Skoda Yeti Fault Memory Lock Active

Alright, I'm getting annoyed. My 2011 Skoda Yeti with a gasoline engine is throwing a 'Fault memory lock active' error. It's got about 90998 km on it. The error is stored in the error memory. Could this be an undervoltage problem or something more serious with the computer system?

Whoa, a memory lock issue? Sounds like your Skoda's computer is having a bad day. Is the car driving any differently? Maybe try checking your battery connections. Are they clean and tight?

How would I check for undervoltage myself? I have a multimeter, but I'm not really sure what readings I should be looking for on the ECU.

Yeah, undervoltage can cause all sorts of weird issues with the ECU and trigger that active memory lock. Honestly, messing with the ECU without proper Automotive diagnostics tools can be risky. I’d suggest getting it checked out by a professional. They can properly diagnose the Computer system and clear the memory lock.

I took it to a shop, and it turned out to be undervoltage like you thought. They cleared the fault memory lock and checked the battery. Cost me 240€ but at least it's sorted.
