Hi all, Been having an issue with my temp gage fluctuating for a couple of months now, usually only at high speeds on motorways etc. Typically happens when eccelerating. Heater blower works fine cold and hot dependant on what I want, no warm air coming into cabin. No engine noise or anything else noticeable so has made me think thermostat. It was liveable for a while but due to this heat I use the air con but it seems to go off on the motorway along with the temp fluctuating... Anyway, looking on ebay I type in my car model and it gives me the items but then when I click on the thermostat I want it'll say won't fit fit model... anyone know the right one for me to get? I've got a manual 1.6 diesel 2011 Many thanks
