U1101Component protection active

• Volkswagen group code · Instrument cluster

How the car detects it

VW's component protection (the anti-theft pairing of modules to one car) is active, so a module restricts its functions or stays silent on the network. It is cleared online by a dealer after a module change; Audi also found sporadic cases fixed by software.

What you may notice

• A system (radio, parking aid, ...) not working
• Check-engine light possible as a side effect

Likely causes

• LikelyModule replaced or swapped without online component-protection removal
• RareModule software
