    The LEVEL sensor is part of the coolant bottle mate, If its the TEMP sensor your looking for it will vary depending on what engine you have, 1.8T will be on the right hand side (passenger) of the engine bay in a plastic housing bolted to the block.

    You mean the one located near the airbox? I.e. the green temp sensor that sits in a type of T-housing thats part of the coolant pipework?

    No cheif, ill try and get one, you wont be able to really see the green as most of the body is hidden within the housing.

    i just replaced the temp sensor on my AMK S3 as vagcom said intermittent fault.
    it was really easy todo, its in a horizontal coolant hose between the air intake box and the block running front to back. mine was green and had a connector with 4 wires going to it.

    definitly worth changing if you are getting startup issues

    aye its the 4 wire one, when I took mine out the shiny bit that sticks into the coolant had tarnished bits on it, its only just over a tenner, worth replacing

    My problem was the gauge was flying straight up to 90 after few mins of driving. Its dead easy to change, make sure you clean or replace the seal. A spot of WD on the terminals wont hurt ether :)

    coolant level sensor is in the water bottle, about £13 from the dealers IIRC...... coolant temp sensor is similar cost and located next to the airbox, plumbed into a large pipe with a big black clip holding it in
