UK Car Repair Questions? Ask a Mechanic for Answers ASAP
Hi I'm Kevin I will try and help you .so just to clarify which sensors you are unplugging to give improvement?
Ok the code is referring to a air pressure coherence problem so the air pressure in manifold that is being measured is not what the car is expecting to see the most likely cause is either map sensor or maf sensor
There are a few options other than that but it sounds as though you have already covered them
blocked air filter
how long has egr been blocked I'm assuming not a recent thing ?
That's what I though let me know how you get on
I still suspect a maf fault it fits with the code as it's showing a difference in air pressure
No worries let me know how you get on
That is very strange you got me stumped no I will opt out this will add question back to list to see if another expert can assist I'm sorry I couldn't help more
