Wiper arm chafing the brake booster vacuum line (2012-13 recall)
SeriousBrakesA peculiar but genuine Volvo fault that DVSA recorded for these model years: the wiper arm mechanism can chafe against the brake booster vacuum line, gradually reducing brake assistance or - worst case - losing it suddenly, with the fix being rerouting/adding protection to the pipe. It illustrates the V70's wider recall story that Auto Express summarises (multiple recalls, otherwise solid reliability). Check the recall status of the exact car and inspect the pipe at the scuttle for wear marks.

- Lift the wiper arms and look at the vacuum pipe route for chafe marks or fresh loom tape
- Confirm the recall remedy in writing via the DVSA service
- Feel for a progressively hard pedal during the test drive, especially at the first stop
