Gave up trying to DIY my EGR blanking plate, as I have no wish to try and remove the exhaust manifold to drill out the egr bolts when they snap. Never mind eh! I consoled myself by cleaning the map sensor, definitely a 5 minute job, just got some elctrical contact cleaner from local auto bits shop £7, what a noticeable transformation, seems to pull away smoother and quicker too! Have to swallow the £37 hourly charge for 4x4 local outfit to do the biz with the egr plate. And I s'pose they can do a diagnostic to get rid of the tres amigos who seem to like the warm weather!!
