Auris HSD 2014 idle consumption

[floHsd]

Hi guys !

I recently started to notice something weird with my 2014 AURIS HSD.When starting the car at idle my consumption skyrokets.It's like 2.05 l/h or 99.9 L/100Km.This happens when the ICE is running even if the engine is cold or warm and regenerating batteries.

Weird enough I still get good mileage but don't know if this is normal

Is this normal?

They all do that, sir. A cold engine is one part of the reason! (A lot of energy goes into warming it up.) And another is that the fuel mix is much richer on start-up. My 1.6 petrol hangs onto high(ish) revs while on the overrun during gear changes, until the engine's warmed up and the torque curve is a bit more hefty. Then it settles down. ISTR recall Clarkson getting 1 mile per gallon from some American monster during its first half-mile? Same thing.

From your pic, I'm guessing you've never had a car with a manual choke?

I did once have an electronics issue with a Citroen Xantia where the fuel mix from the automatic choke wasn't well graduated. If you started that car, ran it for two minutes and then stopped it, you'd never get it started again. Well, not without a struggle.

If you are not moving, then the software that calculates fuel consumption, doesn't have the parameter from how fast you are travelling. It probably just defaults to the maximum reading on the display, until you start driving and has all the required data.

LOL, ain't that the truth?  At zero mph, even a tiny sip of fuel puts your theoretical mpg into infinity. I was assuming that the OP had ruled out that factor

In practice, the display will usually calculate an mpg average based on your last 30/60/120 seconds of movement. (Or longer. I don't know the time on this car.) Any time I reset the trip in my 1.6, I'm looking at 5 mpg for the first few hundred yards until it sorts itself out. And a proper average figure doesn't emerge for a few miles.

Either way, if Florian's car is starting and running OK, it's unlikely that there's a problem.

Thanks for all you're answers!

Don't let that picture trick you I am much older then I look :))))

The thing is that all my other cars never displayed more then 0.8-0.9 l/h when stationary.

Anyway I sort of figured out.

When the HSD Battery is regenerating I get 2.7-2.9 l/h but If I let the car in Neutral I get a normal consumption of 0.7 l/h 

Do you guys get the same consumption when regenerating on you're hybrids?

Yeah, that's one of the things I don't like about HSD. All the refinement that one would expect from a petrol and especially hybrid goes out the window when the engine kicks in when stationary to either charge up batteries or to speed up the warm up process (which also charges batteries). Typical 4cyl petrol engine is virtually inaudible when idling at tickover. HSD revs up on purpose making more racket than the nastiest 1.9 TDI engine.

Interesting post. My Auris consumption is very high at cold in the first minutes. Here a screenshot of hybrid assistant. Hybrid system on for 3:15. Ice on for 3:00min. 140 ml used. Can you test if you have the same consumption ?

I did the test at idle. It is very hard to have a good average on short trips with as much consumption from the start.
