hi would this solenoid effect the acceleration? i have a problem with hard acceleration uphill the car pauses for a few seconds (like its taking a breath) then goes again, it does it at 2100 and 3000ish rpm weather its hot or cold i notice it more on a cold start.
thanks in advance

Yes it could, although your symptoms sound more like a dirty EGR, as that will cause a lag at high revs. If it blocks it can result in a rough idle, but lag during acceleration seems to be the first symptom.

I cleaned the front pipes a few months back they didn't look too bad ill remove the whole thing a give it a good clean..... hopefully its a cheap fix

Ideally, you want diagnostics on it but at the very least, you want to test the VNT mechanism and actuator range of travel with a vacuum tester.

turbo pipes have been checked and the turbo itself has been rebuilt and flow tested with a new actuator. it feels really strong when accelerating until i hit these flat spots. I have the basic diagnostic you recommended and the icar soft diagnostic shows no faults.

Has it worked perfectly at all since the turbo was fitted?
