If you ever think I'm off my rocker.. Just put me back in it and walk away... It's the kindest thing
My wife says I never listen - or something like that.

rough ride and jerky braking

Post by Kimz4 » Fri Jun 07, 2019 7:57 am

I have been driving mine for a week, and am amazed people are complaining about the ride? Yes it’s sports car stuff, but nowhere near the crashy ride of my old e89 msport. It’s firm but complaint, and I don't wince when I see a pot hole coming!
The brakes are sharper and will take some adjustment, but it doesn’t take long to recalibrate?

I can’t help but think the new car gets knocked as it’s ‘not an e89’ :| It is wider, but cornering and grip are improved, it’s more nimble and easier to have confidence in. In auto it is incredibly smooth, using flappy paddles it’s still smooth but generally you keep the revs higher, so maybe this contributes to any feeling the car is ‘snatchy’.
It’s really not!

The looks? It is bigger, looks bigger and wider. On smaller roads it does feel wider. It only just goes in the garage! But I welcome the extra cabin space,

All in this girl’s humble opinion of course :oops:

I did notice some vibration and steering issues yesterday and then discovered that I have Land Departure Warning which occurs when crossing a white line at speed, unless the indicators are used. I didn't know that I had got it! It can only be turned off for the duration of the current journey.
I turned off the steering intervention permanently and turned down the vibration warning to medium. That way you don’t get an unexpected tug at the wheel when changing lanes and the vibration is minimum but sufficient to let you know that you are near or crossing a white line. :thumbsup:

Yes I've done the same, the last thing I want is the steering being tugged at when I'm doing 70+. The vibration is now set to minimum, I can hardly feel it. My dealer said that BMW have received complaints and he recommended keeping it turned off.

I also had an issue with the collision warning system, again I didn't know I had it (doesn't appear in the spec sheet). First few times I had a drive I got a red car warning symbol in the instrument cluster with no explanation, the car was set to the most sensitive setting (out of 3 levels), I reset it to least sensitive and no more problem.

When mine was on Runflat rubber I was terrified of potholes! Really crashy (though I have just found a broken rear coil spring so that could be the culprit).

Conclusion therefore is that the new Z4 does indeed have very sensitive braking. Dealer told me they would bed in but i'm still jerking my way round town!! :driving:
Auto gear changes when slowing down are certainly far from smooth but that appears to be a symptom of the car. Be interesting to see if an upgrade in the future addresses this issue.

I have been driving mine for a week now. No issues with the brakes. The ride is miles better than the E89. Interestingly though, I noticed that the tyre pressures were all at 3.1 bars. The recommended pressure is 2.2 front and back or 2.7 for eco-driving. Clearly not checked at pre-delivery!

I've received my new G29 Z4 yesterday and encounter the same issue as well. Car starts to jerk a big time when decelerate and switching from 3rd to 2nd gears. It gets pretty annoying during traffics and long ride.

Today I am driving to the dealer and see if it can be solved.

I know this is an olb post but did you get any joy from the dealer as I am also having difficulty with the over-sensitive brakes? The auto gear change is fine but still makes it hard to come to a smooth stop.

The brakes will ease up once they bed in. I have t felt or heard anything like you explained with the gearbox. I’ve found it to be incredibly smooth and well rounded.
