Thread: SLS problem doing my head in

Both were historical.

One was the exhaust valve as I had u plugged it to drive there.

The other was left height sensor connection broken or short.

I didn't get to write down the numbers quickly enough before they got cleared lol

If I had a list I'm sure I could point them out! I'll ask if he can upgrade it lol

The code numbers are irrelevant, that left height sensor code is the gist of it IMO, there's the probem on that circuit it's niot a calibration issue as long as it gets to normal level now and then

Would I have been going crazy if I was wiggling the wiring loom that goes along the chassis, and seeing the left sensor height reading go from about 140 to 160?
I don't think the compressor pumped during that time. Maybe a wire has rubbed through and is getting better connection when wiggled?

The fault code and the symptom are both pointing to a problem on that sensor's circuit, you should get hold of a known good SLS chassis loom or rebuild the wiring, they used to make tricks in the sensor's plug too

That doesn't sound fun to replace the full loom! I believe it does the fuel pump and other stuff too.
Perhaps I could splice in a length of 3 core wire closer to the engine bay, being I thought I saw the wiggling down the back adjust it the reading.
Stay tuned party people!

Well, at this stage the car has been functioning and drivable for the last few days *touch wood*

I'm not sure if it was clearing the codes with hawkeye (they were only historical), or a good proper wiggling of the wiring loom, but it's working.

The two sides are sitting at different heights by a bit, I'm scared to calibrate using the nanocom in case that did corrupt things!

I might still take it to a dealer, suck up the money it will cost and just get it done properly.

Thanks for all the input everyone has offered so far!

Had u thought of bridging the signal wire from the known good sensor, across to the faulty sensor. The SLS ecu would see the same height from both sides then. And would rule out a rooted sensor.

Might be time to get busy with the multimeter/test light and the soldering iron and make some repairs.

Definitely not a faulty sensor as I had swapped in a known good one.

I've know recalibrated using nanocom, so wasn't that either.

I'm confident that the wiring loom is damaged, since giving it a good wiggle it's been faultless since. I need to complete a permanent fix and put new wiring in spliced up further up the harness.
