Given my current issue [slight burning smell from front, doesn't seem to be coming from DI but making me nervous ...] I was thinking I might pick up a spare DI and plugs to have in the boot. What is the best source?
I note that there a number of eBay sellers offering these for c£90, and claiming that they're the genuine item, quoting the part no. 55559955; but the fact that the demonstrably pukka outlets [Saab dealers] are asking nearer £300 makes me nervous.
