2001 A4 2.0 EPC Light

[bwk]

Hello

Recently purchased a 2.0 petrol B6 A4. EML light came on after about 500 miles along with EPC light. VCDS shows fault codes as attached. I know the battery has been replaced recently so ignoring P1602 for now - will clear codes and see if it returns.

Regarding P0321, P0322 - everything I am reading talks about G28 speed sensor (forum posts and RossTech wiki)- but mostly seems to relate to the 1.8T, not the 2.0. When I look on GSF/EuroCarParts I can't see a part which quite ties in with the description of the G28 so hoping someone can confirm or deny which part these codes likely relate to? GSF list a Hall (camshaft) sensor and a crankshaft pulse sensor - I'm wondering if the crankshaft pulse is the place to start?

Thanks in advance

The 2 fault codes that need uncoding relate to engine speed sensor/crank sensor. You also have a fault with camshaft sensor.

Whats the actual problem? Have you tried erasing and driving to see what comes back? Any loss of power? Do you access to any actual values?
