I seem to have fluctuating engine temperature. I'm sure when I bought my 1.4 TDI in May that it was dead central and showing 90 C. But since then it runs lower (and very occasionally at the vertical 90 C position). Sometimes it barely reaches the 80 C mark. This is all very frustrating as I had requested it be swapped as part of a full service I just had. The guy said he had measured it and it was fine for the TDI.
So my first question is at what temperature should the thermostat open? I presumed 90 C or just below.
My second question is does a cool running engine impact on mpg or general running of the car. Certainly I don't want a cool engine in winter if I want a warm cabin I guess.
Is it a big job and does everyone recommend genuine VAG thermostat or are there good equivalents?
Thanks in anticipation.
