2018 Audi A4 S-Tronic Jerking at Low Speeds - Reliability Concern?

0

James R. · rep 0 · May 22, 4:31 AM · 1 replies · solved · Question

Hey everyone, I'm a new owner of a 2018 Audi A4 2.0T Premium Plus with about 45k miles. I've noticed a consistent issue with the S-Tronic transmission, especially when driving at low speeds or in stop-and-go traffic. It feels like the car is jerking or hesitating, particularly during shifts from 1st to 2nd gear.

It's not a violent jerk, but definitely noticeable and concerning for a car with this mileage. I'm worried about long-term reliability. Is this a known issue with these transmissions?

I've read a bit online about potential mechatronic unit problems or clutch pack wear. What should I be looking for, and is there a specific TSB related to this? Any advice on diagnostics or what to tell the dealership would be greatly appreciated. Thanks!

Summary: For 2018 Audi A4 S-Tronic Jerking at Low Speeds - Reliability Concern?, work through these steps on your 2016+ vehicle:

  1. Confirm the symptom — note when it happens (cold start, highway, after fuel fill, etc.).
  2. Scan codes — save all pending/stored DTCs; don't clear until you've recorded them.
  3. Check TSBs & recalls — look up your VIN for open campaigns and known fixes.
  4. Inspect the obvious — related fuses, connectors, fluid level, and recent repairs.
  5. Test the common fix — follow model-specific service procedures; one change at a time.
  6. Escalate if needed — burning smell, no brakes, overheating, or stalling in traffic → shop visit.
