Notes:
◆ If necessary, obtain radio code before disconnecting battery.
◆ In vehicles with electrically adjustable seats, move the seats back as far as possible before disconnecting

◆ A heat exchanger has been installed in vehicles with map-controlled cooling (to be introduced gradually as
of model year 1999 vehicles with 1.6 l engine) which has been adapted to the different usage conditions.
The following must be noted for this heat exchanger:
- -> The flow direction of the refrigerant in the heat exchanger is not marked at the refrigerant connections
(observe feed and return flow).
- The heat exchanger can be recognised when installed by the metal refrigerant pipes (as opposed to plastic
pipes as in other versions).
- Reduce pressure in cooling system by opening the lock on the refrigerant expansion tank
- Unclamp and disconnect both refrigerant hoses to heat exchanger in heater (e.g. using special tool V.A.G
3094).
Notes:
◆ Mark both refrigerant hoses before disconnection.
