Used Audi TT Roadster 2015-2023 reliability

When viewing a used car, always follow our used car buying checklist.

Most TT Roadsters won’t have been driven like Lewis Hamilton's F1 car, but the odd few will have been driven hard (mainly S and RS cars), so watch out for examples that feel slack to drive, with knocking or otherwise noisy suspension, squeaky brakes, a clutch that bites high up the travel of the pedal or manual examples with an imprecise gearchange.

Also be sure to check all the alloy wheels carefully for kerb marks. Light grazes aren’t too much to worry about, but more significant damage or chunks taken out of a wheel suggest it’s hit a kerb quite hard, and that could cause damage to the suspension and require expensive repairs.

There have been quite a few reports of TTs suffering from water leaks, usually caused by the drainage tubes for the roof blocking up and overflowing. These can lead to flooding inside the car that, if severe enough, can cause serious problems with the electrics. It’s therefore imperative to check for signs of water in the car; this could include damp carpets or upholstery, or water stains on the carpets or seats. It’s also vital to check that all the electrics work as they should – including the infotainment system.

Some owners have also reported rattles and squeaks from some parts of the interior trim, so make sure you drive the car you’re thinking of buying with the radio off and the roof up to listen out for any such issues.

Fuel tank

The fuel tank could be damaged in the event of a collision, the fuel tank can be damaged on examples manufactured between 29 April 2014 and 24 May 2019. Find out from your local Audi dealer if your example is affected because it'll need to have a shield installed between the bracket and the tank itself to prevent it from being damaged.

Our data suggests the Audi TT is a very reliable car. It performed well in the 2023 What Car? Reliability Survey, ranking first out of 15 cars in the coupés, convertibles and sports car class. Its reliability score was 98.4%. This proves it's more reliable than rivals like the Porsche Boxster and Jaguar F-Type.

A mere 7% of the TTs reported on had any issues – all relating to the air-con system – and all of those were resolved at no cost to owners. All the faulty cars could still be driven, and only the fact that niggles took up to a week to repair took some of the gloss from the ownership experience.

As a brand, Audi finished 26th out of 32 manufacturers.
