170tdi BMT with DSG temp gauge fluctuating.
Had the emissions fix couple of months ago and apart from an increase in fuel consumption of around 10% (measured, not using computer) has been fine, if anything it has eliminated a slight flat spot at low revs. However from last week I note the temp gauge on some journeys now struggles to get to 90 (can take 20 miles or more) and drops when coasting or on a light throttle. VW dealer cannot find any fault codes, car drives fine, stop-start all works as it should. Any clues?
