Well gents, managed to replace the solenoid unit after two scrap dealers had faulty ones one had a good one. Once I got the covers off replacing the unit was fine, had a couple of leaks but all good.
Car ran for three days with no issue 🤣 three days well chuffed, but then the fault came back sort of, the raise lower buttons did not go out this time so replaced the regulator arm on the front left and will take for a spin tomorrow to see how it goes
Up to now I have replaced two regulator arms, two regulator sensors and a solenoid unit, only the EHC11 to replace, let’s hope not

🙈
