audi s2 3b fault code 0201

[cinic]

Hi guys
Can you help me with this code? Last week my car began acting strangely (slow accelerating when warm) so I gave it to my friend who’s working at official Bosch service (but not mechanic ) to run for me a diagnostic test (free of charge ). The thing is that when pull this fault code 0201 (see attach.) nobody gave reasonable explication. They say may be its catalyst (recently changed) or exhaust system. After a lot of searching didn’t find anything on internet so I’m asking for your help. Sorry because its in Spanish language but sounds aprox.

0201 Transmitter number of revolutions – Wrong or inexistent signal

Transmitter number of revolutions sounds to me like an rpm sender

Was thinking the same myself, but engine starts normally and when cold accelerate very well. Problem starts when car getting warm I cant feel the turbo kick even.

hi

what about your little valve close to your turbo, pressure valve. Not sure of the name in english
but sounds more like the sensor for rpm.

Suppose that you referring a wastegate . Ill going to check it, but don’t think that it’s the problem.
