2001 C200 Kompressor terrible fuel economy!
Hi everyone.
I am new here and this is my first post.
I have been reading up on the forums for weeks trying to figure out ways to get better fuel economy as some people can get down to 5.9L/100km on the freeway whereas my best was around 7.7L/100km. But before I could start implementing ways to improve my fuel economy, a problem has arisen. Hence why I joined the forum.
Since a couple of days a go, my 2001 C200K's fuel consumption has doubled!
I have only this car for about 3 months and it is coming up for a service in about 500kms.
It has 168K km on the clock.
Usually around town, I'm seeing between 9.5 and 12L/100km. But now, It is hanging between 16 and 20L/100 km and saying that I have a range of about 350km on a full tank of 98 octane! And, I have been driving with an incredible light foot to try and preserve fuel.
Apart from the terrible fuel consumption, I haven't noticed any other problems such as lagging or power loss.
I have one part that I noticed break at the same time of the incident (extreme fuel consumption) and that was the breather hose (part number A111 0182982) on the top side of the crank case. This part is leaking a small amount of oil and I have had to put in about 1 litre since its last oil change.
I have it booked in for a service/repair on the 18th of Feb at an independent mechanic.
One thing I have tested is the MAF sensor. I unplugged it and drove it for a while at operating temperature and didn't notice any improvement in fuel economy.
I don't have an OBD2 code reader so haven't been able to get codes. I imagine that would be a first step?
Any speculations as to what could have cause this sudden problem?
Cheers,
Simon
