My Audi A4 2006 model is stalling while driving initially for 5 minutes and stop in traffic, it gets switched off automatically. Once car is fully warmed after 10 minutes of driving it is not getting stalled. It happened with me 3-4 time in one week and car is regularly serviced and it still has about 6500 kms until next service. Appreciate if anyone can help fixing or identify the cause of this problem, hope its not big issue. Thanks in advance.
