Punto (Mk2/2b) fault codes

[@paynec12.freeserve.co.uk]

P1135 and U 1602, i can reset P1135 but not U 1602. Indication is they are manufacturer specific. has any one know what these codes are or where I can find them on the internet

P1135 is something to do with ambda or cat, not sure. If you clear it and it comes back then it is still a problem.

As for the U1602 that is most likely a connection issue somewhere in the wiring, poor connection or faulty.
