Right im new to this so sorry and will say thanks now for the help (i hope). Right driving along dual carriageway red engine management light came on call rac he said its
DTC: P2002,Particle filter
DTC: P0544,Turbine upstream temperature sensor circuit
DTC: P1525,Consistent multiplex signals for cruise control/speed limiter
So my mpg is shot 450 miles to a tank no other noticeable ptoblems apart from cruse control dont work searched everything main problem is p0544 live date said that there is no data being read from sensor. and other 2 are knock on effects so my question is what is p0544 why is this happening quoted over £300 from nissan :lol: yh ok its a 2011 nissan qashqai 1.5dci ntec j10

Certainly no expert nor mechanically minded, but putting two and two together it possibly suggests imminent dpf issues. Have you experienced restricted rev limit and slow acceleration (known as limp mode)? If it is a regen issue then this will need to be done at a garage.

No limp mode and more power if anything no stuters at all jist terrible mpg and no cruise control i have followed a green wire which goes to a probe i unplugged drove the car to see if theres any more faults but nothing i remembered doing this on spark plugs for a miss fire would this work the same for a bad sensor?

You need to visit a dealer or independent with good diagnostics capability.

Right update for future people who come across this post and need it. Engine temp sensor on manifold changed. dpf regen. oil and filter changed. pick up tomo also there was a ecu regen on this car too hope this helps as i have had 4 diagnostics and the last 1 has fixed it cruise control problem was a knock on effect. if eml lights on this wont work. £360 now time for my mot. :s
