You guys reckon it's mainly low MPG when the car is cold at the start of the journey then ok after that?

What I mean is you start it in the morning and the enging is stone cold i'd class that as a cold start and MPG would most probably start off really bad then gradually get better, but on a 2nd journey if the car was started from semi cold engine as in not stone cold you reckon you should get better MPG on the 2nd journey?

Just wanted to see what you guys reckon.

Yes will be pretty poor mpg for a while, but as soon as engine has some heat in it, it should go up quickly.

Hi, sorry to crash thread, but when you say low mpg, how low are you taking about on trip computer?
reason i ask is i have 130 model and my trip rarely shows more than 42mpg average on a 30 mile motorway/a road journey to work. ive replaced maf thinking it was that but its no better.

any thoughts?

mine smokes like f**k in this weather.
I do a 50 mile commute and getting around 45-48mpg sat at 70-75mph.

Our Polo has dropped almost 50miles from it's usual MPG so far. Cold weather is cack for diesels on start up.

Blue smoke indicates oil.... how blue are you talking?

the blue smoke is only on start up its not to bad as once its running there is no smoke.
could it just be unburnt fuel?
the car is due a service in about 2k miles and its on a 2 year or 20k service times could it just be the fact it needs the service.
had the car looked at on the vagcom 2 months ago no problems then.

A colder engine will give poor mpg whilst it is heating up.

I've always found I get better performance in winter (perhaps its denser fuel/air than summer), but as a result, I almost always loose about 7 mpg.
