Hi All
New to this but have a ZFHP32 gearbox and was getting a solenoid mechanical jamming code 4e89. Did a fluid flush and filter change and also replaced mechatronic seals. The error remained and the engaging of gears wasn’t happening and looked to be due to solenoid 1 as kept closing and throwing other solenoids. Before the change of oil could still get 10 mins of driving out of the car before entering limp mode and misbehaving.
I then got the garage to swap the solenoids from solenoid one & 2 to EDS 3 &5 as the colours are the same. Once this was done 4e89 “mechanical jamming solenoid 1 or 2” code went and car drive perfect in lower gears but mechanic said when gave it a foot down treatment in high gears it misbehaved. Topped up the fluid and issue still persists as mechanic thought little low but now right.
4e89 code is gone since solenoid swapped but now have 0027ec and the car goes in limp mode in high gears and mechanic said feels like stuck in high gear and can’t change back to park or reverse. But if turn off car and restart again then fine in the gears. I would think that what was originally solenoid 1 now EDS 3 is the cause given that one is now a high gear solenoid per ZF drawings and controls 5th gear?
What does this 0027ec code mean as on DTC says DME & DME2 “No message, receiver DME, transmitter EGS” - could it be linked to dodgy solenoid or new issue?
EDS 3 & 5 I have ordered new solenoids but taking a while to come so wanted to hear some community views on the topic and obviously update when get to the bottom of this
Thanks in advance everyone!
