So apparently there are memory modules for the auto start/stop system, which remember the last setting when you turn your car off. My dealer said they confirmed compatibility with Tucson and Santa Fe so far, so maybe it will work for the N (i30 in general?) also...
Anyone looked into that? be it with the dealer or somewhere else?

If I remember correctly, when I did my test drive, the start/stop system was again active after a short stop.

Yeah, that's because it's on by default every time you start the engine and I have always seen it set like that in different cars, which is very annoying. But I spoke with my dealer recently and he said they now sell and install memory modules that remember the last setting permanently...

That would be really neat. My current car 2011 VW Tiguan has that feature and it is super annoying turning it off every morning. I have owned that car for 7 years and still don't like the default setting. I wish it would work the other way around.

Unfortunately it has to be like that by law. At least in Germany. The car has to start up in the setting, u might be able to reach the declared values for mpg...

Any idea of cost? I'm also wondering what it is, an sd card that fits in somewhere? Seems like the sort of thing a punter can do.
 
So I just got the dealer to install the module for the ISG system in a Santa Fe i have in my family...
They stapled a dealership warranty in the service book, so looks legit. Apparently they have a partner company that fits various accesories for hyundais, like also closing windows with your key remotely, parking sensors for the models without it and etc.

However now the ISG is permamently off now, even tho the button works and displays the toggle on the dial display

They charged about €50 plus installation.

Truth is, the ISG ina manual car is not that bad, but in an automatic it's total bullshit imho, because the delay is much more annoying.

I was also wandering about the ISG vs turbo.
I always complied to the rule that you should use the last moments of your journey to go easy and cool the turbo down before shutting off the engine. Is this approach outdated?

I wonder, if you push the N and come to a halt will the ISG work, at least when the turbo is really hot? Someone did mention the fan is running for a while after turning the car off, I have some doubts tho...
 
I think that turbo cool down still applies. I turn off the stop/start system when I'm doing track days or anything more than normal driving, and then allow the car to run a few minutes after stopping. On my last Subaru I installed a turbo timer, not sure how that would work with the i30N?

I've been wondering about that too. Back in my Subaru owning days, we used to let the car run for a minute or two before turning off so that the oil continued to circulate through the turbo whilst it cooled down, otherwise it had a habit of turning to sludge in the (potentially white hot) turbo.

I've always done this with Turbo charged cars but only if I've been pushing the car prior to coming to a stop and turning the car off. So, just sit and let the car idle for a couple of minutes. It's a habit I'm now in with the I30N too.
 
I've wondered, but the manual is silent on the matter. Bearing (pardon the pun) in mind the 5 year warranty, I can't see it being an issue or it would get a mention.

It was about oil sitting in the turbo getting fried by the heat, but I thought modern designs had overcome that limitation, but can't remember how.

Honest John says.

Yes, I think it's probably been a useful thing to do with older turbo charged cars, but isn't really applicable to modern one's. It's a habit of mine now though, that's hard to break!
 
The problem isn’t so much the oil turning to sludge...

The problem is a turbo can spin at speeds well in excess of 100,000 RPM. If you turn the engine off, you also turn off the oil supply to the turbo while the turbo can potentially still be spinning.

Bearings spinning unlubricated can cause serious damage. Also if the turbo has water cooling the water that is in the turbo can get superheated and cause issues within the cooling system!

Have you seen the turbo has a separate cooling pump? My dealer and few others told me that this will prevent some damage. The pump is still cooling till turbo reaches uncritical temperature. Sure, what you shouldn't do is turning the car off with high rpm or high oil Temps. But I think it's a nice feature.
 
It seems that for a manufacturer who builds down to a price, for which I would have thought standardisation was a key element; Hyundai certainly likes to muck about with the 'standard' specification between markets.

But if you omit that technology and equipment you can reduce costs... maybe goes some way to offsetting costs for the glass roof or whatever!

Also they have altered the suspension for the Aus market from what I can make out too!
