A couple months ago i put a cold air intake on my 99 audi a4 and everything was good and yesterday i had my s-belt my t-belt and water pump replaced and now i have a code saying something to the effect of speed control auxilairy input error. Can someone please help? Thanks

 

Do you have the exact fault code? We can't help you unless you do.

 

my error code is p1522 thanks

 

P1255
Engine Coolant Temp.Circ Short to Ground this is the explanation for the code..Does this mean i need to get a sensor or something? Please help thanks

Probably. Those sensors are notorious for going bad. You could check for a short in the wiring but i would just replace the sensor.
