Disable Engine Auto Start/ Stop Feature

Great forum! Soon to be a new 2018 Golf R owner. I noticed that the new 2018 Golf has the engine start/ stop feature, shutting down the engine when coming to a full stop. I am in Canada, and not sure if the US cGolfs will have this feature. I am not a fan of this feature, and would like to turn this off permanently. Is this possible?

Many cars have this feature, and start/ stop can be de-activated by pressing a button on the dash or console. However, when the ignition is turned off, it goes back to original factory setting. You have to press the de-activation button every time you start the car. a real PITA!

Someone told me on the Audi’s and BMW’s, if you press and hold the de-activation button for a long time, this permanently disables the auto start/ stop function?

I have been reading lots of posts from overseas Golf R owners, and the long hold-down method does not work there. Anybody in North America try this on their new 2018 Golf’s? Hopefully we can turn this annoying feature OFF!

It has been around for awhile, but don’t like the small delay when getting on the throttle, especially when making a left hand turn. when you have to jump quickly off the line.

The biggest issue I have is the wear and tear on certain engine components. Don’t like driving the engine hard, coming to a stop, and shutting engine down, while turbo is spinning max RPM and «hot» to boot! No cool down for turbo. I’d rather keep my engine running. I know the starter motor is extra heavy duty, but the duty cycles with start/ stop systems, it goes up exponentially.

Granted, if I’m stuck in bumper to bumper traffic, and not moving. I will shut the engine down after proper turbo cool down, and avoid unnecessary idling.

The Start/Stop feature is — in my opinion — the single most annoying fuel-saving gimmick in existence, and it certainly has no place in a sports car.

In the US, manufacturers are not allowed to offer a way to permanently disable it, as it would require federal re-certification by the EPA. Just another example of the folks in Washington telling you what you can and can’t do to a vehicle you own.

I would bet VCDS/OBD11 have a one-step fix.

probably similar, just search the module and adaptations if you really want to disable it

Thanks drunknfoo for the link. I have read that start to end. I think the mini timer module wired to the «Activation» button is the best mod for me. It will be one of the first mods I do, once I get the car. It’s just, I was hoping for an easier way.

I agree with a lot of you guys. we should be able to be turned off this feature if we do not want it.

Does anyone know if this engine has an auxiliary electric oil pump & water pump to keep fluids circulating when the engine comes to a stop? At least that would help the turbo cool down, & lubricate it, when engine stopped. I know some cars do, but I cannot find any info on this 2.0 L engine.

You mean no issues other than it being an annoying royal PITA? I rent cars in Europe two or three times a year that mostly have stop/start, and find that it’s something that ends up requiring active management by the driver. With a manual car keeping the clutch depressed overrides the auto-stop, which can be useful both for readiness and to keep the A/C functioning. Considering the heat/humidity climate extremes in the USA I would find stop/start totally unacceptable here.

At least up to now the NAR Golf R hasn’t been saddled with stop/start. I don’t know about other regions or Golf model variants.

Yes it does. I’m not sure of the functional details — anyone?

engine stop/ start

An idea who’s time has come and should go. think of the wear and tear on the engine and also the starter motor. how much are you going to save on gas? In the long run it is going to cost more. Just another thing to break. Typical German over engineering and no long term reliability. Now what happens when the thing refuses to start up after a stop? Oh it will happen. Stop falling for all the German nonsense. Then again i guess it must be that Cool Factor.

All the components related to the start/stop are beefed up and stronger, so that shouldn’t be an issue. Many brands have had this feature for a long time, so while most of us here won’t like it it’s pretty much standard on a ton of models now. Helps them meet their emissions requirements.

Personally i’d just disable it with VCDS and be done with it, no point ranting about it.

Yes, certain components are beefed up for the S/S system in vehicles to cope with extra stress it will receive. I work with an OEM manufacturer in regards to some engine testing & engineering. On a typical vehicle that has a life span of 10 years, the starter motor will typically start the engine approx. 5000 times. On a Start/ Stop engine, those duty cycles increase to between 50 000 and 500 000 times. That is a lot of extra wear & tear on many engine components. Typically the crankshaft bearing surfaces have to be increased 50-70% in size to cope with extra stress (the bearing closest to the starter motor). When an engine has been driven hard, and then immediately shutdown, causes lots of extra heat soak on engine components due to lack of coolant flow. This is why many manufacturers install electric cooling pumps to keep coolant flowing on engine shutdown. Also, some install extra oil cooling pumps or accumulators to extend turbo life as well. Extra wear & tear on turbo. Those are just some of the highlights.

Lots of extra undue stress for many engine components to gain a very small fraction in fuel economy. No thanks! I’ll keep my engine purring along and happy! To each his own. Short term, you will save some money on lower fuel costs, but in the long run, parts will fail. When they do fail, they are more costly to repair and or replace.

The Start/ Stop system is just a short term solution to keep government bodies happy. With the advent of 48 Volt electrical systems, manufacturers are looking at reducing engine RPM when coming to a stop. Instead of shutting an engine off, the engine will idle down to a much lower RPM, say 300-400 RPM. This has same fuel savings as shutting the engine down, but no added engine stress for shutdown and start-up. Added benefits include A/C operation remains, and quicker recovery times to normal engine RPM when driver hits gas pedal. 48 Volt systems are just around the corner. Audi using it on their flagship models, and all manufacturers have agreed to 48 Volt as the new norm.
