Have a 2002 GTTDI 130
Goes like a rocket, no turbo lag etc.
Fuel consumption is not good, 42ish at best, my Passat Est 110 can do 60mpg
The braking is severe, you cannot slow at a junction gracefully, the brakes only need the lightest of touches to come on. Have stripped and cleaned the brakes,but no change.
Ref the fueling/performance have checked the turbo for movement of actuator,seems OK, changed a suspect rubber seal on the main air pipe after the turbo, this to try and prevent any overboost/fueling as maf would see all air going to turbo, and turbo could be overboosting due to air leak on downstream side, then the ecu could over fuel, hence my rocket acceleration/performance and poor economy (my theory)
Is there a common thread between brakes, vacuum, n75 valve etc that is causing these probs? Have driven an Audi 130 and this car will eat it, but I'm not looking for performance, just a normal 130 with good economy and sensible brakes.
The car definately hasn't had the ecu chipped as ECU map checked by garage, and there are no visible add on devices plugged into maf or water temp sensors. Car only went into limp mode once I think, as I wasn't the driver, due to overboost which was on the memory (detected and removed by garage), when restarted was OK and still is.
Car has been serviced, doesn,t blow any smoke out, drives very well in all other respects. Have just put come redex into fuel, but on this last motorway journey at 80ish the consumption was still 42 mpg
Have read through all the threads on Turbo, Actuators, n75 etc and all seem to be associated with loss of performance, I,ve got too much! and too much braking efficiency....whats the link?
