Hi Gareth thank you for the reply .I bought the Q7 July last year with 65000 miles ,last serviced 10/07/25 . noticed the slight rattle after a few days when starting up one morning with the door open only on first start up particularly when cold .It’s not any worse now than when I bought it . Recently I put it into a local garage for a leaking injection seal . hasn’t used any oil since last service was only after a conversation with the service manger I was then advised of the complexities of repair . Unfortunately not a job they have undertaken. I wanted to find out more so started asking around and was recommended Audi owners club . If anyone can recommend a competent mechanic /garage to diagnose, and quote cost of repair it would be appreciated.
many thanks
