E90 320d smoking...

[thegermancarguy]

A mate has recently purchased a car and it smokes real bad.
Appears to be blue smoke- oil out the exhaust.
The turbo does not whistle/whine, pulls absolutely perfectly even in the motorway.
His is a 2005 320d -160bhp model. On idle the car smokes quite heavily and when you press the gas.
Does anybody have any ideas what this could be? How common are crankcase breather issues on these?

Good chance it's still the turbo letting oil past the seals

Well,

The crankcase breather was replaced together with air and oil filter and some new oil.
The car smoked for a little while when first driven.

Now the smoke has gone but the turbo isn't kicking in. Seems to kick in sometimes after3k Reba which is high.
Again no whining from the turbo!

This is frustrating!

Mileage?

The garage said they would look at the car in the morning. Rung this morning and said strangely everything is fine! They may have left something disconnected but didn't want to admit to anything maybe!

I had mine in the garage for a new washer pump this week and mentioned a cloud of blue smoke on start-up that I've noticed since the frost has come. The mechanic said not to worry, it will probably just be extra diesel injected in for a cold start(?).
It doesn't smoke any other time but feels a little low down on power though.

Lumpy start and smoke ?
Check your glow plugs and glow plug control unit. The glow plugs are beru, the control unit is a Bmw only item. Well it was when I had mine changed.
