Known issues and risks
Listed from most frequently reported, each with its source.
Oil leaks and excessive oil consumption
Often reported
Audi A5 problem collections report oil leaks (e.g., engine gasket or rear main seal) and excessive consumption. Some cases are linked to PCV system failures that increase internal pressure and stress seals.
Engine Internal
Timing belt/chain (tension/wear)
Often reported
On 2.0 TDI engines, the timing belt or tensioner components can stretch or wear, causing abnormal noises and, if neglected, serious engine damage.
Timing chain
DPF clogging
Often reported
In city driving, the 2.0 TDI's DPF tends to clog on short trips as regenerations cannot complete. This causes power loss, warning lights, and may require forced regeneration or DPF replacement.
Exhaust Emissions
Dirty or faulty EGR valve
Often reported
On these diesel engines, the EGR valve is prone to soot and carbon buildup, which can hinder valve operation, causing rough running, black smoke, unresponsive engine, and sometimes the check engine light.
Exhaust Emissions
Injector issues (clogging/wear)
Often reported
Common rail injectors can clog or wear, causing hard starting, rough idle, power loss, and the check engine light. Cleaning or replacement is often needed and can be expensive.
Fuel System
Turbocharger failure or wear
Often reported
The turbocharger may experience bearing wear, damaged vanes, or oil leaks, leading to power loss, abnormal whistling noise, increased oil consumption, or exhaust smoke.
