Parts for your 2019 Audi Q5-Manifold gasket

2019 Audi Q5 manifold gasket: what it is, where it fits, and when to replace it

Based on Audi’s own technical references, a manifold gasket is relevant to the 2019 Audi Q5. The Audi parts catalogue (ETKA) lists intake manifold gaskets for FY-series Q5 models with the 2.0 TFSI and 2.0 TDI engines, and Audi Self-Study Programmes for the EA888 Gen 3B (2.0 TFSI) and EA839 (3.0 TFSI in the SQ5) note that the exhaust manifold is integrated into the cylinder head on many petrol variants. That means there may be no separate exhaust-manifold gasket on those petrol engines, but there is still an intake manifold-to-head gasket (often a moulded rubber seal) that does the sealing work under the bonnet.

On a 2019 Q5, the manifold gasket’s job is simple but crucial: it seals the intake manifold to the cylinder head so only metered air gets into the engine. A healthy seal keeps idle smooth, trims in check, and fuel economy on-song. Where a traditional exhaust manifold is used (more typical on some diesels), a dedicated exhaust-manifold gasket keeps hot gases contained and the turbo spooling sweetly.

There’s no fixed kilometre interval for replacement, it’s a “replace-once-disturbed” or “replace-when-leaking” item. Any time the intake manifold is removed—say for runner-flap service, carbon clean, PCV work, or a thermostat/water pump job—best practice is to fit a new OEM gasket and follow Audi’s torque sequence. Avoid generic sealants unless the workshop manual specifically calls for them.

• Typical leak symptoms: rough or high idle, a tell-tale hiss, lean codes (e.g., P0171), misfires at cold start, or a diesel with soot traces and a whistle under load.
• Good servicing habits: inspect the manifold mating surfaces, replace brittle vacuum hoses, smoke-test the intake after reassembly, and carry out throttle/idle adaptations if required.

Owners in Australia and New Zealand can expect straightforward replacement on the 2.0 TFSI/2.0 TDI when the manifold is off. On petrol Q5s without a separate exhaust manifold, attention shifts to the turbo-to-head seal and related hardware. Sticking with genuine or OEM-equivalent gaskets and fresh fasteners keeps the Q5 running reliably and helps prevent repeat work down the track.

Popular questions about the 2019 Audi Q5 manifold gasket

Does a 2019 Q5 have an exhaust manifold gasket?
For many petrol Q5 engines (EA888 2.0 TFSI and EA839 V6), Audi integrates the exhaust manifold into the cylinder head, so there isn’t a traditional exhaust-manifold gasket. There will still be sealing rings or a gasket at the turbo-to-head interface. Some diesel variants may use a separate exhaust manifold with a multi-layer steel gasket—check by engine code.

What are the signs the intake manifold gasket is leaking?
Common hints include a rough or high idle, a faint hissing noise, lean fuel trim codes, or misfires on a cold start. On diesels, soot marks around the manifold area or a sharper whistle on boost can give the game away. A smoke test under the bonnet is a quick way to confirm an intake leak.

How much does replacement usually cost in AU/NZ?
For a 2.0 TFSI or 2.0 TDI, budget roughly AUD/NZD $250–$600 at an independent workshop when done alongside other intake-off work, labour is the big factor. If the manifold must be removed solely for the gasket, costs can climb with extra labour and new fasteners. Genuine parts and proper torque procedures are worth it.
