Mackpro Posted November 2, 2010 Share Posted November 2, 2010 Got your text last night but didnt hear the phone. As the other guys said, EGR cooler needs blowing/cleaning out.

JerryB Posted November 2, 2010 Share Posted November 2, 2010 holy canolie I hope we aren't seeing a repeat of days gone by coming up again. I still have the EGR plate in mine and haven't had a prob with plugged cooler and still no codes. The bearing went out in my fan hub and I've had to replace 1 headlight bulb outside of regular service since these guys talked me through the EGR and turbo problems I was having.

Mackpro Posted November 4, 2010 Share Posted November 4, 2010 I'm cleaning out an MP8 EGR cooler today and tommorrow. At least with the ASET its easy to remove and clean. With the MP8 you gotta pull the turbo and a bunch of other crap!

Lmackattack Posted November 4, 2010 Share Posted November 4, 2010 Yep you have a few big pulls ahead of you. Just drop another gear and keep the Rpms up. That last pull in WY and park city are pretty long. Have had to pull to the side a few times in the summer on those hills. I always start them with the fan on and cross my fingers....
