Classic & Sports Car – Buyer’s guide: Audi TT (Mk1)

Why you’d want an Audi TT (Mk1)

Based on a shortened VW Golf 4motion platform and aimed squarely at the Porsche Boxster market, the TT was a brilliant derivation of the hatchback. It featured four-wheel drive and a choice of 1.8 turbo engines at first, later joined by a 3.2-litre narrow-angle V6. 

Great looks and 2+2 Coupé or two-seat Roadster bodies were combined with Boxster-beating performance. Autocar was impressed, describing it as ‘one of Audi’s most engaging machines in recent times… a handling sensation next to its other performance cars… more alive than any Audi we’ve driven since the original quattro’.

The TT soon proved to be more popular in Britain than anywhere else and the range of options increased to include front-wheel-drive Roadster and Coupé with 150PS or 180PS, plus Coupé and Roadster quattro with 180PS, 225PS or 3.2 V6 250PS.

The 225 Coupé quattro was by far the top seller and is generally regarded as the best affordable model today, the V6s and (in particular) the rare lightened 240PS Sport commanding a significant price premium. 

Front-drive versions sold in relatively small numbers and came with five-speed ’boxes instead of the six-speed unit of quattros and the sophisticated Direct Shift Gearbox (DSG) fitted to most V6s. With standard heated leather seats and a power hood, the Roadster is an appealing way to enjoy fresh air motoring. The TT also became a successful racer, Frenchman Laurent Aïello winning the DTM title in 2002.

An early recall on pre-2000 cars to adjust the suspension, fit ESP electronic stability control and a rear spoiler failed to dampen enthusiasm for the model – and neither did the BBC’s Watchdog programme forcing the maker to replace faulty dashpods free on TTs with complete Audi history. It’s one of the vital checkpoints.

A full service record is highly desirable on all complex modern cars, ideally from main dealers or respected independent specialists. Inspect panel alignment, because poorly repaired accident damage will come back to haunt you.

Be wary of modifications: have they been done well, has the car been thrashed, and what extra stresses are being put on other components? 

There should be two keys and an emergency key, plus the radio code. Check that the remote locks and unlocks both doors as well as the bootlid. Also confirm that the warning triangle, jack, tools, compressor and tyre foam are in the boot.

Audi TT (Mk1): what to look for

Classic & Sports Car – Buyer’s guide: Audi TT (Mk1)


See above for trouble spots

Classic & Sports Car – Buyer’s guide: Audi TT (Mk1)


The 1.8 engine’s cambelt, tensioner and water pump should be changed before 60,000 miles or six years (Audi said more, but some broke early). Look for oil leaks around the inlet manifold and the injector ports, as well as the cam cover. Well-maintained units exceed 200,000 miles; a misfire is likely to be a failing coil pack.

Wishbone and anti-roll bar bushes can need replacement at 30k miles on a hard-driven car. Knock may be broken a-r bar sleeves; dear to fix. Springs can snap, too.


Damaged alloys are pricey to replace; up to £500 each for original equipment, but The TT Shop produces a set of four 18in replica Sport wheels for just under £600.

Electrical problems are common. Check digital fuel gauge against range readout: c400 = full tank, discrepancy may mean a new dash pod (c£1000) or repair (c£300).


Manual clutches can fail at 60,000 miles; the pedal can break at about the same age unless reinforced. DSG on V6s lasts if the oil is changed every 40,000 miles.

Check for bolster wear; cloth trim was standard on Coupés, although many and all Roadsters came with leather – some in dramatic colours such as silver.


Ensure the hood operates smoothly and, if possible, look for leaks (lift carpets); replacement is costly.

Audi TT (Mk1): on the road

Classic & Sports Car – Buyer’s guide: Audi TT (Mk1)
Any TT is quick, with good handling and grip from four-wheel-drive models. Many have been uprated, but check that mods were done by a reputable firm

Despite its high output, the Golf ‘four’ is very tunable; 225s have stronger internals than lesser models, but they can still fail if neglected. Less-powerful units may be substituted, so look for a BAM engine code to confirm that it’s a 225.

The naturally aspirated V6 has a timing chain, which is more durable but can stretch by 100,000 miles, causing a ticking sound; replacement costs more than £1000. Also rev the engine and check for blue smoke, indicating wear: watch the nearside exhaust because the offside opens only on the move.

Coolant temperature should reach 90ºC within a couple of miles of starting from cold and stay there – anything else indicates thermostat problems or worse. Hesitancy and excessive smoke are usually due to a failing MAF sensor.

Maintenance might have been skimped on cheap examples, so go through the paperwork carefully. The Haldex (four-wheel drive) oil and filter should be changed every two years.

The DSG is a superb piece of engineering, but pricey if it goes wrong (mechatronic units costing £1250 to rebuild). The six-speed ’box can function as a normal auto or, in Tiptronic mode, be worked sequentially by paddles or by flicking the lever back or forward – or treated as an automatic that changes up only at maximum revs. Try reverse as well, ideally driving in a circle both ways and listening for untoward noises – there shouldn’t be any.

The same test applies to manual transmissions, along with feeling that the clutch bites at the right level and that all gears engage smoothly.

Make sure everything works – aircon, audio alarm – and look for warning lights that stay on.

The owner’s view

Classic & Sports Car – Buyer’s guide: Audi TT (Mk1)

“I bought my Roadster from a main dealer in ’03,” recalls owner Mike Edwards. “Initially I was disappointed: it was much more modern and quicker than my old Coupé quattro, and the ability to drop the roof helped, but it somehow wasn’t as nice. 12 years on, I’ve got used to its limitations; it’s surprising how much can be carried in the boot or inside.

“I’ve had the clutch pedal snap; I’ve replaced the rear springs four or five times, and most front suspension bushes and joints – all easy DiY jobs. It has rusty arches on one side, which I assume is down to damage before I bought it. I’m surprised how much of the underside has rusty edges: hard to keep on top of, but largely cosmetic. My roof once lost the ability to open and close, and was repaired by the Audi agent at some cost.”

Alfa Romeo GTV (left) and Porsche Boxster are alternative buys


Slightly outclassed by the TT in drivability, the Alfa rival (also 1.8 ‘four’ to 3.2 V6) oozed character, sounded great and housed a fabulous engine. If heart rules head, you might go for this.

A more accomplished sports car, but it’s easy to get caught out with a moneypit in this price range. Intoxicating flat-six sound, plus it’s superb to drive; S reclaimed the performance crown, too.

Audi TT (Mk1): the Classic & Sports Car verdict

Classic & Sports Car – Buyer’s guide: Audi TT (Mk1)

There’s a wide choice of TT models, so understand them and decide which suits you best before going out to look.

As with any well-built modern, problems are few and, because of tight production tolerances, if there are any faults all examples will suffer them. Beware cheap cars; go for one that’s been well looked after – it will save you thousands in the long run.
