One of the locals at my pub was asking me about a problem with his car (Zafira diesel turbo) Having trouble with the turbo, felt like it had very little boost compared to what it used to.
I said at a random guess it would be the actuator.

Turns out, it was the actuator needed replacing. So the local vauxhall dealership did the work and handed him the bill for £970!

That seems a bit steep to me? or is it like an engine out job or something?
