CLS 400 Back To The Dealers After 3 Weeks

[Lapchien]

Bought a new CLS400 and 3 weeks later the engine management light comes on. So I call in at the dealers, thinking it's going to be a quick wait while you reset the fault code.

It turns out that I needed a new NOX sensor, and the technician said that the wiring loom was trapped and not installed correctly at the factory!

I'm not happy and wondering if it's worth moaning to MB?

I'd ask the dealership (politely) if there is any goodwill for the inconvenience first.
