Exhaust snapped at the flange from the manifold to first box downpipe. Rest of the exhaust is fine. Thought I would give fellow motorhome fun friends a heads up as with a little bit of care you may be able to extend the life of the pipe; or at least be more aware of an inpending failure. Searching the forum it would appear this has happened to several members also. Strange, but when searched for, this pipe appears to be quite illusive but manage to find one on ebay; £60.00. Also discovered that my 2006 autotrail is a non cat version??? I always assumed it was ??? Easy job for basic DIY as all fastenings are easy to reach, just need the trusty WD40 and good socket/spanner 10mm & 13mm.
