Mercedes Viano W639, 2014, 2.2 cdi
I've had this exact same thing. It's the ESP ECU module failing. I had to have a second hand ECU reprogrammed from an E Class but you can find a Viano second hand for about £700.
Mine failed as I was exiting Hale Beach near St Ives in Cornwall. If it fails completely like mine did the whole ECU network shuts down and the van is locked in park. If that happens there is a switch inside the Gear Selector housing, you'll need to break the clips holding the cover tight and slide the cover up the gear selector knob. I wasn't aware of this so had to have my Viano SLID onto a recovery lorry.

These guys diagnosed and fixed it with ease, I highly recommend them, even if it's only for a phone call.
