my new unit is limited to 68mph with no overspeed so I’m not fussed now lol 
stagedriver:
Mwahahaha all you loosers. My coach doesn’t overspeed till I hit 70 when im sailing by - suckas!
In the outside lane with 52 passengers onboard! 
watch out for that central reservation though pal! 
keep smoking your crack pipe, r kid!!! 
Your tacho doesn’t know if you are doing 50 in a 40 zone , 40 in a 30 zone, but thnks you are doing “overspeed” by maybe doing 52 or 58 depending upon your speed limiter being set to 50 or 56…
Most seem to kick off over 60, but you’re not going to be doing that speed except down reigate hill on the M25 or something.
I asked a VOSA official what they thought last November, and got told that “momentary blips through 60mph are something we’re not worried about. A speed spike lasting over a minute or two is another matter IF it’s over 60”. In a 50mph limiter (or cruise set to 50) then the exhaust brake keeps you under 60 even downhill, assuming you’re not carrying a full weighty load.
Avoid pulling out to overtake other artics, and then being left high and dry in the middle lane!

If i remember right its about 5 kmph over your limter speed but doubt it be to long before VOSA etc follow in footsteps of their partners over the water and start dishing out fines for it because they will say you dont have the vehicle under control as its ‘running away from you’
I think I better get ‘Eco-roll’ disabled on my FH then.
Somewhere in the ether there is a Vosa guide that basically says that 10 minute overspeeds in the UK will be lokked into as there are only 3 hills in the UK where you can overspeed for 10 minutes (don’t ask me where). The law in the UK is 60 mph on motorways, equates to ~96kph. Company policy is a different matter though, my co are very strict, so I set the cc to 87 and the braking program to +3kph overspeed, works for me.
i just wait for the little orange light to come on, then push the ok button to extinguish it…never been called into the office since, but you have to keep an eye on it, for its likely to come on at a later time even if your not exceeding the limit.

Yup. If you don’t catch the first overspeed coming up on your tachohead, half way down the hill, it’ll keep coming back to haunt you every minute or two till you acknowledge it.
…and am I correct in saying that if you don’t cancel said event on the tachohead, then any subsequent overspeeds are not recorded■■? I’ve always wondered about this and am very dubious about it, but have never put it to the test as, well, I just bumble around at my own pace… Just wondered though!!

No, you are incorrect.
Pressing OK, or whatever it is on your tacho merely means you acknowledge your overspeed, it doesn’t cancel anything.
Your tacho will still record every overspeed, but instead of acknowledging each one individually, you acknowledge them all at once as you click ok when you park up. You have to click ok to clear the tacho screen before you click over to rest.

You need the overspeed function to be set to 5kph+ to allow the I-roll to work, you will get an E symbol on the computer, you also need the engine brake stalk to be 1 click down as well.
I think the tacho can only record 30 overspeeds as mine always says 30, not sure if thats correct? 
My wagon regularly tops 90mph going down the hills on m74 at night, I dunno if anyone can top that?

Errrm, no you don’t. Not on an 18 month old Actros you don’t anyway.
The overspeed function can be set by an appropriately qualified and equipped grease monkey (with clean hands 
) to anywhere within a prescribed range, from 0 - 6 kmh, I think I remember reading.
Eco-roll can be set by you (the driver) to anywhere between 2 - 6 kmh (unless it’s been changed on the newest Mercs). If you reduce your cruise control speed, your eco-roll setting will increase up to 6 as you do it. It’ll also reduce back down to what your previous setting was as you increase your cruise control speed back up. In the gear display area of your dashboard you’ll have A and E when Eco-roll is on, which it is normally. If you switch it off (A only), switch to Power mode (A only) or go to manual (M only), eco-roll will turn off.
(By the way, has anyone noticed any difference at all between POWER and normal settings? I’m not asking what the book says happens, I’m asking about what really happens, on the road, approaching a hill, fully freighted. Has anyone noticed any difference?)
If you have engine braking on at all, you don’t get eco-roll at all.
Eco-roll switches in if there is no input from the ecu or driver for over a set amount of time (I can’t remember for sure, but 5 secs I think). So rolling down a gentle incline, no increase in speed to automatically bring your engine brake in, but no decrease to need any fuel to be fed in to keep your speed up. It works in cruise control or loud pedal control, but if you have your engine brake on at all, as soon as you lift your foot off the engine brake kicks in, so no eco-roll.
the stoneridge tachos in stobarts scanias show an “overspeed pre warning”…if you get the speed back down under your max limited speed within about 30 seconds you dont record an overspeed.
Simon,all that happens in an Actros in power mode is that it makes more noise as revs hold up but no quicker.have not used that button for 3 years now.

I tried it, to see what happened, when I first got this wagon. I couldn’t see, feel or hear any difference what-so-ever. I’ve ignored it ever since
I get the same thing in my Actros now xamtex. But in the UK, I ignore that too.
As 60 mph is the limit in the UK, 96 kmh is not an offence or an infringement.
My boss isn’t an idiot, so I don’t get any grief off him.
VOSA or the Police are quite welcome to frown at me all they like. I’ve broken no law so they can’t do me for it.

well an actros is not a fh
hi all lets get 2 facts right someone said speed limiter law ; it is not a law it is regulation second and most important you have to be seen to speeding in the uk ie cameras and eyes that is uk law
regards gazzap
too bloody fast
Your not going to keep your licence long doing 90-mph in a truck… A74 is a hot spot for plod .
