I posted a few weeks asking on buying advice regarding a 2011 and a 2015 E class.

I also asked on a UK Mercedes forum and pretty much every reply they were warning me off buying anything Blutec from Mercedes, told me to stick with the earlier BlueEfficiency stuff.
Main problems they quoted were NOX sensors failing, around £300 each but that's normally followed by the Blutec pump failing which can be up to £2,000 to replace etc etc.

Surely, that many taxi drivers can't be wrong. There are thousands of them using the E220's of the vintage I'm looking at. Appreciate that I've asked on an owner specific forum so I probably will get more negative responses, so I'm asking for people’s experiences of the system on here.

Is it really that bad?

Car in question is a 2014 E220cdi sport with 40k miles and full MB service history.
