Multitudine de erori + pornire grea dimineata

Salut. Am un opel astra H GTC din 2005 , 1.6 benzina si am ceva probleme. Acum ceva timp mi s-a aprins martorul motor si a ramas aprins. Initial am crezut ca e de la EGR. Consumul pare sa fi crescut, a devenit mai puturoasa. De asemenea dimineata la rece pornirea e grea...doar prima oara. Dupa verificari am constatat ca dimineata, inainte de pornire bateria are 12.5V- poate fi de asta cauza pornirii grele? Am intrat cu OP-COM si au rezultat urmatoarele erori, pe care le-am sters; martorul a disparut din bord. De asemenea ma gandesc ca unele din erori au aparut datorita faptului ca am tot scos mufe si sigurante pentru a verifica o alata problema de o am si anume cea cu luminile de la placuta de inmatriculare.

Este un cod foarte ciudat care cu siguranta da batai de cap.
Cauzele pot fi multiple. M-am confruntat si eu cu el, insa nu prea i-am dat de capat.
Inainte sa fac segmentarea se aprindea cam pe la 1500km. Dupa segmentare sa aprins odata, am mai strans suruburile de la clapeta si de atunci nu am mai avut probleme, Dupa 5000km sa aprins iarasi, ultima data sambata prin Craiova.
Desi facusem inca 200km de atunci in mers normal, martorul nu sa stins decat cu opcom-ul.
Acum ma gandesc sa desfac admisia (acum am si zgomotul celebru de diesel) si dupa ce siliconez sa las macar 2 zile la uscat siliconul, randul trecut nu prea am asteptat decat.... sa zic 2 ore.
Daca nu reusesc nici asa, blindez EGR-ul un timp (apropo cat costa anularea lui din soft?)

Cred ca ai probleme cu CIM-ul si posibil cu ceasurile.
Incearca sa faci proba cu alt CIM si vezi daca se rezolva.
