Engine Start/Stop Issue

Post by marksebj »

So I've been having this issue whenever I'm In traffic or at a light and my engine goes off because of the start/stop function. But the problem is during the start phase where the engine sometimes doesnt start back up when I'm about to pull away, it tries once or twice and sometimes doesn't start up and I have to manually turn the ignition off and restart the car.

What I do now is turn the start/stop function off to avoid this problem. But I need a permanent fix.

I have a 2014 2.0 TDi blue motion DSG if that helps.

Anyone else having a similar issue and know what the solution for this issue is?

If it's 2014 it's still under warranty, I'd have it back into VW and get them to sort it for free.

I was about to say the same thing, let VW have a look at it rather than ask a bunch of strangers on a forum, lol

Sometimes those "bunch of strangers on a forum" are more helpful than a "bunch of strangers at VW Dealership". ;)

I have mechanical breakdown cover and also the warranty on the car, I was going to take it in but I thought all of you guys would love to weigh in lol
And if it was a simple fix why send it to VW lol

This post says you may be able to code out stop / start with VCDS http://www.sciroccocentral.co.uk/forum/ ... 36&t=23500" onclick="window.open(this.href);return false;

I have the same issue and it's due to the flywheel 'deteriorated' according my the AA. [emoji19]

Im not sure it will work but i have that option in vcds.
But can't try it out because i don't have start stop.

The method I heard about was to set the voltage at which start/stop works via VCDS to above 14v. If the battery voltage is below the set voltage then the start/stop will not operate. Not tried it yet as I do not have access to VCDS that will work with a 2016 car.
