Mngl450

Hello Mercedes owners,

This is my first Mercedes. Love everything about it so far except the airmatic.

I installed new air struts in the rear last year. And new ones this year. The 2008 GL450 has 120k miles on it. After installing the new front struts the GL no longer goes into the 'raised position'. When i push the button tge compressor ru s for a minute and then says it is iverheating. The compressor also runs very frequently. The suspension sits well and doesn't move up or down or leak anywhere. I also get a malfunction warning on the screen periodically.

Anyone have any advice?

I'm stumped, and can't find a thread relating to this.

Your compressor is going out. Very common at that mileage.

Thanks Blown V8,

Have you heard if the Arnott compressors are a good buy?

Anything Arnott is good. No, I am not affiliated with the company.

Agreed. We used them to replace our S430 - 5 years later they were faulty again and Arnott replaced them free (we paid labor). Can't ask for more.
