Bank 1 sensor 1 circuit fault on Audi TFSI — wideband sensor response failure on EA888/EA837.
Audi P0130 — Bank 1 sensor 1 circuit fault on Audi TFSI — wideband sensor response failure on EA888/EA837. Typical UK independent garage cost: £150–£460.
What actually causes P0130 on a Audi
A4 B8 2.0 TFSI: same LSU 4.9 wideband as VW, ages around 80–100k miles. 3.0 TFSI S4: two upstream sensors (one per bank), one fails first, the other follows within 10k miles.
Audi engines that log P0130
- 2.0 TFSI EA888 (A4 B8/B9, A5)
- 3.0 TFSI EA837 (S4, S5, Q5)
- 1.4 TFSI EA211 (A1, A3)
How we diagnose P0130 on a Audi
- VCDS block 32/33 — fuel trim and O2 activity
- S4/S5: check both bank sensors, replace as pair
- Wideband part number LSU 4.9 confirmation
- Bosch OE, VCDS adaptation reset
The common misdiagnosis to avoid
3.0 TFSI — replace both bank sensors together. Also don't fit NTK on Audi; the ECM logs P0133 for slow response on non-Bosch.
Audi P0130 repair cost in the UK
Expect £150–£460 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.
Bob's workshop tip
S4 EA837 — both banks together. Second one will fail within 10k miles anyway.
