Fuel rail pressure sensor high on Audi — 2.0 TFSI / TDI sensor failure (false high reading).
Audi P0193 — Fuel rail pressure sensor high on Audi — 2.0 TFSI / TDI sensor failure (false high reading). Typical UK independent garage cost: £150–£380.
What actually causes P0193 on a Audi
Audi P0193 is normally the rail pressure sensor itself reading falsely high — sensor is £120 and bolt-on. Always confirm with a second scan tool before condemning.
Audi engines that log P0193
- 2.0 TFSI EA113/EA888
- 2.0 TDI CR
- 3.0 TDI V6 CR
How we diagnose P0193 on a Audi
- Cross-check rail pressure with second scan tool
- Sensor connector inspection
- Replace sensor
- Re-test under load
The common misdiagnosis to avoid
Replacing the HPFP for P0193 is a £900+ mistake — sensor first, always.
Audi P0193 repair cost in the UK
Expect £150–£380 including parts and labour at an independent garage. Main-dealer quotes on Audi are usually higher for the same job, and the spread exists because the cheap cause and the expensive cause throw the same code — pay for the diagnosis before you pay for parts.
