The 2008 Audi A4 belongs to the A4 B7 (8E) generation, model years 2006–2008. It is the last model year of this generation and carries the running changes made during production. The engine line-up is the same as in 2007; what differs is equipment and electrical detail, which is why the wiring diagrams are matched to your VIN.

On the EA288 2.0 TDI the particulate filter, AdBlue (SCR) system and EGR cooler are the usual jobs, along with the timing belt. The supercharged 3.0 TFSI is known for coolant pump and thermostat leaks and for carbon build-up; both procedures are in the manual.

On a 2008 car the 10th character of the VIN is “8”, a quick way to confirm the model year before you order.
