Re: b5 s4 fault codes help?

try and clear the brakes in the ABS/brakes part on vagcom

its your sensors in the pads. if you bought pads with no sensors you have to put a wire through the middle connector on the harness to loop it so it shuts up already

if your trunk is leaking its actually vacuum locked.. there is a black hose on the right side for the popper take a peek at that

Re: b5 s4 fault codes help?

Luckily it's your pass. side EGT that needs to be replaced, which is the easier side to work on.

Re: b5 s4 fault codes help?

would the egt explain why my gas milage sucks balls! i have OEM brakes with the sensors and it never went away, i guess i will try it again. as for my trunk it is coming from the passenger side.

thanks guys.

Re: b5 s4 fault codes help?

Yessir, bad EGT=bad fuel mileage.

Try checking the connection at the pad wear sensor connector.

You have one of each, one goes to the passenger side, one to the drivers side

Re: b5 s4 fault codes help?

I think he's actually got 2 black EGT sensors, depending on when his car was made, exactly. The early S4's came with 2 black sensors and the later ones came with a red and a black one. The good news is that it's extremely easy to pop your hood and make sure

Re: b5 s4 fault codes help?

yea no lies man.. the new o2s were awesome.. i do need to change my plugs too.. 6000k on the bkre 6's on a 2+.. i change them every oil change

Re: b5 s4 fault codes help?

well i definetly have some work ahead of me, im hoping to do my egts before i come down to calgary and see jordan for a tune. o2's are a must as they have been an issue for the past year, if you tune them out will it cause poor gas milage? or is it better to keep them
