Audi Q2 Exhaust System: OEM Part Number
| Front pipe with catalytic converter (petrol) | Genuinely a different part from the diesel front pipe below — confirm your exact engine code before ordering, since petrol variants use several distinct references across the range |
|---|---|
| Front pipe with diesel particulate filter (diesel, where fitted) | A genuinely different assembly from the petrol cat pipe — combines the catalytic and particulate filtration function in one unit on most diesel engines, not sold as two separate parts |
| Centre/intermediate pipe | A genuinely separate section from both the front pipe and rear silencer, confirmed in VW Group's own workshop documentation as a distinct assembly |
| Rear silencer, front-wheel drive | VW Group's own workshop manuals confirm a genuinely different silencer and mounting arrangement for front-wheel-drive cars versus Quattro — the underbody routing differs enough that the two aren't interchangeable |
| Rear silencer, Quattro | A genuinely different silencer and mounting from the front-wheel-drive version above, to clear the rear differential and driveshaft routing |
| SQ2 rear silencer | A genuinely different, larger-bore system from the standard TFSI, and on some versions includes an active valve that changes the exhaust note by driving mode — not a like-for-like swap with the standard rear silencer |
Audi Q2 Exhaust System: The Part That Announces Its Own Problems
Where a lot of Audi Q2 parts fail silently until you spot something visually wrong, this one tends to make noise first — a rattle, a drone, an audible change that wasn't there recently. That's a useful early-warning system if you're paying attention.
Audi Q2 Exhaust System: What It Does
Away from the engine, through the silencer, and often through a catalytic converter and particulate filter before reaching the tailpipe — that's the Audi Q2's exhaust job in three steps. Petrol and diesel versions frequently need different systems entirely, since their emissions treatment isn't the same.

A Genuinely Useful Piece of Context Worth Knowing About DPF Diagnosis — Audi Q2 Exhaust System
If you're facing power loss and heavy smoke, this is genuinely worth knowing before assuming the DPF itself has failed: documented cases on related Audi models describe these exact symptoms traced to a faulty exhaust back pressure sensor giving incorrect readings, rather than the DPF itself, worth checking this cheaper component first.
It's also genuinely worth knowing an important legal clarification: removing emissions control equipment fitted for type approval isn't legal in the UK, regardless of whether a "DPF delete" currently passes an MOT test.
