SlS problems

Henry.adams · Mar 23, 2023

My d2 airbags won’t inflate on the left side even if I do it manually with nanocom but if I swap the plugs around then the left will inflate and the right won’t. I’ve already replaced the the pump and the bit the plugs go into. No faults shown. Anyone got any idea

Have you changed the ride height sensors? common fault.

I presume that by "plugs" you mean the connectors from the air supply solenoids and if it's so means that there's a wiring issue between the ECU and the plug for the LH side solenoid or the ECU is fubar cos for an open circuit there it should log a specific fault code even though nanocom used to miss SLS codes from time to time but the SLS warning light should be on any way. You have to make a continuity test on that circuit. Bridge the pins in the LH side plug and check continuity first at C0391 across pin 5 and earth(disconnect it), i've seen cases when it was bad contact in this connector, if you have continuity to earth there you'll have to check continuity between that point C0377 and the ECU's connector C0655 oin 3 (white/yellow wire all the way) If no continuity 0391 to earth that's the problem cos the wire is interrupted to the solenoid . I hope that the diagram is accurate as i've seen mistakes in RAVE not once

Thanks mate Coil springs looking real tempting right now

. I don’t think it’s related but half my dash lights aren’t working either so I won’t see a warning light on the dash anyway.( probably just a fuse or something I haven’t looked into it at all yet) I will start by looking for damaged cables close to the compressor as is my last compressor melted it’s self so could have damaged the cables

check fuse F27 in under the dash
