Me and majority of other gen 1&2 TSI owners with carbon deposite issue mostly stuck in traffic driving at low speed 5 days a week and run short trip to store during weekend. The road condition do not allow us to drive like the way you do like you mention previously during rush hour which is 90% of the time we use the vehicle for. If you believe it is not an issue that is fine. But I feel the obligation to let others know that this is an issue that exist. Milage and years of use till causing misfire will very just like this case. But it will happen eventually. VW did not list carbon cleaning as a maintenance item. Instead this is considered as a repair item back in 2014 when I talk to the vw dealer. And at this point I dont really know why we are talking so much about this but not the timming chain tensioner which cause complete engine failure. And I know you may say hey my CC went 90k with no issue, that is fine too. Since I already know there are quite alot incidences on timing chain tensioner issue for 09-13 model year TSI engine I feel no benifit to withold the information I already know on these engines from Gen 1&2 TSI owner I come across.
If you are happy with your 11 Tiguan good for you and good luck. Maybe keep driving it for years to come without doing carbon cleaning or timing chain tensioner update VW will buy the car from you to present a case to defend themself on the class action in court which filed by hundreds if not thousands of consumers that stranded of an engine that cost a fortune to repair all because it was a design flaw.
First of all, I would say I am much more familiar with these issues then you. So I feel obligated (to use your lingo) to tell you that VW does not build cars or engine for some guy in Houston, TX. They sell it there, but their priority is guy in Frankfurt and Munich, not Houston. So they design engines with that in mind, not Houston traffic, drive thru and 24oz cup holders.
So if you spend 90% of your time in traffic, why VW? Why not Toyota Prius? Why not RAV4 hybrid? You want CUV with autobahn characteristics to spend 90% of time in traffic? Sorry mate, but it is not VW's fault.
I buy cars that fit my life style. I am skiing twice a week (200mls round trip), I will next month go to Chicago. Wife has conference, then me few days after, pack kid in the car, Yakima on the roof, and fire up BMW oil burner. Probably up to 3000 mls. In June, Colo. Springs-Vgeas-San Diego and back. Tiguan? Every time we go to Denver or some other CO destinations together where we do not need so much trunk space, we hit it with Tiguan, and trust me, sees more redline then 2k rpms. I change oil every 5k, I use ONLY oils that meet with VW 502.00 also MB 229.5 and do not use that dealership POS Cstrol 5W40 that VW uses. Same thing was with CC. Was driving that car skiing since it was more useful to fit skis, had winter tires, and just blast on CO local roads with it, at 96K was running equally strong as at 24K when I got it, not using drop of oil, which was ALSO one of the complaints about TSI engines (Tiguan does not use drop of oil too).
Issues you are mentioning are so rare in Europe, precisely because of driving patterns, oil in use etc. So drive it like it was meant to be driven.
So maybe I develop problem with Tiguan, maybe not, but do not assume just because you had a problem or some other people on forums (people come to forums to complain not to say: oh I am opening thread to share how reliable my car is) does not mean everyone else has that issue. Every DI engine has issues with CBU, it is question how much and what you do to mitigate that issue.
