hi, i got 09 q7 3.0TDI my car wont start and i checked everything there is no problem with anything except the battery my perivous battery didnt have a BEM code so do you think if i changed the battery to a one with a BEM code the car will start ??? becouse i changed every thing that may lead to suche a problem i changed glow plugs,starter, i checked every single wire but the car wont start its only cranking ....... and with all of this problem the engine light is off .... so i cant diagnose anything ...... and when i jump start it with dual battries it will start 90% of times and when it started the engine is perfect and it runs perfectly?
