I have had P11D7 quite a few times in my early ownership experience. One nox sensor was replaced - and the final fix was the discovery of bolts broken at the exhaust pipe to the SCR catalyst.

Dealer thought that ice broke them. But now we see many CTDs have the same fault.

Once those bolts were replaced I never had another check engine light. I'm currently at 49,000 miles.
