P0741 on Audi: Causes, Symptoms and Fix Cost
Quick Answer
Moderate SeveritySafe to drive (short-term)Audi
P0741 on a Audi means the torque converter clutch is not engaging properly when the transmission control module commands it to lock up. This clutch creates a direct mechanical link between the engine and transmission at cruising speed, and when it fails to engage, efficiency drops and the transmission can overheat.
Typical repair cost, all makes€140 - €1900
Connect any standard Bluetooth OBD2 adapter to your Audi and Skanyx tells you what P0741 means on that engine, whether it is safe to keep driving, and what the fix should cost. Free on iPhone and Android.

Audi A4
2005-2024Only A4s with a torque-converter automatic (tiptronic) can set P0741. The B8, for example, offered a ZF six-speed tiptronic and later an eight-speed automatic, alongside the Multitronic CVT and the S tronic dual-clutch gearbox, and neither of those two has a torque converter. Check which transmission the car actually has before ordering parts.
What causes P0741 on a Audi?
Beyond the generic causes listed on the main P0741 page, these are the patterns noted for Audi models:

How to diagnose P0741 on a Audi with OBD2
Follow these steps to pinpoint the root cause of P0741:
- Check transmission fluid level and condition. Dark or burnt-smelling fluid suggests internal wear that may be preventing the TCC from engaging properly.
- With manufacturer-level software, monitor TCC commanded state against converter slip at motorway speed (a generic OBD2 reader cannot show these values). Slip is engine rpm minus transmission input rpm: with lockup commanded it should fall to nearly zero. If the TCM commands lockup and slip stays high, the TCC is not engaging.
- Check TCC solenoid resistance with a multimeter (typical range 10-25 ohms). Also check for power and ground at the solenoid connector.
- Perform a stall speed test. Higher than normal stall speed indicates the torque converter clutch or converter itself is slipping internally.
- If the solenoid tests good electrically, the issue is likely mechanical: either a worn TCC friction plate inside the torque converter or a stuck valve in the valve body preventing hydraulic pressure from reaching the clutch.
