Hi, most helpful once again. Cheers..are those part no.s quoted for the longditudinal mounted engine ie a4 , as I searched the 052 and 053 and they show up for the a4 and the a3, which I thought was transverse ?? I'm not doubting you, just dotting I's and crossing T's. Thanks again

 

Not sure which is the A4 number, i just put up all the new turbo numbers. Like i said, just make sure its off a 01+ A4 or passat and it has a 8 blade compressor and your good
