The sensor pulses (4 per compressor revolution) and the engine speed enable the Front A/C Display Control Head -E87- or the Climatronic Control Module -J255- to calculate belt slip.

If the belt slip exceeds a specified value, the compressor is switched off by the control module via the A/C clutch.
