2002 Audi A6 C5 Quattro 2.5 TDI V6
Runs great if well serviced, but costs are quite high and engineering quality is sometimes saddening
Power steering - repaired, and another repair is coming.
Motor - to do soon, as the engine is rattling like an old Mercedes.
One broken front coil - changed together with the shock absorbers.
Dashboard speedometer went crazy - changed, but the computer LCD goes blank when warm.
Blower makes chirping noises at certain RPM.
A/C radiator ventilator connector failed - fixed.
Locks freeze in winter - doors won't close.
Turbo repaired, still works strange.
Duel pump electronics failed (a common problem for Audi diesels) - repaired.
Now rusts very badly, a repaint is coming.
The car is not a gas guzzler.
At higher RPM it pushes you into seat like a jet fighter.
The ride is very soft and silent.
Simple repairs e.g. brakes are not expensive. But the rest is luxury and expensive: Front suspension parts must be changed A to Z, otherwise the parts will fail one after another. One wheel = 6 parts, full repair (both wheels) with good parts = 400 eur.
The V6 engine is quite known for camshaft wear; camshafts + parts - 400 eur.
Camshaft cover or whatever it's called - 50 eur, and a V type engine requires 2.
Power steering repair - 350-600 eur.
New (restored) turbo - 300 eur.
Fuel pump repair - 100 to 300 eur, depending on the problem.
Shock absorber - 50 eur.
Coil - 30 eur.
Heating coil - 20-30 eur, needs 6 pieces.
A used dashboard costs 8 eur.
The motor, if taken care of like a baby (6.5 liters of good oil, strictly no delays with change!), will run extremely well, but if not - you better have your wallet full and ready.
If you want to buy a diesel - look for a 1.9 TDI PD, because 2.5 TDI V6 repairs are like repairing camshafts on two engines (V type).
Also avoid the Multitronic gearbox at all costs, or the costs will be high!
And I'm surprised at the amount of rust, as cars of '02 were supposed to have a zinc coating. I expected a better workmanship of Audi engineers, as freezing locks, failing fuel pumps, eroding camshafts, complicated suspensions, failing Multitronics, and blanking LCDs makes one doubt the "German quality and reliability".
I would buy another one though, if repair costs were smaller and problems were fixed, because, if properly serviced, the car will run very well and long.
Would you buy another car from this manufacturer? Don't Know
