Glow Plug Control Module - Compatible with 2007 - 2008 Mercedes-Benz R320

I had codes showing for the glow plug module and two cylinder glow plug shorts. If the module code is coming up, go ahead and try this first because it can cause misleading glow plug codes as well. It costs more but it was right in front of the engine with only two bolts and click your two plug ins on and it fixed my problem. Van was extremely hard to start when under 45 degrees so yeah this did it. Quality didnt seem quite as heavy duty but it was the same manufacturer of the original and everything fit nicely.
