I have been having some problems with the VW Golf TDI PD150 being a little sluggish at lower revs. As the car has well over 200,000 miles on it I decided that it would be worth doing a
N75 Boost Pressure Control Valve replacement to see if it improved the situation - with that kind of mileage I figured the valve could benefit from replacement anyway.
The N75 boost pressure control valve is situated to the rear of the engine bay bolted to the bulkhead. There are two bolts that need to be released to remove the N75 valve.

Once the bolts are undone the N75 Boost Pressure Control Valve can be removed, the hoses uncoupled and the replacement fitted. Securing the replacement is the reverse procedure.

Once fitted the sluggish performance had not been resolved but the throttle response seemed much sharper and the acceleration more responsive. Next step is checking the vacuum lines for any leaks.
