Here's the scenario....

When I'm cruising along at speed, I remove my foot from the throttle. Then, no matter how gently I touch the gas, the car exhibits a slight but noticeable jerk in accelleration. In other words, there's no way for me to reapply my foot to the gas without feeling it.

Even if I'm not trying to accellerate - just to getback to the proper cruising throttle position, there's no way to do it smoothly.

Has anybody else noticed this? Note that my car is only 4 days old and has < 200 miles.

Thanks

Richard.

 

Welcome Richard!

Where are you from?

Have you driven a stick shift before?

You need to get the feeling

The car is very new and it (and you) needs a break in period.

 

What you will need to consider is replacing the clutch delay valve (CDV). It will greatly improve the smoothness of your manual, especially around town. Should be able to find this documented via search on this forum. Cost is about $35 for the part, and an hour of labor. It gets rid of the "grab" when you push in the clutch, especially in the lower gears. I pretty much hated the manual until I made this easy change.

Enjoy your ride!

 

All:

Thanks for the early attempts at help. Allow me to post my credentials. This is my 9th BMW- 7th new. 5th 5 series, second e60.
ALL have been with the proper (manual) transmission.

Now to clarify the issue a bit. This has nothing to do with the clutch. I'll be in gear, cruising at, say, 60. Foot nowhere near the clutch pedal, right foot off the gas.

Just touch the gas.... 2 millimeters, really slowly. the car jerks a bit from 'coasting' to 'maintain speed'.

Any other thoughts? My feeling is that it has to do with the transition from 'foot off the gas' to 'foot on the gas' mode in the drive-by-wire software..

Other than that, this car is a BEAST. a BEAST I tells ya!

Richard.

 

Richard -
What car are you driving? 550?

And about that Clutch Delay Valve... wouldn't that hurt performance when racing?

 

It sounds like the drive-by-wire is twitchy.

 

I brought it to the dealer today, and went for a drive with a service manager. He was able to replicate the issue, and said he'd bring it up with "BMW Central Command" (my term) in New Jersey.

During the drive - without saying so, of course - I could tell he was thinking 'Wow - talk about a minor complaint - this guy must be nuts'. He was very nice about it, though.

So I said 'As gently as you can, remove your foot from the throttle'. He did it several times, and each time it was abundantly clear - as the passenger - that a discrete state change had taken place. A slight nudge or jerk.. (so with me, that makes two jerks in the car, I know.. )

Slight or not, it's clearly perceptible both getting on and off the gas. It's just not right for a brand new car, you know?

 

I have a 550 (production date 8/31/2006) with 920 miles and have the same problem. It's not a show stopper, but it is annoying when you can't drive the car smoothly. I'm anxious to hear if you can get this resolved. I just got mine back from European delivery and haven't had it in for service.

 

Sorry to say, too young or too do...

Learn to drive!

I dare you ladies at any time on ice with a stick shift standard E30 325i

 

Why the hostility ricracing? The gentleman obviously has experience with bimmers and knows of what he speaks. i am sure that your post is neither relevant nor helpful.
