163bhp?

i think its mapping up to the 163s then the 180's had a newer map and a ko3s turbo. Also some are dbw, others are DBC. The engines vary from AEB up to around 99 then APU and AJL with various different combinations of management from the parts bin i think
 
There were a mix the 163s were not only in the B6 chasis.
 
Yeah my A4 was a face lift, and i do recall seeing on the paper work in the book that it was 163.
