E350D NOX Sensor

[GeoffCapes]

So a few weeks ago the engine management light came on in my car. I took it to the garage who I have used for years with various cars, and they plugged it in to their iPad thingy and it diagnosed a faulty NOX sensor.

With Brexit and whatever else there was a delay in when the parts would be delivered (to the local MB dealer). And they had no idea when that would be.

I get a phone call on Wednesday that the sensor would be delivered on Monday (yesterday) and to bring my car in today.

However, with the storm on Friday, it ripped the roof off the garage I use and the garage is currently closed (for obvious reasons).

However (again) I drove the car 160 miles on Saturday and the engine management light has now disappeared from the dash.


My question is this. Has my car done what my Italian cars have done and fixed itself? or will the fault return at some point?
The reason I ask is that I had to stump up £561 for the sensor from MB and if I don't have to use it, I'd like to get my money back!

I think with the NoX issues that I hear, I’d keep the sensor to hand for when it is needed as it seems its a matter of when, not if.

I'd be surprised if MB would take it back. Dealers of all flavours don't normally accept electrical stuff back unless there's a fault with it .... Citroen would lt me return a heater blower resistor.

From my experience if a dealer orders a part in specially they are very reluctant to a return unless it’s a faulty item

Is it worth just getting them to fit it then? (I imagine it's not a big job to do so).

We not get ANY returns on electrical components
we do not get ANY returns on orders under £250 regardless of type
we do not get ANY returns on anything special ordered (And often do not get an ETA on Backordered parts until we special order, nice that!)
We DID get a little Bluetooth speaker last Christmas that says "StarParts" on it though
