Thanks ap0gee for the superb info. I had the same symptoms. I did my 51 plate 1.9tdi successfully today. The water pump on the Diesel lump is in a slightly different place, far right of head with the sensor underneath the pump and difficult to see so had to be removed by feel. So having pics from ap0gees post helped. Its difficult to remove wiring in situ, so I found it easier to pull the sensor retaining clip to remove it still wired first, then undo the connector afterwards as there is slack in the loom. You lose about 2 pints of coolant. Dont forget there is a rubber O ring in the hole or on the sensor....dont let it fall into the waterway ! Replacement was fiddly and by feel too, but with patience easily do-able. Cheers for the helpful post By the way, all my parts (temp sensor, o-ring, clip, Heater motor resistor pack etc) have been sourced from Jorily Skoda who have provided an excellent & speedy service.
