SLS troubleshooting
I’m not sure if my SLS is working properly. Honestly there’s not much information about it, everyone just gets rid of it and I don’t wanna go that route. I figured my SLS pump was running all the time, I’m not sure if that’s expected behavior. There was a small leak underneath it so I decided to rebuild it. I’ve purchased the kit from Ray and installed it. Today I mount the pump back and refilled the reservoir with fresh Febi M6162. The leak is gone, I let the pump run for like 15 minutes and seems to be working fine as the fluid level went down from max to min. Ride height went up about half an inch. But the pump kept running, it turns off for a while only once I hit the brake pedal. Is this normal? Once I turned the ignition off fluid level went back from min to max in like 5 minutes. I don’t see any leaks on shocks or anywhere but I’m still not sure if that’s the way SLS should work. Here is the stance of my E24 before pump rebuild. Is it normal or low?

Re: SLS troubleshooting
Hard to say with a picture on a dirt surface. But the tire to fender opening would suggest it's off. I'll show my vehicle as reference, but I can't vouch that it meets factory trim level.

Re: SLS troubleshooting
I'll update this thread since I am now also needing to troubleshoot my SLS. Further investigation provided the following.
From the factory repair manual section 37 page 3:
From the factory specifications manual section 37-12:
My system is now randomly dropping/raising so I'll have to do some work...

Re: SLS troubleshooting
Just noticed I posted the E32 spec! Disregard that and use this specification information.

Re: SLS troubleshooting
Didn't notice this before, but it's interesting that the M6 measured height is greater than the base 633/5 by 10mm. I assume the base vehicle had higher profile tires (non-TRX as well), so possibly the ground-to-body measurement would be the same between the base and M6?
