Another ABC Question

Good day.

The question:

My right front sits just slightly lower than my left front side when the engine is running. I'm going off visually wheel well clearance.
During the night resting it sits even a little lower than while running.
No error messages, no leaks, rides great.

Anyone else experience this.
Any informative information is greatly appreciated.

Thank you.

Could be a couple different things going on.

A bit of sagging overnight is often caused by tired or damaged seals in the valve block.

Variation in ride height, assuming no mechanical issues, could potentially be sorted by re-calibrating it.

Do you have access to MB STAR / Xentry?

Also, is the variation the same in the raised position as it is in the lowered position?

Thank you for the response.
Makes perfect sense.

Regarding the MB STAR / Xentry can you or someone direct me with a link on a reliable source on where to purchase? I'm going to purchase one regardless.

When I get home next week I'll test your thoughts on the raised and lowered position, if it is the same.

Stay tuned.

The BenzNinja will have you buy a specific Chinese clone, your choice of laptop and he will then install the software remotely.
He will also help you remotely diagnose problems.

So, I raised the car in position one and two. Really no discernable height variation.

Just started the process with benzninja.
