Costs are estimates and vary by location, shop, and vehicle condition. Dealership pricing may be higher.
German turbocharged engines typically need spark plug replacement every 30,000-40,000 miles — more frequently than naturally aspirated engines.
$100 – $350
VW/Audi 2.0T engines eat ignition coils. Keep a spare in the trunk. Genuine Bosch or Eldor coils are recommended over cheap aftermarket.
$150 – $400
The EA888 2.0T (2008-2014) has a notorious timing chain tensioner that can fail catastrophically. The chain is at the rear of the engine, requiring engine removal for service — a $3,000-$5,000 job.
$500 – $2,000
VW/Audi water pumps are integrated with the thermostat housing on many 2.0T models. The plastic housing cracks, causing coolant leaks. Budget $400-$900.
$300 – $1,000
VW/Audi thermostats are often integrated into the water pump housing. When the housing cracks, the thermostat is replaced along with it.
$150 – $400
German luxury cars use cartridge-style oil filters that sit inside a reusable housing. The filter element costs $8-$15. Make sure the O-ring on the housing cap is replaced with each change.
$5 – $20 (part only; included in oil change cost)
The A4 is best bought as a 2017+ B9 — the updated EA888 Gen 3 engine fixed the oil consumption and timing chain issues. The interior is gorgeous and Quattro is excellent in bad weather. Avoid 2009-2013 B8 models unless the timing chain has been replaced — it's a $3,000+ job. CPO with remaining warranty is strongly recommended. The S4 (2018+) with the 3.0T V6 is an incredible sports sedan.
