I have a problem with the car going into limp mode, and the engine management light coming on (occasionally). The code reader shows 2263 (turbo boost issue).
I have replaced the stainless steel pipe to the EGR valve, had the valve cleaned out and I have now blanked it off.
I start the car in the mornings, and the car runs perfect, no juddering, loss of power, or anything. I stop the car for less than 2 hours and I get the dreaded limp mode. If I leave the car for more than around 3 hours, now problem on starting and driving.
I have read on posts that a turbo hose could be leaking, although I can't see that as I have no loss of power at all.
I have read that the MAS sensor could need cleaning.
I have also seen that there is a vacuum thing between the MAS and the EGR valve, I assume it is a boost sensor valve as it has three pipes going into it. between the EGR valve, the turbo actuator and some where else?
Can anyone give me any tips on how to resolve this problem, very frustrating as I thought I had cured this by blanking off the EGR valve. The car ran perfectly for 4 days without limp mode, which made me think it was all sorted?
Thanks in advance for your help xxxx
You wont feel a massive drop in performance on the car if you have a split pipe or hose. I would be starting the engine and getting someone to give it a few revs whilst feeling around the intercooler pipe for any leaking air.
