Hi Folks,
Please take a moment to help me - I'm at the end of my tether.
I have a 2004 W203 271 engine C180 Auto. ~60,000 mile on the clock.
I bought it about 17 months ago.
Problem: The fuel consumption is awful. Always has been. Around town I'm getting about 20mpg avg. 28mpg on the motorway, if I'm lucky.
I'm getting about 230 miles from a tank.
The EML is on and has been for some time. I took it to a garage ages ago, it was complaining about the O2 sensor, I got it replaced. The fuel consumption didn't improve and the engine light came on a few weeks/months afterwards.
Some questions:
1) What can I do to get decent mpg?
2)What mpg should I expect from a car of this age?
3) Is the O2 sensor the problem? Is it simply inputting too much petrol to the engine?
4)What part does the MAF play in this? Could replace it solve the problem?
I'm hoping it's not oil in the wiring loom. I simply don't have the money to fix it (due to buying a house since buying the car - it's eating all my money!).
If it is oiling the wiring loom, I'm going to have to trade it in and if so, I'm not going back to Mercedes again. I had a manual C200 CDI before this one and had nothing but bother from the DPF. I traded it in to buy this C180. Petrol meaning having no DPF.
All help very much appreciated. Thanks!
