As in title
Any help much appreciated and will keep me going for a few more years with any luck
Cheers

Most likely to do with the solenoids and pipework on the bulkhead the turbo control one will be tired.

So, it souunds like there's a weird noise coming from the solenoid area
Is there anyway of checking the solenoid?

You will have 2 or 3 depending on age 1 is turbo 1 is egr and 1 is dozer flap if it has 1

Swap the dozer flap 1 with the turbo 1 its easy enough to figure out just follow the vac pipes.

If that does not help you need to check for stable vacuum.
