Hi, I am replacing my kaput AC compressor on an A4 TDi 130 AWX 2003 Avant. I have been advised that the warranty is only applicable if I replace the receiver drier at the same time. I am doing some research - the compressor is easily reachable and I have removed it previously to get the part number. However, I can't find a walk through on replacing the receiver drier. From some research, mostly US sites, it looks like the drier is behind the bumper, next to the condensor, beneath the headlight. Does that mean it's a bumper off job to reach and replace it?

Many thanks for any help.
