hay all

got a 06 jetta TDI.

after a cold start, until the motor is up to temp, i have a bit of a bumpy idle. and the occasional stale while cold(3 times over the last 6 months)

and iv been getting pretty bad fuel ecconemy, around 6.8L/100 that is with a mix of freeway driving, and gently throttle driving in general.

im booking it in this week, but wouldn't mind thoughts from the more technically minded folks...

the diesel fitter at work suggest a few weeks ago to swap to caltex premium diesel, so i did with little a vale 3 tanks have been through it now.

thanks for any surgestions.
