I've suspicious of my thermostat since getting the car nearly 12 months ago. It's a late 2011 350cdi (265hp) and it seems to hover around 80 on the gauge even with a good long run. Measured it today using a bluetooth obd reader and it settled around 76-78deg C. I am aware the should be operating nearer to 90deg C. Anyway, ECP and GSF don't have one listed, which is a pain. Do we have any associations on here with any main dealers who offer a club discount or similar? Thought it work an ask. Thanks.
