Strange Automatic transmission issues
Discussion
Hi All 2010 X1 S-drive with 2.0petrol engine.
Ran this car with no issues at all, then had it sat in my garage for a month as i had purchased a new car.
Advertised the car and someone came to test drive her about 10days ago - She drove faultlessly and they decided to buy the car.
A week later (Sunday 10th) they came back to collect the car and within 500meters the car developed a whole heap of transmission related issues.
The only thing that had changed from test drive to purchase - was that i had attached a battery conditioner.
I gave them their money back and limped the car home (it was jerking in and out of gears and then would run ok, then jerk in and out of gears - and when in park the gear selector 'trigger' would click rapidly on and off.
This morning I thought i would have a look at the car and when i started her there were even more issues.... It went something like this:
Car started with a missfire (which soon cleared)
the revs would hunt (dip) as the trigger for the gear selector would again rapidly start clicking. If i sat with my foot on the brake and changed from Park to N or R or D the selector would continue to click - every time it did so the revs would dip and the indicator would flash from D to P (or R to P is i was in reverse).
Then (still whilst in the garage and with the car in park) the car seemed to run fine all of a sudden (no clicking from the selector or revs dipping) but then the Traction control light came on and then the brake warning light came on and then the gearbox issue resumed.
I have basic Carly scanner and i am now displaying the following codes:
003099 - CAN message EGS missing
00A3AA - Error failure transmission data CAN ID 1D2 error
00578E - Transmission fluid deteriorate: This one has been on the car for months and on Sunday when the issues started, was the only code showing.
00D258 - Transmission data not received (received by DSC control unit)
00277D - Misfiring (cylinder 2) - which cleared.
Anyone had a similar series of events?

Modern cars hate not being driven and dodgy batteries.
Disconnect the battery, check it's fully charged (if you only have a trickle charger and the battery isn't great it will never fully charge the battery). Leave the battery disconnected for a few minutes before reconnecting. Then see what's happening?
The transmission fluid condition warning is a bit of a worry though.

Has this got the same 8 speed auto as the JCW(transverse front wheel drive installation) . These boxes seem to have started giving problems recently will try and find link and add to thread.

Hi all, and thank you for your replies....
To answer some of the questions: The car is running the N46 2.0i with the ZF 6HP gearbox. She has covered 83.000miles (134.000km) and whilst there are a lot of service stamps in the book, there are hardly any invoices - so I cant actually confirm if the gearbox fluids and filter have been changed. The battery is a genuine BMW battery but again i don't know how old it is.
So far i have attempted a gearbox reset by holding the pedal down for 30seconds whilst having the ignition accessory 2 position - Nothing changed. I have disconnected the battery for 12 hours and worked my way through the fuses that relate to the issues.
Someone mentioned to me that the initial misfire (that clears) could be the source of all the other issues ??? As opposed to a symptom of the other issues ??
This weekend I will put the car on axle stands and check the gearbox fluid level - If its low i will top up and see if that improves things and i might swap the coils around and see if the misfire changes from cylinder 2 to a new cylinder - And if so i will purchase a new coil pack and see if that helps.
After that i will resort to finding a BMW specialist (easier said than done where i live) - I a, currently residing in South Australia.
