MattmanS8

Hi, Recently got my 2002 Audi S8 360bhp and the CEL is coming on. The 2 codes it's giving off are P0492+P0491; from what I read these codes are quite infamous when it comes to the 4.2s. I've read a lot of threads on the problem and many of them suggest checking a fuse or the relay. I'm not really sure where the fuse on the S8 is located. It's in the footwell on the right side of the car on US models but I've opened this on mine and it doesn't look like a fuse is supposed to go there. If anyone has had the some problem I'd love to hear some suggestions. The car doesn't make any unusual noises on cold start and the car runs just fine.

Another little niggle with the car is the parking sensors turn on but it just beeps like there is something right in front of the sensor. You turn them on and there is just a long high pitched beep and then it goes away. I've gone around the car and I'm able to hear each sensor clicking so it would seem like they are all working fine. Again, anyone with experience with this; I'm all ears.

Thanks for the help.
