Anyone else had a recall letter re HTM Engine Management Software update for C3 Aircross. Luckily I have my car booked in 28 Sep for tyres so they can do it then. They need the car all day!

Yes I received letter today also.
It mentions something about issues with NOX levels when driving on low fuel.
I may be wrong but thought NOX levels were more related to Diesel engines and not petrol or does it affect both? Mines a petrol engine and have received letter.
I'm like you got mine booked in for its first MOT and service next month anyway so they should hopefully do it then, but have contacted them to make sure.

NOX is produced in petrol and diesel engines. Diesel produces more and has to have exraa mitigation. For most manufacturers that is the Adblue system.
