Yellow CEL. Bogging on power.

[anonymous-user]

W205. C250d. 2016.
Limp mode today at a busy roundabout.
Power came back but then felt underpowered.
Checked Ad Blue. Display states cannot report level.
Good at keeping this topped up and haven’t really gone anywhere so don’t see why it would be low.

Don’t have a scan tool.

Any help appreciated.

NOx sensors?

There's a whole thread on that on MBClub uk

Yes. Went in today. Actually broke down outside passing by the dealership. NOx sensor. Will be covered under extended warranty. Part on order. Arriving Monday.

Thanks for update & well done for having an extended warranty - some of the prices on the MBclub thread were eye-watering.

Very sensible! I certainly wouldn’t want to own an MB - especially a diesel- made in the last decade without a full MB top-tier warranty.
