Is the Audi A1 reliable?
Autocar's sister title, WhatCar? publishes a reliability survey each year, and while this generation of A1 did not feature on it, Audi itself ranked 26th out of 32 manufacturers featured in its latest survey, with an overall score of 89.1%. This placed it above Alfa Romeo, Jaguar and Vauxhall.
Yours truly owned an A1, which threw up the occasional electrical issue concerning the alarm and parking sensors. There are, however, some more specific problems affecting a wider range of A1s.
Audi A1 Common problems
Engine: A1s with the 1.6-litre and 2.0-litre TDI engines have diesel particulate filters that can become clogged up if the car is used only for short journeys. Happily, there is an easy fix: simply drive the car at 60-70mph on a motorway for 20 minutes and the warning light should disappear as the DPF clears itself out. On high-mileage cars, the timing chain can become stretched and wear out prematurely. Telltale signs include a whining noise when the engine is cold or powering the car up a hill. Budget around £600 for a replacement.
While the 1.4 TSI is a good engine, its turbocharger has been known to fail. This could cost around £2000 to replace, so check that there’s no black smoke coming from the exhaust or a loud whistle when the engine is under load.
Electrics: The alarm can go off at seemingly random times, and if your A1 is specified with parking sensors and it’s raining, they might think they are closer to an object than they really are. To save yourself from tinnitus, get an Audi dealer to run diagnostics on the electronics.
