Wow, I don't think anybody has ever had quite that many issues with their CTD. My track record over 202K miles paints a much different picture. I can't help but wonder about how the car was treated to have so many major problems.
That was actually a very nice write up with very detailed good pics to support why he was having such issues. That's a lot of soot and a lot of problems. If I had that many issues a delete might be a more serious consideration. I really wonder what may be causing all those issues and what appears to be an extreme amount of soot buildup?

or one can wonder how your car was treated to have the success you had.

see how that works?

I don't know what it is, but that downpipe looks adorably tiny...Any idea the diameter of it? Also, I'm assuming it is not stainless?

Great writeup, though. Where is all that soot in the intake tract coming from? Does the EGR dump forward of the throttle valve or something? I'm used to the EGR just dumping in after all that - usually internally in the head, or from the head directly into the intake (on carb cars).

The down pipe is 2 inches and is ceramic coated. The old pipes were painted with high temp paint but some people were not happy so it was changed to a ceramic coating.

202k miles in 3 years is all highway which has been known to be friendlier to emissions. Your car lives on the highway. Your case is not an accurate depiction of how the emissions system should act to the average person. Besides, I don't know how you would "treat" the car to cause that many emissions failures. How does the owner cause def injectors to melt, 7 nox sensors to die, and the dpf filter to literally explode, and basically every other sensor involved with the emissions system to be replaced at least once. Emissions failures on these cars are not the owner's fault. It's a crap system.

All right, good that it's ceramic coated. 2" is a bit on the small side, especially given the exhaust is 2.5".
I think the emission system may have many causes for failure. How one treats the system seems to be important, early on folks were over filling the oil, using the wrong spec of oil, etc. wouldn't matter if it is highway driven or city driven if the wrong oil and or too much is in the ctd. So this example in this thread, we don't know what the root cause of the failures are. I can't say I love the emission issues on the car, but knock on wood, I know the correct oil and amounts have been used and I have a nice mix of in town and highway driving and I have had no problems in over 26k miles. The example here could be a bad emission system and it could be as I stated earlier poor maintenance or lack of....the truth is we have no way to know.

There are two sides to every story. :)

By the way, my car saw plenty of low speed, cold temp, short trips, high traffic, lots of idling. The people who like to bash the emissions systems on these cars tend to conveniently forget that.

I think the bigger issue is, the car was at the dealer getting worked on by who knows.... half the time they cant even change the oil correctly on a diesel.. and it looks like several dealerships... best quote 'and the response from the technician was "I didn't even know Chevy put a diesel into a Cruze" ... Great. '
Wonder how many people still do the 1 qt of ATF per tank of fuel yet?
Old wives tail to "help" lube the top end.

BTW, 50K in 2 yrs, mixed driving with only two ghost codes that cleared themselves.
Spent two winters in N.E. Ohio as well.

BUT, there are lemons out there where the stars just align in the wrong direction.
Gross. Now I'm inspired to pull my intake and throttle valve apart and clean them out.

2 Stroke oil works better :)

I guess mine is one of the lemons. It's been back to the dealership 18 times since new with only 27,xxx miles on it. 90% of my driving is interstate. I have a 100 mile round trip commute, 26 miles of that is a four lane divided highway, lowest speed of 40mph.

The people who "bash" the emissions system have had multiple emissions system failures on their cars. When my def heater fails, I'll be sure to remember about your car and how it is problem free. It'll make me feel all warm and fuzzy as I leave my car at the dealership for repairs again lol :not_worthy:

All sarcasm aside, the only way these problems will get addressed is if they are communicated. You can call it bashing, not everyone has had the same experience as you and it's mostly because you have done a massive amount of miles in a short amount of time. I love the car and that's why I'm perfectly fine pointing out it's obvious problems. Because it is still not enough to make me get rid of the car or hate it, but the emissions system for many people is an obvious problem. Call it bashing if you want, it is what it is.

That should qualify for lemon status. Have you tried to get a buyback?

There's a line between reporting facts and bashing. I created the "common problems" thread, and had many of them happen on my car. My car has not been trouble free, by any stretch, and I clearly acknowledge the flaws.

I am referring to people who just jump on the bandwagon and flat out say "These emissions systems are CRAP blah blah, let's all jump on the delete bandwagon because they are CRAP...."

Yes, some cars have problems, but I've stated before many of the problems are exacerbated due to incompetent or untrained mechanics at Chevy dealers. There are a lot more reasons that some cars have more problems than others, other than "These emissions systems are CRAP"

Sometimes even, an owner just happens to be unlucky. No matter what they buy, it breaks, haha.
