right the turbo i drove always had - pressure ie the neddle was always in the bottom white area even when the engine was off, but ive just wound this picture on the net of the guages and this one sits at 0 and its out the car, anyone got any ideas.

Funny at first I thought someone has been altering this set of clocks, but than, I saw it was a Rh drive version. ( the way the clocks are mount in order, a LHD has the turbo gauge in the end)

No. the arrow is ok like this. Its in atmospherical order. If you start the engine (re, connect one first) you get vacuum, so the arrow points totally to the left. If you throttle up, the tubo fights the vacuum and builds up over pressure. Depending on the pressure of the wastegate spring, it would't go furter than just before the red.

Its OK

luck

hold on i just thgouth see when the engine is off there would be no pressure so should the guage not read 0 (start of the yellow like in the pic). the one i was in was at -14 all the time untill on full throttle then it went up.

It should rest on the start of the yellow when the engine is off (0), drops to -14 when the engine is running, and goes up when you give it juice..
