Tunnels break logging consumption and speed
Seems more recent versions of ABRP is broken when driving through tunnels. My logs show 0 speed and consumption at way over 100k Wh/km.
This in turn has completely broken the reference consumption calculation.
- Where does this happen?
- ABRP version number (found at bottom of settings menu)

Thanks for reporting! We have just corrected an issue in ABRP where we would interpret made-up positions from the phone as valid - it will come out with 5.7.3 this week. That may solve your problem.
Otherwise, if you can, enable the “Show bug button” option in settings and press the bug button on the map when you are having issues and we get a detailed report which helps us find the issue.

Not quite sure when you want me to press the button. Is it when ABRP looses the track after a few seconds in a longer tunnel?
The bug is only really visible in my logs after the leg between chargers is completed.
Picture is from a roughly 165km drive:

Edit:
Not sure what is going on with plan links. It is not working for me here when using it.
Anyway the trip is from Ål supercharger to Voss handelshus super charger in Norway.

Thanks Jan! It seems like the root cause is that we calculate your driven distance entirely wrong in My Drives. We are looking into it asap and will let you know.

Part of the problem is that the logged track is just a mess after GPS signal is lost.
The picture below is from here:

Basically driving through some of the longest tunnels in the world in June 2024

Haha, yes, that is probably your phone or car reverting to dead reckoning when GPS is lost and reporting it as GPS location. We try to filter out such made up locations but found a bug in that handling just last week, and a fix will be released in ABRP 5.7.3.

The cars built in GPS never do this though. It just stays on the road and will pause at end of tunnel if I drive slower than expected.

Looks like my logs are fixed. But what about my calculated reference consumption? It keeps climbing slowly. Its at 202 Wh/km with a confidence % of 72 86 and 70. That is just insane for an e-Golf.
My longer drives in winter are usually 135-160Wh/km so why is the reference going up?
ABRP is basically getting worse at calculating as time goes by.

I’m thinking this might even be part of my problem with wrong consumption figures I’ve had since the start in my e-Golf. I drive in an area with a lot of tunnels and the calculated reference consumption and consumption at lower speeds is far from correct.
I’ve reported this issue before and been in contact via email, but nothing has been done.
