This is for a 2007 D3 S8
Did you ever get this sorted? They should be able to be found on any local parts place. If not contact JHM and ask the sales guys. Companies that still work on these cars would be able to know more on them.
If you’re planning on having your car for a long time then consider FCP Euro. They guarantee them for life. Just pull the old ones off and send them back and they send you a new pair. Worthwhile if you think you’ll have it long enough to need a second set. I didn’t realize it but they even take back used oil in exchange, a friend told me he sends them his used oil and they replace it. They don’t use the oil I use otherwise I’d consider it.
Thank you.
