I was just wanting to know what parts will & will not work on my car.

my code reader says "circuit no activity selected (bank 1, sensor 1) Can u explain please

I can't figure out the size of my front brakes an rotors.. Any help??

Replaced transmission and neutral safety switch

Replaced neutral safety switch, but does not register on the dash any gears. I put in neutral again and starts

I replaced the abs module and the abs light went away but its still flashing the brake light constantly, the brake fluid is full......

Only causes the battery light to go out...battery is good

just curious if my 1999 a4 is HID bulb compatabile or hallogen only.thanks in advance for any help given.

we just had 4 new tires put on and had the shop go ahead and do a 4 wheel alignment to prevent premature wear on a brand new set of tires!!unfortately they found that the uppr control arms were loose,to the point they couldnt correctly align the front end.i have heard some horror stories of a "frozen" or siezed bolt in the pinch bar part of the assembly,ANY hints,tips,advice to help me get through this smoothly will be very much appreciated..and i send thanks to all.

im almost certian the central lock pump is trashed(through research on this site)so i need any information on if and how i can open the trunk lid to access the part to know for sure,i cant find any button in the dash pocket and after dropping the back seats and crawling around i can find no release cable inside the trunk itself.any information on a way to get to the pump will be greatly appreciated.

the central locking pump prevents the trunk from opening so how can i access this part for replacement
