Ok thank you for your intesting informations. So what i will remember , its the same story for a focus mk2 1.8 and 2.0L Blanking EGR is always a good thing with any engine. I was wondering because the 2L is a Peugeot engine , not ford engine.
Fitting a solid EGR blanking plate has advantages for any DIESEL engine, Ford PSA etc
With the advantages of the inlet staying clean, less smoke from the exhaust better performance/ economy, turbo spools faster, etc (turbodiesel), on any diesel engine
Some can be fitted with no problem, on others, the engine management light may come on, some owners choose to run their cars with the solid plates anyway, and ignore it or reset the light with a code reader
There was talk about "limp home mode" being triggered due to a solid plate being fitted, but this was forum scaremongering,(when asked, nobody had this actually happen, they had "heard" about it on an online forum) a faulty (eg- sticking open) EGR valve would cause this, (or a plate with holes beong fitted on a car with a faulty EGR valve) a solid plate would prevent this, a solid plate "fixes" a leaking/ jammed EGR valve by effectively disabling the EGR valve/ system
