Thanks for the tip Travs. I will do that in future.

MikkyTee - wouldn't it be easier just to switch off the start stop system using the switch next to the gear lever?

Yeah i know but i keep forgetting and the dam engine shuts off when i least expect it. Drives me mad.

Hi,

I've done this modification on my Mk3 almost from the beginning. Though I didn't disable completely the S&S.

Factory setting of start limit voltage is 7.6V.

I've pushed it to 9.0V So that it doesn't kick in too often. (This value is just a question of 'taste').

If it's set to 12.0V, then S&S is completely disabled.

I've lurked for years on Audi and Skoda forums, I've never read someone reporting problems related to S&S disabled using this method.

I plan to do the same on my current Kodiaq Mk1

However Im' curious to know, what makes you think it's not a great idea. Feel free to explain. I may have missed some point.

TIA

It depends on the mod to fool the battery charging level, @Bap33 .

There's a mod where a sensor is physically disconnected, which is the mod I was thinking of.

@MikkyTee wasn't specific about which mod he was referring to and didn't mention VCDS, so I feel my note of caution about the simple bodge solution was appropriate.

If Mikky intends to use VCDS to tells the CPU that the battery isn't in a condition suitable for S/S, then assuming that changed voltage reference is ONLY used to permit/inhibit S/S, then that sounds fine to me. 👍

I’ve tested this a fair bit over the past 10 years and for me personally it makes so little difference on my usual routes as to be not worth doing.

On longer holiday motorway runs the cars doing 40+mpg so not worth using it.

As per @Ootohere, I also live in a hilly area (in the Pennines) and it is second nature for me to tap the throttle to enter coasting mode the millisecond I have crested a brow, to coast down the other side.

I know my area like the back of my hand, and if I enter coasting at the right time and in the right place I can be coasting literally for miles before any form of intervention, i. e. braking or acceleration, is needed. I'd defy anyone to tell me I am not saving fuel by doing this, you don't even need to look at mpg comparisons to know it, it's obvious.

The one thing I don't quite get from the OP from @Pooroldcodger is that you say it entered coasting while motorway cruising. Was this under manual control using the pedal and you'd taken your foot off the pedal, or other? Just that you can't enter coasting mode while using cruise control. Just curious.

And on the other discussion about coasting while going downhill with a severe gradient and bends...mine both will and won't go into coasting, when I tap the throttle. On the same stretches of road time and time again it is baffling as sometimes the car will let me go into coasting, other times it flat refuses and insists on putting itself into a gear that is always far too low for the speed I'm doing - at which point I go manual.

Nice little win on the way down - but, like me, you pay when coming back…….

I am sure that there has to be a saving travelling downhill.

Regarding Gax's question. I can't honestly remember with certainty if I had ACC on, but I would not just take my foot off the accelerator unless I was, so I think I must have been.

I was on the more northerly parts of the M6 which was quiet by today's standards, and cruising along and glanced down at the rev counter and realised it was showing idle speed and no gear number was indicated. At that point I touched the throttle and the revs and gear came back up to what I would have expected.

I am going on another motorway trip on Monday so I will check and see what's happening.

One thing I would say about the DSG box is that the changes are very smooth going up and down the box on a straight road, but when it comes to it selecting gears itself through traffic it does seem to select a lower gear than I would have done manually, and this can lead to a jerky ride. EG approaching a left turn off a major road on to a smaller road. I could certainly do the same journey , and pull up to a full stop smoother with a manual box. I know it is a very different technology with different pro's and cons, but the 20 year old ZF auto box in my Jag is incredibly smooth in its changes.

As to paying going up. Try an EV where you can see exactly what is gained. I often go up on route / road a direct why, shorter steeper climb but return the longer route with the same drop in elevation but more regenning / coasting. Generating power. Like cycling routes in a circular manner really, anti clockwise or clockwise, same journey different energy exerted. That can be measured easily e-biking. Power / assistance required. How much battery to you get home with or not.

The newer ZF conventional auto's can coast as well.

I didn't know that. Clever stuff!

Hi ,

I had 1970 Saab 96 V4 model and that car had a free wheel system that I used once and that was enough for me.

Not really sure if my 2019 Superb SEL Executive 1.5 Tsi DADA has such a system !

It has what I call the CV system when it runs on 2 cylinders ( seamless ) change.

Stop / Start 2 cylinders mode and coasting model may improve mpg but at what cost to breaking system.

Update on this subject from me.

I confirm the coasting only occurs when driving normally - not in Cruise control.

Now that I know it is happening I am less concerned about it.

Thanks for all the comments.

It doesn't... S/S and ACT/CoD is irrelevant to the braking system, and if you look, you'll notice that a coasting car shifts into gear when you apply the brakes.
