Used it for towing a caravan also and it is the worse car I ever used for towing.
Still under warranty so it will be going back.
There has to be something wrong, should be tracking straight and accurate.

Certainly check and experiment with tyre pressures, as our cars can be very sensitive to running optimum pressures. Also check for odd tyre wear, poor wear patterns are not going to help. I assume it doesn't suffer from steering pull, simply wanders?

How good (central) is the steering wheel when driving straight? If it is a bit off, that can mess with EPS precision in use.

BTW, my F11 (2011 build), drives straight and with precision on 18" run-flats. Steering doesn't wander or require adjustment in a straight line, at any speed. Severe cambers will be noticed through the steering, but even that is minimal and not a daily occurrence.

Take this with a grain of salt. I read on another thread somewhere that there is a "drive ahead" software update that helps? I've pinged my SA and see if it is relevant to my car.

There's a SB called "steer ahead" that the dealer should handle for you for free. I put a up a post about it somewhere on here. It should correct the wondering. It requires a flash of the car so be prepared for that. I never felt mine was 100% better until I upgraded my sway bars. The SB will make t much better

test drove a 530D M Sport last week before ordering the 535D M Sport, it was NONE adaptive and drove arrow straight at 85 MPH no problem, I have ordered Adaptive Suspension on mine.
Never heard of this here in the UK.

Yes! This is it. As a side note, my SA said this update has not been performed so I hope this will help my case! Thanks!

Car's back with the dealer today. They took it for an extended test drive and couldnt replicate the problem. I mentioned a Straight ahead travel handling conversion as mentioned in another forum so hopefully they will look at this.

The tyres are new all round but the steering wheel was off when I first got the car hence the 4 wheel alignment but this is now sorted. It does't seem to centre very well at high speed (60+ mph) and needs constant corrections. The steering is extermely sensitive when needing correction and very light but then when needing to turn (still at high speed) it seems very heavy!
Steering seems to be effected by everything, camber, wind, but sometimes nothing at all.


Just for info what is does the SB mean in this quote "There's a SB called "steer ahead""

and what's the SA in this quote " I've pinged my SA and see if it is relevant to my car."

Not sure on economy, i've only had it three weeks and its been in the dealers for most of that. Last time I looked it was averaging between 38 and 40 mpg but most of that has been around town.

Dealer called me Friday to say they have sent a request to BMW UK about the issue and requested a software update. They wouldn't do it without their permission due to the possibility of frying a module and becoming liable for the cost of repair.

Dealer called me Saturday. BMW UK have agreed to let them update the software but first they want them to check the software version on the car (on what module I dont know) because my cars build date (11/2013) is close to a changeover, (i'll find out about that more when they call today). They them need to take the car on a 30 mile test drive on a motorway (they asked my permission) If the problem exists they will update the software.

I'll post again soon as they are due to call today.

Upadate,

Just picked the car up from the dealer.
They've told me the software is update to date and they cant find anything wrong. I mentioned the Staright ahead steering update but they have said the software is the lastest version and there is nothing mroe that can be done.

I'm going to take it for a long drive on the weekend and see if anything has changed but I doubt it.

Problems I've had in the past with pulling, vibration and wandering.

Control arms
Weak shocks
Run flats
Stock springs too soft
Steer-ahead flash
Bent rims

Things that resolved wandering for me
Replaced rear swaybar with 550
Steer-ahead flash
Control arms
Upgraded springs and shocks

Things that resolved vibration
Replacing bent rims
Replaced warped rotors
Ditching run flats!
