Finally had a response from Mercedes. They are now changing both NOx sensors, free of charge. They will do the work today and then run lots of tests tomorrow and extract data to send back to MB in Germany to ensure it is actually fixed. Once all of that is done, I will discuss with them whether...

Have heard from the dealership today. MB HQ have responded twice to them asking for more data. The dealership suggested that it is good news that they have been so quick in responding (within hour/s). Not sure that is such a good sign to me.....

Just spoke with the dealership. They had to send off a load of data to MB HQ as they couldn’t work out what it was telling them. Something to do with data from the NOx sensors. MB HQ got back to them and asked for some specific data/information which they provided immediately. Hopefully should...

Many thanks for this, Jigglyjohnson. Will certainly raise this with the dealer and ask for prinouts of all fault codes via email. I would not be surprised if the NOx sensor, temp sensor and AdBlue pump were all due to something along the lines of the above. If so, I am doubtful that I will be...

Yes - the warranty ran out some time ago and didn’t think that it would be worth having one (how wrong we were). Assumed that a fairly mass produced, premium car that is not performance/does not have high stress components would not cost so much! Have returned to the dealership partly as hoping...

Unfortunately not— didn’t think that it would be something we would need to do! Will the ‘star’ system, or whatever they call it, not have a log of everything done on the car, including fault codes raised by diagnostic?

Forgot to mention, in late Jan it went in for it’s major service and nothing came up.

Morning all, We have been having ongoing issues with my wife’s w205 c250d. Annoyingly, we did not initially have a warranty so it has cost us a fair bit! It is a Jan 2015 car with 65k on it, so did not expect it to cost so much in repairs. We are only 2nd owners (bought it at 3 years old from...

Unfortunately didn’t get that advice off the forum prior and the independent said that the dealer wouldn’t touch it. Wasn’t aware of them being covered by warranty at the time. Well aware now (NOx sensor, temp sensor and £1000 later!). Mercedes assist have just been out. Looks like the...

Update: Independent had done software updates etc. Exhaust Temperature sensor had gone. Had that repaired. Subsequently the adblue warning came on and started countdown. Have topped it up but thecheck engine light and adblue countdown remains. also interesting to note that the last service in...

Really struggling to know what is best to do here! Feel like I should have taken it to main dealer for NOx initially to see if they would contribute. Now not sure whether to crack on with independent garage or take it to Merc. Guess I can get the independent place to diagnose and go from there?

Update: Engine light has not come back on, but the car went massively down on power after a motorway run today. Any ideas? Is there a way to see how full the adblue is? Wondering if it could be something to do with this and it’s not come up with the warning saying it’s low!? At least hopeful...

I’ve used Merc Medic bear Ripley recently. Seem pretty good. Keen to look at PCS for next work!

Morning all, My wife’s 2015 C250d recently needed a NOx sensor. Really annoying and expensive issue given that the car is only just over 5 years old! It has subsequently thrown a check ending light that came up as a temperature sensor and inefficient catalytic converters. Just wanted to see if...
