Audi A8
2009–present (D4 / D5) · 3.0 TFSI / 4.0 TFSI Biturbo / 4.2 FSI V8 (D4) · Tiptronic 8-speed quattro
The Audi A8 D4 (2009–2017) and D5 (2017+) are Audi's flagship sedans. All A8 use air suspension — compressor and air strut failure are the most expensive maintenance items (RM 3,000–8,000). D4 3.0 TFSI supercharged: supercharger belt at 80,000 km. D5 3.0 TFSI turbo: 48V mild hybrid system adds complexity. 4.0 TFSI V8 Biturbo on A8 L: highest running cost. Carbon buildup and HPFP are universal TFSI concerns.
Audi A8 Common Problems Malaysia — D4/D5
A8 D4 (2009–2017): air suspension compressor failure (most common, RM 3,000–8,000), 3.0T supercharger poly coupler, HPFP, carbon buildup (3.0T direct injection D5 only). D5 (2018+): 3.0T turbo EA839 + 48V mild hybrid — BSG belt and 48V battery failures. All A8: quattro Torsen diff fluid neglect.

A8: steepest depreciation of any Audi — 55–70% in 5 years. Air suspension future cost is main buyer concern. D4: very cheap to buy (RM 80,000–150,000) but annual maintenance RM 6,000–15,000. D5 3.0T: better residual. S8: niche, poor resale. Malaysia: A8 D4 3.0T is best value-entry if maintained; avoid units with unresolved air suspension.
✅Buying a Used Audi A8 Malaysia — Checklist
Used A8 checklist: VCDS air suspension — compressor fill time (must be under 60 sec), all 4 corner heights equal. Drive over bumps — must not lean or sag. ATF/ZF shift quality. Oil level (V8: check consumption). Service history with correct oil spec. D4 3.0T: boost pressure (supercharger). D5: 48V fault codes. Avoid units that sat for months — air suspension leaks compound.
