I bought one of these a year ago , 18 months old personal import. The magazines all wax lyrical about the engine and rate it one of the best.

I have had recurring problems with rough tickover, lack of or inconsistent power through the range - also it is very slow on the take up if you try for a quick getaway before it goes - disconcerting if you are pulling out at a junction or roundabout!

It has been in on several occasions, had the injectors replaced once, and reset a couple of times, the turbo replaced - these make a short term improvement but the situation tends to revert - BMW dealer say that they can\'t find anything wrong when they test it, and like all intermittent things, tends to behave when it goes in !!


Overall it is not as smooth and quiet as I would expect and the power seems patchy.

Any similar experiences or ideas ?

Think this problem is usually caused by a duff Mass Airflow Sensor (MAF).

Have a search here:

and you should find all the info you need.
