The wastegate is pre-DPF and SCR, so that's pretty typical of how it looks.
Which raises the question, why isn't the EGR post-DPF?The wastegate is pre-DPF and SCR, so that's pretty typical of how it looks.
'17 CTD 7k mi. Today I went in for my first oil change and the technician noticed an exhaust leak at the waste gate near the turbo. It's small enough it can't be heard, but big enough it's spewing soot everywhere. Pics below. Obviously it's still under warrantee so the plan is to drop it off next Saturday and drive a loaner until it's fixed.
My only real question is, why is there so much soot in my exhaust that a small leak sprays it all over? I expected cleaner exhaust. What must the inside of the manifold and turbo look like?
They didn't make a 16 diesel. Your dealer sounds like idiots to me. Who drains oil and doesn't have the proper filter prior to draining? I would find another dealer.I dropped my car off on Saturday. First they told me this was completely normal, because "diesels are dirty". They reassured me that everything seems to be operating within nominal ranges, so the car runs fine. No surprise there. When I expressed surprise that a brand new car would be designed such that the under hood area doesn't stay clean, they changed their mind and decided to send my case in to GM engineering tech support. My car stayed with them through Wednesday with no word back from GM. We decided I'd pick up my car and continue to drive it while my case makes its way through the process. Nothing yet. The foreman told me he'd email me whatever info he gets back, and I'll post what I get here.
The foreman told me they happen to have a '16 2.0L in while mine was in and he looked at that one for comparison. While the turbo is oriented different so it's harder to see, he said he observed the same soot and dribble on that '16 as is on my '17.
I will at least give them credit that everyone has been very courteous and helpful through the whole process, from the quick lube tech that noticed it, to the service personnel, and the shop foreman. Mostly I'm chalking this up to being an early adopter of brand new engine. Did I mention that when I went for my first oil change, they had to change it twice because they discovered they didn't have my filter in stock after they drained it? Had to go back a week later to get the filter changed.
Somebody who's trying to work efficiently. And somebody who assumes everybody else in the dealership (parts manager) is doing their job efficiently too.Who drains the oil before they have a filter? Someone who's never not had a filter. It seemed to really catch them off guard. Like it happens super rarely.
...just not continuously. (unless there were still new 2015s on the lots when the 2017s came out, which is entirely possible)Diesel has been available in North America since the 2014 model year.
