With regard to economy, just unplug the sensor for a month and check consumption, regarding brake wear,  I drive my auto partly in manual mode when slowing or going downhill, I always let the gearbox slow car, I never brake brown a hill untill he very late minute.

the only issue with the Merc is brake hold is lost

Firstly - sorry to ressurect such an old thread but it fits my circumaances well  :-)

 

Hi,  I am thinking of doing this on my Karoq (1.5 Petrol DSG) as I nearly had a flat battery today after not driving the car for over a week (its cold outside too). My usual routine is to take the car out every 3-4 days and give it a good 15 minute run to top up the battery as much as possible in the given time.  It annoys me that the smart alternator is working against me in this way and also annoys me that I most likely will only have an (at best) 80% charge on my battery just before laying the car to rest for a week. In the olden days I would make sure that I gave the car a good run without lights on and without other draining items on so at least I knew the battery was as charged up as possible.  Also don't like stop/start (personal choice) and turn it off every time I start the car. 

 

The thing I do use a lot is the AutoHold function when I come to a stop in a queue (or when I start off my journey as my drive is on a slope). The autohold keeps the brakes on until the revs are appropriate for the car not to roll back etc.  I was wondering if anyone with  a skoda and Stop/Start (and smart Alternator) and DSG has tried this little hack yet and whether the AutoHold still functions?

 

I know I can get a CTEK MXS 5.0 (or similar) but that is a faff - the removal of the plug is much more appealing if there are no other bad consequences.  My battery will also have a longer life as will my starter motor and my alternator (most likely). I can still stop the engine in a traffic queue manually if I want (and I sometimes do). I could also get a jump starter gadget but.... 

 

Thanks

Paul

@smipxare you confusing 'Hill hold assist' with 'Autohold'?  Autohold will hold the car on slopes as long as is needed once activated by pressing the foot brake hard enough, and with the engine running or stopped with stop / start, that is as long as 'autohold' is enabled.

No need for a foot on the brake, Touch the accelerator, or the brake to release 'autohold'.

'Hill hold assist' holds the car while your foot goes between the brake and the accelerator.

Both really. 

 

I rely on the car holding when I stop, take my foot off the brake and am still in gear (DSG) - Autohold

and

I rely on the car not rolling forward when I'm on a slope, pop it in reverse and slowly squeeze the accelerator (to reverse up my drive - uphill) + rely on it not starting to try and move off until the revs are high enough to prevent the engine stalling (as I'm on the slope) - standard for the DSG gearbox as I understand and active whether or not Autohold is turned on).

Exactly right.

So what has this to do with 'disabling' the Stop/ Start?

You do not have a Mercedes. 

Maybe you are confusing yourself ? or out for mischief on a boring cold evening?

 

This is a Karoq forum and the thread is concerning Karoq's - The chap was saying he did it on his Merc and I was asking the question whether his "downside" affected all marques with this type of technology or whether it was specific to the Mercedes.

Disabling the Stop / Start will have no affect on the brake system of Skoda models that have 'Auto Hold', HHC or e-Brakes.

 

While some say you can no longer disable stop / start with the latest cars, you can and dealerships have been known to when there are Battery or Stop/ Start issues.  (While they consult the factory some at a dealership lie..)
