Hi guys , we have a 2015 jetta 2.0 150 tdi bluemotion 29k miles with a strange fault, whilst driving we are getting a judder/stutter from the engine just like a misfire, can happen at any speed over 30mph and any higher gear, manual 6 speed box, can last anything from a couple of seconds to 5 or six seconds and can occur many times during a 130 mile trip. No fault code has been stored and has been into vw main dealers 4 times so far to find no fault. I've posted here as there are more newer golfs than jettas so hoping somebody has had a similar fault. Thanks guys
