Hi,

Just recieved my new temperature sender (059 919 501A), but where on the 1.8T is it placed?

Pictures ?

I believe you'll find it located under the L shaped plastic trim that goes around the inlet manifold and it sits in the black housing on the side of the cylinder head on the gearbox end.

Did mine not so long ago, The Pic is enough to go by on the other thread.
