winter fuel consumption

[Brandon Rogers]

I think also, colder, denser air requires more fuel to keep the proper
mixture.  Snow tires affect mileage.  More stop n go during snow storms.
Extra idle time to warm up.  I know I sure like the extra power in cold
temps so my right foot gets happy too.

Subject: winter fuel consumption


Every winter my 200 becomes a gas guzzler. With the coldest winter on my
ownership on record (global warming?) it has been the worst. It is
approaching consumption of a 4.2 V8  in city driving. There is no loss of
power, fuel smell, unusual exhaust, etc. VAG-COM data appears to be withing
recommended limits.

The only observation is that when engine is cold simultaneous clutch
disengagement/gas release while driving with no acceleration (2nd or 3rd
gear) on a horizontal road results in noticeable RPM increase for a fraction
of a second. If accelerating it is even more noticeable.

Has anyone seen/solved anything like this?
