2004 Volkswagen Jetta GLS 4 Cyl 2.00L
The check engine light came on and when i took it for diagnosis it came out as "check colling system"
The milage when i got it was 112,243 and the check engine light came on about a week after i got it and after diagnosis i was charged $900 which i find unbeleivable.
Do you have the stored trouble code (example P0XXX)? If you have can you please post the extracted trouble code?
