• Hello, I'm new to the forum and would like to know if anyone on here can list the main engine parameters (temperatures, Etc.) that inhibit the engine from shutting down when the car is stationary. The service manager at the dealership I got the car from was not especially helpful. I get a status message on the Amundsen display " high power consumption" when the engine will not shutdown, even though there was nothing (Aircon, Etc. switched on)  which the workshop diagnosed as a low output alternator and replaced. I am still getting the "high power consumption" status message when the engine will not shutdown, and I'm beginning to suspect that it might actually be the oil temperature that's holding it off. Problem is, I sometimes get an engine stop when the oil temp is just on 60deg. at other times it won't operate until the oil temp is over 80deg. Only a minor annoyance but any suggestions welcomed.

Car is MY16 Octavia TSI 1.4, 6 speed manual. Warrior193  

The engine will not stop if the engine temperature is below 22 deg C. That is watertemperature not oil.

It will not stop if the AC is on full cooling, or if the battery voltage is to low.

 

My brother had the same status message in his Audi A4, and after that both battery and alternator was replaced, they find the actual problem being a "voltage regulator modul".

To save fuel the charging voltage is low until otherwise needed.

My SE L 2.0TDi DSG stops every time I move from the drive 5 yards to the gate into the road if I don't forget to de-activate it regardless of the engine temperature.

 

I wish I could opt into start/stop rather than opt out as I don't want to disable it with VCDS; but perhaps I should.

Hi Norsko, engine coolant was above 60deg C, so it just may be the voltage regulator - thanks for the tip.

Agree with Norsko & yMe.

If stopStart is not available due to engine temperature conditions I believe it will display a different message "Engine must be Runing".

 

If yours is still saying "High Power consumption" I would suspect the battery or Battery Monitoring Module is faulty.

 

My car will also auto-stop after 100m from my garage in ambient températures above 10°.

 

 

Unless..... Do you leave anything plugged into the 12v sockets overnight like a DashCam or heater?

This will also trigger the "High Power Consumption" warning as the battey monitoring module detects that the battery state of charge has dropped more than expected while the vehicle should be off.

Hi Gabbo, thanks for your comment - I do have a dash cam but don't leave it plugged in overnight. I suspect that you may right about the module / battery. When this message first started to appear in the vehicle status, I did experiment by unplugging the camera during trips, but it made no difference. The problem seemed to be worse when the ambient temperatures took a dive recently - perhaps that does indicate the battery, because they do have reduced charge available at lower temps.

I have had this message "high power consumption" as well, and the start/stop was not working. It turned out to be a faulty battery, it was replaced under warranty.

The stop / start system is quite a complicated process with a varying number of influences...

 

Conditions for the automatic engine shut down (stop phase):

 

› The gearshift lever is in Neutral.

› The clutch pedal is not depressed.

› The driver has fastened the seat belt.

› The driver's door is closed.

› The bonnet is closed.

› The vehicle is at a standstill.

› The engine is at operating temperature.

› The charge state of the vehicle battery is sufficient.

› The stationary vehicle is not on a steep slope or a steep downhill section.

› The engine speed is less than 1200 1/min.

› The temperature of the vehicle battery is not too low or too high.

› There is sufficient pressure in the braking system.

› The difference between the outdoor- and the set temperature in the interior is not too great.

› The vehicle speed since the last time the engine was switched off was greater than 3 km/h.

› The front wheels are not turned excessively (the steering angle is less than 3/4 of a steering wheel revolution).

 

Conditions for an automatic restart (start phase):

 

› The clutch is depressed.

› The max./min. temperature is set.

› The Defrost function for the windshield is switched on.

› A high blower stage has been selected.

› The START STOP button is pressed.

 

Conditions for an automatic restart without driver intervention:

 

› The vehicle moves at a speed of more than 3 km/h.

› The difference between the outdoor- and the set temperature in the interior is too great.

› The charge state of the vehicle battery is not sufficient.

› There is insufficient pressure in the braking system.

Hi Silver, great, thanks for the list of conditions required for an engine stop - a lot more information than the service manager was able to give!

All those conditions appear to be ok when I'm getting this "Power Consumption is High" status message and the engine stop is not permitted. It looks as if it may be a battery or a battery monitor module causing this. Ho - Hum, back to the dealer. Again.

I have noticed also that if in the stop phase you try to turn the wheel the engine auto restarts.

Hello all,

 

Have the same problem with my Octavia 3 FL, stops after the first km, doesn`t take into consideration the water temperature, the temperature set on the AC, nothing.

In December i have changed the battery under waranty because the car stopped in the town and didn`t want to start and move an inch, they concluded that the battery

was the problem. After changing the battery is still doing the same, but, the only thing that changed is that the high consumption message disappeared.

 

The dealership excuse is that I don`t have any faults when they put it on the computer... it is just silly. I don`t know what to do anymore. It was ok during winter because you have heat from the engine, 

but, during summer it stops my AC from running regardless of the difference of temperature from inside to out.

My stop start did not seem to work with same message about high consumption. I was about to ring delearship but then went on a long journey and it started working. It now works on longer journeys.

 

Do you do alot of short trips?

I do around 700 km a week, from which, 4 trips are around 130 km each
