2 thing that worries me in the repair history:

suspension strut,air spring
pressure line, compressor

from what you read on the vmi report, is the frequency and severity of repair normal for a 2011 e350 with 30k miles?

I read some 2011 e350 vmi reports before and they were lot cleaner.

Thanks much and happy

 

2011 E550s all came with Airmatic suspension, and there were problems with air struts. Both rear struts on my 2011 E550 leaked enough to need replacement (under warranty) - the replacement struts have (thus far) been more reliable than the ones installed at the factory.

I can say that, aside from front rotor issues (there's a TSB) and leaky rear struts, my 2011 E550 has been trouble free.

 

I had to have a rear strut replaced on my S350 for a leak with less than 10k miles. Done under warranty and fine since. Often, when an air shock leaks, the compressor will work overtime to keep it inflated. This can cause unnecessary wear on the compressor. Ithink the VMI report shows that all the components were replaced. That is a good thing.
