Audi coupe S2 temperature guage

[Darron Edwards]

My S2 has had an intermittent problem with the temperature guage going dead for a while, I fitted a new guage and sender but the problem still kept cropping up. In the end I found that it was the 4 pin connector that fits onto the sender unit in the engine bay that was at fault. the connections are a bit pathetic even when new so i soldered some tails onto the sender and put my own spade connectors on. its never failed since. (over a year now) ive heard of people having exactly the same problems on cabriolets and other later Audis. I hope that this info may help somebody. Darron.
