I've discovered a split in one of my vaccum hoses, the one which runs from the back of the bay down the left hand side of the engine and into the manifold (part no. 8L9 612 041 D). The split is just at the 90 degree elbow towards the top of the bay. My question is, is this a dealer only part, or would i be ok to just use some silicone hose with the correct internal id? I noticed the OEM part is quite rigid, more so than the silicone hosing i have, and wondered if this would be an issue?
Cheers!
