2014 Volvo V70 2.4L Diesel · PO14 MVE

A 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.

The Owners' Club has V70 threads of post-rain sloshing and rear footwells that fill like a well, and FnF’s Volvo drain guide explains the mechanical cause across the S80/V70/XC70 generation: front drains run through a 90-degree elbow behind the front wheels that clogs or whose tube slips off, and the rear drains discharge into the trunk area. Water in the sill soaks connectors and amplifiers, so the true cost of a blocked drain is measured in electrics, not carpet. Test all four drains before signing.
