Does the golf r have a button to turn off the stop/start function like the gti?
Cheers.
-
Yip
-
The soft touch button is standard with stop/start
-
Thanks for that lads

Why would you want to turn it off?
In a manual car it won't stop unless you come to complete stop and take it out of gear and in a DSG unless you jump on the brakes to stop Hill Hold will activate and leave the engine running so it sort of makes the button redundant :huh:

You turn it off for every scenario other than the 2 you haven't listed. Its a stupid device imo and the first thing i turn off when getting into the car.

I like it, it's easy to work with and I only ever switch it off if I'm needing a quick start at a junction or roundabout.

I like it on the manual cars, if you think the lights are about to go green or waiting at a roundabout or junction for a gap to get on it, you keep the clutch dipped, and if you've just missed a set and have a wait, you let it kick in. More intrusive on the DSG without a feather touch on the brakes when coming to a stop (not always possible, depending on what conditions ahead are doing).

I was unsure about stop/start but I find it to be excellent, no issues. It seems to learn too as it used to cut in when I got to work and had to get out to swipe in to the carpark which was annoying but now it doesn't but does know if I stop 20ft further back because of someone in front! Very clever!

The stop/start facility should be stopped and started as little as possible to produce longevity for consumable parts. The starter, oil, oil pump, battery, engine components are all effected by the stop start process so the fewer amount of times this process activates the better for you engine. VW did not fit this device for the longevity of you engine, my guess is it was fitted purely for the emissions/MPG process. You do not want the oil pump and oil flow stopped and started constantly in any engine...

I agree with Jackie T's post on the effects on the engine, battery and starter motor.
I turn mine off as soon as I get in the car.
I like to think of it was a clever device fitted by VW to get the emissions and road tax down, but they wouldn't be that sneaky would they? :)
-
Wouldn't it affect the battery as well?

I wonder if there are various sensitivity settings on the amount of brake pressure applied as i definitely use more than a feather touch on mine and it very rarely cuts out.
When I tested a GTI with DSG before I bought my first Mk7 Golf I had decided within a couple of minutes that I was having a manual on my GTI. The DSG in that car was awful. Really sluggish and slow to respond and that one did cut the engine with a very light touch. My R with DSG is night and day different and in my opinion how it should work. It's so in obtrusive I hardly ever notice it and don't feel the need to reach for the off switch every time I get in it.

I was once told that for it to save fuel that the stop has to be longer than a minute, any less than that and it uses more fuel starting the car. I'm no expert and the person that told me that works test facility and seemed to know what he was saying. However as I said I'm no expert and he could have been bullsh!tting me.

It would be great if it could be turned off permanently using the touch screen.
I hate it in my wife's car which has the s tronic box.

The starter motor on stop-start enabled cars is beefed up, the battery is optimised for stop-start in the way it is charged and discharged, and on the R at least, the car is using an electric coolant over-run pump (V51) to stop the turbo bearings from overheating for a short while after the engine is turned off (there's a few R2D2 sounding noises and the low hum) - I'm quite sure the GTI engine (and all variants of the current 2.0TSI) has this but can't confirm it.
Stop-start won't kick in until the engine is sufficiently warm - VW have clearly considered the effects stop-start would have on a stone-cold engine, battery and starter motor (when the oil has thinned with warmth to not make restart effort as hard as the first start). By far the most engine wear occurs on the first cold start-up when the oil is not on the internal components of the engine after being sat for hours/overnight. If stop-start put a huge amount of wear on the engine and ancillaries, i'd expect to see a noticeable amount of metal in the oil filter at every oil change.
Stop start won't make VAG engines last half the miles they used to, considerations have been made in the design and utilisation of stop-start tech. I'm sure most of the other Marques did the same when they introduced stop-start.
Things have moved on in engine tech and lubrication tech since the 80s...

Has anyone got a photo of the button on the r because i cant find one.
Thanks again.

With thin fully synthetic oils and other recent tech (fuel priming etc.), it's supposed to be down to about 20 seconds now. On a car without stop-start tech it is somewhere between 40 seconds and a minute if someone simply switched the ignition off at a set of lights.
-
It's the button next to the driving mode selection button on the left side of the gear stick.
I dislike stop/start immensely and turn it off as a matter of course, just after buckling up and switching the ignition on. I'm adept at stopping it kicking in by just tapping the brake at standstill, but don't see the point when you can just switch it off and be fine with it. I like the other AIDS such as hill hold (genius) and the electronic handbrake etc, but not warmed to S/S at all.

Obviously it has moved on from the 80's thankfully :smiley:, although i wouldn't mind my R5GT Turbo or 205 gti back.
If by "beefed up batteries" you mean AGM batteries yes they are, starters have more KW and brushes too, but essentially that's it. Whether your oil is warm or not is irrelevant if you are stopping and starting 25 times on your way to work instead of once. The less times you stop and start a car the better essentially and i think that is universally agreed, and this feature was not designed to improve the longevity of the car. It appears it was designed for the EU test for emissions and this involved traffic simulation and 12 stop and starts, so if you cut the engine... voila!! I guess you get improved emissions and MPG. :whistle:
This surely was only to pass tests, and everything else, be it AGM or starter motors was simply to help that test and won't help the lubrication, imo.
I could be wrong and it could be a great invention to help, i just don't believe the info we are told is good for us.

I'm a 'poor relation' manual driver and find the stop start doesn't bother me a bit. Mind you I don't spend ages stuck in traffic as a rule.
If I owned a GTD then I'd probably love stop start. Nowt to do with the fuel savings (assuming there is a detectable saving), purely from the noise and vibration point of view.
Modern diesels are smooth on the move but still have a noticeable vibration at idle.

I think that the dislike of stop-start is dependent upon your commute/driving conditions and how much it kicks in on your car. For me as a manual driver, I like deciding when I will let the car stop, and there may be only 2 or 3 times on my commute that I am at a stop for any meaningful amount of time to allow it to kick in. Stop-start is by no means "good for your car", but considerations will have been made so it won't be susceptible to a premature death either.
Warm restart engine wear is accepted as tiny - it's the first cold start that does the damage when metal runs past metal with little or no lubrication on those parts as all the oil is back down towards the sump and the oil is at its most viscous. An oil pump pumping thinned/warm oil after a stop-star restart won't be under a huge amount of strain either, and stop-start won't stop a stone cold engine.
