My 2004 Stilo JTD 8v recently brought up the error code C1121 and is now constantly flashing up Engine EBD failure, Stop engine.
It drives fine, starts firrst time and stops fine!
Any help would be greatly appreciated

Mine did the same thing after not being used for a while due to the recent crap weather.Its just a long shot,but have a forage around in your battery box (Remove the plastic cover for the battery).

Check all the connections,especially battery terminals,and make sure its all dry (fuses etc).The battery on the stilo has to be in A1 condition as well,or you get all sorts coming up on the OBC.

Hope you crack it.
