1998 Jetta TDI - Fault Code P1248: Cold Start Injector Control Difference

Model: 1998 Jetta TDI Fault Code: P1248 Posted: 2007-09-20 18:45

My 1998 Jetta TDI diesel engine won't start, and the only fault code detected is P1248. I'm concerned whether this code could be directly related to the starting issue. What does P1248 mean exactly? And what steps should I take to diagnose and fix it?

P1248 refers to a 'Start of Cold Start Injector Control Difference' — this indicates a discrepancy in the control signal for the cold start injector. This could affect fuel delivery during startup, especially in colder conditions or if the system is not properly calibrated.

Check if the timing belt has slipped or is damaged. Also verify fuel pressure — a lack of fuel pressure may prevent starting even with P1248 present. Additionally, ensure no fuses have blown, particularly those related to the fuel injection system or engine control module.
