Audi A5: 3.0 V6 TDI (CAPA/CDUC/CLAB) Intake Manifold Swirl-Flap Motor and Linkage Failure — P2015 (8T)
3.0 V6 TDI (CAPA/CDUC/CLAB) Intake Manifold Swirl-Flap Motor and Linkage Failure — P2015 (8T) is a very common engine fault on the Audi A5 on the 2008–2016 cars, and we rate it major. Putting it right costs ≈A$370 to ≈A$4,140 at independent workshop rates, shown as an approximate guide in Australian dollars. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 26 documented faults on the Audi A5.

What goes wrong
Each bank of the A5's 3.0 V6 diesel has an intake manifold with pivoting swirl flaps worked by a small electric motor through a plastic linkage, and that linkage is the weak point: its joints and end-stops wear loose, the motor overruns its travel, and the car logs intake-manifold position faults (P2015 and friends) with the engine light on. Uneven low-rev running and slightly higher fuel use follow, and because there are two manifolds the 'official' fix — replacing them — runs deep into four figures. The failure is so routine that several specialists sell dedicated repair brackets and linkage kits for exactly this, including suppliers in Australia, which is the affordable path if the manifolds themselves are still sound.
What you would notice
- Engine warning light that keeps returning (intake manifold flap position fault)
- Uneven idle or slight hesitation at low revs
- Marginally increased fuel consumption
- No dramatic driveability change — often the light is the only symptom
How to check it
Where to look. Twin intake manifolds with flap motors in the engine valley, under the engine cover
The engine warning light is the primary evidence, so look at the dash with the ignition on and again with the engine running, and be suspicious of a light that the seller says 'just comes and goes' — that intermittent pattern fits worn flap linkages. At idle, listen for any faint periodic whirring from the top of the engine as the motors cycle. Ask whether the intake manifold flaps, their motors, or a repair kit have ever been attended to, and ask for the invoice; ask an Audi workshop what the fault memory shows before you commit. If a workshop inspection is possible: have the stored fault codes read with diagnostic software — P2015 confirms it — and have the flap linkage play checked at the manifold before pricing either a repair kit or replacement manifolds.
What it costs to put right
≈A$370 to ≈A$4,140 at independent workshop rates, shown as an approximate guide in Australian dollars. That is for this job on its own, not for the car.
Ask the seller
- “Has the engine light ever shown an intake manifold or flap fault (P2015)?”
- “Have the manifolds, flap motors, or a linkage repair kit ever been fitted?”
- “Can I see the last diagnostic report from a workshop?”
Now check the Audi A5 you are actually looking at
Everything above is true of the model, and it is free. What it does not tell you is whether THIS car still has money owing on it, has been written off or reported stolen, what kms it showed in past sale ads, whether it has had accident repair claims and what it is worth today. That comes from the official records for that plate. Enter the plate and its state for the A$17.90 Vehicle Check, or the full history from A$24.99.

Audi A5 buyer questions
Is 3.0 v6 tdi (capa/cduc/clab) intake manifold swirl-flap motor and linkage failure — p2015 (8t) serious on a Audi A5?
We rate it major and very common on the Audi A5. Each bank of the A5's 3.0 V6 diesel has an intake manifold with pivoting swirl flaps worked by a small electric motor through a plastic linkage, and that linkage is the weak point: its joints and end-stops wear loose, the motor overruns its travel, and the car logs intake-manifold position faults (P2015 and friends) with the engine light on.

How much does it cost to fix on a Audi A5?
≈A$370 to ≈A$4,140 at independent workshop rates, shown as an approximate guide in Australian dollars. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.
Which Audi A5 years are affected?
Our research records this fault on the 2008–2016 Audi A5. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.
