MK7 TSI High Vehicle Power Consumption

[Clinton]

Has anyone copped vehicle power consumption is high on their car? I previously disabled stop start on my vehicle via obdeleven via apps i turned it back on but getting this error. Battery is a newish AGM battery and I've also charged it.

My car is a tsi 2013 highline. I do not have a start/stop voltage limit option in my obdeleven options. The only changes under 19 gateway in obdelven that I've made is changing battery type to fleece/changing the serial number when changing battery.

Thanks

Well should be doable as I turned it off easily in a 2019 Tiguan which is basically the same thing


Stop Start Disable

Control Unit 19

Code 20103

Adaptation

Start Stop Limit Voltage
VALUE Change from 7.8 to 12.0

You arent by some mischance using a god forsaken devils spawn Iphone are you. If so get a cheap Android phone like an old s6 that works properly.. Always remember Apples go bad after 4 days

Clinton: Hi.

I assume that you mean the circled first line in the screenshot below:



If so, don't worry about the message. Nothing is actually "wrong" in the sense that this message means some form of engine fault. The message is simply informing the driver that Start Stop (SS) was not enabled because one of the many prerequisites for activation was NOT satisfied.

Early release Aussie mk7s, like this car did NOT have the Start Stop Limit Voltage channel in the Gateway module as indicated in Hillbilly reply.

So, I suspect that instead, the OBD11 OCA (One-Click-App) used what's called the "Temperature method" (and NOT the "Voltage method") to disable SS. Incidentally, I suggest that you do NOT use OCAs - because they make unknown changes to the car's coding that are difficult to find if the tweak goes pear-shape (I NEVER use OCAs)

The "Temperature method" works ostensibly in the same way as the "Voltage method" in that both change the threshold values at which the SS algorithm refuses to enable the function.

To explain - the tweak change results in the following instructions to the SS algorithm

• In the Voltage-method, the change instructs the SS Algorithm to not enable SS if the reference voltage (which is NOT battery volts) is below 12.1 Volts. The factory threshold was 7.6 Volt before the tweak change!
• In the Temperature-method, the tweak change means - do not enable SS if the engine temperature is above -50°C (which is almost never). The factory threshold was +50°C before the tweak change!

So, I hope that you can see that the "vehicle power consumption is high" message would have been worth noticing without the SS tweak - because it would have indicated a possible problem if the message was consistently appearing. However, with the changed threshold values, the message is a permanent consequence of the tweak.

In fact, if the message did NOT appear permanently after the SS tweak was implemented, it means ironically that the SS algorithm is NOT operating correctly!!

Hope my words above make sense - if not, my apology for adding to your confusion.
Again, I suggest that you simply ignore the message and instead worry about global warming!!

Thanks for the reply, so i checked and my temperature one is at -50 -50 so it's not that. I used the OCA then undid the OCA however yeah it's still saying high power consumption. My goal is to have SS work again so not sure with the OCA tweak undone why it's not working.

Clinton: Hi

As I said, I NEVER use OCAs for exactly this reason (OCA's don't disclose the changes that they make). I guess that for those that do use OCAs, the omission is acceptable if the OCA is successful - but it becomes a real problem when (not "if") the OCA doesn't work as expected, as you have found in this case

So, bottom-line = using OCAs is a gamble IMO. Yes, they are easy and quick to implement -but you take a risk and sometimes you lose!! And as with ALL gambling - the more OCAs you use- the greater the risk of loss!!

OK - rant over !! The third method for disabling SS is to change the long-code string on the hex19 module - see HERE. The instructions in the link are for VCDS - but the change to Byte 03 is the same in OBD11 speak!
