Audi TT Audi TT Body and Interior Systems 1 — Questions and Answers
Question 1: What type of roof mechanism does the Audi TT Roadster (MkII) use for its retractable soft top?
- Manual folding only
- Electro-hydraulic power soft top (Correct answer)
- Electric motor with no hydraulics
- Pneumatic actuator system
Correct answer: Electro-hydraulic power soft top
The Audi TT Roadster MkII uses an electro-hydraulic system with a pump and actuator cylinders to raise and lower the soft top.
Question 2: On the Audi TT, what component prevents moisture from entering the cabin when the soft top is lowered?
- Trunk floor seal
- Tonneau cover with integrated weatherstrip (Correct answer)
- Rear diffuser seal
- Quarter-glass weatherstrip only
Correct answer: Tonneau cover with integrated weatherstrip
The tonneau cover, which folds over the stowed soft top, includes a weatherstrip that seals against the body to prevent water intrusion.
Question 3: A technician finds the Audi TT convertible soft top stops mid-cycle and will not complete the closing sequence. What is the first diagnostic step?
- Replace the hydraulic pump
- Check for fault codes in the convertible top control module via VCDS (Correct answer)
- Manually close the roof and reset the module fuse
- Inspect the hydraulic fluid reservoir level
Correct answer: Check for fault codes in the convertible top control module via VCDS
Scanning the convertible top control module with VCDS will reveal position sensor or limit switch faults that cause mid-cycle stops.
Question 4: What material is used for the Audi TT MkII Roadster soft top fabric?
- Vinyl with foam backing
- Multi-layer SONNENLAND or Twillfast fabric with acoustic layer (Correct answer)
- Single-layer canvas
- Hard composite panel
Correct answer: Multi-layer SONNENLAND or Twillfast fabric with acoustic layer
The Audi TT Roadster soft top uses a multi-layer fabric (such as SONNENLAND or Twillfast) with an acoustic insulation layer to reduce wind and road noise.
Question 5: When replacing the Audi TT door window regulator, what must be done before removing the door panel?
- Disconnect the battery and wait 30 minutes for airbag capacitors to discharge (Correct answer)
- Remove the side mirror only
- Drain the door cavity water drain
- Reprogram the window regulator in VCDS first
Correct answer: Disconnect the battery and wait 30 minutes for airbag capacitors to discharge
The door contains a side curtain airbag; disconnecting the battery and waiting 30 minutes allows airbag capacitors to discharge before removing the panel.
Question 6: What is the correct procedure to calibrate the Audi TT power window after regulator replacement?
- No calibration required
- Close the window fully, hold the up switch for 2 seconds until the window bounces slightly, then release (Correct answer)
- Use VCDS basic settings to reset the regulator
- Remove and reinstall the door panel to trigger auto-calibration
Correct answer: Close the window fully, hold the up switch for 2 seconds until the window bounces slightly, then release
After regulator replacement, the window must be fully closed and the switch held up briefly to allow the control module to relearn the end-stop positions.
