Check this by shifting through all gears in Tiptronic mode to ensure there is no hesitation or slipping, as the CVT or Tiptronic transmissions in this era can show signs of wear.
While idling, listen closely to the V6 engine for any rhythmic ticking or rattling, which could indicate that the cam chain tensioners are nearing the end of their service interval.
Inspect the front suspension arms during a test drive; listen for any knocking sounds over bumps, as the multi-link front end is a known wear point on NZ roads.
Test this by ensuring the climate control display is readable and that the air conditioning kicks in cold within a minute, as pixel loss on the LCD and AC compressor health are common observations in these models.
Usually marks the point where cooling system components like the water pump and thermostat may require proactive renewal.
A key interval where the transmission fluid service history should be confirmed, and the suspension bushings typically see their second replacement cycle.
The stage where engine gaskets, particularly the valve cover gaskets, may start to show signs of minor oil weeping.
Confirm the timing belt has been replaced at the appropriate intervals, as this is crucial for the longevity of the 2.4L V6 engine.
Ensure all four tyres are of a reputable brand, as the Audi Quattro/FWD platforms perform significantly better with quality rubber.
Verify that the battery is healthy, as these older Audis can be quite sensitive to voltage fluctuations with their complex electronic modules.
Check the coolant colour; it should be the correct G12/G13 pink/purple variety, as improper coolant can lead to sludge in the heat exchanger.
Inspect the under-body plastic covers to ensure they are secure and free of heavy oil staining.
Estimated repair costs if issues arise
Because the front end of the car often needs to be put into 'service position' to access this, it is a labour-intensive job. If the service history is unclear, it is wise to budget for this to avoid catastrophic engine damage.
The C5 A6 has a complex front suspension setup. Depending on how much 'clunking' you hear over bumps, you might eventually need to budget for a complete control arm kit refresh.
It is quite common for the seals to harden with age, leading to a light smell of burning oil. It is a manageable maintenance item that keeps the engine bay clean and oil-tight.
