SEAT P0017 repair cost in the UK
Expect £700–£2100 including parts and labour at an independent garage. Main-dealer quotes on SEAT 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.
