Am I the only one? Gearbox behavior F11

53 posts in this topic

This is irking me more and more and I hope there is a solution you guys might now about...

 

I have the sports auto on my F11, it also has VDC, I mention this as I usually pootle about in comfort mode, because you know, UK roads and 19" runflats... am I right? 

 

The gearbox is doing my nut. I read before I bought it that it was super smooth, the best BMW put in a car, yada yada, mine isn't. It's dim witted IMO, say your coasting to slow down coming up to a roundabout, at around 20mph dropping speed it's like it's mistiming a gear change, so you get a slight jolt, think of when you shift down (say from 4 to 3) and the revs go up, you get that forward jolt, would be the best way to describe it, then, if you lightly press the accelerator, nothing happens and I swear this catches me out everytime, I give it a tiny bit more gas and jolt!, as it eventually realizes I've hit the gas and want to move forward. It's the clearest way I can explain it. 

 

I've changed the setting on Idrive to only change the suspension when selecting comfort to see if normal mode does the same thing, it does, I rarely use sport so can't comment. I did some research and it was suggested on another forum a software update was required, I asked the dealer to look at it quoting the forum info (big mistake- they look at you like your a loon) they said nothings wrong with it.  Anyone know what I'm on about here?? I can't be the only one. 

 

I did try a sequence of "resetting the gearbox" where you turn the car on but not the ignition and hold the accelerator pedal down for 30 seconds or something but either I did it wrong or it didn't work.

Drive around in sports mode for a while and see if it does the same.

There is a similar discussion ongoing in the E60 section and its all to do with the bloody adaptations of the box.  It doesn't do what you want it to do.  

 

You want a reset so that it relearns your style of driving.  Pull the fuses, pull the battery terminal off for 30 mins or so, but don't shut the boot lid!

 

I've always thought the best auto for behavior was the one in my Senator, simple 4 speed with torque converter lock up in 3rd and 4th.  It didn't have the facility to learn so just did its job, without thinking!

I must say I'm impressed with the box on my F11.

 

Driven in traffic I only have to brake when coming to a full stop, is slows me down nice and smooth approaching traffic bends etc. in fact I often think if I was following me I'd think it was a manual with the lack of braking.

I had a very similar issue with my e61 530d a few years back - did my head in. I took the car to the dealers about 4 times and insisted it was a fault and not a characteristic - I got the same blank expression and told I was being fussy, I only kept the car 6 months and bought a manual.

I am with you, I love how there is the feature of engine breaking from the gears. I have a similar spec to you on my tourer. My previous cars we big engined Jag XFs where there was no such effect. I have to say I am impressed with the BMW gear box.

Paperjams I guess this is simply a matter of preference, hey if we all liked the same thing we would be a troubled species:-)

so true, I do think my genuinely had other issues too with slamming into gears and very lazy upshifts (car had only done 35k and was a BMW AUC)

So I've got a lemon is what I'm getting from these comments, I'm unlikely to get any help from the dealers going off my own experience and others, what about a decent indy you think? 535iar, would disconnecting the battery only for 30 mins do the job? I'm not even sure where the fuse box is, I'm not very diy tbh. I'd go as far as doing the gear changes myself with the paddles but it defaults back to auto unless your in sport, and I'm not into driving with the stick pushed to the left all the time. 

 

Would a remap of the engine be of use with this issue I wonder, if the mapping is different perhaps the gearbox will behave differently also.

Mine has been doing this lately with a more pronounced effect than usual but I put this down to the colder weather causing thick oil in the gearbox

I wouldn't say you have a lemon yet, it may be a simple fix as above, the software on the box should reset itself, or maybe a software update (if available) carried out by the dealer may fix first.

 

There also maybe a ZF auto box specialist that could offer some advice?

 

These are an astounding bit of engineering though....

