AFRICAN CAR, SWINGS, MEANS CRANK HERE.
HERE ONLY DOORS SWING AND CRANKS SPIN./
NO ENGINE TOLD
2.0L PETROL
2.7 L PETROL
2.0L CRDI DIESEL? NOT TOLD ENGINE.
SO (TOSS DICE) LAND
GAS (PETROL ANSWERS) ME.
SPARK DEAD OR ENGINE DEAD.
NO MILES ON CAR, (ODOMETER)
2009 IS 14 YEARS OLD AND NO CAM BELT ON 2.0L LASTS THAT LONG, AND WHEN SLIPPED BELT OR SNAPPED,
COMPRESSION IS NOW ZERO OR 1/2 NORMAL
AND SPARK IS NOW DEAD UNTIL REPAIRED
OUR CARS HERE THE CAM BELT IS CHANGED EVERY 60KMILES OR 100KM.
OR IT BREAKS.
A TECH DOES 2 THINGS, SPARK DEAD
SEE IF CAM IS DEAD (NOT SPINNING)
THEN CHECKS THAT CAM IS STILL TIMED AND BELT NOT A WRECK IS I FULLY EXPECT.
8 km per litre, or 12.5 litres/100km is certainly a bit heavy for that model, but not disastrously so, as in city driving it was rated at 10 L/100 km when new by Govt agencies where I am in Aust.
So the usual suspects in an older car are
- dirty air filter
- low tire pressures
- spark plugs worn or fouled
- ignition timing incorrect
- fuel pressure too high
- fuel injectors worn
- evap canister filter blocked
- emissions system faulty (EGR valve or Vacuum Switching Valve)
That depends on the engine and the fuel used. My W124 4 door 2 liter petrol engine running on Regular CO95 does 7 liter/100km on road and 12l/100km it a very congested city.
From the owners manual 1998 model
manual transmission
city 12.8 litre/100km
extra urban 6.9 litre/100km
average 9.1 litre/100km
215 CO2 emmission (g/km)
auto box
city 13.5 litre/100km
extra urban 7.5 litre/100km
average 9.6 litre/100km
228 CO2 emission (g/km)
