We had a T4 in that was under powered and smoked a fair bit, typically with these olds vans there are no faults shown so we attempted to catalog it only for what was a knackered turbo to totally let go. This will be back in for a turbo shortly. Before we go, this had been tampered with, there was tape all over the actuator and it appears that its as wound right up then back down again. Doh.
