Hi all, I'm posting this on behalf of my in-laws. They have a diesel Q5 (2017), which is failing to accelerate intermittently. They've taken it to a local garage who haven't been able to resolve the issue. My father in law believes it may be something to do with the electrics and the stop start function. They are taking it to a local dealer over the weekend, just wondering if anyone has experienced/heard of the same issue? Thanks, James
