Hello, I'm thinking about purchasing a 2011 C350 with the m272 from a family member. The car has only 62000 km on it. However, I've noticed the fuel economy is worse than the factory numbers, it produces a bad almost rotten egg smell sometimes after driving, and the exhaust smoke is very white...

Hi All One of the reasons I chose to purchase a GLA45 AMG is that on the review sites, and places like Autotrader, the fuel economy listed for the car is roughly: Urban mpg: 34 mpg Extra Urban: 50.4 mpg Average mpg: 42.8 mpg I've had my 2015 GLA45 for several months now and I'm not...

Just bought a New (to me) CLK. Got a few things that need sorting on it - which I'll post in the relevant sections. Photos to follow once I have sorted a few minor cosmetics on it (missing wheel badges etc). HOWEVER - I have now just used up the first tank of fuel bringing it home and a...

Have a E220CDi Avantgarde. Looking into how I can improve fuel economy - after doing all the usual things. Firstly - has anyone any experience of CHIP TUNING Diesel Boxes - which cost between 60-100 pounds - supposedly very easy to fit and give a 20%increase in BHP and Torque and around 15%...

Hi All, Quick question on real world fuel economy and what you're actually getting (which is not necessarily what the trip computer states). I know the trip computer isn't very accurate so I run a spreadsheet and always fill up, even the spreadsheet can have inaccuracies due to the pump...

I had to go to Gatwick this morning, first I filled her up with 95 Ron unleaded 'Tesco special' fuel - because I had a 5p off per litre voucher. Ran 70-72 MPH all the way there rarely exceeding 3000RPM, did exactly the same on the way back but had a mad 3 miles of over the speed limit fun -...
