Hi,

I have three questions/topics I would like to discuss 

First, i am trying to understand if the coasting feature is could cause excessive wear or reliability issues for the dsg, searched the web for hours and i couldn't find an answer.

 

Second topic, can i clean the pcv valve my self, is it difficult thing to do, if there any guides online please share.

 

Third, since i purchased the 2021 ambition model, it came w.o reverse camera and w.o the key less entertaining 

To install a reverse camera, are there ali express cameras that comes pre-coded for the scala version i have? Or i might need to code it my self?

 

Is there way to unlock the key less entertaining feature?

 

 

 

 

Never seen or heard or issues with 'Coasting' mode with Wet or Dry Clutch DSG,s. Why would it cause excessive wear?

Is it with your Scala & a DQ200 DSG that worries you? 

Edited 27 July, 20241 yr by Ootohere

What worries me, is the multiple engage and disengage of the engine and the transmission, which could cause wear on mounts clutch's, fly wheel etc..

 

Its been happening with plenty engines for years now and DSG with a lot more BHP / Nm than the 250 Nm max that any DQ200,s are dealing with.

They never designed or engineered the system to be fragile. 

There is more to be concerned than the components you mention.  Like the MCU, and that is even where Coasting might never be enabled.

Appreciate your replies,

One thing i noticed, at least in Israel that engine and transmission mounts are been replaced after 60-90km on those 1.0 tsi dq200 combinations vs the manual which seems to last longer. I thought it is some how connected to that specific system of disengage the engine when lifting the foot out of the gas pedal..

It make sense no?

I suspect it might be environment / climate if they need replacing at under 56,000 miles.

This is something I've thought about, and I'm using ECO mode less now, as when in drive mode, lifting the throttle gives better fuel economy than coasting with the engine idling, though with a penalty of a loss of speed.

Cruise control works down to 20mph and seems to give optimal economy, if you pick a sensible speed, and don't lock the car to a speed just below a gear upchange.

 

Where do you choose driver modes?i found something in the safety tabs but, i didnt felt any difference 

I cannot say how this is done on the Scala.

On a UK model, if I select the ECO mode and take my foot off the accelerator, the car goes into a coasting mode.

 

This means that you don't have full control of the vehicle which isn't a good idea and frowned upon in advanced driving circles.

I assume that's a DSG-equipped vehicle?

@cwt Which engine has your Scala.

 

You have full control of the DSG when Coasting is functioning if you are awake, sober and doing the driving.

Touch the accelerator or brake pedal or drop a gear manually and drive is engaged, or just do not enable Coasting if you do not trust the engineers that designed the system and had vehicles type approved. .

 

It is a Manual put into neutral that was frowned upon in advanced circles, or an Automatic going to neutral and needing put back to drive.

Are we to assume that no Advanced Drivers, or Police Advanced Drivers or other Emergency vehicle drivers just 'Inhibit' Coasting?

1500 engine.

 

I'm still learning about the car, even though I've had it nearly 3 years.

 

Is it possible to disable coasting in Eco mode?

Found it it is on the gear lever 

Yes in sport mode there is no coasting 

I think there is away to cancel coasting in long coding, 

Keep your toe touching the accelerator and slightly pushing and the car will not be coasting.

There really is no issue as the car will not run out of control or pick up speed it just freewheels as you might when riding a Push Bike, and need to have power to get up a hill or as the speed drops and you are touching the accelerator it is in gear seemlessly. 

Just turn off that coasting crap with OBD11 ,nobody needs that, I turned it off and I am really happy about that.

Well I for one like it.  An earlier post suggested that fuel economy is worse when coasting, presumably as the engine is ticking over, whereas if left in drive the engine shuts off.

 

The trouble with the engine shutting off is that you get engine braking, so if left, the car will come to a halt much sooner.  So to hit the same stopping point as when coasting, you have to feed more fuel in.   I find this particularly when leaving a motorway.  So I don’t think it’s a valid argument.

 

Looking back years, my Dad had a manual two-stroke SAAB 92, which had freewheel/coast in top gear, (OK, it was a two stroke, so it was probably a good idea, even a safety feature!) as did my 1987 Vauxhall Carlton 2ltr Auto.  So it’s by no means a new feature.

 

Q. Is it OK to freewheel on a pushbike, or should you have fixed wheel, and keep pedalling, using pedal pressure to aid braking?

I will get my adapter in few days,do you under which module it is included for scala?

I forgot so I will check what I changed and will let you know.

I have only one very valid argument, coasting turning on and off made very noticeable clicking noise , and now it doesn't, thank you obd11.

So in 19 Gateway/ long coding/ FPA Funktion Freilauf default on- set to not active, and there is another FPA Funktion freilauf - also set to not active. Problem solved.

Yes, it doesn't take a genius to work out that if you coast the same distance as you would while being in a gear you are in a worse position economy wise.

 

To really benefit from coasting you need to have economy in mind when driving, appreciating and understanding lifting off the throttle as early as possible and rolling further than you would with engine breaking to counteract the fact then when you are coasting you are using fuel idling. This is not a lot of people, so IMO most people are using more fuel than they would without coasting. Granted, I don't think its a noticeable difference given the variables when driving. At the end of the day its just something to make the car appear more economical on paper.

 

As for causing wear, automatic gearboxes can't read your mind or the road conditions and especially when equipped with the smaller engines they change gear like crazy compared to if you are driving a manual so I don't think there is a need to worry.

 

 

There are plenty that can get more range out of a tank of fuel when using coasting rather than not.

But then there are engines from 90 ps- 280 ps or more petrol or diesel then different DSG,s, from different generations. 

So an generalisation is just that.   No point saying what others can not get just because you can not get the same. 

Location location location.  As to terrain what goes up comes down. Many can benefit from coasting dependent on where and how they use the vehicles.

 

As to 'Engines off',  that is not happening with the cars discussed here with a Skoda other than rolling to a halt.

Then with ACT / COD there is 2 cylinder shutting down.  2 out of 4.

 

Bentley or Audi and overs can have 4 out of eight or 6 out of 12 shutting down, and coasting and using gears according to the terrain / road and GPS.

 

As to a 1.0 TSI & a DSG, easy to just see how you do and if you do not like it then do not use it, 

as to selecting ECO, well that could well be an issue were there is no fuel saving.

Doesn’t on my 18reg Octavia 1.4 TSI

 

(I appreciate stop/start can be a pain, I often cancel that)

Thanks for only quoting part of my post.  Read the next sentence:  you won’t go the same distance on the overrun (ie in gear) as you will coasting, because of engine braking.   So to go the same distance, ie lifting off say at the one bar distance sign, and coming to a stop as you leave a motorway, you’ll need to feed fuel in - at greater revs than tick over.  

 

However, I’ve made my point, accept it or not, and I refer you to my sig below
