1.6 L / 1.8 L / 2.0 L with 74, 75, 85, 92, and 110 kW.

The check engine light is illuminated due to detected misfires (error codes: 16684, 16685, 16686, 16687, 16688).

Cause:
The imbalance in the serpentine belt is transferred to the crankshaft and is detected by the engine control unit as a misfire.

Solution:
If the described fault is present, but no misfires are detected during driving, check whether there is excessive pulsating movement of the serpentine belt tensioner.

If so, the ribbed belt needs to be replaced. Since only ribbed belts from the company Gates are affected, ribbed belts from the company MBL can be ordered as an alternative.
