Mb clk 320cdi 2006 Intermitted fault

[TomiDo]

Hi Guys, I get a bit confused with this.
The issues are the following,
When I start to drive the car, parking sensor going of, then when I stop, I can’t put to reverse or park. It stuck in D and N. But if I pump the brake few time, it’s release. The park tronic still not working and if I put to D again, then stuck again. If I turn the ignition off, the transmission always release.
The problem is intermitted, so sometimes work perfectly. I have this fault codes. B1050, 240C, P1856
It’s shows some signal issues from the key.
I did change the key to the spare one and it was good for a few hours, then today morning done it again.
Do any of you such a experience?
Thank you for any help.

Sounds more like gear selector problem. Modules gone bad, and physical linkages too.
