2019 Q5 S Tronic Jerking/Hesitation at Low Speeds

Vehicle: 2019 Audi Q5 Prestige

Hi all,

I'm experiencing some concerning behavior with the S Tronic transmission in my 2019 Audi Q5 Prestige. When driving at low speeds, particularly in stop-and-go traffic, the transmission feels very jerky. It's most noticeable when shifting from 1st to 2nd gear, and sometimes from 2nd to 3rd.

There's also a slight hesitation when I accelerate from a complete stop, almost like it's struggling to engage the gear smoothly. I haven't seen any check engine lights or transmission warnings pop up on the dash yet, but it's definitely not the smooth operation I'm used to.

Has anyone else with a 2019 Q5 or similar S Tronic transmission experienced this? What could be the potential causes?

Jerking or hesitation from the S Tronic (DSG) transmission in your 2019 Audi Q5 is a known concern for some owners, and it's good you're addressing it before any warning lights appear. The S Tronic is a sophisticated dual-clutch transmission, and its smooth operation relies on several components working in harmony.

Here are the common causes and steps for diagnosis:

  1. Mechatronics Unit Issues: The mechatronics unit is the brain of the S Tronic, controlling clutch engagement and gear selection. Faults within this unit, often due to solenoid issues or internal leaks, can cause rough shifting. This is a common failure point in some S Tronic generations.
  2. Clutch Pack Wear: Over time, the clutch packs can wear, leading to slipping or harsh engagement. While less common on a 2019 model unless it has very high mileage or has been driven aggressively, it's a possibility.
  3. Transmission Fluid (ATF) Condition: The S Tronic requires specific fluid and regular maintenance. Old, contaminated, or low transmission fluid can significantly impact shift quality. Check your service records to ensure the transmission fluid and filter service has been performed according to Audi's schedule (typically around 40,000 miles).
  4. Software Adaptation: Sometimes, the transmission control module (TCM) might need a software update or a basic settings adaptation to relearn clutch engagement points. This can often resolve minor shifting irregularities.
  5. Engine Mounts/Transmission Mounts: Worn engine or transmission mounts can exacerbate the feeling of harsh shifts, as they allow more movement in the drivetrain.

When to see a shop: Since there are no warning lights, a diagnostic scan with Audi-specific tools (VCDS or ODIS) is crucial. This can reveal any pending fault codes in the transmission control module (TCM) that a generic OBD-II scanner might miss. An Audi specialist can also check transmission fluid levels and condition, perform a basic settings adaptation, and diagnose the mechatronics unit or clutch pack if necessary. Addressing this early can prevent more significant and costly repairs down the line.
