Parts for your 2009 Audi Q5-Cluth slave cylinder

2009 Audi Q5 clutch slave cylinder — is it used on this model?

For Australian and New Zealand–delivered 2009 Audi Q5 models, a clutch slave cylinder isn’t fitted and isn’t relevant. Those vehicles were sold with either the 7‑speed S tronic dual‑clutch transmission (DL501/0B5) or a torque‑converter automatic, not a traditional manual. Because there’s no clutch pedal and no external hydraulic clutch circuit, there’s no master or slave cylinder to service or replace.

Why that matters: the S tronic uses an electro‑hydraulic mechatronic unit that controls two internal multi‑plate clutches (K1 and K2). The clutch actuation is built into the gearbox and governed by valves and pistons inside the transmission, not by a separate slave cylinder on the bellhousing. A conventional slave cylinder is only found on manual gearboxes, typically as a concentric unit around the input shaft. If someone has a grey‑import Q5 with a 6‑speed manual (rare in AU/NZ), that car would indeed use a clutch slave cylinder—but that configuration wasn’t part of the local 2009 line‑up.

Technical sources supporting this:

• Audi Self‑Study Programme on the 7‑speed S tronic (DL501/0B5) explains internal, electro‑hydraulic clutch actuation rather than an external slave cylinder.
• Audi Q5 (8R) launch/brochure specifications for 2009 in Australia and New Zealand list S tronic (and in some markets a torque‑converter automatic), with no manual transmission offered locally.
• Official parts/workshop information (ETKA/erWin) for AU/NZ VINs shows no clutch slave cylinder listing for 2009 Q5 automatic/S tronic variants.

What owners should service instead: for the S tronic, the important maintenance is regular transmission fluid and filter changes at the specified interval (commonly every 60,000 km for the clutch/mechatronic circuit), checking for mechatronic leaks, and performing adaptation procedures if shift quality degrades. Brake fluid should still be replaced every two years, but that’s not related to a clutch circuit on these autos. If a vehicle is an import with a manual, the hydraulic clutch system (shared reservoir with brakes) should be bled during brake fluid changes, and the concentric slave cylinder inspected if there’s a low pedal, fluid loss, or contamination inside the bellhousing.

If you’re shopping for a “2009‑audi‑q5 cluth‑slave‑cylinder” locally, chances are it won’t match your car’s driveline. Confirm your transmission code (e.g., DL501 for S tronic) on the build label or via a VIN‑based parts lookup to avoid ordering the wrong part.

Popular questions

Does a 2009 Audi Q5 have a clutch slave cylinder?
Australian and New Zealand–delivered 2009 Q5 models don’t. They use S tronic or torque‑converter automatics, so there’s no external clutch hydraulics. Only rare manual imports would have a slave cylinder.

What maintenance replaces a clutch slave cylinder service on a 2009 Q5?
For S tronic cars: change the transmission fluid and filter at the prescribed interval (often 60,000 km), check for mechatronic leaks, and carry out adaptations if shifts feel harsh. Keep brake fluid changes up to date, but that’s separate from the transmission.

How can someone tell if their 2009 Q5 is S tronic or manual?
Look for a P‑R‑N‑D‑S selector (that’s auto/S tronic) and no clutch pedal. The build sticker/PR codes and the transmission code (e.g., 0B5/DL501) also confirm it. Manuals are uncommon in AU/NZ and typically appear only on grey imports.
