That is what Im now seeing. After the y81 recall + the truck went through a regen and during that regen I drove it harder that usual in an effort to bake any off. I know the regen has nothing to do with the SCR but I figured the additional heat from that process could potentially help bake/burn...

I know this is an old one but I’m in the market now for a tune/mods and seeing that you have had the 2 tunes that I’m looking into I’d be curious of your review comparing them. I have been set on going GDE and have just been waiting till I was closer to my 100k warranty expiring but now I’m...

Things like this are beyond annoying. People being lazy and just trying to rush through things. I didn't have a CEL but recently dealt with similar issues with a body shop just slapping things together.....had to go back 3 times.

where are you guys buying the spare PCMs from? Looks like the sort is discontinued and I want to get my hands on one ASAP. I know there was a long conversation on here about the PN and where everyone was ordering from I can’t seem to find it. This is the correct PN 68256850AA?

Been looking for this one for a while. Found the e39 m5 hot wheel. Now hopefully they eventually make it in blue!

After cleaning the downstream Nox sensor it does seem to function. I just don't know what a good reading is but its not throwing any codes so I can only assume its good? It reads 1-5% of the upstream Nox but when i stand on the throttle it reads much higher and will stay high for several seconds...

I'm currently at a loss. I cleaned the NOx sensor and the CEL went away. I had the DEF recall done yesterday as well. I'm not convinced the Truck is ok, especially based on the mechanics responses to the residue in the exhaust. They want the SCR and DEF injector replaced and said it "should" be...

Dealer suspects failing scr and that’s the residue I’m seeing in the muffler tips. I put a camera in through the down stream nox sensor and the quality is rather low but it does look like it might be clogging up. Hard to tell. Anyone ever drop the SCR and clean it or have a baked?

DEF injector looked clean. DPF look filled with white(DEF). One of my scan tool had live data feature the nox sensors and it looks like the downstream sensor might be bad? Anyone know what these should be reading? NOx was just sitting at 65535 and didn’t budge.

Mine doesn’t look too bad for 82k but the inside of the DPF didn’t look great. Really hard to see in there.

Truck has had some strange things going on over the last few weeks and unfortunately it was in and out of the body shop with issues so I haven't been able to diagnose or take it to the dealer. Since then I also rolled over 80k so the emissions warranty might not help. I noticed over the last few...

Truck was in and out of the body shop for unrelated issues the last week. They were troubleshooting to find where the coolant was going with no success. About 15miles after I picked it up I got a CEL, P20EE. Anyone deal with this yet on the 3rd gen? I haven’t had the recall done yet for the DEF...

Yes, always ran the Mopar filter ordered from diesel filter online.

My 80k oil report. Seems pretty consistent over time with aluminum. Still haven’t found anything on where the coolant went but it has seemed to slow down and maybe even stopped. Other than that, truck has been pretty good so far.

That sounds good then, maybe I shouldn’t be worried about what I’m seeing then?

Just wrapped up a 1800mile trip and it seemed to have poor fuel economy and consumed a lot of DEF for what we did. Averaged 22mpg which is terrible but I had 4 bikes on the back. Maybe they acted like a sail? I’ve averaged that towing 5-6k before. Also used just under half a tank of DEF. Today I...

Would these leaks be visible if I were to crawl under the truck or would they be internally leaking?

I had something similar and I did a pressure test myself with no luck. System held 25psi for 45min. I’ve since been monitoring coolant levels but i dont drive as much and in the last 2 months it’s been fine with no drop. Initially I lost maybe half a gallon over 12k miles. No leaks found. I...

The BMW costs do add up sometimes. I try to do as much as i can myself and they arent daily cars so it hasnt been to terrible. The cost of E39 parts has gone through the roof recently. Ive owned the E39 10yrs now and its been relativly cheap as many 5series part work for it. When i bought the...

Ya the 4k interval doesn't sound like a solution to me. Now even if do that and at 4k its the same or even more then its pointing to some kind of growing issue. I do take the sample from the drain and i know there has been discussion on this. The samples are just for me and It provides a nice...
