Hi all ,I have Q7 2007 model 3 litre. I m having starting problem last couple of year. Last year I changed starter motor to brand new Bosch, the problem gone away since a few months ago then it started again , I was doing jump start a few times until it came to the point that even the jump start Would not kicking in, only clicking sound then I bought brand new battery from Halfords and put in. It was working fine. Very powerful start when you turning the ignition but but last few days I start having this starting problem again. It will start sometime just a few attempts but another time it wouldn’t start at all. I have portable jumper starter, I did 4 jump start today. I wish someone could tell me what is the problem. Did anyone had same experience like me?

kind regards

No I didn’t coded the new battery, I didn’t know you have to do it. I throw the original battery away , I just found out that I need BEM code from the old battery, do I need to go to Audi to find out or would it be somehere in the history when Vag Com connected? Or if I need new battery’s BEM code , do I need to unscrew the passenger seat again? Also if I want to it myself which VAGCom I sould get because not every VAGCom compatible with my car. Do you have a link for the one that connects to my Audi easily?

Many thanks

I went to my garage. He told me that not every battery needs coding in fact it was true,when he connected my car to the vagcom in the battery selection part my battery wasn't listed but in the code section he changed the code.so the my battery was code to the car.That day the car started ok but the next day I went to a shop came home then stopped the car and I thought lets give it a try, as soon as I stopped the car waited 30 seconds then tried to restart but again the same problem. No power at all. I don't know what is next to check. Any more ideas please. Regards.

Thank you for Your reply I will get it checked this weekend what you have pointed out and see.
