Audi A7 Turbocharger Oil Strainer Failure
Most affected vehicles
Audi A7 3.0 TDI & 3.0 TFSI (2010-2017, CDUD, CLAA, CRTD, CTSA)
Failure mileage range
60,000 - 90,000 miles
Typical failure window
Root cause
The factory-fitted turbo oil strainer mesh is too fine and prone to clogging with carbon deposits, starving the turbo of lubrication and causing bearing seizure or catastrophic turbo failure.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - Updated Strainer & Turbo Inspection | £1,800 - £2,500 | £1,100 - £1,600 | Removing turbo housing, replacing mesh strainer, cleaning oil galleries, pressure testing | Viable only if caught before turbo bearing damage; extends original turbo life |
| Full Replacement - Rebuilt Audi A7 Engine + New Turbo | £5,500 - £7,500 | £3,800 - £5,200 | Complete engine swap with factory-updated oil strainer, bench-tested rebuilt V6, supply & fit | Permanent solution; eliminates secondary oil starvation damage, 12-month warranty |
Our recommendation
On a 2012-2015 Audi A7, the oil strainer recall is a known failure trigger. If your turbo is already making whining noises or losing boost, a simple strainer swap won't fix internal bearing wear. We recommend comparing full Audi A7 engine replacement quotes at this stage, as the rebuilt unit includes the updated strainer as standard.
