sej ne dela normalno, samo po privzetih vrednostih dela - ne odčituje.
Če bi imel stik, bi skoz ven metalo, kle ti šteka nekaj na turbini ali pa na regulaciji. Probaj kar sem napisal. To da zabije map je normalno, se dogaja ko ga zatolče za več kot par sekund ostane minuto do dve na absolutni vrednosti.
AEgir: ti ventili so najpogostejša okvara na VW motorjih. Tako bencinarjih kot dizlih, samo da ima regulirano turbino.

Zanimivo, navadno so te ventili dokaj buletproof. VW spet orje ledino.
Drgač pa če ti točno piše, da ti plus senzorja prebija, bi po moje znal bit, da točno to dela.
Kabli od zunaj lahko zgledajo noro dobro in super odlično. To pa ne pomeni popolnoma nič. Važna je vsebina in marsikakšen kabel dobro zgleda, not je pa masaker. Žice senzorja preveri od ecu-ja do senzorja pa če moraš cel loom razkopat, ga daj in ko boš 170% da ne dela točno to kar ti sporoča napaka, šele išči napako drugje.

Ma ja, VW ravno ni sinonim za inovacije, razen virtualne glede ekologije.
Očistit ali zamenjat boš moral ventil za tlak turbine, ali pa očistit nastavljivi del turbine. Podobno se dogaja, če natankaš bio dizl in ti zaštopfa ali ceno injektorje in visokotlačni del "nadomestek Bosch pumpe". Takrat ni čiščenja, je le menjava.

Na strani 270 do 280 nikjer ne zasledim da bi bil kje ta ventil.
Je cevka speljana iz konzerne na turbino.
Prav tako tudi fizično mi tam sploh ne gre kak konektor ali kaj drugega

res stavek leta
na 26-2 (stran 387) se vidi da imas VTG turbino in ne staro verzijo z wastegate. Definitivno si je crknila membrana ali pa imas zapacane krilca na staticni strani kompresorja
odpni cev in jo z inekcijo ali Vakuum pumpo zvakumiraj, da vidis ce se lopatice lepo premikajo in da membrana drzi. Ce je to v redu, odvijaci ona 2 vijaka ki drzita konzervo, in na roke premikaj stangico, da vidis ce kje zatika.
Ker je tole klasicen primer za napako positive Deviation - vsak mehankar ve kaj to pomeni.

Živijo!
Sem pregledal servisni priročnik.
Ta motor nima elektromagnetnega ventila za krmiljenje turbine.
Turbina krmili sama sebe z WASTE-GATE ventilom.
Kar pomeni da tlak ki ga turbina ustvari pri določenem tlaku odpre ventil v izpušnem sistemu da spusti odvečne pline mimo turbine. In tako uravnava tlak.
Napako moraš iskati v turbini kot ti tudi piše v servisnem priročniku na strani 01-16 (list31 v pdf)
"
Check G71
⇒ page 23-49
- Check turbocharger
⇒page 21-21; Checking

Checking turbocharger
"
Preveriti moraš tlačno membrano na turbini kot je napisal že Kr3mn1 (piksno),
če lepo premika ročico do ventila.
Lahko se zatika ročica.
Lahko je pa pri vžiganju z START sprejem prišlo do eksplozije plinov v sesalnem kolektorju in je počila membrana v tako imenovanem aktuatorju.
Preveri tako da z pumpo za kolo pumpaj do 1,5 bar (2,5bar absulutno).
ročica mora ventil lepo premikati
Glej sliko na strani 21-12 (list 281 v pdf)
Upam da je to to

kr3mn1 napisal/-a:tlacno je krmiljena ja, moja napaca.
je pa VTG tole Mato, WG je vzdolzen, tale je pa na srcu, da lahko vrti kaskado. Vsaj po sliki sodec
Hmm lahko da je dejansko VTG ampak v priročnku na strani 21-2 lepo piše
10 -Wastegate
♦ Part of turbocharger and cannot be renewed
Bova morala v ribiško vas, da pogledava na dejanskem pacientu

fanta z ODPRTIMI rokami vas pričakam.....
ne nima, toj zapresana konzerva, not je pa membrana in fedr. Drugo dobis lahko pri recimo turbine.si, okol 50 evrov, samo moras vedt kako mocna vzmet je oziroma tip.
mato: pust ti paradajzarje da pisejo kar hocjo, preberi si tekst 21-23
drgac mi pa ni dal miru, sm le nasel na koncu

pise da ima VTG lader.

Še nekaj sem se spomnil. motor je opremljen tudi s tem. Škatlico smo odprli da smo videli kaj je notri. Če sem prav razumel članek za nek volkswagen motor, bi lahko bil tudi moj vzrok. kaj menite?
Crankcase Ventilation System
25
System Overview
A primary oil separator is installed on the cylinder
block just below the engine coolant pump. A baffl
e
plate in the oil pan upper section prevents engine
oil from being drawn out of the sump at the gas
extraction point. In the primary oil separator, the
blow-by gases fl
ow through a labyrinth to separate
coarse particles from the oil. The primary oil
separator has two separation stages which work on
the baffl
e-plate principle.
The separated oil fl
ows back along oil return lines
into the oil pan. The blow-by gases continue to fl
ow
from the primary oil separator through a channel
in the cylinder block to the cylinder head. The large
cross-section channels results in a low crankcase
breather gas fl
ow rate which prevents oil droplets
from travelling along the sides.
A fi
ne oil separator is integrated with the cylinder
head cover. A single-stage cyclone separator with a
parallel bypass valve fi
lters out any residual ultra-fi
ne
oil particles.
The separated oil fl
ows into the cylinder head
through a port in the cylinder head cover; from there,
the oil is returned to the oil pan. To prevent intake
of the engine oil under excessively high vacuum, a
check valve is installed at the end of the oil return
duct. This check valve is installed in the honeycomb
insert in the oil pan.
The blow-by gases fl
ow along a duct integrated in
the cylinder head cover to a two-stage pressure
regulating valve. The pressure regulating valve
prevents excessively high vacuum from developing
within the cylinder block.
The pressure regulating valve is installed in a housing
together with two check valves. The check valves
regulate blow-by gas fl
ow depending on pressure
conditions in the intake manifold. If a vacuum is
present in the intake manifold
(for example, at low
engine speed)
when the exhaust gas turbocharger
is not producing boost pressure, the blow-by gases
are drawn directly into the intake manifold. If boost
pressure is present, the blow-by gas is inducted on
the intake side of the turbocharger.
Crankcase Ventilation System
26
Positive Crankcase Ventilation
This system supplies the crankcase with fresh air to
mix with blow-by gases. Fuel and water vapors in the
blow-by gases are absorbed by the fresh air and then
discharged through the crankcase ventilation system.
Fresh air is drawn in from the intake air system
downstream of the air fi
lter and Mass Air Flow
Sensor. A breather pipe is connected to the cylinder
head cover via a check valve
(PCV valve)
.
The PCV valve ensures a continuous air supply and
that unfi
ltered blow-by gases cannot be aspirated
directly.
The PCV valve is also designed to open under high
pressure inside the crankcase. This precaution
prevents damage to seals due to over-pressure.[/code]
