Parts for your 2020 Audi Q5-Manifold gasket

2020 Audi Q5 manifold gasket – what it does, and when to sort it

Referencing Audi’s own technical sources, a manifold gasket is indeed relevant to the 2020 Audi Q5. Audi ETKA parts cataloguing for the FY-series Q5 (MY2020) lists intake manifold sealing rings/gaskets across the 2.0 TFSI (EA888 Gen 3B) and diesel variants, and ElsaPro workshop procedures specify renewing these seals whenever the manifold is removed. On the 2.0 TFSI, the exhaust manifold is integrated into the cylinder head (as outlined in Audi/VW Self-Study material for the EA888 Gen 3), so there’s no separate exhaust manifold gasket on that engine. Diesel and V6 variants retain conventional exhaust manifolds with metal gaskets. Either way, manifold gaskets are in play on the 2020 Q5.

On this Q5, the manifold-gasket’s main job is to seal the join between the manifold and the cylinder head so air (intake side) or exhaust gas (exhaust side) can’t leak. For the common 2.0 TFSI, think of the intake manifold sealing rings as crucial for proper airflow and fuel trims – a leak here can cause a rough idle, hissing noises, lean codes, and higher fuel use. On diesel or V6 models, a failing exhaust manifold gasket can bring ticking on cold start, sooty smells under the bonnet, and even turbo spooling issues.

They’re not a scheduled replacement item, but they’re cheap insurance any time the manifold comes off – for example during carbon cleaning, PCV, thermostat, or injector work. Technicians will typically inspect at service intervals around 60,000–90,000 kilometres if there are drivability concerns, and replace whenever there’s evidence of hardening, flattening, or damage.

• Symptoms to watch: rough idle, lean mixture faults, a whistling or hissing noise (intake), ticking, exhaust odour, or visible soot (exhaust).
• Good practice: always fit new genuine-quality gaskets/seals when the manifold is refitted, clean mating faces, follow the factory torque sequence and specs from ElsaPro.
• Tips for the EA888 intake: the seals are moulded O-rings – don’t smear RTV. Lightly oiling them can help seat without pinching.
• Aftercare: clear fault codes and run a smoke test or live fuel-trim check to confirm there are no residual leaks.

Left unattended, a leaking manifold-gasket can skew fuel trims, trigger the MIL, cook nearby components with hot gas (exhaust), and sap performance. Sorted early, it’s a straightforward fix that keeps the Q5 running sweet and efficient.

Popular questions about the 2020 Audi Q5 manifold-gasket

Does the 2020 Audi Q5 have an exhaust manifold gasket?
On the 2.0 TFSI petrol (EA888 Gen 3B), the exhaust manifold is integrated into the cylinder head, so there isn’t a separate exhaust manifold gasket. Diesel and V6 variants use a conventional exhaust manifold with a metal gasket, which should be renewed if the manifold is removed or if a leak is suspected.

How much does it cost to replace the intake manifold gasket on a 2020 Q5?
In Australia or New Zealand, expect parts in the ballpark of $40–$120 for quality intake manifold seals, plus 1.5–3.0 hours of labour depending on engine and access. Typical workshop totals land around $350–$800, more if combined with related work like carbon cleaning.

Is it safe to drive with a leaking manifold-gasket?
Short trips might be possible, but it’s not ideal. Intake leaks can lean out the mixture and cause poor running or higher fuel use. Exhaust leaks risk hot-gas damage and fumes entering the cabin. It’s best to book it in promptly to avoid knock-on issues.
