I've a 2015 Mazda 6 tourer 2.2d se-l nav, 27k.
Twice in the last week a warning message appeared saying "SCBS forward malfunction " and the engine cut out. First time the engine started up again immediately and the message disappeared. But the second time the engine refused to start, just kicked over once then cut out. Eventually after 10 minutes I was able to start the engine again, the warning message disappeared and everything was OK.
On both occasions I was driving slowly down a hill, in neutral with my foot on the break to control my speed.
Any ideas on what is causing this, or similar experiences would be greatly appreciated. Thank you.
