why is it reading wrong?

it is going off the gauge it is going passed the red mark easy when it is not even hot

what did it do with the old guage in?

have you earthed the gauge? It may need an earth strap from the body of the guage, try it. Thats what I needed on my 300tdi fuel guage when it was playing up.

May have a short some where, the lower the resistance the higher the gauge reads. Try disconecting the temp sender if it still reads high then theres a short somwhere

or

If its a Disco engine you may need to change the sender, Steve Parker sells the correct senders so that the gauge reads more accurate.

Are you using the TD sender in the Tdi engine?
