The fuel-air mixture is further enriched via the warm-up control after start and post-start enrichment. The warm-up control compensates for the fuel which precipitates on the still cold engine parts.

An additional quantity of fuel is added to the engine by the ME control unit in line with the performance map. The injection time is extended accordingly for this purpose.

The warm-up control is dependent on:

• Coolant temperature
• Intake air temperature
• Engine speed
• Engine load
• Correction programming with STAR DIAGNOSIS
