OMG Such a confidence inspiring service department.I suggested possibly of ordering/replacing the NOX sensor and they seemed very reluctant because it was "too new" with not enough miles to go bad. They also kept calling it an oxygen sensor.
Have you reached out to customer service on this forum? They are pretty good about getting things resolved.I suggested possibly of ordering/replacing the NOX sensor and they seemed very reluctant because it was "too new" with not enough miles to go bad. They also kept calling it an oxygen sensor.
Keep us posted.Wife came home lastnight and said CEL had just come on , so pulled it out of the garage and hit the BLUE button , Dave from onstar came on and did the requested diagnostics. Asked me to write the error code down P11D7, after about 5 minutes he couldn't find what it was so he put me on hold and called GM Customer Care Canada. Doug was most helpful , after 10 minutes he couldn't find the error code , so he suggested that "we" call the dealer. I said sure, he dials through and gets Mike , Mike comes back with an answer . Nox sensor, so make a appointment. Wife shows up early and car went in that was 6 hours ago. Called an hour ago and was told they were still working on it.
IIRC, the federal warranty is something like 8/80. It's not as good as the 5/100 powertrain warranty unless you drive less than 10K per year, so there is potential overlap. Just out of curiosity, what is the production date on your car?Hi, I didn't want you to feel like you are the only one with this issue, after 7500 miles on my CTD my second CEL now, with the first one after less than 10 miles (different code). First one was the P24AE for a particulate matter sensor and now P11D7 which sound like a NOX sensor problem. Going to call dealer later today and see if they will order a sensor BRFORE I drop my car off, the last sensor took about five days to diagnose, order a sensor, and then install new sensor. I sure hope this isn't a constant issue on these diesels with the smog BS. Anyone know how long the emmisions are warrantied for? If its 36 months we're gonna be screwed with sensor problems on these cars in the future or a lemon law issue for sure.
So, has it stayed off? I think a couple people have posted that they saw this code without a CEL.Hi, don't have the car here right now to check production date but I bought it last quater of 2013 so I would imagine Sept - Nov 2013. I will check it tonight and update.
I checked the car at lunch and was suprised to see the MFG date of 4/13. I also called the dealer and got his voice mail. I left a detailed message but 5 hours later no call back yet. The wife picked me up to go to lunch, I was going to stop at the dealer in person but when I got in the car the CEL was now off??? One part of me is relieved and the other side is wondering if I'm in for a lifetime of CEL's and sensor problems.
Any updates?Thanks for the info guys. I just had the CEL pop up On my 2014 diesel cruze with 39577 miles.
When I went to a local advanced auto to read the code their reader said that I had 3 codes. All three where P11D7, with the first one saying "confirmed" the second saying "pending" and the third saying "permanent. "
Looks like it's time to call the dealer!
How many miles do you have now?I got P11D7 last Friday. After about an hour on the highway that night it cleared itself.
Then in today it came back again. We'll see how long it stays this time.
Do you plan on taking any action or just observing?And the check engine light just cleared itself this afternoon.
Keep us postedHad to take my wife's service dog to the hospital in St-Hyacinthe today. It's about three hours away.
On on my way back the P11D7 code recurred. Now for the third time... Incidentally when I stopped I noticed a vinegar odour.
Looks like I'll be bringing it in to the dealership once I'm back from Seoul.
Be careful with that. Sequential short operation time can cause a DPF full condition if your timing is wrong (i.e during the start of a regen). For me it was pulling into bay at tire shop, shutting off, pulling out of bay, shutting off.P11D7 code today
crossing fingers its the running the car for short amount of time thing....driving it up and down ramps yesterday and today for servicing
I have 141K miles on my diesel and have never had a problem with this sensor. i drive the car aggressively though and there are some theories that driving them hard keeps the sensors clean.Is there any recalls for the NOx Sensors on the diesels. I am seeing this same P11D7 alarm on my 2014. I have been into my dealership and all they have done is cleared it and said to keep an eye on it. I am currently under my extended warranty period and think I should have it replaced before it runs out. Any thoughts
