Hi all. My 2015 Octavia Greenline III (1.6 TDi 110 6spd) is reporting a couple of errors that suggest a possible sensor issue. I wondered if anyone had had similar and knows what I need to be replacing/cleaning. I searched the forums but couldn't find quite the same problem. 

 

During normal driving the car is reporting that the stop-start can't function because a) the engine isn't running and b) power consumption is high. Presumably the latter error is due to the fact that it doesn't know the engine is on so it assumes it's not getting the voltage it actually is. Any ideas whether this is fixable for sensible money? The car is nearly nine years old and has 120k on the clock, and I'm not in a position to chuck loads of cash at it beyond routine maintenance. Thanks for any advice. 

Hello, are you sure of the wording of your first report message (a)  Is the message actually 'Engine must be running' - which means that some function requires the engine to remain running.

Message (b) - 'Power consumption is high' usually means that battery voltage is too low to allow idle stop to operate.

Both messages together can be caused by a failing battery - have you had the battery tested?

Thanks for your response. That's an interesting interpretation, I didn't think of it that way. It *has* turned over slowly once or twice. I'll get the battery checked.
