What changes compared with the 2001 Audi TT
The same engines and the same documented faults as in 2001.
1.8 T 20v engine in the 2002 Audi TT
Names: 1.8T 180 · 1.8T quattro 225
- With caution
1.8 T 20v 180 hp (AUQ, 1998-2006)
180 hp · AUQ
Audi TT owner reports document turbo failures (at 60,000 and 155,000 km) and water pump failures (replaced at 110,000 km and again at 130,000 km on the same car), as well as several mentions of the air mass meter; the Audi A3 with this engine also has accumulated mentions of the air mass meter and ignition coils.[2][3]
- With caution
1.8 T 20v 225 hp quattro (BAM, 1999-2006)
225 hp · BAM
Among the 225 hp Audi TT owner reports collected by Fiches-auto.fr there are several mentions of ignition coils, the air mass meter and abnormal oil consumption (one case at 146,000 km); these are the same weak points as on the lower-power versions, and the sources consulted do not indicate that this version is more prone to them.[2]
Faults that affect 2002 cars
- High severityFrequency: OccasionalTurboTurbo wear and oil consumptionThe 1.8T turbo can fail over time -cases documented on an Audi TT at 60,000 and 155,000 km- and several sources link it to growing oil consumption in the engine itself. It is not the most cited fault, but it is one of the most expensive when it appears.
- Medium severityFrequency: OccasionalCoolingWater pump failureThe water pump is another documented weak point of the 1.8T: a 180 hp Audi TT had to have it replaced twice, at 110,000 and again at 130,000 km. Coolant leaks "in several places" are also described on a Passat with this engine.Appears at around 110,000 km
- Medium severityFrequency: OccasionalTimingTiming chain tensioner noise and wearAt least one owner documents the timing chain tensioner of this engine left unreplaced, with the resulting chain noise, on a Passat with 184,000 km; another report from a 180 hp Audi TT points to a timing problem at 90,000 km.
- Low severityFrequency: CommonIgnitionIgnition coil failureYes: the ignition coils (one per cylinder) are among the most cited faults of the 1.8T, especially on engines built between 2001 and 2003. They cause hesitation, a rough idle and the engine warning light coming on; usually it is enough to replace the coil of the affected cylinder.
- Low severityFrequency: CommonIntakeAir mass meter (MAF sensor) failureThe air mass meter (MAF sensor) fails fairly often on the 1.8T: on the 150 hp Audi A3 it appears in 3 of the 11 reports collected, and it is also documented on the 180 and 225 hp Audi TT. It causes hesitation and loss of power; it is fixed by replacing the sensor.
Faults outside the engine in the 2002 Audi TT
- Low severityFrequency: CommonElectronics and infotainmentInstrument cluster and on-board electronics faults (pixels, ESP and airbag warning lights)According to owner reports collected by fiches-auto.fr (149 for this model), electrical and electronic faults are the most frequently cited non-mechanical category: a cluster display with missing pixels, ESP and airbag warning lights coming on and erratic temperature sensors.
- Low severityFrequency: OccasionalElectrical systemAudi TT 8N electric window misalignment and failureAccording to owner reports collected by fiches-auto.fr (149 for this model), the electric windows can go out of alignment and a window may get stuck; the page records it in 8 cases.
- Low severityFrequency: RareClimate controlAir conditioning gas loss and compressor failureAccording to owner reports collected by fiches-auto.fr (149 for this model), there are cases of air conditioning with no pressure or no gas and of a compressor that failed at 190,000 km.
