Hi,

I'm new here, after many trouble free years with my E46 I bought a E91, 325i / 2005 / 93K miles. It has Vanos faults when i bought, but i read this is a common problem..so no worries at this time.
I changed the solenoids, faults came back - cleaned the check valves. Made a engine flush +new oil/filter/filtercap and replaced the checkvalves with new ones.
meanwhile i also went to a garage for changing ATM Oil +filter and gaskets.

I notice at constant speed and light throttle the accelertion is wavy, like one second it has power next it dont have ..very equaly like a sine curve.
with vanos faults and probably turned off camshaft shifting it dosent do this.

as next i got a Disa fault and a broken flap .. I replaced both Disa and the CVV
still had some missfires at idle so changed spark plugs and coils and a software update from bmw
now the idle is fine. just after first start it swings one or two times.

no fault codes at all
but it still do this wavy accleration (maybe somtimes a tiny choke at the first move after long idle when it shift second to third gear )
got a new maf senor - but no changes

I noticed a bit oil in the connector from the eccentric shaft sensor .. could this sensor cause the inconsistent power delivery without fault codes in the DME?
or am i on the wrong way searchig the problem in this direction
