Might as well do an update.

Solved the problem as of 3 weeks ago.

Found the rear mount was leaking (front already replace), TCV was changed, Boost pressure sensor changed and a replacement turbo.

All vac tested and smoke tested again, no problems visible and no codes.

Car is now quieter, averaging 2 mpg more on my 10 mile commute.

So hopefully that is that.

Lesson learnt: On a car thats 13 years old, change the lot, dont mess around with bits here and there. You may save a few pennies in the short term but its all going to need changing at that age.

Hi so if it was the mount that was bad,
why did you get a new turbo,tcv,map sensor, why did you not test it, it would have saved a lot of cash,

Simple answer to that my friend,

The turbo was sooted up where it would occasionally stick causing overboost. And no I was not going to go to the trouble of stripping and cleaning and the potential of have something else go wrong with it.

It also had the seals on the cold side leaking a little oil into the intake.

The TCV was marginal, in that it was not operating properly from time to time and the boost pressure sensor was just a matter of course.

So everything really needed some maintenance/replacement.

The rear mount was not leaking last year, but this year it was.

I had to take the decision to throw in the towel and get another car or dump some cash at it (for a lot less than a second hand car) and run it another couple of years.

So thats what I did.

Like I said, it runs smoother, it has less noise and better mpg and no recurring limp mode.

good that it is all sorted now,
my vacuum mounts have not got yet, but mine is an 2002 so I will keep my fingers crossed,
on a turbo car there will always be some oil in the intake pipes, but not bad, and that is where Volvo put the oil breather pipe,
