Hi I have a e90 318i that's got a issue,car gives code cc-id 207 (central electronics failure) the issue goes away if I disconnect battery and reconnect but after a few days/weeks it happens again. Speedo doesn't work, wipers, central locking, steering heavy and takes longer to start. Any1 know what could be causing it.
Thanks

I've got this exact issue, check the voltage across the jump start points in the engine bay. Mine hits 15.7v when the engine is running which is too high and likely a voltage regulator failure causing the modules to shut down and throw multiple warning lights. I have a new regulator arriving this week so I'll let you know of it solves things.
