Should the S/S cut the engine while the vehicle is still moving (albeit very slowly)?

 

the S/S manuals ive had dont cut the engine till the vehicle is stopped.

It can cut the engine before the cars stops when off the accelerator.  It is not a fault and not all TSI or TDI with DSG,s behave exactly the same. 

My vRS didn't, but my GTI does.  Same engine, same DSG.  Feels a bit odd at first, but you soon get used to it.  The GTI is also quicker at starting back up one the traffic in front starts to move off.

I've never actually had it shut the engine down before a complete stop from memory. My DSG will only switch the engine off at 0 mph. 

Annoying that it kicks the engine back to life when I move to neutral and take my foot off the brake too.

 

But almost every single time I am in the car I disable this.  This is only enabled when I know I will be at lights for at least more than 30 seconds or say at roadworks.  

It's also disabled during the cold weather when I know the battery will be taking a hammering

 

So as Roottoot says your mileage may vary!

Mines an early model and doesn't do this. Later models do. There are some threads on the subject.

My 2L TSI manual does this also. If it's allowed to and not disabled!

My 2016 TDI DSG certainly stops the engine with the car still moving at times. In all modes to, be it S, D or ECO.

Interesting Paul. My 2015 didn't, but your 2016 does.  TSI vs TDI.  Mine was MIB1, isn't yours MIB2?  Have you got ACC? (my vRS didn't but the GTI does).  Just wondering now about the what's, why's and wherefore's.

@Gaz correct I have a MIB2, car has no ACC. 6speed Dq250. 

 

From reading about the DSG's (recent article in CAR Mechanic on rebuilding 7 speed dry version) "both clutches default to open position and apply no clamping force, thus ensuring that sudden loss of power does not engage both clutches at the same time which would damage engine and gearbox". One would suspect that driver/occupants would need a change of underwear if that happened too 😀

Not ACC related then, and I'm forgetting LD's Superb is going to have the DQ200.  Our 2015 Polo (192ps, DQ200) doesn't do it either.  Curious.

I rarely use stop/start unless on motorways with roadworks which is quite often these days. I find its is so more relaxing and am constantly amazes at how many miles can be covered using stop/start combined wit ACC without touching the brake or accelerator at all.
