My friend has a GTT Caldina and last night driving along, we went to boost and it boost spluttered (kind of backfired out the gate) and the boost gauge was spiing up and down between 7-15 PSI (Currently tuned to 15PSI).
We then stopped and opened the bonnet- origanally thinking a boost hose or pipe had blown off, we had a hunt.. Couldnt find a thing..
Went to start it and it tunred over once. Then didnt even turn over again.
The starter motor makes and engaing noise when I turn the key, but its almost like it has seized or something!?! Any one got any ideas??
