Hi would really like to know how you ended up as have similar problem on my lr4.... I keep trying to signup and russian site wont let me in???

 

You need to fix Gear sensor BMW 6HPTCU inside you gear box.

 

Did you fix it? I select drive and gearbox fault goes on! And scan tool says P081C-64 2010 LR4

 

Good day, not yet my car is with Land rover since Friday last week they are still trying to find the root couse of the fault.
Below is the responce I got here on the forum it was in Russian I used google translate. Hope it helps.

Well, I won this thing !!! Hurray again on wheels!
A small report.
As a result of the diagnosis, the electronic board mechatronics was sentenced.
It so happened that I have a Continental (Simens) board, it is just not famous for its reliability.
In fact, the following occurred due to govnopripya, contacts begin to disappear over time.
In my case, the hall sensors (A1120) of the smd mounting just fell off. Which are in a brown plate.
By the way, the box is so well-known and put on a wide range of cars, then the problem is also not the first day.
In this case, there is such a thing as the BMW 6HPTCU Gear sensor, the board itself.
I gave the guys who have equipment, they opened everything and soldered and diagnosed everything, for which I thank them!
if anyone needs to write here, I’ll give a phone number.
In general, during the repair I had the impression that people simply shamelessly untwist on services. They suggested changing FULLY MECHATRONICS !!! there were prices 208k 160k, a representative of ZF offered for 68k but this is not a new pancake !!
So keep your tail with a gun !!!
Even the same LR Ligovsky in St. Petersburg.

Well, some pictures.

Good day, how do I fix it, can I replace it?

 

ok, i will explain
Usually its happened with a mechatronic electronic Continental (Simens) PCB (printed circuit board). Other - Bosh work very well.
Main error its broken contact in hall sensor. In my situation just departed from PCB.
You just need put back it on PCB :-) In my situation i found service company that a fixed this for me.
Also you can check all other parts in mechatronic and gearbox, like oil, solenoid, and more :-)
some photo is bellow




This is PCB and Hall sensor!!!!

 

Wow im impressed at how far you've gone with this...Im just a little confused on if you repaired or replaced more than 1 circuit board? But great effort!!! Cheers Greg Nostrovia!!!

 

My mechatronics is a Bosch see picture and doesnt have that extended tab.

2010 LR4 TDV6 2.7
