After picking some brains, got a 05 plate 320d auto, had a problem Wednesday as the wife was driving home it started blowing blue smoke from the exhaust, she called the RAC and he suspected turbo or breather filter.

The car was taken to a local garage they they said turbo was ok no play and no signs of oil (should be it was only fitted 18 months ago). So they replaced the breather in the cam cover, new air filter. She collected the car last night and driving it this morning it feels well down on power and doesn't seem to want to kick down there's no unusual noises and no smoke.

Any ideas, maybe a connector or pipe they haven't put back, the garage isn't open again until Tuesday and I need to use the car over weekend to visit relatives.
Thanks in advance
