No worries.
For info I have spent a few minutes to dig out a thread on the same subject from Volvospy. This thread includes a link I posted to another website which was one of the first where I read of the problem.
Since first posting the hyperlink a few minutes ago I have realised that it is in a frame so this technique won't work.
So, instead:
Open page
http://www.volvospy.com/frameset.php...ospy_newv70c70
Select "Search this forum" at the top of the page
Enter search string D5 injector
Choose date option "Search the whole archive"
Press Search.
There is only one result so you can't go wrong.
Am most interested to hear how you get on with resolution; my brother drives a D5 - currently working beautifully - just coming up to three years old.
