Cerco aiuto al problema:e91 335i xdrive auto

[carlo977]

Eccomi con gli aggiornamenti...
Sconto casa madre sul pezzo 50%,sconto ulteriore concessionaria 10%,sconto officina manodopera 15%

Tot 1770 IVA compresa.
Va da sè,che a fronte di 1000 euro per. La sola chiusura del motore,faccio il lavoro. Mi faccio consegnare i due alberi a camme,e li faccio vedere ad un meccanico.
[MENTION=99]Franzzz[/MENTION] ,appena me la consegnano,passo. Grazie

Buon risultato,
1770 iva compresa e buono

Lo sconto del concessionario praticamente è quello di norma, dal 10 al 15%
Ma non ho ancora capito cosa è successo di preciso!
Al momento di saldare la fattura portati anche il vecchio conto e fattelo scalare, non è giusto che tu paghi i loro tentativi e la loro negligenza.
In fin dei conti a tue spese si stanno facendo esperienza e questo non è giusto :new_cussing:

Appena mi chiamano,credo in serata,vado. Dubito fortemente che mi scalino il precedente conto. Il 10% della concessionaria è sul pezzo,oltre ad un 15% sulla manodopera

In che senso,non capisci cosa sia successo?
Cosa di intende per swappare?

Sarebbe buono,se mi garantisse la soluzione al problema. Ed invece,non mi garantiscono niente!!!

Non ho capito cosa si è rotto ma il fatto che non te lo garantiscono vuol dire che non lo sanno neanche loro.
Swapp si intende cambiare un motore con un'altro.

Riguardo agli sconti intendevo dire che non si sono assolutamente sprecati, li applicano sempre.

Ciao ma allora il problema cos'era? So di problemi alla camshaft bearing ledge che praticamente si usura e non da abbastanza olio alle vanos. in concomitanza cambiano anche l'attuatore vanos e le solenoidi. Ma e' abbastanza raro. Codici?
il codice vanos l'ho anch'io adesso e mi stanno pulendo intercambiando le solenoidi. Se sono le cammes e' la volta buona che la brucio. Comunque il mio motore e' in garanzia un anno e ho tutta la testa di quello vecchio da intercambiare.

SUBJECT
Power Reduction, FC 2A82 Intake VANOS and/or FC 2A87 Exhaust VANOS Camshaft Faults are Stored in DME


MODEL
E82 and E88 (1 Series) with N51, N52K and N54 engines produced from 1/2008

E90 and E91 (3 Series) with N52 engine produced from 3/2005 through 6/2006

E90, E91, E92 and E93 (3 Series) with N51, N52K and N54 engines produced from 7/2006

E85 and E86 (Z4) with N52 engine produced from 1/2006

E83 (X3) with N52K engine produced from 9/2006

E60 and E61 (5 Series) with N52, N52K and N54 engines produced from 3/2005

E70 (X5) with N52K engine produced from 10/2006

E71 (X6) with N54 engine produced from 1/2008


SITUATION
The “Service Engine Soon” (MIL) lamp is illuminated and a power reduction is clearly perceptible. This situation can occur after driving for some time with the engine already at full operating temperature. If the ignition is cycled, the engine then usually performs normally.

The following faults are stored in the DME:

2A82 VANOS intake – stiff; jammed mechanically

2A87 VANOS exhaust – stiff; jammed mechanically

3100 Boost-pressure control, deactivation – boost-pressure buildup prohibited (N54 only)

CAUSE
The VANOS faults can be caused by an insufficient oil pressure supply to the inlet VANOS adjustment unit. To effectively move the camshafts to the target positions in the specified time and under all engine conditions, sufficient oil pressure supply to the VANOS control pistons must always be available. When the engine operation requires that the VANOS quickly advance or retard the intake or exhaust camshaft, fault 2A82 or 2A87 may be set if the camshaft is “late”, or does not reach the target position. In this situation, engine power may be reduced and a check control message is displayed. The consequential fault 3100 can also be set in the DME fault memory as well.

PROCEDURE

Perform all applicable test plans for the faults stored. A mechanical restriction or electrical failure of the VANOS solenoid and/or the electrical circuit can cause insufficient oil supply to the VANOS assemblies as well. If the results of the test plans are inconclusive then proceed to step 2.



The oil filter cap insert may have been inadvertently removed during the vehicle’s last oil service. If this insert is not installed, it will result in non-filtered engine oil being supplied to the engine, thus possibly clogging or damaging the VANOS solenoids.


Replace both VANOS solenoids and change the engine oil and filter. Drive the vehicle to verify effectiveness. If this repair is inconclusive and the fault returns, continue to step 4.

If the oil filter cap is found intact, it is possible that the camshaft hook ring seals (3) have worn a groove into the camshaft bearing ledge (1), causing a drop in oil supply to the VANOS unit.



Camshaft bearing ledge

Intake camshaft

Hook ring seals



Note the deep grooves worn into the intake camshaft bearing ledge by the camshaft hook ring seals.



Acceptable camshaft bearing ledge – minor wear marks from the rotation of the camshaft are normal.

If the oil filter cap insert is found to be missing, then the entire oil filter housing cap must be replaced (refer to the EPC). If excessive wear to the camshaft bearing ledge is found, it is only necessary to replace the camshaft hook ring seals and the affected camshaft bearing ledge.

Il fatto è che non c'è niente di rotto...questo,è il dramma. Stanno andando a tentativi....a spese mie...

Non dà nessun errore. Quando la porto,non esiste errore,in memoria....quindi,la bmw,prima diceva che erano le vanos,880 euro ,ora,dice sono gli alberi a camme,1770...chissà cos'altro si sognerà...

scusa ma e' impossibile che non ci siano errori. questo motore ha una ECU molto sensibile e appena qualcosa non e' nei parametri ti da l'errore e va in limp mode. Se ti e' venuta la spia mezzo motore codici ci sono. hai su un tuning piggyback tipo procede o bms jb4? forse quelli cancellano errori.
