Guys,

I need help with the following error 5FB4 "energy saving mode active"

I've been playing with air suspention settings and maybe did something wrong by accident but the error in question showed-up and it can't be deleted no matter what!
The car was in production mode with no such error and now no matter in what mode it is except en.saving mode error appears!

In another forum it was suggested tha I have to switch suspension modes to transport or parking and back to production but this had no affect the error still appears!

Am I doing something wrong or what?

Cheers

 

I don't want to speak too soon, but I think I have just cured a similar problem with mine. My problems started when i replaced the EHC after the old one got wet. I think I had the new one working at one point, but then it got stuck like yours appears to have. No matter what I did I couldn't get rid of the error. I'd never managed to get the activation sequence to run, it would always error saying "right side N.O.K" but I never worked why. I could manually raise and lower each side with INPA connected so knew everything was functioning, but it kept failing the activation routine (in INPA). Try reseting the module in INPA, recalibrating and then running the activation (all from the menus in INPA). I only got mine to activate yesterday, so I may find the error returns, but fingers crossed.
