Idle speed boost

WARNING: This page is about a different car, the 1996 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.

Pulling the Cold Start Accelerator cable to the first stage increases engine speed by approx. 60 RPM.
When the cable is pulled out to its maximum, engine speed must rise to 1050 50 RPM.

NOTE: The manufacturer's basic setting for the diesel injection pump ensures that idle speed can normally be adjusted as described, and that the higher idle speed specified above can be reached by pulling out the Cold Start Accelerator cable. If the idle speed cannot be adjusted as described, carry out the basic adjustment. See IDLE SPEED, IDLE SPEED BOOST, MAXIMUM ENGINE SPEED (RPM) AND RESIDUAL FUEL DELIVERY, CHECKING AND ADJUSTING .
