Ds4 crossover engine management light came on. Read fault with scanner. Code p2202. Nox sensor. Fault cleared and has not cane back on as yet. If the sensor was fooked would the eml come back on right away.
One for the mechanics
- Thread starter IANB
- Start date
My experience with nox sensors is the fault can be intermittent so the eml wont necessarily come back.
Hope not mate £295 for a sensor
Id be making sure the wiring to the sensor is good before dreaming of parting with that money on it.
Yes it’s my lads car he is going to check that mate
