Hi Everyone,

I think my 940 is literally running no boost. It smokes a little on start but no other time so no tell tale failed turbo signs for such low performance.


That said, it is very dirty around the turbo area and caked.
So could the turbo be kaput but smoke free? It has years of grime on it to wash off.

Or are they really that slow standard and flat ? It does not feel boost assisted really. Acceleration increases at 3k but no noticeable kick at all or boost noise etc.

Should I run a t piece and test boost? What should it be if so?

The car has done 256k miles so far on standard everything major i suspect. Its got good service history but its soldiered on it seems beyond a water pump, thermostat and small bits.

The previous long term owner told me he had not cleaned the engine bay in 19 years and it shows

Also on the intercooler piping etc front and cooler itself, are they the same as petrol turbo units?

Thanks
Mick
