Hello all - my Octy's developed a weird fault over the last week or so. Every so often the temp needle will drop from the halfway mark gradually down to about the 1/4 mark. It never rises back up again. If you turn the engine off and back on again, the temp needle sometimes shows back to the halfway mark, sometimes goes back to the 1/4 mark. I've checked the fluid levels, they all seem OK, the car's still driving fine so I don't think it's anything to really worry about that much. So, prob a new temp sensor is in order. I've changed one of these before on my old saab but never on the Skoda. I had a look on Butts and the only thing that looked like it might be right is this:

059919501A - Temperature Transmitter Switch for Octavia/Superb. Is that the right thing?!? This is for a 2000 year Octavia TDI 110.

Any clues gratefully received!

Cheers - Jules

The part number of the dual temperature sender is 059 919 501 up to chassis number 1U-X-134 201 and 059 919 501A from that chassis number. The latter part cost me £26.28 earlier this week from a Skoda dealer. It is £23.65 from Butts but excluding delivery.
