Ok thanks very much for that on the receiver/drier. Yes I have got a replacement compressor but was advised that the system should ideally be flushed as debris from the seized compressor might have got into it.

Has anyone found a suitable new aircon receiver/drier for a 1998 2.5TD? Apparently the original part isn't available. Also has anyone had experience of flushing the aircon system due to seized compressor, if so what is it flushed with? Thanks.
