Hesitation when accelerating ?
My Z's just done over 6k miles now. I've always put a hesitation when accelerating hard, changing gear and then putting my foot down again to just be down to me, but i've noticed lately that its only when the fuel gauge is under 1/2 full.
Now is this just a coincidence or does anyone else get this ?
Car is running fine otherwise and is running on V-Power at the mo.
Thanks in advance
James

Have you tried turning DSC off?
I presume you're talking about full-throttle acceleration - the DSC on my M is very conservative, so much so that it will cut in at any slight opportunity and make acceleration anything but smooth. Most of the time the first thing I do is hit the DSC button after I start the car, unless I'm tired or it's pissing down with rain...

There's no flashing of the traction control light when it does it. I've come off roundabouts full throttle with the light flashing and i can feel it limiting the power but this is more of a jerk. I don't normally notice it but when i do it always seems to be when the fuel gauge is reading under 1/2 full.
Mike - its been running on V-Power for the last few tankfulls and Tesco99 before that. Doesn't seem to make a difference.
I'll try it with DSC off and see what that does.
Cheers folks

me too.. particularly with the steering non-straight.. it seems to limit power when the steering is turned then doesn't show the light.. can be wierd coming up of junctions..sixspeed wrote:I've felt the DSC limiting power or pulling at the brakes without flashing the dash light at me before though.

Thanks folks. Its not traction control as i can feel that happening and its much more subtle (car feels like its holding back). It's on Tescos 99RON for a few tankfulls and hasn't done it over the last week but it'll be interesting to see today if it returns when the fuel drops to under half full in the tank.
Cheers

I have the same but it's only occasionally and I can't find any pattern (DSC on/off, fuel quality, cold/warm) . . . so I'm just as curious about this as you. I've been considering taking it to service, but since the problem is so intermittent it would be hard to 'prove' the problem to the service personell . . .
It is a slight hesitation for a second on my car but then it kicks in, and it's too early to be the DSC, I know the difference from having the DSC kick in while accelerating and the experience is different.

I had an issue with the 3L - Air mass flow problem, a new one sorted out the hesitation.Andy wrote:is it the same thing i get.. at very low revs in second gear (cruising in traffic) then you hit full throttle and it briefly surges to go, then hesitates (almost misfires), then screams off..
I get this fairly regularly... =S

I experienced this around 1 month ago with my 53 plate Z4 3.0. It was as if there was a lag with both reponse and power and it seemed as if full power was not being obtained. Then the car would not start and it turned out to be the fuel pump which had completely died. Be warned, an expensive bill potentially from your BMW dealer.
