Audi Q8 3.0 TDI Service Schedule

What do we check at every Audi Q8 3.0 TDI service?

Engine oil and oil filter – I recommend changing both every 10,000 km or once a year, whichever comes first, regardless of the oil used.
Crankcase breather filter – we replace it every 80,000 km.
A full diagnostic scan of every control module, plus a check for available software updates.
We inspect the brakes, tyres and suspension.
We check the AdBlue system and the DPF.

What should you have checked once a year?

Cabin filters – the Q8 has several, not just one.
We check the air suspension.
We inspect the 48V battery and starter-generator.

Which service items need replacing regularly?

Air filter and fuel filter – we replace both alongside the engine oil every 10,000 km or once a year.
Brake fluid – change it every two years.
Coolant – we replace it every third heating season.
Eight-speed Tiptronic gearbox oil – we change it every 90,000 km, along with the transfer case and differential oils. Afterwards, we always carry out a gearbox adaptation.

What should you know about the engine and timing chains?

The 3.0 TDI is a V6 with its timing chains at the gearbox end of the engine. And there's something important I want you to know. If those chains wear out, we have to remove the engine to repair them. That's why, during a major service, we use diagnostics to check whether the timing chains have stretched. It's much better to know what you're dealing with before it turns into a bigger repair.

When do the Audi Q8 driver assistance systems need calibrating?

Had your windscreen replaced, the front end repaired or a wheel alignment done? Then the cameras and radars must be calibrated. Otherwise, your driver assistance systems might not respond correctly. Please don't skip this step after a repair.

If you get a fault warning for the 48V system, don't put it off. Your Q8 could lose some of its functions, and sometimes it might not even start.

A tip from Kris Mladenov: If you're leaving the car parked for several days, connect a battery maintenance charger. The Q8 is sensitive to a weak battery.

If you drive an Audi Q8 3.0 TDI, book your car in at Das Auto Service. We'll give it a thorough inspection, explain exactly what it needs and won't start replacing parts blindly.
