DSG Transmission Jerking/Hesitation on my 2016 S5

Vehicle: 2016 Audi S5 3.0T Premium Plus

Hello Audi enthusiasts,

I'm reaching out for some advice regarding the transmission in my 2016 Audi S5 3.0T Premium Plus. It has the S-tronic (DSG) transmission, and lately, I've noticed it's been acting up. Specifically, I'm experiencing some jerking or hesitation, especially during low-speed driving or when shifting from 1st to 2nd gear, and sometimes 2nd to 3rd.

It feels like the clutch isn't engaging smoothly, or there's a delay. There's no check engine light, but the feeling is definitely concerning. I'm wondering if this is a known issue with these transmissions or if it points to a specific problem. Has anyone else had similar experiences with their S-tronic?

Any insights would be greatly appreciated. Thanks!

ClearTheCode admin answer:

The S-tronic (DL501/DL382) transmission in your Audi S5 is a sophisticated dual-clutch gearbox, and while generally robust, it can exhibit specific symptoms if issues arise. Jerking or hesitation during low-speed shifts, particularly between 1st and 2nd or 2nd and 3rd, is a known concern.

Here are the most common causes and recommended actions:

  1. Common Causes:

    • Mechatronics Unit Failure: This is the most frequent culprit. The mechatronics unit is the brain of the DSG, controlling clutch engagement and gear selection. Internal electronic or hydraulic failures can lead to erratic shifting, jerking, and hesitation. Fault codes like P17D8 (Clutch Temperature Monitoring) or P17BF (Hydraulic Pump Play Protection) might be present, even without a CEL on the dash.
    • Clutch Pack Wear: Over time, the wet clutch packs can wear, leading to slipping or rough engagement. This is more common in high-mileage vehicles or those driven aggressively.
    • Transmission Fluid and Filter: The DSG requires specific fluid and filter changes at regular intervals (typically every 40,000 miles or so). Old, degraded fluid or a clogged filter can impact hydraulic pressure and clutch operation.
    • Software Glitches: Sometimes, a software update for the transmission control unit (TCU) can resolve minor shifting anomalies.

  2. Initial Steps:

    • Check Service History: Verify when the transmission fluid and filter were last changed. If overdue, this should be the first step.
    • Scan for Codes: Even without a dash light, a professional scan with an Audi-specific tool can reveal fault codes stored in the TCU, which are critical for diagnosis.

  3. When to See a Shop:

    • Promptly: While not an immediate breakdown risk, continued driving with these symptoms can accelerate wear on other transmission components, especially the clutch packs. It's best to address it sooner rather than later.
    • Audi Specialist: Take your S5 to an Audi dealership or a reputable independent shop specializing in European vehicles. They have the necessary diagnostic tools and expertise to accurately identify whether the issue is with the mechatronics, clutch packs, or simply requires a fluid service and adaptation.
