Solved failure: Hall sensor was the blame!

[Pegasín]

Hi again, volksmaniacs!

Since December my car turned again in a good machine with fiability.
Finally, the Hall sender was the cause of all my problems.
I didn't want mentioned this news before being sure well...
But now, 1 1/2 months and 500 kms after I can say it.

I was desperate; VAG-COM didn´t detect teh failure, so I took the car to a fuel injection specialist workshop (an official Bosch Car Service), the best of my town (according fame) and once of the Spain top 50 (according internet ranking)...

But 1 1/2 months after, since october to november, they didn´t located the problem . so based by intuition, this forum (Phade, thanks for the help) and consulting with a veteran mechanic, I decided to change the hall sensor ...
Fortunately, Hall sensor has cross reference easily available and only costs 62 €

Also, I cleaned the air valve becouse idle speed ,after the engine basical setting, became unstable at cold temperature...

Now, I'm happy again!!! and my car too
