Yes the 2nd link is the one, many thanks. Just been to get my car back from a service and I knew there is issue and suspect it's the breather pipe. But they are pushing me towards the MAF part first. Saying the electronics are saying that. But they did t
Say they tried a visual inspection and the hoses seemed OK. After seeing lo action of hose guessing you can't see that on any visual inspection

Try opening the link on a home PC without Tapatalk. It works for me.

Or use old-timer's trick: get a long felxible tube, stick one end in your ear, and poke with the other end under the airbox (keeping clear of moving parts, beers, fans, etc etc....).

You can't "service" the maf, it will be the pipe, maf sensors don't fail on 271.

To the dealer today and bought the pipe and clamps came to about £13 I'm in UK london. Just hopefully can get time this
