Parts for your 2019 Audi Q5-Exhaust gasket

2019 Audi Q5 exhaust gasket — what’s fitted and why it matters

Based on Audi factory documentation (Audi erWin/Workshop Manual for Q5 FY: Exhaust system – removal/installation and checks) and Audi’s Electronic Parts Catalogue (ETKA, model FY, exhaust system groups), the 2019 Audi Q5 does use exhaust gaskets and sealing rings at key joints in the system. This includes the turbocharger-to-front pipe/DPF connections and various flanged joints further downstream. Audi technical training material for the EA888 Gen.3 2.0 TFSI and EA839 3.0 TFSI notes the exhaust manifold is integrated into the cylinder head on those petrol engines, so there isn’t a separate manifold-to-head gasket on those variants, however, there are still metal gaskets/V-band sealing rings at the turbo and front pipe. On some diesel variants (EA288), manifold-to-head gaskets are used as well as the usual front-pipe/DPF seals.

In plain terms, the exhaust gasket’s job is to keep exhaust gases sealed inside the system from the turbo right through to the tailpipe. On the Q5, that generally means crush-type metal gaskets or ring seals at the turbo outlet and catalytic converter/DPF connections, plus flat gaskets at any flanged joints. They handle big heat swings, vibration, and pressure pulses, preventing leaks that can cause noise, fumes, and performance or emissions dramas.

There’s no routine “every X kilometres” service interval just for exhaust gaskets on a 2019 Q5. Instead, they’re replaced when disturbed (for example, during turbo, DPF, catalyst or front pipe work) or if there are signs of a leak. The factory guidance in the Audi repair manual calls for always replacing single‑use gaskets, sealing rings, self‑locking nuts and V‑band clamps when they’re removed. Sticking with genuine-spec parts is smart — they’re engineered for the heat and fitment tolerances on these engines.

What should an owner or tech look for? Tell‑tales include a ticking or hissing sound on cold start, exhaust odour around the engine bay or under the car, sooty deposits at a joint, a slight drop in low‑down torque on turbo engines, or fault codes tied to post‑cat oxygen sensors/DPF efficiency. If any of that pops up, get the joints inspected on a hoist. Replacement is straightforward for a workshop: cool the system fully, support the exhaust, undo the clamps/fasteners in the right order, clean the mating faces, fit new gaskets/seals, then torque everything to the spec in the Audi repair manual and recheck for leaks after a warm‑up run.

A quick note by engine: the 2.0 TFSI and 3.0 TFSI don’t use a separate exhaust manifold gasket because the manifold is cast into the head, but they still rely on turbo and front‑pipe gaskets. The 2.0 TDI typically adds a traditional manifold gasket as well. Either way, exhaust gaskets are very much part of a proper Q5 service and any exhaust-side repair.

Popular questions

Does a 2019 Audi Q5 have an exhaust manifold gasket?
On 2.0 TFSI and 3.0 TFSI petrol engines, the exhaust manifold is integrated into the cylinder head, so there’s no separate manifold-to-head gasket. There are still gaskets/sealing rings at the turbo and front pipe/DPF connections. On some 2.0 TDI diesels, a conventional manifold gasket is used.

When should the exhaust gaskets be replaced on a 2019 Q5?
They’re replaced whenever the joint is disturbed (turbo, catalyst/DPF, or front pipe work) or if a leak is suspected. There’s no fixed interval, but Audi’s workshop procedures specify single‑use gaskets, rings, self‑locking nuts and V‑band clamps must be renewed once removed.

What are the signs of a leaking exhaust gasket on a Q5?
Listen for a ticking or hissing on cold start, check for exhaust smell, visible soot trails at a joint, slight loss of boost response on turbo models, or related emissions fault codes. Any of these warrant an inspection and likely gasket/seal replacement.
