A3car19tdi Posted July 22, 2023 Share Posted July 22, 2023 Hello. I have this little a3 2009. 1.9tdie. Its had good service and now on 120k. I've had it for 4 years and it's always done this. It has a little very regular shudder when travelling along the motorway at around 60 70 mph. It's like every few seconds there's a little gentle shudder or vibration from the engine I can feel it through the seat and the steering wheel . It's definitely not wheels or the likes because if I dip the clutch and coast along it stops immediately. It doesn't do it under load. Just at a steady constant speed and I can't notice it at high or low speeds. Ring any bells to anyone?. Every else appears fine at th moment.

Steve Q Posted July 22, 2023 Share Posted July 22, 2023 Ha r you had a diagnostic check to see if any fault codes flag up? Could it be a faulty injector? Quote Link to comment Share on other sites More sharing options...
