Hi,
I have a Brazilian Kombi T2c (2004 Air-cooled). I know it's Brazilian and a Bus BUT i's still from South America!
I know this is a forum for a Mexican Beetle BUT I was wondering if I could ask for some help?
I am like you and struggle with the lack of information from vehicles from VW Brazil or VW Mexico and have an issue with my fuel injection Flat 4.
The Kombi uses a MP9 ECU but its a slightly more advanced version of the Digifant.
I am having trouble with the following Fault code:
00533 - Idle Speed Regulation
10-00 - Adaptation Limit Not Reached
It is similar to the Beetle code as well.
I am unable to perform basic settings as this fault code is always comes back even after a clear (If I clear at higher RPM it clears and does not come back for some time but not enough)
Do you have any ideas how to do Basic settings with such a fault code?
Do you know any other causes of this code?
I have tried and found NO Vacuum leaks. All sensors (MAP etc) are correct. ISCV is working but rpms drop a little Before coming to an idle.
Thanks
Steve
