• From '97¼ model year, 120 Amp Nippon Denso alternators will be used.

• The vacuum pump is located on the front side of the alternator. This results in better cooling of the diode plate and prevents any loss of power caused by the alternator getting hot.

• The routing of the vacuum pipe and of the oil feed pipe has been changed accordingly.

• This combination is available as a conversion kit for all previous models.

• The positive crankcase ventilation system is a completely closed system.

   All the combustion gases blowing past the piston rings and into the crankcase are passed back into the air intake through a pipe from the cylinder head cover via a positive crankcase ventilation valve integrated in the oil separator.

   The positive crankcase ventilation feed pipe into the air intake pipe has been moved away from the air cleaner and into a position close to the turbocharger. This prevents increased contamination of the mass air flow meter (MAF).

• The positive crankcase ventilation valve near the inlet manifold will be omitted from '97¼ model year onwards.

• The direct connection for the boost pressure regulator will be omitted from '97¼ model year onwards.

• It is actuated by an electric solenoid valve which is controlled by the PCM.

• From '97¼ model year onwards, no idler pulley will be used on engines of vehicles without air conditioning. The drive belt is therefore shorter.

• It is adjusted as described in Operation No. 21 134 0, steps to

• A new, one‐piece, multi‐layer steel cylinder head gasket will be fitted from '97¼ model year onwards.

• When fitted, it is possible to identify the type of gasket used from the front side of cylinder head 1.

1. Multi‐part cylinder head gasket

2. One‐piece cylinder head gasket

3. Shortened spacers

• The cylinder head gaskets are available in three different thicknesses. They are identified by the number of notches.

   1,41 mm: no notch

   1,51 mm: two notches

   1,61 mm: one notch

• When using the one‐piece cylinder head gasket, it is no longer necessary to retighten the cylinder head bolts after 20 000 km.

• New Bosch engine management module (PCM)

• Mass air flow meter (MAF)

• PCM‐controlled fan motors

• New electronically controlled injection pump

• PCM‐controlled boost pressure

• Modified EGR system

• Power reduction when engine overheats

• Electronic accelerator pedal

• Speed control (optional)
