks like it could be J208, (HO2S) heated oxygen sensor control module, which supplies voltage to G39 HO2S heated oxygen sensor, when the engine control module power relay is energised red/yellow wire supplied from fuse 18, to confirm check voltage(to earth/chassis) at R/Y wire with ignition on, (12Volts), then remove fuse 18 and test again, should be 0Volts Steve Quote Share this post Link to post Share on other sites

Thanks! It's my Lamba that isn't working. ---------- Post added at 8:30 AM ---------- Previous post was at 8:29 AM ---------- Electric windows. I thought the window relays were behind the rear panel?
