Thanks, I could even remove the plastic part in front of the oil dip stick. It seems the screws head just wont turn as the screw head is damaged. Any ideas?

You are talking the two red dots in he below pic?
Or the allen heads into the inlet manifold?

Thanks I could'nt remove the screws. In the end after contacting Seat Windor and Seat Camberley. I settled for specilist called AVIT in slough to perform the work. They did an excellent job and the price was better than both dealers, if anyone needs it doing speak to Sunny at AVIT. Thanks.

I also got the green top sensor, o ring and horseshoe clip for ~£8 from ebay, fitted in ~15 mins and I'm rubbish under a bonnet!

The guide is superb, took a little gentle 'prizing' to get the horseshoe clip off and whilst that came off in one piece, replaced it anyway.

Do you need to disconnect the car battery before doing this work??

trying to change the coolant temp sensor on my mk1 leon 1.9tdi at the moment, but really stuck with getting the electrical plug off the back of the old sensor. how do they unclip (getting the sensor out doesnt look to be a problem).
thanks for the otherwise excellent post.

I wrote a little guide for this ages ago, but it seems to have vanished.

The connectors lock very firmly together and the locking clip isn't always obvious. In the example below I've used the brake fluid cap as a subject, because it's easy to see and it's yellow.

The assembled connector looks like this

You need to pull the locking clip backwards to release the connector.

The disassembled connector looks like this.

End-on, the wiring plug shows a bit more detail of how the locking clip is formed.

Great guide.I was worried about bleeding the air lock out after sensor renewal but seems you don't need too.
Thanks.
