When I bought my mk4 golf 1.6se 8v 1999 the temp display registered 0. I put a new temp sensor on from eurocarparts it now registers but only at about 80 degree. So I bought a new one from VW and it registers at 80 only, my wife took it for a 4/5 mile drive and it made it to 90 but she said it fluctuated.
I doubt both sensors could be bad, so something is not working right.
I'm having a random educated guess at perhaps the thermostat ? (only from reading I guess this)
Would anyone think this is likely, or if I'm barking up the wrong tree ?
If it is this where might it be located on this model and is it a simple to change part from a hobbyist ?
Thanks
