no codes i assume? no cel, not in soft limp mode?

I wonder if the vacuum check valve issue affects the M256 engine. https://mbworld.org/forums/w212-amg/...ve-repair.html

[QUOTE=W205C43PFL;9112175] predpokladám, že žiadne kódy? žiadna cela, nie v režime jemného krívania?

Zaujímalo by ma, či problém s podtlakovým spätným ventilom ovplyvňuje motor M256. https://mbworld.org/forums/w212-amg/...ve-repair.html [/QUOTE

The car had a downpipe without a cat. With it the car had 320 kW when measured. I put the car in production condition and it only has 280 kW.

So you are saying there is no check engine light, you put a OBD scanner in that is capable in reading MB codes and there are no stored fault codes. You dynoed the vehicle and it is not making enough power? Did you put vehicle on an AWD dyno and in dyno mode?

[QUOTE=W205C43PFL;9112191]Takže hovoríte, že nesvieti kontrolka motora, vložili ste skener OBD, ktorý je schopný čítať kódy MB a nie sú uložené žiadne chybové kódy. Vylepšili ste vozidlo a nemá dostatok energie? Nasadili ste vozidlo na AWD dyno a v dyno režime?[/QUOTE

It's in Assyst Plus mode if you hold down.

[QUOTE=exturnul;9112216][QUOTE=peter1996;9112210]
Ak podržíte tlačidlo, je v režime Assyst Plus.

Ohlásim sa neskôr, tiež ma to zaujíma, pretože môj CLS53 robí iba 4,6-4,7 0-60 a je to dosť zvláštne[/QUOTE
]I tried the race my e53 vs c43 2018 several times. The average was one car length faster, I was up to 200km/h.
I have 280kw and it has the same power but a lighter car and a loss? There is also not much difference in torque, even though the e53 has an additional electric motor that produces 12kw and 250nm at a certain time.

is this mode for use on a dyno only to get accurate results from the 4matic system? or what's the point of it?
