Re: Jerking when accelerating...
Hi
in 2005, I bought my E60 520i Inline 6 Cyliner 2.2litre. I had also experienced the same problem like you mentioned, especially when I am doing a turning in.
At 1st, I thought maybe the engine was cold (going to work in the morning), but just like you - the jerking occurs intermittently and its frustrating becos you can't replicate it when you go see the Customer Service Advisor. I visited PML at least 3 times and these were explanations below
Anyway- I had mixed stories from PML. And these were some of the comments from CSAs :
a. The 520i has a 6 speed transmission carried over from the exiting older 520i model and the tranny and engine doesnt synch well and so you get the jerky feeling, so can't really solve your problem. I wondered why the 523i model has no problems. Try driving in Sport Mode (DS) and that should be fine. (I was thinking what??? Drive in DS mode all the time?)
b. When you come in your next servicing, we will upgrade your Software and that should go away
(which of course didnt go away because it still continues to intermittently appear). I was actually very frustrated.
c. One even shruges his shoulders and said, " yeah so ? It's a 520i 2.2litre and that its a 'known problem' " . and I was pissed because it was like a masked sarcasm saying that if you wanna buy a 5 series, and don't kow-peh if the low-end model got problem.
I eventually got it solved, after my 3 yrs onwership timeline (when it was out of warranty). The potential problem was probably (like one of the bros said) the ignition coil or fuel injectors. I recently replaced my ignition coil and injectors and the jerks (intentional metaphorical pun for PML) have disappeared now that I am using 3rd party servicing agents.
And BTW the beemer engine gets smoother as it ages well. Not sure if all the fellow forummers agree - but I feel it in a 6 cylinder engine model.
Dont get me wrong, I loved Beemers, its just that there are times, I don't like the PML attitude.
Fellow bros, dont flame me, I am saying PML (the company) and NOT targeting any individual CSA or engineer in PML.
Lets do a reality check, you read this forum, and you can see -fellow drivers organizing to bulk buy the 3M anti-friction tape, to line the doors because there are squeaks and the tape solves the noise problem. Its a KNOWN issue. I have owned 320i and then on to 5 series... and yet PML charges you to install the tape. One would think that if you paid premium $ for a premium branded car, PML would have at least have the decency to ensure that such things are paid attention to without costs to the owners. I have been driving for over 30yrs and in the past have ownded and driven Honda, C and E Class Benz, and Ford . And their attention to detail and delivery of customer satisfaction tops PML any time.
Cheers, I think if you can put up with the occasional jerks, then wait till your 3 yr warranty is up and get a 3rd party BMW service agent to check it for you.
