    W204 C250CDI Thermostat.

    Hi, My trusty 2012 W204 C250CDI has a dodgy thermostat, I strongly suspect. Takes way too long to heat up, and then falls to 60c driven gently. Heater output is poor. I've checked the gauge, and that is fine. So, failing thermostat. Is replacement straightforward, or requiring magic...

    C63 FBSW into a C250CDI Coupe

    Spotted this on ebay. My question is - will this fit a 2012 C250CDI Coupe Sport + with COMAND? The item description is prescriptive to the C63, but then considers installation in non-AMG cars. Thoughts appreciated. :thumb:

    MPG - 2010 C220CDI vs. 2013 C250CDI

    Those cars have the same engine. 2010 has the 5 speed auto and the 2013 the 7g tronic. MPG wise the C250 looks to be a lot better! On the highway going super slow I managed 70MPG in the C250CDI. In my C220 I might see 47MPG. Both cars were in 5th gear. Just 30BHP difference between the cars but...
