You could turn it down to standard boost pressure. Just to see if it cures your problem, there should be a solenoid in its place.

Solenoid in its place or reconnect pipes ?

If I'm reconnecting pipes does that mean I need new ones? It looks like they have been cut.

i need better pics mate , to see how its fitted , cheap e bay controllers just require you disconecting vac hoses from turbo and putting them on man boost controller which bleeds of to atmos leaving any solinoids unused on inner wing / sorry for my spelling just got in from work , and knackered!

Today I've removed it after studying the pipes and further research online I've figured out how it should go. But still have an overboost do u think I need my ECU reset or even try cleaning the pipe work may help.

The link below is what I followed.

How much over boost are we talking??
You could clean the solenoid and pipe work out, search for the procedure on here,
Have you adjusted the bleed valve ? It may have been fitted to stop an overboost problem!
Is the pill in the pipe still?
Is your car mapped? I'm thinking not as I'm not sure any mappers would advise to fit a bleed valve. You could use the bleed valve to set standard boost pressure, and use it to 'cap' the boost. If the valve is working you should never get an overboost issue. You may have a faulty boost solenoid hence why the bleed valve was fitted.

And yes an ecu reset would help. It should be done after any replacement of engine management

The valve has been removed now.

The car over boosts after about 3000 revs in all gears, only when you accelerate hard.

The Pill is still in and the car had a remap in 2008 this valve was fitted by the previous owner pointless with a remap really that's why I wanted it out.

How can I reset the ecu myself?

Make model and year? 2001 bug is it? From your last thread
If you don't have access via a laptop and cable, yank the battery off for 10 mins should do it.
