Well I had paid for two injectors at £40 each to use as stop gaps then get two reconned and so on but whilst mooching on eBay I managed to find a full set of 6 off an A5 for £365
I might still do a leak off test see how many of mine are knackered then sell them on to recoupe some of the cost of the new/used ones, just tensioners and gearbox left to do after this really, then hopefully many miles of enjoyable motoring
