Faulty Turbo?

How'd you go?

couldn't get the unit case apart or off so i disconnected all cables and leads and blew them out with an air compressor then reconnected them, worked fine this morning but i'll bet money the problem resurfaces , the gauge is more prone to well..being a shithead at warmer temperatures. very annoying but i can't be bothered doing anymore than what i can at home.

are you at home @ 3:30 in the afternoons?

i usually finish work at 4:30, noticed the problem only occurs when the car is running hot, still investigating

I had a similar issue in my 34GTt.

Turns out (for me) one of the vac hoses was disconnected at one end (it had cracked at the end).

Snipped the end of the line, connected it back up, and good as gold. Ended up replacing that vac hose in the end just to be sure.
