The Audi A4 B8 2.0 TDI is one of the most common cars in its class here in Bulgaria. It's comfortable, economical and can serve you well for years if you look after it. Most of these cars have already covered quite a few miles, which is exactly why I want you to understand what needs servicing and when. Because looking after your A4 involves a lot more than just changing the oil and filters. Here's my Audi A4 B8 2.0 TDI service schedule to help you stay on top of it.
Which engine does the A4 B8 2.0 TDI have?
The A4 B8 2.0 TDI uses a common rail diesel engine from the EA189 family. It has a timing belt, a DPF and an EGR valve. You'll find the exact engine code in your service book. That code tells us precisely what needs servicing, so we're not making guesses about your car.
Audi A4 B8 2.0 TDI service schedule: when should you change the oil?
My advice is to change the engine oil and oil filter every 10,000 km or once a year, whichever comes first, regardless of the oil used. The oil must meet VW 507.00 because of the DPF. Trust me, this is one area where cutting corners simply isn't worth it.
Which gearbox do you have, and why does it matter?
You'll come across three types of gearbox in the A4 B8 2.0 TDI, and each has its own servicing requirements. Here's what I want you to know:
- Manual gearbox — we check the clutch and dual-mass flywheel.
- multitronic with front-wheel drive — we change the gearbox oil every 60,000 km using genuine oil. If it starts juddering, we diagnose the problem first. We don't just throw parts at it and hope for the best.
- S tronic 0B5 with quattro — a seven-speed DSG with wet clutches. It uses two separate oils: one for the clutch and mechatronic unit, and another for the gears themselves.
After every automatic gearbox oil change, we always carry out an adaptation. That's part of servicing the gearbox properly, not an optional extra.
What else shouldn't you overlook?
Apart from the engine and gearbox, there are a few other important things I want you to look after before they cause trouble:
- The timing belt, together with the rollers and water pump.
- The fuel filter, air filter and cabin filter.
- The crankcase ventilation filter — every 80,000 km.
- Brake fluid — change it every two years.
- Coolant — change it every third heating season.
Which areas need extra attention on the A4 B8?
There are a few areas on these cars that we always inspect more carefully. I want you to keep an eye on them too:
- The EGR valve and DPF — especially if you mainly drive around town.
- The dual-mass flywheel — we listen for that characteristic rattling noise when you switch the engine off.
- The front suspension arms — as the car gets older, they can start knocking.
With the S tronic 0B5, we never change just one of the oils. This gearbox uses two separate oils, and both must be changed every 60,000 km using genuine oils. Skip one, and the gearbox starts wearing unevenly. I'm telling you this because, when something goes wrong, the repair bill comes out of your pocket, not the workshop's. And that's exactly what I want to help you avoid.
A tip from Kris Mladenov: If you've got your eye on an automatic A4 B8, find out whether it has multitronic or S tronic before you buy it. Believe me, that's no small detail. They need different servicing, and the risks are different too.
If you drive an A4 B8 and have no idea what's been done to the gearbox, come and see us at Das Auto Service. We'll identify exactly which gearbox you have and explain what needs servicing. No unnecessary parts replacements and no guesswork.

It depends on the version. You could have a manual gearbox, multitronic with front-wheel drive, or S tronic 0B5 with quattro.

Two. One lubricates the clutch and mechatronic unit, while the other lubricates the gears. Both need changing every 60,000 km using genuine oils.
