First things first bud.Hi,Im well chuffed I got vaggies(VAG enthusiasts)I can chat to and not troubleshooting mechanic rookies!
1.-its plugged into airbox sensor and one in fuel sensor.
2.Never changed sensor
3.-high temp stat was a 95c one(I think)
4.not sure if I tested present one/might of
When I changed thermo/the stat showed 90c and the car DIS gave me 25%less fuel and 0miles is absolute.Same thing happened when I blanked top of radiator.Both times I converted car back to normal setup.on next fill of 20L,the ecu/DIS resets itself with new distance calculation and admitingly I think I got 25% more the second time.Thus there wasn't a problem in the first place.
This woulve happened with or without the box-positive on that.
So,back to square 1.
They say don't fix what aint broken.
So,every time the engine gets hotter than 70c the DIS ****s itself.Maybe I should run it two fillup of 20L to get a better average.
85c sounds right for a indicated 90c on the dash. If your temp sensor is failing, it will effect mpg. Honestly though, lose the tuning box till you can get a decent digital one.hi BLACKQUAT,
My bad.ive got a tdi tuning box which comes with two connectors.one for the fuel pressure and one for the airbox.its a pd engine as well.
Ok,so research says ive nothing to lose by changing the temp sensor.would this improve my mpg?
As well,my heat in the car don't get super hot,but when I blank or change thermo,its burning hot.mpg swallowed.
why would they install a 75c thermo.is this possible.i have the awx engine,and some say the highest temp spec is >85c.
so many questions now.
