Yes will do. Although it doesn't seem a common problem. When people do experience this issue from what I have read it results in large garage bills without the problem been resolved. It would point to this as mine also runs ok without the air meter been plugged in. Thanks again

Thanks Alan. Maybe some confusion on my part, from what I have read the map sensor and boost sensor are the same thing some people just call them different names. I have already replaced the MAF sensor (well it's had three genuine ones actually to make sure there not faulty) Will get a boost...

Hi. Sorry to dig up an old thread but I have exactly the same problems with mine ATM. And the garage has now run out of ideas. How would I go about changing the map sensor or boost pressure sensor? Is it a fairly easy job? Thanks Dave
