❑ At the start of production, the A/C compressors manufactured by “Denso“ (type “6 SEU 14“) were instal‐
led. A/C compressors from other manufacturers (for example “Sanden“, type “PXE 16“ or “ZJX“) can be
installed later. Refer to ⇒ Refrigerant R134a Servicing; Rep. Gr. 00 ; Description and Operation and
Electronic Parts Catalog (ETKA).

the exact part number, refer to Electronic Parts Catalog (ETKA).
Note
❑ If a new compressor has been installed or new refrigerant oil has been put into the A/C compressor (for
example, after blowing through the A/C system), the A/C compressor must be turned by hand approxi‐
mately 10 revolutions. This ensures that the compressor is not damaged when activated.
