I guess you're reading a fault with VCDS. It may list a sensor number beginning with G. Or post the fault code.

It does indeed have two banks split left and right, but also four (confusing I know and this is where it gets tricky) where each bank is split in to two.

There are four camshaft sensors and they live on Bank 1, Bank 2, Bank 3 and Bank 4.

Bank 3 is the failed on on mine but trying to work out which one this is has been driving me mad lol

The VCDS says Bank 3, part number is the same for all banks so doesn't help.
