Hi
Just got my stilo back from the garge after having a new ecu fitted! It was running fine until it lost all power, the dashboard lit up and ASR failure and loose connection warnings came on the dashboard! Any help would be very apprechiated!
Cheers

Sounds like you need to get the garage to finish the job properly.

sounds like you need it towed back to the garage!
