Hello,
i have Audi A3, 1.6, 1998.
when the car is cold, goes normally. When he gets to 90 degrees Celsius, it loses power and engine not running at full power. We have already changed CKP sensor, lambda sonda,air filter,sparking plugs.. problem is still here..diagnostic says error 00513. does anybody have solution for this problem? sorry for bad english

 

Ross tech and google shows 00513 is the following error:
*Engine speed sensor (G28)

possible effects:
*Engine does not start
*Misfiring
*Engine cuts out
*Engine does not start


Check your speed sensor and wiring.

 

Engine speed sensor is CKP sensor,i've changed it..

 

Did you clear the code once changed? If you did and it came back - check the wiring.
