ArnottP-3214 Air Suspension Compressor-07-12 Mercedes-Benz Gl (X164)/ 06-11 ml-Class (W164)

I installed this on our 2008 Mercedes GL450, perfect fit, good quality, working nicely. Also replaced relay that came with the compressor as per manufacturers recommendation. It's a good idea to make some marks on the airline with a Sharpie, so you know just how far you've pushed the airline into the compressor fitting. It's been 1 week, so far so good.

Bon produit

Great compressor! Installed easily and has been working great. I’ve replaced my entire air system on my GL450 with Arnott parts and couldn’t be happier. Their warranty is second to none.

Install was easy and straight fwd. The pump so far, works well with no leaks and it very quite

Great fit and worked well for 3 months. Tested system to double confirm no leaks at other components. Even pressure/time test proved positive. Called Arnott directly to find most rude service person imaginable that told me they would not cover without written proof of purchase of not only pump, but also air bags. Contact through Amazon to seller has so far only brought email stating next available agent would contact me (2 days ago). Paid extra as claimed "built to last" and "engineered and assembled in US"... Don't be fooled as package clearly labled as "made in China". I suspected trouble as pump got HOT within first few minutes of initial testing.
