Steve Q Posted February 3, 2022 Share Posted February 3, 2022 My advice would be to get a diagnostic check carried out to see whst fault codes flag up. Also I Know with the S tronic gearboxes if you don't get the oil changes done then this can affect the gear changes. Unsure if this applies to the tiptronic box though. Also it could be the selector module which is failing. Quote Link to comment Share on other sites More sharing options...
