Hi gents, <o:p></o:p>

Have a bit of an issue at the moment and just wondering if anyone can shed some light on it for me.<o:p></o:p>

I changed my temp sensor about 3 months ago as it was being very temperamental. After changing it everything was ok and sitting bang on 90deg. Ever since winter has come I have not really got above 70deg, even after a long drive around town.<o:p></o:p>

I've had a search but not found a definitive answer.<o:p></o:p>

My initial thoughts were:<o:p></o:p>

Faulty temp sensor???<o:p></o:p>

Thermostat???<o:p></o:p>

What are your thoughts please?<o:p></o:p>

Cheers<o:p></o:p>

If you give the car a blast the heaters should be too hot, if not I would be be changing the thermostat.

On the pd engine it's a total DIY job but I would honestly advise geting it from VW, along with the o-ring.

I went the QH route and the rubber seal was positivly rubbish which caused leaks.

cheers guys. the heaters are fine so i may give the temp sensor a go again. i got the temp sensor off the dreaded ebay so this could be my problem. hopefully i'll get it sorted soon and see the mpg rise again.
