ECU help fuel in the oil

1
HI everyone
i thought i had it narrowed down to the air flow meter and still think
it amy be however the MECH says a fuel injector has probably stuck
open from a piece of rust or something from fuel tank
had tank or i cleaned tank 3 months ago and have replaced the fuel
filter twice just to be safe.
IS it possible??? that a BAD air flow meter could tell the ECU to tell
the injectors to purt to much fuel thru??? yesterday when test driving
after cleaning grounds etc. Black smoke started coming from exhaust...
van still running, but first time i had seen this.turned enbgiune off
restarted idle not smoke drive 30 meters smoke again.
NOt ready to give MECH maore money till i hear from you all
thanx heaps
hopefully getting closer

Most mechanics know nil about electrical systems.
You might as well find a painter to diagnose the problem.
You need a VW or fuel injection specialist.

Yes!

It could also be one of the temperature sensors.

Do you have a Bentley workshop manual?

Robert,
 
It sounds like this mechanic is guessing.  You need to find a workshop, preferably a VW dealer workshop, that knows the Digifant system that is used on the 2.1 MV engine.  There are standard tests used to refine the search by eliminating the many functions one by one until the faulty function (or functions) is found.  As Phill says, the average small workshop mechanic simply does not have the specific knowledge to analyse the Digifant system.  You are paying for him to guess his way through your problem.  At a knowledgeable workshop, you are paying them to fix it, not guess.   This is fairly well covered in Bentleys in any event.

yes Les you are probably right and i should have, as i should have found your fantastic site sooner also.
he finally has said its the airflow meter and i am alot more smarter about these engines etc.
i have also learned to buy my parts out of the U.S. which has saved me heaps.
hopefully this will fix the trouble
thank you for your patience with my e-mails to the group
