E60 LCI Auto Transmission Fault!

76 posts in this topic

Hi guys,

 


This morning I was driving to work and on the motorway when i accelerated a little the gear didn't drop like it normally does and came up with a message on iDrive "Transmission Fault, please drive moderately".  So carried on driving as there was no hard shoulder but it was like the car was confused in which gear to go into it was just reving up but not going into next gear, so was stuck in fourth revving @ 4k rpm without going to the next.  So soon as I seen hard shoulder appear I stopped, turned the car off and performed the gearbox reset procedure: Ignition>foot on gas for 30 seconds and then started again.  Luckily this got rid of the error and car seemed to drive like normal again.

 

I have read up that many could be the reason to this, such as battery, adaptive transmission needing resetting (which I did, and hope this was it)

 

Going to plug it into INPA to see if any errors were stored, wondering any of you guys have had this issue? Is my gearbox knackered or on its way out?

 

PS: It did the same once around this time last year which did get resolved by resetting the gearbox, not been reset since, could it just mean it needed a reset?

 

Thanks

trans fluid low, sounds like your sump is leaking on the gearbox, I am dealing with the same issue at the minute had to top up 1 1/2 litres the other night, having my sump replaced next week, very common for them to warp and leak as they are only plastic

Thanks for the reply,

 

If the fluid is low or leaking should it not come up with an error about low liquid? Did you get the exact error? Did it go away by resetting?  Is there a way to check if the fluid is leaking?

no, they don't have a level sensor as they are mean't to be sealed for life, but oil should in fact be changed at 70-80k anyway, I'm now on my second sump and fluid change and 120k on the clock

you will have to remove the undertray on the gearbox and if it is wet then its been leaking, I got transmission error on the screen somtimes as when in 5th gear and tried to accelerate it would start stuttering and slipping, error was 4F51 5th gear monitoring, clutch slipping, these boxes are very sensitive to oil condition and level

I got the same message about 2 weeks after having my transmission fluid & transmission sump changed at 60k. That was about 6 months ago. I accelerated moderately hard from a standstill and got the message. Got it again about 3 weeks later and never had it again since, so I don't think it necessarily means low fluid level.

How did you get rid of it mate? Did you do a gearbox reset?

true, in your case it may be that the garage overfilled your box or used the wrong oil, especially since it happened so close to getting it done, overfilling is just as bad for them, and it is a very specific non conductive oil it needs, hear of many stories where garages treat these boxes like normal auto boxes and put wrong fluids in, also there is a very specific filling sequence, has to be filled in 2 stages, at 2 different temperatures, but first place to look would be leaking sump and level, otherwise its a tranny rebuild

Yeah I confirmed with the garage about the specific procedure & oil. They knew all about it and they also mentioned that ZF now recommend a fluid change even though it's supposed to be lifetime. I did do the gearbox reset via the accelerator pedal method - is that the same as DIS or INPA?

I'd be interested in this also, I have done the foot reset, is the INPA reset any different?

The car put the box into limp mode which means you only get 3 and or 4th gear which is why it wouldn't change up until you switched off and restarted.  This protects the box supposedly.

 

There is little point speculating on what the cause is until you get your codes read.

 

It could be anything from the seals between the Mechatronic unit and the bottom of the box to clutch failure.

 

Whats the age and mileage on the car?

 

Did you ever get the box serviced?

 

Im quite interested to know as the E60s appear to be having gearbox issues and there is a real debate over wether or not to get the box serviced.

accelerator pedal only resets recent driving condition parameters, inpa adaptions reset relearns as such the gearbox allowing for fluid change and parts wear, a much more involved reset

Thanks for that info! As I said this had happened to me a year ago and since resetting the gearbox using the foot pedal method it hadn't happened up until today, I hope it is due to the the car having had 2 different drivers driving it which may have got it confused...

 

As for the gearbox oil chance, as stated from BMW it is supposed to be lifetime and I have read a lot about these getting worse or breaking after changing the oil so I have not bothered with it tbh.

 

Going to get the codes read  this afternoon and will post um up on here soon.

 

It's a 07 plate with 120K

Yeah we've read the same things then.

 

Keep us posted but brace yourself as BMW will tell you a lifetime is 120k.

Hi guys, 

 

Got around to scan the gearbox, it stored an error code which is the following: 4F 85 38 00 00 00 00 01 27 5C 23 4F 46 41 4E 00 00 00 00 00 00 00 00 00 00 00 00

 

Any body can help? nothing coming up with google typing all that in..

would still check for low oil as that can cause all sorts of fault codes, means not enough oil pressure to engage clutches, I was told I needed a complete tranny rebuild when I posted the issues I had last week with error 4F51 but turned out fluid was low

Ah great doesn't sound so good! 

 

How do you check the gearbox oil level? Going to have a look at that..

remove the undertray, and you will see a big grub type bolt on the left side near the back of the box, need a allen key for it, and with the car running in park and level, undo the bolt slowly and remove if no fluid is coming out, then try adding oil until it starts trickling out, if it doesn't need any the you probably need a mechatronic rebuild at about £500

FCUK FCUK FCUK!

 

Sorry i'm annoyed! :/ is it worth the repair? I have read that even with transmission rebuilds its not always a 100% success. Considering the cost of the rebuild as well I do not want to risk loosing out so much!

Take it to a transmission specialist for their opinion.

 

A service would cost £300-£400. A reconditioned box is anywhere from £2000 to just over £3000.  That's your box removed and all the internals replaced with reconditioned parts or your own boxes serviceable parts.

 

On the oldest E60s you are looking at basically their trade in value to fix a box.

Thanks for the reply guys,

 

Any recommendation for a good transmission specialist around Lancashire/Manchester area?

 

Is the car safe to drive? I have cleared the code and reset the gearbox, it seems to drive normal at the moment but don't wanna do any damage?
