With this post series I want to take coverage over the engine which gave me some delights and nightmares as a daily car for some years; We are talking about a conservative, bottom range, underpowered, brave in the middle range, liter and almost a half vw petrol engine.
My experience
The way I experienced this engine was in an mk6 Volkswagen Golf, a rather unpleasant way cause of the weight to power ratio, clearly being the most dissapointing feature of the car itself.
Just 59 kW / 80 ps for almost 1.300 kg which makes a 0,045 kW/kg power to weight ratio, in comparison, a first generation 1.3 liter Golf weighted as much as 930 kg with 44 kW / 59 hp. That still makes 0.047 kW/kg. Slightly more than the 30 years later model.
Even in this configuration the car manages to be fun to drive on twisty roads due to the light of the front end. It kinda likes to move sideways completely without under or oversteer but tending to understeer given extreme situations. The softnes of the suspension seems to help balancing the weight although. Still need to try with different dynamic setups.
In regarding to maintenance and knowing that this car enjoyed a sporty driving always, the following seems enough to say that we have a robust engine:
- Castrol Edge 5w-30 every ~10.000km
- new plugs installed and intake plastic union repaired after 80.000 km(union between both pieces that form the intake broke the glue seal/union and created a leak of air in the intake between the throttle body and cilinder head, happened always idling due to the increased vibration, I suppose, and the ECU jumped into emergency mode not allowing to throttle and keeping the engine around 2.000 rpm If my memories are correct).
