That's the valvetronic servo motor (these engines don't have a conventional throttle flap but rather control airflow with variable valve lift). I wonder if it's a problem with the sync of that. I would defo be giving this procedure a try.... http://mhhauto.com/Thread-E90-320i-valv ... to-failure
Wouldn’t vvt be connected with variable valve timing (vanos) rather than the valvetronic valve lift system?

What car did you move from to the z4 op? Might just be getting used to an NA engine, surprised me when moving from a 2L diesel

I've never known BMW refer to the VANOS as VVT like Toyota would, although in essence of course this is what it is. In most BMW circles, VVT would be the Valvetronic motor actuator, e.g.: https://www.ebay.co.uk/itm/BMW-VVT-VARI ... 1978682202

Sounds like you do have a problem, Just came home from work on an empty dual carriageway in my 2.0i doing 60mph in 6th gear, floored the throttle and bags of power to increase my speed without dropping it down a cog, I'm not mechanically minded so worth listening to more knowledgeable members on the forum :thumbsup:

Someone asked a good question - what car are you coming from?
For my first 2.0 Z4 I came from a 2.0 TFSI A4 that really kicked in when flooring it in the sweet rev range, I felt the Z4 was underpowered in comparison (which of course it was) - although it was a lot more fun to drive :driving:

I have found with my 2.0 E85 that you do have to really push the car and be in a lower gear than you would think but mine will pull away and easily overtake at 60-80. If you cant feel it accelerating properly you most likely just need to drop down a gear, Mine is a six speed so if you have a 5( not sure if they made one) it may be different. Have you come from a turbo/supercharged vehicle as acceleration wise mine is around the same as my wifes 2010 1.4 TSI Scirrocco but obviously there is no "boost" feeling which makes hers seem quicker.

In answer to the question, I have a Maserati 4200 and now I can imagine you all thinking well what do you expect ? You can't compare it with that. No you can't and there's not much that you can compare it with. However I also drive my wife's 1.9 Polo diesel and a Vauxhall Vivaro van plus the odd motorcycle. So I am very much aware that it's not and never will be a rocket ship. Reading Black abbots description of his cars performance that's how I expected mine to be but it isn't. There can't be much wrong with it though as it starts easily, idles reasonably smoothly, is quiet and will return 42 mpg. Am I right in thinking that the Vanos control the oil supply to the variable valve timing gear? If this is correct could an internal oil leak cause the valve timing to lag a little. This is just a guess and is probably wrong.

Hi, the vanos is the variable valve timing, the oil to them is supplied by vanos solenoids which can get blocked by debris/crud-people have had success removing them & cleaning in white spirit or petrol before reinstalling.
Any leaks will be visible on the outside rather than internally, this is usually just a damaged o ring :thumbsup:

Having put another couple of hundred or so miles on the clock I've decided it's me after all and not the car. I've come to realise that it does go rather well, in fact it's a lovely little sports car. It might seem an obvious thing to say but it's how you drive it that matters. Because it has a relatively small engine to get the best out of it you have to "row" it along with the gear lever, a bit like driving an MG Midget or an Alpine etc. So that's it, I'm happy for now. Thanks to the forum members who offered their advice.

reviving a bit of an old thread here as also a new 2.0l E85 owner and I find exactly the same thing as the OP did.

Always have to knock it down a gear and really does not pick up from 70mph onwards very quickly.

Although mine has only done 50k and I am looking for some health checks and maintenance to learn. seems the vanos might be a good thing to clean up along with the o-rings