I get next to no engine braking in my sports auto. I take my foot off approaching a bend and it just keeps going at the same pace with only slight slowing. I've got to be very quick on the paddles to drop two gears to 6th, let it slow slightly, drop two more gears and once I'm in 4th I get some form of slowing but still need to clamp the anchors on.

 

I'm guessing that because mine isn't powered by the fuel of the Devil, the rotating and reciprocating mass will be lighter and the software will be different to allow better mpg to be obtained by coasting.  Sport and Sport + modes help because you are more likely to be in a lower gear

Its an old trick to get any form of memory wiped, disconnect the battery for a bit.  Not saying it will work in this case.  Battery is accessed under the boot floor carpet you need a 10mm spanner to lift the boot floor up from memory.

 

It is worth going to a transmission specialist and ask them to check for any updates to the boxes software.  No need to go to BMW as the transmission specialist will have the same access to updates from ZF. Ideally you want a ZF specialist.

Maybe the gearbox acts differently recognising the engine has much less torque....

thats good advice I'll look into a specialist thanks. I wish you'd stop banging on about owning a petrol though, yes we know diesels are terrible!! If I can afford to spec a new bmw one day I'll get an i version.. ok? haha just pulling your leg.

 

incidentally mine coasts for ages too, the thing hardly ever gets above 2000 rpm on the roads around here under normal driving so no revs to shave off in a higher gear.

I totally agree with re-setting the auto-adaptations to allow the gearbox to re-learn the way you drive it, good place to start as it merely costs you some time.

 

One question I have is how many miles has the car done, if anywhere near 100k a fluid and filter change may well improve matters.

ZF say anywhere between 50-75k for oil and filter change.

 

BMW will say sealed for life, but I know who I would believe.

The adaptations are learnt constantly so I doubt it that tbh but worth a try I guess.

 

Yours sounds like mine does in sport mode.

 

In eco mode I get a soft throttle response and very lazy drive, coasts for ages.

 

Comfort is just right. .. some engine braking but still need the brakes. Bit Laggy if you want to move off quick though.

 

Sport mode is harsher changes and much more aggressive engine braking. 

 

I do know what you mean about the response when coming off engine braking... slight touch of throttle and nothing, push a little more and off like a scolded cat lol. only get that in sport mode which IMO is really only any good for quick getaways or the drag strip at the tolls on the servern crossing.

Post August 14 or so, the gearboxes are the GPS-enabled ones which will change down in anticipation of roundabouts, junctions and sliproads (etc). Pre August 14 cars are just the standard lazy 8 speed boxes that always try to keep the revs low, so often get caught out or need paddle intervention.

 

Poor shift quality (as per the OP) is normally an indicator that it's new gearbox oil and filters time.

I'm irked to do it. BMW won't help me with the problem, and I've got warranty - so why should I be forking out even more money on expensive ATM oil and filters when this should be sorted by the manufacturer. It's daft. Just playing devils advocate here.

Thanks for all the replys guys, I mean, I'll consider doing an oil and filter change, ( I probably won't unless it gets worse) sounds to me like it's fairly normal what I'm on about, although never had it in the 5 speed auto on the E39. Perhaps I'm on the far end of normal where a minor adjustment here n there is the difference between "normal" and "slightly abnormal" which is what I've got

 

just incase others come here and decide to do an oil change, from my research I've come across ZF lifeguard 8 transmission oil. It's around £26 a litre on ebay, Or

 

http://www.realoem.com/bmw/enUS/showparts?id=MX52-EUR-03-2011-F11-BMW-530d&diagId=24_1137

 

Part number  24118612901  which is a kit, oil pan fluid and filter. I assume it means oil pan gasket. 

 

edit: seems I was wrong, looks like the filter is built into the oil pan.

Yes you need the complete pan and filter assembly.

Try this (copied from another forum):

 

1) hit start button once to turn on power (Don't start the engine)
2) then press the accelerator down to the floor for 5 sec 
3) then hit start button once to turn off power
4) then remove foot from accelerator 
5) then wait for 2 minutes
4) then start the engine like normal and try it out!
