Need a shop - 2007 Jeep 3.0 CRD Diesel / Mercedes


New member
Hello everyone,

Let me first say, thank you for your help.

I have a 07 Jeep Grand Cherokee with the Mercedes diesel. It sounded like a good idea when I bought it but I've had nothing but problems with it. So far, I've been able to fix them myself but now I need to take it in.

I know this is a bit of a specialty item but it's also the same engine that is in the sprinter van. Does anyone have any recommendations on shops that are good, reliable and trustworthy?

Right now I have two problems one is a MAF check engine light. I've done what I know how to do. The other is a turbo issue. When it spools up it sounds like it is dumping all the air under the hood. I've checked hoses and all of that. Thinking maybe something with the waste gate. When I try to drive it I get the red lightning bolt that limits my driveability.

Thanks for you help,

I don't know any shop unfortunately. I am newish to reno, but you could try hooking up a pressure gauge to see if it is just dumping all of the boost. It should be easy enough to look up what the stock PSI should be.

I could be wrong but you may have a hard time finding a shop that will work on a vehicle with such a radical swap. I previously worked at a dealership and the shop guys (at least at my dealership) just followed the manufacturers instructions for everything. I don't think they would know where to start on a Mercedes engine in a Jeep chassis.

Hopefully someone else will chime in.

Edit: just noticed the age of this post. I am guessing you have moved on from this problem. Oops
