Hi, I'm the owner of a 320d e92, and I have been experiencing something over the last few months, which is a lack of power.

This doesn't happen every time. Sometimes I start the car and it is perfect, others, when I pull the engine revs a bit slower, makes noise but it pulls much less!

I've read some things about an actuator thing but have no idea if it can be related.

Thank you in advance

I would send a box if you fixed my problem and I were in the UK!

First of anything, get it to a local indy and to check if any fault codes!

Sounds like sticky turbo vanes or actuator

No codes what so ever! From what I've read the actuator doesn't throw codes.

For example, today and yesterday its been strong like hell. Tomorrow is a mystery!

I agree with the acuator theory, but 1st you must check it is a definate lack of boost when the power is low. If that's the case then the actuator can be removed for checking.

How can I accurately determine this? Shouldn't this issue throw a code?

I've read something about BMW not replacing only the actuator. Is this true?

Unfortunately don't really like the look of the boost gage in the cabin of this type of car. If it was a more race inspired car, but this is a DD. Perhaps a dyno... Although the issues doesn't always happen

I really wouldn't rely on an error popping up as my entire turbo went last month, cost me £980 in all and no codes apeared, just down on power with no boost. Unless you'resure by the feel of it then a boost/pressure gauge on a pipe that can be connected when showing the fault would prove it your car is lacking boost.

Google Midland Turbos, they can check the Actuator off the car and are the people who rebuilt my turbo.

Unfortunately I'm not from the UK so I'll have to see if BMW or some other guys can check the actuator.

It's something to keep in mind! I will look into it, thanks
