Thread: SLS problem doing my head in

Yes, it seems that it drops on management request and in this case IMO it's a ECU missbehaviour

I can't understand that swapping out the ecu still has the problem occurring though? Unless as mentioned by SPROVER, the nanocom is corrupting the ecu in some way?
Really need to get it onto a testbook. Would a hawkeye bring up the error too do you think?

Hawkeye is on the same protocol with T4 and made by the same factory so it should show you a fault if there's any... anyway if you have access at least to hawkeye v.6 and you get no fault code support the body on two jacks at normal even level, go through calibration menu, and when it asks about calibration blocks confirm.... this would rule out a nanocom misscalibration issue too

by the way what values do you get in "target heights" section with nanocom? are they equal with the actual height readings when the car is on level?

Yep, apart from when the left randomly reads 000.
Otherwise they're always on par with eachother. And I can change their target height with Nanocom and it stores them.

then IMO better replace the left sensor and calibrate again or if the sensors are new it's a contact isuue on that circuit...did you check those plugs in the engine bay?

Have already done that, remember?

I forgot but but now it's certain that it drops on management request so there's the issue somewhere, at least swap the sensors between them and if you'll get that 000 reading on the other side it means that the sensor is the problem and if you get the intermittent bad reading on the same side it's the circuit cos as you say the ECU was ruled out.

It's the nanocom. Take it to a dealer and get them to set the height. Bet you a 6 pack it works
