ENGINE CODE

Engines are identified by a 3-letter code stamped on the engine. For engine code locations (Scheme 16)- (Scheme 19). Engine codes are also located on the vehicle data plate.

Note. Engine number for 1.8L turbo can be found on mating flange between engine and transmission. Additionally there is a sticker on cylinder head (valve) cover with engine code and serial number.

Scheme 16

Scheme 16: ENGINE CODE

Note. Engine code for 1.9L TDI is located between diesel injection pump and exhaust manifold, on engine block. Additionally there is a sticker on the timing belt guard containing engine code and serial number. Engine code is also included on vehicle data plate.

WARNINGNever replace a fuse with one that has a higher amperage rating. A fuse with a too high amperage could damage the electrical part and cause a fire. On no account should fuses be repaired (e.g. with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.

FUSE ARRANGEMENTS ON FUSE BRACKET/BATTERY - ENGINE COMPARTMENT

The fuse bracket is assembled on top of the battery on the left side of engine compartment.

AUTOMATIC CIRCUIT BREAKERS

The electric seat adjusters or heaters (if applicable) are protected with circuit breakers which reset automatically after the circuit overload has been corrected.

Note. Whenever replacing a fuse, always consult the sticker on the inside of the fuse panel cover. It contains the most up-to-date information regarding the fuse arrangement.
