DPF full and manual regen

To start off, I'll just say when anybody asked me about my Cruze CTD, I always gave it high praise. I should also say I'm a retired GM employee. The car is 1 2014 model with 67,000 KMs on it.

I went away for two weeks and when I left the car in the driveway, all was well. When I got home, I went to go pick up my dog. At the start of the engine, I got the "DPF full, continue driving" on the DIC. about 30 seconds later, the CEL came on. I checked the code with the Torque app, and it was P2463, Diesel Particulate Filter Soot Accumulation. At this point I know that it has to go to the dealer for a manual regen. I also know that there has been a emission recall (15594) for this vehicle but there are no parts available apparently.

I take it to a local dealer (not the dealer I bought it from or had previous work done at) just because I thought it might take them a while to do the work and being close, they would drop me back home. When I brought it in, I made it clear that I thought this should be covered under the emission's warranty and was told it would be. Later that day I got a phone call telling me there were two additional codes for the EGT sensors. Also the technician found that the cooling fan was not functioning. I was told that all items would be covered under the emission warranty. I got a call later that day telling me that they couldn't locate a fan in the parts system and the fan would not be covered under the emissions warranty. I had a discussion over this and asked for a contact number from GM Canada because I don't agree with this. I was told I would be contacted the next day (Saturday) for an update on the parts. I called the number and it turned out to be the GM Customer Care number. I explained the situation. My view is that since the emissions can be affected by the engine temperature, it should be part of the emissions warranty. Also, how can the vehicle be brought back into emissions compliance if you can't do a manual DPF regen without the fan. She said she would look into it. I didn't hear back from the dealership until the Thursday of the next week. They said the fan could take up to 2 months for delivery.

On the Friday, the GM Customer Care person called to say that GM would not be covering the warranty. I could tell that she was reading off a scripted response. I asked for someone higher up in the Sales and Service department of GM and was told that there wasn't anyone else.

On Monday, I drove to the dealership to find out what my cost on the fan would be. As a GM retiree, I get a discount. To my horror, my price was over $1000. I then told the service people I would be taking my car home until something got sorted out. They then presented me with a bill for an hours shop time. To say I was unhappy doesn't cover it. I paid the bill just to get out of there. I told them I'd be back in a couple of hours to pick it up and asked where the vehicle was parked and took the key.

I came back, found the car with the hood popped. I opened the hood to find the fuse box cover missing. I found the cover inside the car along with a test probe from the technician. I drove around to the service managers desk area and gave him the test probe. I dove home which took around 10 minutes.

When I got home, I popped the hood because I wanted to see if the technician actually checked whether the fan was bad or the fan module. I then noticed that the front EGT sensor was missing. He had removed it but not replaced it. The connector to the fan has never been apart so he didn't check whether it's the fan or fan module. I called the service department to ask "WTF", only to be told that I shouldn't have driven it home. Nobody told me that when I picked it up nor is it written on the invoice. They don't know where the sensor is because the tech is now on holiday.

A few days later, I get a call from the dealership asking me if I was satisfied with the service. I went through the whole story to have her say she would look into it. Today, I get a notice from the dealership, inviting me to do more business with them. Are they insane?

My next course of action is to file a complaint. How can the active shutter system be a monitored OBD2 emission system but the fan is not?

Indeed this looks like a horror story, they have no clue where to look under hood....that's pretty sad GM

Not sure I've ever seen a fan listed in a emissions warranty before - but you do make a point.

However, the fan is covered by GMPP.

Regardless, the problem is a bad dealer service experience. I'd be tempted to name names.
I should add that @diesel has worked out what is the cause of this DPF full and manual regen required situation.

Hopefully he checks in soon.

park brake should be covered by emissions then. ;)

Does GMPP cover a parking brake as well? :jump:

Spoken by the guy who doesn't GMPP...

I'm not sure. But I bet that fellow GMPP guy @Eddy Cruze will know.
Do you have the part number for the fan 1G seems excessive.
Did he check the harness, fan, module and the fuse block connectors?

Let's just talk about parts that are not covered!

Start keeping a paper trail for small claims court.

As for the fan, it appears the diesel model uses a different (and far more expensive) fan.
Link. The LTZ model only costs $150 or so.
Gm part number 13338843 is $790 list price is the diesel cooling fan

First off, here is what happened to your car:

http://www.cruzetalk.com/forum/201-...sel-owners-read-can-save-you-trip-dealer.html

You don't want to drive too far with a full DPF, as it will eventually get to where a manual regen cannot be done.

Now, the EGT sensors are not related to this, but they are the single most common failure item. In fact it's the only emissions component I've ever needed to have replaced. It happened to me at 61K miles and it was covered under emissions warranty. Others have not had the same luck.

As for the fan, you should be able to observe its behavior watching the engine run. AC on, AC off, etc. You shoudl be able to see it cycle.

There is a lot of discussion on this forum about incompetent dealer service departments, especially when it comes to the diesel Cruzes. Small claims court would be more trouble than it's worth. You might be able to reach out to GM customer support on this board for assistance.

@diesel , he did get a hold of GM Customer Service to no avail.

To the OP, did you check 5 hose clamps on air cleaner/turbo? Causes a lot of CELs.

Yes, but not the folks on this board. Might possibly get a better resolution.
IndyDiesel - Since a brake cable is not a system controlled item, it is not covered by an emissions warranty. Paraphrasing the C.A.R.B. Act of 1967, any controlled system that can affect the emissions output of a vehicle has to be monitored by the OBD2 system. Hence the reason for the active shutter system being monitored.
I still haven't heard back from the dealership as to the whereabouts of the EGT sensor that they removed.
DslGate - It isn't the clamps on the air inlet.
I should also say that I do have some additional knowledge on these systems. The last few years at GM, I worked on the DEF calibration for the 2016 full size trucks and the new 2016 Colorado diesel. We managed to fill up DPFs from time to time by over injecting DEF into the system.

Very important information.

Wouldn't the DEF be injected downstream of the DPF? My understanding is that diesel fuel is what's injected into the DPF.

Actually on the Colorado and the full size trucks, it is injected just behind the catalytic converter. On the Colorado, the DEF tank is just in front of the spare tire and then there is a long injector line that winds its way to the outside of the passenger side frame rail and then back to the inside of the frame rail to go to the DEF injector. On the full size truck, the DEF tank is already up at the front so the line is short. We spent a lot of time dealing with line restriction/pressure loss concerns with the Colorado.
