I am still after 2 years of motoring not really into the start/stop system. Ok I follow the philosophy behind it, and remember my trips to Switzerland over 30 years ago when we turned off our engines whist stopped at traffic lights....But does the stop start system now being fitted reduce the life, and make the Seat parts bin very happy, of components such as the starter motor, battery, clutch?? Any of you mechanics guys out there able to advise?
Stop start. Does it take its toll on components?
- Thread starter Pgcreature
- Start date
Obviously it's there for emissions reduction, but your right it's certainly highly likely to be a win win for the seat parts department, not really am issue for us owners of new or nearly new cars but will probably start to be an issue for others as the cars get older, as it clearly will shorter the life of the starter motor, plus the stop/start system adds another layer of complication if it goes wrong meaning more cost in fault finding etc
Can't see it having an adverse affect on the clutch life though and probably minimum or no effect on the battery life as that's what a starting battery is designed to do, deliver high current in short burst, unlike a lesure or deep cycle battery or similar
I am not a great fan of it. I tend to switch if off if I am in a traffic queue and I know I will only stop of 10 - 15 seconds.
mine is off as soon as i put the car in 1st gear- second natue and iv only had the car 6 weeks. its only logical that it would cause additional wear on some parts, no?
I've often wondered this and find myself switching it off as soon as i start the car. Perhaps the fuel saving is offset but the cost of replacement starter motors?????
Surely the starter motor is made to take all the extra work, as the service manager at my last dealership ran one for two years and then it was sold to a local taxi firm, and was still working fine after a year as a cab.
This. If you've been giving it a bit of a thrash, you shouldn't just turn a hot engine off which is what stop start does.
If you have been on a hot run surely you are out in the country or on a motorway, so plenty of time to do a cooling down slower run, before you need to stop. Or if you do hot runs in built up areas and must come to a quick stop, just lift off the brake and the engine will restart, a couple of seconds won't harm a hot engine, only if you turn it fully off.
Ummm no. You come off the motorway and usually straight to a set of lights. Engines stops - possibly for a minute or more. I'll keep mine running thanks.
Same if you have been on the motorway for a while and it all comes to a stop.
I have tried my same trips with and without the S/S working - I have not seen any difference in the fuel consumption so it now stays switched off.
I dont think its really to do with fuel economy, more likely emissions. Either way, as soon as I locate a friendly soul with Vagcom it'll be deactivated as I'm fed up of turning it off!
Although the current turbo's have also additional water cooling which runs for a minute or so after switching the engine off but I would never switch a hard pushed engine off at the first stop like I have to do at an exit at German Autobahn's where often after a sharp bend is followed by a traffic light.
That is why I switched the S/S off in VCDS.
Just want to take no risk and just want to keep the turbo at good health.

Of course the stop-start system will take it's toll on the car, how could it not?
Take the starter for example. A motor, solenoid and a gear on the end. A wear item with a finite life. If your stop-start system operates just once while you are driving you are doubling the work done by the starter on each journey so over the life of the car, you are halving the life of the starter!
But of course the stop-start typically works a lot more than once each trip. From what I understand they have beefed up the starters used in stop-start systems but I seriously doubt that they have quadrupled the quality of them. Who knows exactly how long they will last but my guess is longer than the warranty, nowhere near as long as the car. I reckon we'll see them start to give up around the 50k mark. Far enough down the line for most people to consider it reasonable and for the new car buyers not to give a s***. And that's just the starter.
These additions to cars are there for one reason only. To make the car look economical and efficient on paper. Saving the second or third owner of the car money does not sell new cars. But we keep cars for a long time so the stop-start button gets hit every trip.
