Re O rings for C250D

I got replacement O rings no problem for my 94 C250D from my local dealer in Edinburgh, so I'd go back and ask why they don't stock them.

Also, my C250D's leak off pipes, the ones that run between the injectors, were visually OK but when I went to routinely change them (I had air ingress starting issues and this was the last item I changed) the ends that were pushed onto the injector nipples just crumbled in my fingers. Highly recommend you change them as well.

Hope this helps.
