hello i have an 07 Audi a6 3.2L and lately it would only start when it wants to this is what it does when it dont start i turn the key and it cranks fine i let go of key still keeps cranking but it just wont fire i turn the key to off and it stops cranking, sometimes after 5 tries and it starts up sometimes i have to wait 10 mins sometimes it starts right up but lately its been getting worse i scanned it with vag-com no codes for fuel system just some freeze frame codes that wont go away, any help would be appreciated thank you.
