What Causes Severe Jerking During Audi A6 Acceleration Without Fault Codes?
2 Answers
Audi A6 experiencing severe jerking during acceleration without fault codes is primarily caused by transmission gear programming issues, internal contamination/impurities in the transmission, or poor transmission cooling. When the Audi A6's transmission operates at abnormally high temperatures, it affects transmission fluid performance. If temperatures exceed 120°C, the rubber sealing materials harden, leading to fluid leaks that impact oil pressure and cause jerking. Prompt maintenance inspection is recommended. Additional information: 1. Generally, car jerking occurs due to mismatched engine speed and clutch plate rotation. 2. Frequent gear shifts between 1st and 2nd at low speeds, combined with repeated clutch engagement/disengagement, creates temporary power transmission interruptions - manifesting as common low-speed jerking during startup and acceleration. 3. Normally, turbocharger engagement at low RPMs affects engine rotation speed.
I had a similar issue with my Audi A6—severe jerking during acceleration without any warning lights. It’s likely the transmission acting up. Common culprits in Audis are worn clutch plates in dual-clutch or automatic transmissions, causing this jerking. Another possibility is aged or insufficient transmission fluid, leading to unstable hydraulic pressure and shaky starts. Faulty spark plugs or ignition coils could also trigger jerking, but the absence of fault codes is because the ECU can’t detect intermittent issues. I recommend checking the transmission fluid level and clutch wear—timely replacement can prevent bigger damage. Avoid aggressive throttle inputs; gentle acceleration is kinder to the transmission. Get a professional diagnosis of drivetrain components—don’t just rely on fault codes while overlooking underlying risks.
