Gearbox Fault - Select Park Before Engine Stop

Hi,

Further to my post yesterday regarding replacement part numbers, here is the situation surrounding it, incase anyone wants to chime in and let me know their thoughts. I have read every post on here and on two other forums related to the above error, but i'm still no closer to figuring out what is going on.

According to previous owner, this fault came up after a dead battery. I bought the car, fitted a new sealed battery, but still the error comes up. It is temperamental, and will be on all morning, and all evening, but seems to go off my itself for a while during midday.

I had a battery and alternator test done at the Bosch agents here, and have attached the report. Also checked the Rear View Camera Connectors for water, but nothing visible. May try disconnecting the rear camera completely to see if that does anything as @Cutter7 reported that his camera had caused the same problem...

Did a scan on SDD and it says:

U0101-87 GSMB Lost Communication with TCM: - Missing Message
U0404-82 GSMB Invalid Data received from Gear Shift Module A - Alive/sequence counter incorrect, not updated
U0103-87 GSMB Lost communications with Gear Shift Module A - Missing Message
P1794-92 Battery Voltage Circuit - Performance or incorrect operation


Hoping someone can point me in the right direction, that flashing yellow triangle on the dash is driving me crazy...

Br,
Owen

Have you had any software updates recently? My Evoque went in for its 4 year service this week and they updated the software, and I now get this message. They've checked the gearbox and say its find, but they need to apply a "fix" from JLR to clear the message. Going back in next week for the update.

Hi Dave, just managed to figure out that Battery Drainage is causing mine. In the morning when voltage is at 12.3V i get the Gearbox Fault, but once the car warms up and has been driven, voltage goes above 12.4V and the Gearbox Fault warning disappears.

Now trying to figure out whats draining my battery down to 12.3V overnight, but i am suspecting it to be a hidden tracking device from the previous owner in South Africa... the internal battery dies and it proceeds to chew the Evoque battery instead!

try an optimate on it at night, that will prove it,

Steve

I'm having a similar issue on my MY12 Coupe

What year is yours?

Mine is a MY12 5-door...

I was told that new batteries have to be logged into the cars computer so it knows which algorithm to apply when its measuring its condition.

Anyone heard of this before?

Hi Wavey Dave,

Any news on the "fix" from JLR to clear the message? Or is there a TSB Number for it? I've also been told by Land Rover South Africa that the gearbox is fine, but being in Malawi, theres not much i can do. I've been on the phone all day to Land Rover in South Africa, Zambia, and Zimbabwe, and still cannot get anyone to fly out here (at my cost) to sort it out.. The old Land Rover dealers here have SDD, but they don't know how to search for such updates and fixes (hence why they lost their Land Rover licence!)

I am being told now that I have a faulty gearbox ecu (sits under the gear knob apparently) and that has been draining the battery.

Strangely there are no fault codes being generated by this which is why it is hard to diagnose?

Inconveniently for me I have discovered the problem two months after the warranty ran out although I suspect it has been there for a while as I had to have a new battery in May 2016.

Hi Mcbrid,

Have they told you which module? The gearshifter itself is one module, and it connects to another module on the gearbox that actuates your gear selection... would be interesting to know the Part Number so i can plan to buy it just in case - i'm 2,400km away from the nearest Land Rover centre so i have to plan everything in advance!

Strangely on mine, if i start the car the error comes up on the display, but if i switch the car off and back on again, its gone... So i play this game all day so as not to see the yellow triangle and the warning...

Had mine on SDD today and did the 'Gearshift Position Learn' and the 'Gear Sensor Calibration' done, but still had the error pop up...
