12 liters/100 k's in a 2 liter? what the?

[dylan8]

they take a while to get moving, 3-5mins maybe? cant say iv timed it, but once it gets going it usually shots up (like you said in 30seconds maybe?), if yours is sitting low get the coolant sensor changed (cheapest part) and if it still is get the thermostat done. What year is your car and kms? some of the parts your looking at just wear out over time

[Arctra]

Definitely sounds like MAF or temp sensor if it smells rich... Could also be injectors leaking... Take it to a mechanic for sure and do a vag com scan.

O2 sensors can also cause increased fuel consumption when they are out, but to a lesser degree, MAF more so.

good luck

Interesting reading guys. Can you tell me the difference between a MAF (Mass Air Filter) sensor, O2 sensor, and Lambda sensor probe? Are these different items, or the same items by different names?

Lambda sensor = O2 sensor

MAF sensor is the air flow sensor and sits somewhere after your air filter before the intake .

Further to this.

The Lambda/O2 sensor is generally placed (I believe, it's certainly on the exhaust side of the engine) in the exhaust manifold or shortly after it, and measures the amount of oxygen present in your exhaust gases. This reading is used by your ECU to adjust the fuel/air mixture for combustion - too much oxygen in your exhaust gases and the car is running lean, too little and it's running rich.

A MAF sensor measures air flow into the engine, and is used as part of the calculation for air/fuel mixtures (it tells the engine how much air is coming into the engine, the engine works out how much fuel should be injected, reads the lambda sensor to see if the exhaust gas mix is right, and if not, adjusts things at the intake level again.

From what iv learnt these parts just wear out over time, these, the plastic brackets holding the glass in your power windows, and broken remote keys are they only problems with this generation VWs

This is right on from how its been explained to me also. So as you can see from manazs discription 1 part can upset another and so forth

hehe you wish

[Golf88]

Hey guys im getting my golf on Saturday, would these problems be covered under power train warranty the dealer is trying to flog me?

[torque]

Unfortunately not I am afraid; check their booklet and terms and conditions before you sign up

[Manaz]

Check what it does cover, what it WON'T cover (probably more important, and I suspect a longer list than what it does cover), and whether or not you're tied to using them for servicing (and at their intervals) in order for the warranty to be effective.

Be aware that even if you meet all their requirements, they'll do their best to get out of paying for repairs anyway.
