Mk3 1.8 Fuel Consumption
G'day,
I have been driving our Mk3 the last 2 weeks, which we recently bought for our kids to learn to drive in. I have noticed that the fuel consumption is particularly poor, chewing through a tank of premium in about 300km, which does not seem normal at all.
Last weekend I found a few things, notably a loose timing belt (a reminder to all to check theirs perhaps?), and ignition timing that was out a fair bit. Those fixed, the car felt much better, with noticeably more power. This weekend I have checked the resistance of the coolant temperature sensor both hot and cold and it seems to be functioning correctly.
What I did find was a broken dipstick extension, which means that the dipstick was flopping around with no seal to stop air getting into the crankcase. Given these car's engine recirculation and ventilation systems, could this cause poor consumption?
Any pointers on what else to check? Thanks.
Rob.
