We were in the same position fortunately they backed down before it went to FOS, as they couldn’t guarantee us not having the same problem with a like for like we opted for an s3. So I was advised there is a software fix which is awaiting to be developed but until then expect customers to continue with faulty cars! The ironic thing was few days after collecting the s3 the dealership put our old one back on the sales pitch!! Safe to say I won’t be purchasing or taking our current car back to that particular dealership
