Does anyone know if the oil filter in the 900 is the same part as the 850?
I found a filter in the shed with a part number 4X7-13440-90, which one site I found suggests is for an 850, but I can't find a site listing parts for both 850 and 900 to know if it's the same. I'm assuming they're different but figure it's worth checking seeing everywoner I've found online seem to want €7-€10 postage for a new one!
Surprisingly Amazon seem to be the cheapest place to buy oil at the moment.
