Mercedes Vito Electric sliding door

[Lfabs]

Hello All,
Both electric doors stopped working in my 2009 Vito so I took off the door card on the drivers side and found the circuit board just rattling around in there. I took it out and saw some slight burn marks on it so looks like it may have shorted out. Otherside door is now working. Anyone found a replacement for the circuit board?

Viano/Vito (W639) Electric sliding doors - My fix

This is a post that I hope can help others as fixing electric sliding doors can be a bit of a black art.... Problem: Viano would not lock electric sliding rear doors or the boot. Dashboard error saying LHS door unlocked. Problem was intermittent (and would 'fix' itself with no intervention)...

dont know if you've already seen this post but this guy seems to have investigated a lot on these doors
