    I'm thinking temp sensor if you are having problems starting the car, maybe a scan with Vagcom might show something up? If it turnsover, and you can even do it for 10 times in a row, I doubt it's your battery and I'm not sure if a duff MAF can effect starting the car.

    Vagcom is a diagnostic tool, you need someone with it to scan the car for faultcodes, knackered temp sensors usually shows up as a fault if it's broke, best to get it scanned to be sure though, I'm making a wild guess...

    Have you tried something simple as letting the fuel pump prime?

    Turn the ignition on and wait a couple of seconds till you hear the whirring pump noise stop then turn it over...

    EDIT : Just read your post again about worse when hot so you can forget the above.

    took me about 20mins once i located the sensor as you cant see it from under the bonnet.it better if you can get the car up in the air.remove the plastic under tray and just above the casing were the oil filter screws into you should see a little black plug thats bolted to the block with a 10mll bolt.GOOD LUCK

    actually when I bought my car, i had exactly the same problem. Breakdown guy who came to rescue, tested and advised a new battery. He started the car for me using jump leads, drove to Halfords, bought a new battery, borrowed some tools with the guys there, fitted new battery and problem sorted..

    It was a crank angle/speed sensor for me

    I had the same problem a few months ago (Y reg S3). Turns out it was the crank angle sensor (which funnily somehow has some bearing on the fuel pump as well.). Got it changed, and everything is perfect again.
