Technical modifications:
Basic 132 kW (180 bhp)
– Cooling water afterrun pump (approx. 10 min)
– Secondary air system
– Piston (modified), thus changing the
compression ratio to 9.0 : 1 from 9.5 : 1
– Manifold (new exhaust and flange)
– When EU III takes effect, there will be a 2nd
lambda probe downstream of catalytic
converter for catalyst monitoring
– 2 in-line charge air coolers
– Injection valves (higher flow)
– Quick-start sender wheel
– Piston cooling by oil injectors
(volumetric flow adaptation)
– Hot-film air mass meter with reverse flow
detector HFM5 integrated in the intake air
filter upper section
– Single-flow throttle valve unit integrated in
the electronic throttle control positioner
