donedavna ano... este som pletenec roztrhnuty... odrezal sa a navaril sa tam novy... odvtedy mi 2x vyhodili chybu motora (tankoval som aj na pumpe kde nazvyknem, starsia slovnaft pumpa).
chyby sme moc nestudovali, ale bolo tam nieco s dpf, s vyfukovymi plnynmi a neviem co este... vymazali sa a teraz pred par dnami mi to spravilo zas, ale chyby som este nedal vycitat :/ kazdopadne chybu vstrekov tam zobrazuje stale

Da sa to.....pisal som pozrem sa na to po viku a dam vediet..

Zero-quantity adaptation

Zero-quantity adaptation is the adaptation process which is used after the running-in phase (approx. 1500 km) for every single injector to assure the presence of a defined level of pre-injection.

To achieve compliance with exhaust emission standard EURO 4, precise metering of the very small fuel injection rate is required for pre-injection purposes.

Due to the deviation for the fuel injection rate over the operating time, the zero-quantity adaptation is performed continuously by the DDE control unit.

For every cylinder in coasting (overrun) mode, a small quantity of fuel is injected. This quantity is then varied until the desired torque rating is detected by the DDE. To calculate the torque rating, the irregular rotation of the crankshaft is incorporated in the equation. This irregular rotation is recorded on the crankshaft sensor.

This enables the DDE to detect the activation duration after which the cylinder starts to operate. The quantity of fuel injected during the zero-quantity adaptation period is used by the DDE as a correction value for the gearshift map of the pre-injection process.

The zero-quantity adaptation process switches from one cylinder to another in each overrun phase at:

engine speed 1500 to 2500 rpm (engine at operating temperature)

The zero-quantity adaptation has no impact on fuel consumption because only a small quantity of fuel is injected into each cylinder (approx. 1 mm3

Diky za specifikaciu, ale moja anglictina nie je az taka dobra. co to pls znamena?

Nepoznáš Google translate?

Uz som to tam hodil ale z toho prekladu mi aj tak nie je uplne jasne co teda robit

Zero-quantity adaptation je adaptacia ako kazda ina, v DISe sa to da resetnut, cez vikend som to skusal na mojom, ale moj DIS zacal strajkovat a vyhodil chybu 100.723 ... bla bla bla ... choj na diagnostiku a nechaj si to resetnut.

Resetnut v akom zmysle? To je ine ako premazat chyby?

adaptacia je nieco ako samonastavenie, konkretne v tvojom aute ich je viac, adapatacia vstrekov, vahy vzduchu, snimaca tlaku v raily a par dalsich, napr pri vymene vahy vzduchu sa hodnoty povodnej vahy zmazu a jednotka sa tym adaptuje na novu vahu. Po tej oprave co si mal to bolo asi treba spravit, je to len typ .. osobne som taky problem este nemal.

takze mam diagnostiku v servis motiv na trnavskej v bratislave.
Diagnostikovali mi to, vypisalo im to opat chybu 3 vstrekov (aj EGR ale to predtym nevypisovalo)
Adaptacia je zevraj ok (poradie v strekov v motore bolo rovnako zapisane ako na diagnostike).
Lamali si hlavu s tym, ze nevedia co to moze sposobavat. Vynuloval mi stredove korekcie, ale povedal ze nevie ci ot daco spravi.

Neviete mi poradit co dalej? uz som fakt zufaly

pod stredovymi korekciami myslel Zero-quantity adaptation? Ci nevies? tiez som z toho jelen.

to neviem, len tak ako mi bolo povedane :/

Chlapi nevie nikto co dalej?

pre zhrnutie:

Na diag ukazuje chybu troch vstrekov, vstreky boli na stolici a su ok
Najnovsie ukazuje uz aj chybu EGR (chybu vtrekov zobrazovalo aj pred tym)
Vstreky su ulozene spravne, diag ukazuje rovnake poradie strekov ako realne su dane v motore


Nikto kto by s tym mal realne skusenosti ???

zajdi k simikovi do TT, z BA to nemas daleko
ak to nevyriesi on tak asi nikto na slovensku

mal som podobny problem x5 e70 3.0d. chlapik kupil auto v pamati vtedy neboli ziadne chyby korekcie 0,1-0,5 cize vstreky na 100 percent. jazdil na tom mesiac a zacal sa stazovat ze mu zhasina motor za jazdy. pocitac ukazal vstreky uz neviem kolko ale myslim 3,4,5,6. zacal do toho davat aditivum prolong a pomohlo to na cas az jedneho dna rano nastartoval auto na vsetkych 6 a potom zdochol a takto to islo dokola na koniec to bol vstrek na 6 valci.
