Hi Cheat22.

I have the same height issue with my 2012 R350. My passenger side front is about 1/2" lower than the front driver side. The rears are a slightly lower in the right. Was told by an alignment shop that I need new coils/front shocks, being weak and unable to complete the alignment. I believe he said the camber could not be set correctly.

Took to an independent mechanic and he disagrees due to my mileage of slightly over 50K miles and visually did not see anything wrong with them or any bushings. Also, when driving back from work each day and backing in to my garage while turning the steering wheel, I will hear a few clicks in the front suspension area. My independent did not see any issues and could not replicate noise.

Could you please update if the new coils fixed your lean issue? I might go ahead with new coils & shocks, if that fixes your problem. I also saw some people on youTube that their coils had broken near the base, causing noises.

Thank you. Hope it all works out for you!

Sure thing.

Hopefully they arrive before the weekend so I can fit Saturday.

Hi,

Finally got back home after traveling for a couple of months with work.

I'm not looking at these front coils and wondering if it's a job best left to garage.

Anyone any experience replacing front coils ? Mine is a 2007 r320 CDI.

Ok, so new h&r lowered springs now fitted...car still uneven!

My r320cdi is about 1 inch lower on the right side (both front and rear).

I have now changed:

Both rear airbags
Both rear height sensors
Air valve block
Front coil springs

I also added adjustable links to rear in the hope of setting differently to fool it into levelling.

But still car right side (UK driver side) sits lower in front and rear.

Today I plan to lower adjustable links more to suit new lowered front springs better, and will try offsetting again to get this thing level!

So far though, even a large difference in link lengths has not seemed to fix. In fact,I don't understand if these height sensors work that way on the rear only automatic?

Front deffo looks better on lowered springs though, just didn't fix this lean as I had hoped.

Does anyone know if STAR can recalibrate rear sensors? Or am I on the right track adjusting them mechanically? I plan to flip brackets today too, see if going even lower helps but I don't want it too low to ride crap.

Another quick update.

I finally got her all levelled out!

I turned the rear height sensor arm brackets after I straightened them out. I think someone before me had been bending them.

I then added a couple nuts as spacers, and set my adjustable links the same length. Voila... She now sits level!

So I think the issue was just bad brackets at back.

Now, it's lowered nicely, about 2 inch wheelarch gap all round. I might raise back a tad though.

Now another issue, rattle from front level..sounds like a drop link to me.... The guys may have bust it removing for spring
