Review on 🔌 Dorman 904-310 Diesel Glow Plug Control Module for Compatible Dodge, Freightliner, and Jeep Models by Paul Lee

Easy replacement for my 2007 Jeep Grand Cherokee 3.0L CRD engine (Mercedes OM642) with Bosch 4.4V glow plugs Works great. for some time. I bought the first one in 2015 (along with all the glow plugs), it started to fail after 6 months. With a lifetime guarantee, Revain has provided free replacements. Now, 20 months later, the second unit is out of service. I called Revain and they told me they are no longer taking this part from the previous source due to many bug reports (the part is listed as the same but now from a different source). Replacement #3 is on the way - hopefully it lasts!
