Evening Thank you MrB, much appreciated No I don't have any sophisticated equipment i'm afraid, just DIY hand tools. I've not been able to bench test anything. Everything you say sounds absolutely right - basically everything is working, just not to the exact level as instructed to open/close by. Notably that on engine shut down the valve doesn't shut completely enough (as measured) , according to the position sensor. The light never comes on when running, it's only set when RPM and MPH both = zero. I cant say that we are experiencing any problems. a bit clattery when cold, and the idle can adjust itself up/down slightly and 'wobble', but only occasionally, and it never feels like stalling - just adjusting itself. In fact everything runs fine, other than the flipping warning light. I should probably invest in an OEM valve. Thanks again

Hi I hope someone could help me please as this is driving me mad. We had the engine light come on (dont recall the code) and fitted a new non OEM EGR. Then got an 0409 so changed the valve for an OEM item from a breaker. Still get 0409 after 2-3 switch offs. Freeze frame data says error occurs at 0 rpm and 0 mph. Light then stays on at next start up. Tried a multimeter on the loom, nothing with ignition off, three 'earths' and two at 5 with it on. Not what I thought I'd read, but suggests no broken wires. Tried to look for other causes being 'blamed' on the EGR. Cleaned the MAP sensor (very dirty) and the DPF pressure sensor pipes (clean). Disconnected MAF and got a code for that, but nothing to do with EGR. Start up with EGR disconnected threw up 0405 and 0406 only. Anyone any ideas please - is it EGR number 3? Thanks
