Transmis Error Visit Workshop
Same problem here - will not move or change until turn ignition off and on again, happened yesterday evening, was fine 60 miles to work and back and then went 2 x times again this evening. Seems to happen when at a standstill, engaged and holding on brake. Is a semi auto sequetronic, am trying it now shifting manually to see if the fault is related to auto??

[QUOTE=W203E35;4468834]Let's take a look at these codes.
P2080 - The Pressure in the hydraulic system is too low.
P2081 - Pressure buildup by the hydraulic pump in the system is not possible.
P2080:
-Check hydraulic connection lines to the hydraulic control unit for blockage.
-If there is no blockage in the hydraulic connection lines, then replace the hydraulic pump.
-Replace component B56 (Sprintshift pressure sensor).
P2081:
For this code we have 2 options. We must start up the hydraulic pump and see if it's audible.
Is it Audible?? YES
-Check oil level in system SEQ, adjust to correct level if necessary as specified in repair instructions.
-Check the hydraulic connection lines to the hydraulic control unit for blockage.
-If there is no blockage in the hydraulic connection lines, then replace the hydraulic pump.
Is it Audible? NO
-Check fuse "F58" in component N10/1 (Front SAM control unit with fuse relay module) for tight installation and corrosion.
-Check lines from component N10/1 (Front SAM control unit with fuse relay module) to component M46 (ASG hydraulic pump).
-Replace component M46 (ASG hydraulic pump).
There is also something called a Pressure Reservoir. DAS doesn't mention this but this looks pretty important.
What do you think Glyn?
The errors all have to do with pressure and everything has been changed except this pressure related contraption
Can replacing the entire box be the solution to all these mishap?
