Engine mechanical system
Ancillary unit drive
The ancillary units are driven by means of a 7-groove poly-V belt. The ancillary unit drive fitted in the Phaeton
differs from that in the Touareg due to an additional guide roller and the different layout of certain ancillary units.
Touareg
In the Touareg, the alternator and air conditioning compressor are installed in a higher location than in the
Phaeton. As a result of this, the Touareg is capable of fording water up to a depth of 500mm.
Phaeton
An additional guide roller is required in the
Phaeton because the alternator is fitted in a lower
position than in the Touareg. This is due firstly to
the installation space conditions in the Phaeton
and secondly to the Touareg's necessary fording
capability.
