In this video I show you how I fixed a common issue with the slow and long start issue with the 3.0 Litre Turbo Diesel CRD OM642 Engine Commonly found in many Mercedes, Chrysler and Jeep vehicles.
What you will see is that I step by step show you how to replace the Glow Plug Control Module A6421532079 with a relatively cheep non-OEM Module safely. In particular I have attempted to film all of the steps involved without avoiding the trickier elements of this task.
This is not a complex procedure, so you should have no issues!
Here is a link to the aftermarket Glow Plug Controller:
Amazon (US and General): amzn.to/3WC07DL
The tools used to undertake this repair are:
* 10mm E10 Socket
Specifically I demonstrated this on a 2006 Mercedes ML320
You too can do it yourself and save the cash!!

Outstanding video!! I’m going to replace mine as I’m having the same issues with my 2011 ML 350. Thanks from Wisconsin, USA

Thanks for the video! I have this problem on a 2008 Jeep Grand Cherokee, but it's intermittent. Most of the time it starts up just fine, but sometimes an extended crank followed by the big puff of diesel-smelling white smoke. Lots of google searching the issue... most discussions suggest leaking in the fuel system which seem implausible to me. My big puff of white unburned diesel at startup makes me think my problem is also glow plug controller.

I purchased a Beru for mine, mine is an 2007 Jeep so it has the steel glow plugs so it's apparently slightly different.

@@DrewFixIt The part you linked to was sold out and I had to order a different one. After much struggle, mine had some cables in the way, I was able to install it. It works prefectly. The car starts in a couple of cranks, even in very cold weather. Thanks.

Hi Drew, Hi do you know its the glow plug module and not the glow plugs themselves??

@DrewFixIt Жыл бұрын

Hi Mate, you can measure the resistance of the glow plus with a multimeter. If they are open circuit they are stuffed! From memory they should be somewhere in the 160 to 200 ohm range. Cheers Drew

For me, I thought it was the plugs, but control code came up too and a mechanic had mentioned the controller (after I had already bought some new glow plugs)

Did you have a fault code showing ?

Hi Mate, what was interesting with this one is there were absolutely no fault codes showing! Cheers Drew

I did the same job 2 months ago and no fault codes were present. If an OM642 has long cold starting then in the majority of the cases is the GP control module

Can you install a copy one in

Hi Mate, the part we installed was not OEM as Mercedes Dealership wanted like $850 here in Australia for the Genuine Part. We installed this one: amzn.to/3WC07DL Cheers Drew
