Hi, like lots of other owners I've had egr problems and done the usual things which have worked for a time. My model is an 04 reg 1.6tdci and Its done a lot of miles. (150,000)
The main frustration has been not starting on occasions. Eventually I made and filled a blanking plate and the car now always starts. However, as most will know, because the egr on this model is electronic, the ecu thinks there is a fault and so the engine management light stays on. The fault code reader says there is a problem with the egr!
While trawing through the internet I came across a website for Vauxhall's where they have available a device called the EGR Cheater. Its an item that plugs into the wiring and tricks the ecu into thinking that the egr is working correctly. Check-out www.z22se.co.uk
I wonder if anyone using this site has the know-how to design one for the c-max? or does anyone know of one available already.
I have a 2006 1.8 petrol which as done 50,000+ MIL lights comes on and off have scanned for fault codes and initially got P2008 Intake Manifold runner control circuit open/bank 1, but have also had code P0400 Exhaust valve recirculation flow which would suggest an EGR valve fault, but is the first faulta symtomof the second. These faults do not seem to affect the running of the engine at present. Has anyone had a similar experience that might suggest the next move? Also if I replace the EGR valve does it need to be programmed?
You'll find a couple of previous post regarding the P2008 Intake manifold runner. It's to do with a valve / motor that alters the length of the inlet manifold depending on engine speed in respect of "pulse tuning"
Not certain if the two are directly connected but I don't think we've had many sticking EGR valve problems with the petrol engine versions YET!!!!!
