Start button not always working

[Mike in Anchorage]

I have a TDI, which requires the glowplug to warm before a start sequence is initiated. One push and the screen shows "engine starting" which may take up to three seconds before the starter engages. No need to hold the button down. As with the others, I suspect an interface glitch that is not related to the fob. My fob gets cold [yeah, you can play with that statement] and sometimes doesn't link right away. The dash indicates there is not a correct key within the correct distance. Hope this helps.

Push button start is the worst. I had a 3 series with it. At least in that car you still inserted the fob.

I rented a car that had a start button but no place to put the key. I was always looking for the damn key.

“I know I have the key because I got in the damn car now where did I put the thing, I have to lock this Mazda or Nissan or whatever this rental is”

Hmm interesting info.
My '15 GTI S does not have push button start but the wife has a '17 Tiguan and the push button start drives me crazy!
Like others have mentioned, in other cars you can just quickly push it down and the car will fire up.
But in the VW you actually have to hold it until the motor actually fires up!
Half the time it wont even start the first time and I have to push it down a second time.

ummmm.....why don't you just leave it in your pocket?

Dunno why you'd ever take it out in the first place, let alone wonder where to put it.

I've *never* done this in my R - just a quick press, and the car cranks over as long as it needs to and it starts. Every time.

Yup. This.

You clearly don’t spend half your waking hours looking for your phone keys or wallet. Sickness is the answer.

Interesting.

I have been getting a Keyless Access Faulty error message occasionally...

My start button was also sticking (not starting) and replaced under warranty

Me too - new one was huge improvement

Me too. Replaced fob batteries just for the helluvit since they were 18 months old, didn't expect it to cure this, and it hasn't. Very sporadic. Hasn't happened in a few days now.

Anyone ever figure this out?

I believe the problem lies in the contact point inside the button
One of the solution is to remove and disassemble the button, clean the contact point using plastic safe electronic contact cleaner
The other is to replace the button

There's a discussion on it here - https://www.golfmk7.com/forums/inde...emove-replace-start-stop-switch.357251/page-2

Old thread that I see I responded in so I guess I can update.
Dealer ended up replacing the whole button assembly in my wife's old Tiguan.
