One thing I do when at the dealer is ask "do you guarantee this will fix the issue, or are you just testing the part". That normally gives you all the information you need on if you should proceed with the repair or not.

 

It's there.

Modules, ecm then advanced diesel controls

 

Wow, thanks! I am blown away at how extensive and capable that gretio program is. I found a youtube video where the author did a "flush" of the DPF while it was on the car and it cleaned out the system enough to pass smog. This was on a Range Rover, and I think it was Scotland. But the concept is the same. I also never knew there was "DPF cleaning fluid". One thing I also noted, the intake manifold is caked with carbon dust. I might just remove it and clean it out too. I just need to get this thing to smog again.

 

I'm pretty sure they're a spammer based on their one other vague reply to a thread from March.

 

Welcome Aboard!

Don't forget to introduce yourself and your Cruze here.

 

Low performing dpf is under hood in front of engine not the scr.

I'd suggest getting Gretio on your phone and doing a service regen assuming there are not other stored codes that need to be addressed first.

Gretio is a service tool that has many bidirectional controls. Find in the play store or whatever apple has.

If you search for gretio on this app you'll find plenty of info.

Also this probably should be moved to the technical discussion.

 

Thanks, the dealer did the service regen twice. That was the only thing they could find with their computer. The "Diesel particulate filter full" message was more a symptom than the problem. The intake blowing off the throttle body caused the messages. Also thanks for the "Gretio". I have a good (not great) scanner, but not one that is bi-directional. I cleaned a lot of soot out of the intake manifold yesterday with a toothbrush and a vacuum. I intend to clean the DPF sensor next. I'm assuming it is one of the sensors after the SCR neat the rear of the system. The service manual really misses the boat on this issue. And I'll look to technical discussions as I learn how to maneuver around this site. I do love the diesel cruze.

 

Welcome

 

Thanks, I agree with you regarding most dealers. I have never, I repeat NEVER had a good experience with a dealer service dept. My first mistake was not doing my homework in the first place and doing my own forced regen. So after bitching at the service manager I let him talk me into bringing it in for them to look at it one last time. They also left the bottom radiator hose loose when they replaced the "Charge Tube" for $1100!, They accept no responsibility, typical. So the diagnosis is replace the DPF. They even offered to order the part which I have since learned that is no longer available, Nobody has them, I ordered on from a gm parts site only to have it cancelled due to lack of availability. I spoke to a California DMV referee regarding the issue. I'm told go fail the smog test, then send that report to them. At that point they will tell me the car is no longer able to be registered in California. What are my options at this point? I'm waiting for the dealer to return my carI. I will try to do the dpf reset as you indicated with the gretio. It's a great car, but this is so frustration. I would go so far as to register it in another state just to have it on the road again but that doesn't seem to be an option.

 

The gretio app is pretty complicated. I'm having trouble finding the "reset" for the dpf. I did see however a flush for the dpf after a reset that will hopefully work. baby steps. I have to find out how to reset the dpf as if I replaced the old one.

 

Is there a complete list of the controls available for our car on gretio?

 

That is quite an app! I am going to fail my smog and the dealer is going to diagnose the DPF as needed to replace, but it isn't available. I'll get a wavier so I can get it registered. However I need to keep it working. My guess is that the filter isn't plugged but I get too much particulate matter picked up by the sensor after the SCR. I'm pretty sure the sensor is reading a number of 12 for that and I don't know where it should be. I also need to know how to monitor the pressure going into the filter to see if it's plugged or if there is just too much particulate matter flowing to the rear sensor. I intend to remove the intake manifold and clean out all of the soot that's in there, then remove the DPF and the rest of the exhaust system to try to clean them out as well. If that works I'll do the reset and be good for the future, if not, and running the car won't hurt the engine, I will just keep driving. If the car will countdown to limp home mode, I may try the "Scotty" trick of using a 1 ohm resister to bleed down the memory of the ecm for a factory default setting. ( a one ohm short between positive and negative for 20 minutes). I do like that car and want to keep it going, it's only got 100k miles on it. My wife's Trailblazer is at 403k miles.
I will be doing a video of all the work I'm going to do. Hopefully it's not in vain.

 

That's a pretty vague request. Are you looking for performance on the track or the ability to carry a load and pull a trailer? IMO the best used car deal is a corvette, from year '97 to year "what you can afford". I bought a 2003 in 2010 with 30k miles for $18,500 from a private owner. Understand , I am a chevy guy. But you aren't going to drive a vette around with more than one passenger, or carry a large payload.

 

Was it fixed?
