Default Coupe/NG Temp sender

Morning!

I'm trying to replace the temp sender on the Coupe.

The part number on the current sender is 035 919 369 L, the number listed on 7-zap is 035 919 369C.

The L is a 4 pin sender, the C is a 3 pin sender. Everything I can find suggest that the 3 pin sender is a replacement for the L (despite it being the earlier suffix).

Was the 4th pin superfluous or is there something else going on?

The common listed aftermarket replacements (searching on both part numbers) is the Mahle TSW 46, which is a 3 pin part.

I've been thrown into a state of discombobulation by this one.

It's also commonly called the MFTS.

Just be aware of the poor quality ones which give a wrong reading. Meyle being the worst examples.

Wise words..........too many buy cheap and then report wrong readings.

I did a crap load of reading on this as I also needed the 4 pin.
I found Audi still did it for something like 170 or so, right.
The 3 pin ones still have the same number.

There is a bloke in the USA who took a load of them, ( 3 pin ) and found they still actually worked in place as the 4 pin, however the 4 he tried all had slightly different resistances and gave slightly different temp readings, he ended up trying several more and found one that gave the nearest reading to what the actual temp was. Mine reads just slightly on the hot side of normal during this weather, the fans still kick in correctly from the other sender unit and I don't seem to have any issues. Now I know it is just slightly high I'm fine with it, also being a f*&*& sh**&t bag of a thing to get to this one was staying.

Very much my point of view when it comes to the gauge.

As long as it’s consistent I’ll be happy.
