Hello just after picking peoples brains... the engine warning light came on the other month and highlighted a couple of issues...

The first was for a secondary air flow sensor, ... I had a look and the the hose looked warn and damaged, I have since removed and replaced the hose and deleted the fault in the ecu memory...it ran fine for around 2k and then faulted again.

However on the second time of failing I now have a fault in the ecu memory, which states the the throttle body is loosing pressure.

Anyone got any ideas ?

Thanks

D.v.

I take it you mean the dump valve ?

Just a thought, I have just had the cam and waterpumps replaced etc approx 800 miles ago, could an incorrect set up be causing me these problems ?
