I have just ordered the blanking plug for my car(stainless steel) and will fit it once I have the stainless steel pipe replaced today. They are also going to clean the EGR valve out too. I thought as I had another pipe for it, I would at least get that done. I have noticed lately that I am getting exhaust fumes in my car, and that it not good? The EGR valve is at the front left hand side of the engine, so I assume it is a Euro 3.
The fault on my car might not be a EGR problem, as the code is P2263 (boost issue). I will get the garage to check all the boost pipes etc going to the turbo. This could be the problem why limp mode keeps happening. This happens whether the engine is cold or hot, accelerating or not.
Thanks for your help.
As above - no point in cleaning out the EGR valve (smaller diameter pipes/ hoses, just the main body that the engine air goes through) as no flow will go through it with the solid blanking plate - you must take the inlet manifold off and clean that out
Again, as above, having the EGR valve at the front left of the engine does not mean it is a Euro3 or Euro4, (mk3 Mondeo diesel) it could be either, (there are several different types/ designs) in fact, if your car is more likely to be Euro4, if your car year is correct on your profile, post up some pictures of your engine - i colud tell you
the pipe leaking can allow exhaust gasses (inc. carbon monoxide) into the engine bay that can find its way into the passenger cabin - not good - it can also reduce the energy going from the exhaust to the turbine, so affect boost, so wait and see if this fixes your problem, and take it from there
