My econ light would not go out the other day. Took it to garage and got system emptied/refilled and all ok. They gave me a print out of what they took out and what they put back in.

did u take it to a dealer?

No just a local garage. My local specalist wanted to charge me to put on diagnostic machine before fixing. The garage I took it to charged me the same to refill and would put on dianostic machine free if this did not work.

Sounds like the pressure sensor quite a common fault but you need a diagnostic scan to confirm this.

thanks matta4 does it have to be vag.com or vcds or will an snap on diaognostic show up the fault?

[matta4]

A snap on one should do we have a snap on solus pro 0n 9.2 software that we use now and again and its quite good on vag but not as good as vag com but should have no problem pulling the code and looking at the signal from the sensor

had the car scanned by a friend the code is 00819 / g 65 is it worth jus changing the high pressure sensor?

[matta4]

I would suspect the sensor but take a look here http://wiki.ross-tech.com/index.php/00819 this will help you sort it

thanks for all ur help matta4 kwik told me it took a charge so hopefully its either wiring or the sensor itself i may get the pressure tested again ive read a few bad things about kwik fit at least i didnt have to pay them
