I read something in another thread (can't find it now) that the Octavia will pull along at idle speed, without any need for a foot on either the clutch or the throttle and without stalling. I tried it in second and third gear this afternoon; foot off the throttle, foot off the clutch, the revs fall to idle speed and the car...keeps going. It even increased the load a bit going over a speed bump.

 

Now, I might be showing myself as ill informed, but I don't think my Mkii did this (I never tried it though). Do all modern engines do this, or is this a VAG 'feature'?I'm trying to think of a positive reason for why the engine won't stall itself? Any ideas?

It's due to the torque of the engine....I believe! It's great in the jams being able to crawl along in 1st without the constant need to dip the clutch in and out.....

If you went from London to Glasgow using the Idle speed who many MPG could you get, might take 3 weeks to get thier but if your not in a rush................ :think:

I would imagine a good proportion of any journey starting from London would involve lots of idle speed driving, at least  for the first portion of travel

not very many...

Most diesel cars will do that!

It has anti stall so that's what you will be feeling.

Good point too...forgot about that.

A friend of mine had a fiesta diesel van and you could get it up to about 35mph just by using the clutch and changing up through the box until you were in 5th.

My 1997 Octavia 1.8-20V do this also. And that is without DBW.

My Fabia VRS is capable of pulling me up a 15% incline on idle speed alone. Imagine the engine wouldn't like doing it for long though.

The dual mass flywheel sure won't.

Yoiu will find all modern cars will do this that have electronic injection.

It is just the idle speed controller (the same that keeps the engine running when the gearbox is in neutral).

Usually the idle speed is increased when in gear (from 800 to 1000rpm for example).

You can do this also in an petrol car too although the lack of torque at low engine speeds makes it less effective.

 

Using this principal you can manouvere a car very well at low speed without pressing the Accelerator pedal at all.

Pulling away from stand-still using only the clutch is also very easy with a diesel due to the torque from the idle-speed controller.

 

Its particularly useful in slow moving traffic, when assending (or decending) multi-story carparks or concentrating on other things while curb-crawling.

Does kerb crawling have the same meaning in Switzerland as it does in the UK? No criticism if that's your thing of course.....

I should imagine that it has and this was written tongue firmly in cheek ( what cheek or cheeks may well be questionable of course )

My mk1 1.9 110TDI used to happily do this, was a bit harder on the mk2 1.6TDI

My Octavia is a Petrol and it pulls quite nicely with the available torque. Also just discovered Mrs Isocrem's Hyundai does the same thing (though it's a lot lighter on power so doesn't quite do it as comfortably as the vRS), so clearly I'm backward on the technology front! I've got a dodgy left ankle that gets achy quite quickly in stop start traffic, so I'm hoping this newfound discovery can be of benefit to me.

Don't all cars do this? It's not specific to the Octavia. Petrol or diesel you can do it in almost cars I'd have thought.

I'm shocked that some see this as a new discovery?!

Yes, it seems they do. And yes, this is news to me. Sorry for the shock. Have a sit down and perhaps a nice drink, it's the weekend  :cocktail:

All fuel injected cars I've owned have done that. IIRC even my old SU carburreted BMC Minis, Maxi and Marina managed it on the flat.

Well it seems I've been living in ignorance for the past 20 Years of my driving career. All I can do is make up for lost time by utilising this driving option as often as I can from now on. 'I'm just off to the shops, love. See you next week"..

 Nothing to do with anti stall, more to do with the ECU trying to keep the idle speed up.

 

Its really not good for the engine though labouring it at such low engine speed.

Automatic is your friend :-)

It's not that achy 

I used to be able to do this with 2.0l carburettor petrol engines. As others it's a great thing in slow moving traffic, being able to bimble along "feet off".
