A little update for you...changed the turbo, egr valve, vgt actuator, ebp sensor, Baro sensor, fuel filters, and oil cooler. I talked to the tech and he said they did the master reset after the turbo and EGR. Made a trip of about 70 miles with no turbo problems at all. The turbo sang the whole way with no signs of not spooling and no deeper exhaust note. The next day, I was driving 20-30mph through a neighborhood and I noticed the turbo wasnt spooling, the exhaust was deeper, and the service eng soon light came on. I got codes P0236, P0299, P0470, P0107. Got back to the house, shut it down and started it back up, everything worked fine, no codes. Drove home the next day and until today have had no problems with the turbo and no codes. Whether or not this matters, I turned the edge tuner up to #1-lowest setting from the stock setting on the trip back just for the hell of it and have had it on that since. Today when leaving work I noticed the turbo was spooling but it didn't have the pep in its step. Seemed like it wasn't getting the fuel, maybe from the tuner. A few minutes later, the turbo stopped spooling the the exhaust got deeper. Went straight to the dealer, they put their computer on it and got a P0401 code. He did the EGR test and turbo test and all passed. I'm out of suggestions, could this be my Edge tuner going whack?? Could the EGR valve be faulty?? I'm open to anything at this point...any suggestions...PLEASE!!!!!

 

I have the same issue, it happened this summer pulling a heavy load. When truck went to OD/Lockup lost all boost and deep exhaust sound and black smoke. Minutes later all came back. Since then I have had the exhaust sound, what appears to be sticking turbo. EGTs have been higher along with coolant temps. Does not take much to make them rise. Driving in town stop and go and the coolant seems to get around 200- 210. I have changed the EBP sensor and the EGR valve and still having the same issues. Plan on pulling the turbo and cleaning.

Have you found any more out with your problem.

 

I think 0470 and 0299 were the codes I got and replaced the EBP sensor and all is fine. I know you replaced it but the elec connector/plug is known to fail and the tube running to the EBP sensor can get plugged up. Just a thought. If you haven't take a look at the EPB senor plug and make sure its not dirty or bad. Also if needed clean the tube going to the sensor. That EBP sensor can cause all kinds if whacky troubles including your turbo.

for starter it helps if you list the code and whaty it means. there are lot of code's for us to remember. sometime we get it right somethimes not.
p0236 turbo boost performance
p0299 turbo under boost
p0470 ebp ckt
p0107 map/baro

all the codes are related to either the map sensor or the ebp sensor. I know you say they are new. However you really need to know what the pressure vauve of them are at koeo. and you need to also look at the baro and they should all be with in a few
tenth of each other.
with out that you not going to get far.
if you cant that info. as stated in this thread disconnect the ebp and drive it see what happens when the pcm is in default.
remove the ebp tube and check it and the manifold port for a blockage.
you may also want to replace the ebp connector as that is a knowen sorce of concern for what you have going on.

 

Could the VGT solenoid on the turbo be an issue. Could we be foaming oil causing an issue. from the guys having this problem what oil are you using. I am 5W-40 syn and my problem was during really hot temps outside. Just a thought. Woo is in Texas and AMGPRO is in Cali

 

I havn't changed the MAP, would that have anything to do with it?? Also, what are your thoughts on the cat converter being plugged? Two techs have told me that could be a possibility...? When I unplug the EBP is it ok to leave it for a day or so?? It sometimes doesn't happen immediately.

 

Yes it would be ok to leave it unpluged for a day or so. also as stated earler you will get a code and a check engine light when you do this.
It could be a map sensor or a map hose that is cracked. we dont see many map's fail. see lots of hoses.
the majority of failed cats well have reduced boot and excessive lag as well as hard and delayed trans shifting.

 

I use 15w-40 rotella non-syn. It did it both when hot last month(95), and today with a high of only 80.

 

Hey Cheezit, thanks for all the help. Today I'm going to the dealer, going to have him check the pressure values of the Baro/Map/Ebp sensors with KOEO. I'm going to have them replace the EBP connector, check for a crack in the MAP hose. Does it matter that for some reason the truck ran fine for the last 4 days, no codes no problems...? Any ideas why that might have occured??

 

Went to the dealer this morning, had the tech replace the EBP connector, checked the MAP hose for cracks, and also pulled the tube and checked the block. All ok. Also had him run the pressure values KOEO for the Baro, Map, & Ebp. Here's what it was showing:
BARO ~14
MAP ~14
EBP ~17-18

We also pulled the EGR valve out and it was covered in soot. Bear in mind, this valve is two weeks old. We also noticed a lot of soot in the EGR cooler which was a lot cleaner three weeks ago according to the tech. So I'm ordering a new EGR cooler and a new intake to clean EVERYTHING and start over fresh. I dont know what if anything it has to do with my problem, but it cant hurt. Anybody see anything wrong with the pressure readings above? I know cheezit said they should be around a few tenths of each other...

 

In central cali during the summer it can get as hot as 105, sometimes hotter. I use royal purple 15W40 syn. I took my turbo apart and ordered a rebuild kit from gpopshop.com. My unison ring had a big wear spot so I ordered a new one thats been updated. All inner and outer edges have a bevel to keep them from binding. I think my problem is/was the turbo sticking. I am updateing the STC, dummy plugs and stand pipes along with installing an egr delete kit. I will post my results once I have everything back togother this weekend.

 

Being in California and subject to some very stringent emissions inspections I would advise you to NOT do an EGR delete at least until you give the turbo a chance to work correctly. You're going to NEED your EGR to pass inspection

 

I just had the truck smogged so I have some time before the next one. I also have friends....if you know what I mean
