The exhaust on my 2.1MV is popping from a teet or nipple on the opposite corner of the silencer to the tailpipe, facing downwards. It's a new thing, so I'm guessing something should either be on it or in it? It would be great to not have to get a new back-box, so does anyone have an idea of what the fix is?
Thanks
Tom

I dont know much about MV vans but they have a lamber sensor and that is where it might go maybe. Your not getting shocking MPG are you (apart from the shocking MPG you usually get from a petrol

Aiden or Neil will be along shortly

Re: Popping exhaust
small threaded boss facing down on the J pipe is for connecting the VW emmisions gear, there should be a cap on it; if I can get the cap off mine you can have it as I have a new J pipe to go on as I now have a 2" hole directly above that boss, in the meantime stick a cork in it to stop air being sucked in as that will cause the lambda to report weak mix and the ecu to run over rich and waste fuel

Re: Popping exhaust
Cheers guys!
The undoings of the van being sat doing sweet FA for a year by the sea are rearing their ugly head at an alarming rate!
Jed, the la-la-la-lambada is tucked up on the underside as I found, as this was my first suspicion too.
Aiden, that would be great, but in the meantime I appreciate such a valid excuse to keep drinking bottles of wine until I find one with a real cork in it!

I'm getting 20 pence per mile on a run in the gassed 2.6 - try and beat that on hypertax derv

Does help that it doesn't weigh 3 tonnes though Jed

that'll be the petrol boys as the diesel turbos go bang out the tailpipe like Andy S's did and that was just a puddle
