What does a yellow circle warning light like abs but the abs is replaced with what look likes goggles - the steering wheel auto stick has this icon in white - the yellow currently flashing on dash

A piccie would be helpful. And what vehicle?
Any way of asking the truck what is wrong via the dashboard?
Failing all that and guessing is a symbol of clouds of smoke coming out the exhaust? Re-Gen?
exhaust brake?

I want to know what that is! [emoji15]
Exhaust brake engaged, as above.
Didn’t get chance to take image as agency driver - operating the stick lever turned it off so relief - couldn’t find the Merc tractor unit symbol online hence asking on here
So…turning off the exhaust brake…also turned off the exhaust brake warning light?
All`s well that ends well.

Yes as above exhaust brake but I call it retarder don’t know if there different technically

Exhaust brake,
Engine brake,
Retarder (DAF call it an intarder)
Are all different. They may all be controlled by a stalk, but they do operate different bits of nutsnbolts and have do different degrees of effectiveness.
From a couple of years ago.
"See if we agree on terms first?
Exhaust Brake
flap covers exhaust to improve engine braking.
Engine Brake (Jake Brake)
Alters valves yo turn engine into an air compressor, increases engine braking more than an Exhausted.
Retarder (Intarder on DAF)
Fluid pump on back of gearbox that converts energy from prop shaft (hence the rear wheels) into heat.
Let’s ignore Electric Retarder such as Telma as UK truck rarities?
The first two, using modified engine braking, work best at higher revs, in lower gears. The retarder work a best at high road speed and isn’t dependent upon gear or engine speed.
As brilliant as Retarder are, they are expensive and heavy. (I think France allows 500kg gross extra, if fitted, so no penalty for safety) In the mostly flat UK they aren’t common, but although not universal, are found around Alpine countries and Iberia.
If you’re not fitting a retarder, then an engine brake is better than an exhaust brake. If fitting a retarder, than an engine brake isn’t so necessary, and an exhaust brake will suffice.
Discs should dissipate heat better than drums.
I don’t know off hand if current lining/pad material is much less temp sensitive than previous asbestos based types?
We can’t use F1 type materials as, although they work well at high temp, they don’t work well when cold."

Yes, for the most part I agree. However, and I know it’s pure pedantry, an “Exhauster” is really a pump used to create vacuum. An exhaust brake,as you correctly point out, when.activated, blocks the exhaust pipe, and causes a build up.of pressure which helps to slow the vehicle. My Scania has a gearbox retarder which can be combined with the exhaust brake, and thus gives very good levels of braking, even on the severe gradients found in our part of north west Scotland, even to the extent that loaded, on a wet road, and in a medium range gear, the retardation effort is sufficient to lock the drive axle momentarily, until the ABS takes over.
Franglais You mean exhaust brake. An exhauster is actually another name for the vacuum pump which is used to supply power assisted braking for diesel powered vans and was used for an earlier generation of heavy vehicles. It was unable to provide the level of assistance provided by compressed air systems, although some would argue regarding certain a manufacturer’s air system’s abilities in relation to another’s vacuum system.
@ Old John and @ cav551
Guilty as charged.
When I gave my quick description of “Exhauster” I should have said “Exhaust Brake”.
Fully accepting that I will go back and edit that post, so anyone picking up at that point, and not following through doesn`t get confused. I do agree that slack use of terms can cause problems.
Ah. A new Mercedes with the twin screen dashboard.
Exhaust brake light. Lift lever up to turn it off.
Ken.
I would also recommend a tin of spray polish to clean the dashboard.
