We had this same issue code came back to brake pressure sensor which a new one didn’t fix, traced wires back to under seat on our 25e and the steering pressure sensor was faulty which was stopping it engaging gear hope this helps

Thanks. I’ve got a steering pressure fault that I didn’t consider relevant to not acknowledging that the hand brake had been released!

It was under the seat on our 25 I’d try that as that’s what sorted ours

More than just the sensor! The wires had melted. Thanks for your advice.

Glad you found it was it the one under the seat?

For me ma4604 is dumping air when park brake is released. Than I wasn’t getting air past se5501. Found a blown fuse for park brake and replaced it. Now I’m back to ma4604 dumping air but the park brake is released
