Hi
Yeah I sent an email see what they say. I was surprised at the crappy customer service experience I got from them. Couldn’t go toilet no drink I can understand due to COVID but atleast keep checking on your customers I waited over an hour and no one came to see if I was doing ok and after the diagnosis no one went and showed where they parked my car I had to find it. They even spelt my name wrong on the invoice how can they do that when I gave them correct name on email
Hi, hope I’m not too late and you’ve not had the work done. I discovered I had an issue with my 2015 W205 NOx sensor, getting the same P2200 fault code. I searched everywhere for aftermarket parts but realised a new sensor would need to be calibrated so a dealer would have to do it. Anyway, contacted a local independent who didn’t get back to me, took it to an approved Mercedes center at the bottom of my road. They said sensor needed replacing and wanted £650, they said they spoke to Mercedes main dealer (literally next door) and they refused to do it for free due to the age of the car. I told them to leave it. That evening the independent garage called me (he’d been off with covid), said he wasn’t able to do the NOx sensor as Mercedes didn’t sell the new part to independents BUT that he knew there had been a service recall issued for that part. Not a full recall where they have to write to you, but a service recall so if your car is in the dealership they should fix for free regardless of age / warranty. He told me he had many clients who had this issue and Mercedes had fixed it for free, he even gave me details of someone with the same age car (with owners permission) that I could quote as an example of them doing it for other customers for free.
I knew I had an outstanding full recall on my car (for an airbag issue) so booked it into the main dealer and asked them to also look at the NOx sensor issue and told them I knew it was part of a service recall...
Anyway, went in today, all work done, sensor issue turned out to just be a software update that was required (but he implied he would have changed the sensor if needed). Did it all free of charge and a full health check. (2015 car, never serviced at main dealer)
so basically - worth checking if you have any full recalls outstanding (should be able to search online) and then ask them to check the sensor at the same time. Alternately just tell them confidently that you know it’s part of a service recall and therefore expect them to fix for free.
anyway, hope that helps. I won’t be going back to the approved garage again but I will be using the new independent who was incredible helpful. Fair play to the main dealership too who were great.
