    This may sound like a silly question but......

    It is my understanding that if you give the engine some beans, you will need to let the turbo cool down or whatever before switching the engine off.

    How does that work with stop/start? I havent experienced the stop start not working whatever load I have put on the engine. Does this mean there is no need to let the turbo cool down some before switching the engine off?

    Stop/start is a tool that may or may not be useful for saving fuel in urban motoring.

    "Giving the engine some beans" is the type of driving you are unlikely to do in town.

    Unless you drive like an absolute moron in urban traffic turbo heat is unlikely to become an issue.

    Agreed..however when you stop at a junction or lights the start stop will still work when your not urban driving ie motorway. Is this likely to cause an issue to the turbo long term?

    Not many traffic lights or junctions on motorways round these parts.

    Motorway cruising will not get the turbo hot enough.

    If in doubt simply keep your foot on the clutch or disable stop/start using the button.

    Today we are not using specialist turbo installs from the 80's. The 1.2/1.4 TSI engine is mostly driven by people who have no idea what a turbo is or does and they probably don't realise it has one. It has to be engineered to be idiot proof and expecting the average idiot to do what the manual says or even read a manual is going a bit far. There is no mention anywhere in the manual about allowing the turbo to cool off so why worry.

    Sorry I meant when you leave the motorway, there is always a junction/roundabout or similar.

    Clearly not on the motorway.

    I know this is old, but you can use a timer to come on for a second or so when you turn the ignition on to activate the start / stop disable button.

    To protect the battery, the Start/Stop function will not operate if the battery voltage or ambient temperature are below preset parameters. You can alter these parameters using vcds or OBDeleven, but as everyone has said, get used to it or use the OFF button.

    I've turned mine off using obdeleven as above. The sheer number of roundabouts which I have to queue at and for which the delay in stop/start means the difference between making the gap in traffic to cross the roundabout or not meant that it had to go.

    Is this another area where DSG loses out to manual? :joystick:

    Whilst I agree with the analysis of the DSG implementation, I find this is actually a driving challenge. The amount of brake pressure necessary to slow to a halt but also avoid stop-start requires a deft modulation, which is a challenge I accept. I find it means I drive more smoothly as I think ahead more so I don't have to brake with any great force, or at least I can ease off the brakes as the speed gets near zero. There are also other aspects, like if the stop-start has deployed (I sometimes let it, if I am at traffic lights that will be red for a while for example), and the auto handbrake has engaged, you can give the throttle a light tap which will restart the engine but not release the brakes. When it is time to pull away a progressive application of the throttle will release the brakes and make a nice smooth getaway. I find this smoother than simply waiting for the green light and mashing the throttle, having the engine start, the gear engage and the clutch let out in one jerky movement.

    sounds complicated :D

    the other thing I do not like is if u just lightly press the brake( so stop-start won't kick in), the clutch seems to be engaged for a couple of second )

    I'd rather loose couple of MPGs than burn out the clutch, so I keep stop-start off, it was OK too fool the emission test bureaucrats but not me :cartman:

    My view:
    In normal traffic conditions it's ok.? So stops at lights etc no problem.
    In congested rush-hour traffic it's useless, it can cut-in 20-30 times in the space of half a mile queuing on an incline to a roundabout on my daily commute. This in my mind is doing more harm than good.
    So, it's just become part of my startup routine - unlock, get in, plug phone into USB, start, seatbelt, turn stop start off, now proceed to work.
