Start / Stop

[Skydance]

Good news and bad news then Skydance, bad that it was missing in the first place but clearly good that it’s a problem that should disappear when the module is fitted.

It maybe that the module detects whether a trailer is being towed or not, a missing module and the cars thinks that there is a trailer and won’t enable S/S.

Absolutely. It is good news. On the aftermarket some one will remove the module to disable auto stop/start in future for many of those who want it. However, software may be required in addition.

It’s just too sensitive try doing a 3 point turn boardering on dangerous catches you out.

 

[Shaky]

I don’t actually turn mine off, I leave it on and let it turn off at traffic lights or in heavy traffic etc.

If I am at a junction and looking to pull out, if it comes on, I just let the pressure off the brake pedal and the engine kicks up, that way I am not trying to pull away with a stopped engine. It’s that very scenario I think it could get someone in trouble.

You could just drive a LR Discovery 5, that thing nearly got me killed a number of times, put my foot down for a quick getaway, a cup of tea and a sandwich later the car decided to move off !!! Not annoying at all.

BMW must be worried about the extra engine wear as the have put in more durable l bearings in

can't stand the bloody stop/start. trying to get into auto mode to select it off on first start but keep forgetting

I agree with this. It has a horrible turning radius so most parking jobs require 3 point turns. Killing itself before I can put it in reverse is just lame. Like chill, I am just trying to park here. LOL

 

[Tom109]

I cannot see any reason why anyone would leave start/stop active. It’s a horrible idea.

Yes and if you calculated the fuel consumption at idle you see that it won't save the planet.
The famous and highly respected Fraunhofer Institute published a study in 2004 which already has shown that keeping the traffic flowing is the best to reduce emissions. But that is the most expensive and unpopular solution from the perspective of the officials and the government.

Ok, the engines can cope with stop/start systems better than a few years ago. You must just look at the starter, which can take far more starts then in earlier days, but the dependencies, complexity and the number of sensors which may fail or bad software...(ok...that is absolutely unlikely) increases again which can cause related damage thereby.

First car I have with start-stop, and it works very well.
I don't mind at traffic lights and "very" heavy traffic, when sometimes you get stuck for 10ns of seconds.

But, as a lonely exception, I do respect the STOP signs (even police doesn't!) even when I can see and don't see any car coming, and then I hate it: stop, motor goes off, start immediately. When I am aware of it, I switch it off.

And as a side comment, about 10 years ago, with my former car (no start-stop yet) I arrived at a place with high visibility at a stop sign, my youngest son with me in the car:

• Me (to my son): nobody respects this STOP
• (I stopped)
• [bong]
• Me to my son: get out and memorize the number plate (you never know)
• (I got out of the car)
• Other driver, angry: Why did you stop?
• Me: there is a stop sign!

Finally, everything went well, he was insured, And my car got repaired for free.

Mine has never worked and IA doesn't seem to know why. Saves me having to constantly turn off but i would prefer it works as it should. We only have 1 other car with stop start which I always turn off

Yes that would annoy me too, ironically. Should work as designed and then your input/choice to disable it - permanently is what I would appreciate.

Don't sweat the small stuff and all that but sometimes these things niggle.

My dealer told me that the reason why stop/start doesn’t work is because it’s missing a trailer module from the factory.

thanks, I will mention that to mine

@Tazzieman, exactly!
Btw. do you always adapt your flag to the country you are in?

For cold engine yes, for warm engine not so much.
Dumb still.

Ha! I just noticed that! It appears the forum software is spying on my login location.

We'll assume that in a few days I will become Irish...

Agreed.

Also repeated start stop not good for the turbo charger. I always idle my turbocharged cars for 1-2 minutes prior to shutting them off. This allows the turbo to spool down with positive oil pressure along with minimizing heat soak as the oil allows it to dissipate heat effectively after high demand such as freeway driving or acceleration from a stop.

If you get a green light and get into boost to accelerate up to the next intersection where the light turns red and you come to a stop the auto stop will kill the engine (and positive oil pressure to the turbo) while its still spooling down spinning at 10K’s+ rpm. Not good!

Immediately after I lower the handbrake, I depress the S/S button.

It looks like this relay - https://www.amazon.com/dp/B0744HSF8P/?tag=globalgrena0b-20 - with a ~1-5 uF capacitor in parallel with ~1-10MOhm resistor should do the trick.
