Buna ziua tuturor. Am achiziționat recent un BMW 318i, e46, motorizare 1995 cmc benzina cu martor verifica motor aprins. Fostul proprietar m-a asigurat cĂŁ este vorba de sonda lambda, dar când m-am decis sĂŁ o schimb mecanicul mi-a diagnosticat altceva. Este vorba de codurile de eroare P2776 si P278a. Daca ați mai ĂŽntâlnit problema aceasta va rog sĂŁ-mi dați de știre. Care ar fi rezolvarea? Va mulțumesc

OBD II P2776

 

OBD-II Code Tap shifting will be disabled is defined as a Upshift Switch Circuit Low

 

Some vehicles equipped with automatic transmission will give the driver the option of selecting the desired gear while driving, known as TAP Shifting. The shifter will usually either have a + ahd - button on it, or shift side to side when in Drive. If the upshift switch does not function correctly, code P2776 will set and the TAP Shift function will be disabled.

Mulțumesc pentru ajutor. Masina am achizitionat-o de la un samsar din Roman. A avut inițial volan pe dreapta si posibil...cutie de viteze automatĂŁ. Acum are cutie manuala, dar cred ca are ceva senzori pe instalația electricĂŁ ce nu se pupĂŁ cu configurația actualĂŁ. S-a ĂŽncercat ștergerea erorilor, dar nu a mers. Poate ar trebui sĂŁ ĂŽncerc in alta parte?! Oricum, mulțumesc pentru rĂŁspunsuri. Cu stimĂŁ! Edited by roa72
