2015 GTI Start stop issue?

[Tobes_WIR35]

Ive found 95% of the time when the AC is on that stop/start automatically is disabled.

I would have thought that this would be the case too, however this has not been our experience so far. Stop Start seems to operate all the time irrespective of these conditions. The other day the car had been parked in the sun on a 32 degree day all day, my wife got in to drive home and from the very first time she stopped until she got home, stop-start was active the whole time. The AC system was up against it from the start given that the interior air temp was probably up near 40 degrees, couple that with heat gain from the 3pm sun and the fact that the compressor spent 20% of its time not working, meant she got home very sweaty! (yes she could have wound the windows down, but anyone here who's married knows full well that you don't try and make a rational point with an irrational and cranky wife).

I'd like to think VW engineers wouldn't have made such a critical error, but given recent events vis-a-vis emissions claims etc, I am not so sure... Maybe they needed that extra poofteenth of a percent lower fuel consumption to meet some ridiculous emissions standard somewhere... (sorry, just me being cynical and somewhat sarcastic...)

That aside, the Polo seems to be a great little car. Not as exciting to drive as the Golf, but an excellent and zippy city car.

i only use stop start button when i am in drive through (maccas), other than that never coz it play up the a/c and it could play up something else.

i notice the mk7 auto park brake is also have problem, whoever created this features dont think far ahead

Well my 2012 model Passat is now getting a new starter motor because of a start/stop failure.

Exhibit A of why start/stop is a silly idea. Just get it permanently disabled.

Is it possible??

I think so. The dealership can do it, but they might not want to for whatever reason. Otherwise, find someone with VCDS and ask them to do it for you.
I believe it's a fairly straightforward thing to do. See: Disable Stop/start - VCDS tweak

^^^^^ OR, if you don't access to a VCDS cable (or your friendly VW dealer acts obstreperously - which is not uncommon) and the Polo has a SS on/off switch on the centre console (like the mk7) and you are handy with a soldering iron, then you could build yourself an Automatic SS disabling switch!

I did, now SS on my mk7 automatically goes into the disable position every time I turn-on the ignition (5 seconds after ignition switch-on). I have complete freedom to leave SS disabled throughout the ride, or I can engage/re-disengage SS at any time in the trip. Much better than my VCDS tweak because there is no tell-tale indicator on the MFD whenever the car comes to a stop.

Works real well and it's easy to make and to install (even if I say so myself). Details HERE
