Hi all yet again my engine manegment light has come on again when i got the car 6months ago i had this problem that when im on the motorway the light comes on and the car wont go over 3000rmp. so went to get it fixed nad they said it was the erg boost vavle and the garage i got the car from fixed it. now its happened again i have read that the best thing to do is move the valve its self i was just thinking if ppl think this is a good idea. and if it is also possible to clean it upand move it myself. i really dont want to be paying loads of money out coz we have just had a baby but if thats the only case then i will have to coz i need the car for work thanks all.

greetz tate86,

when considering removing egr (actually it is blocking the valve by putting thermally resistant metal disk cut to fit the contours of the valve at the end of the back door which leads back to the engine - not the one that leads into the exhaust) valve you should know that the symptoms of dirty and dieing egr valve are among the light blinking : less power in lower rpms, lazy, sluggish acceleration and lower diesel injection, which can repeatedly make your stop if you do not press the accelerator pedal enough.
in Serbia, since the ecological aspects of car controls for registering a car are not as high as in UK, and since the egr valve is a bit expensive (starts at some 135 eur ends at some 280 eur, depending on the year and model) , and gets messed up every 100.000 km or so - we usually block the darn thing at some point (usually at some 100-150.000 km of mileage).
the car then gets back its power.
the valve is accessible easily after removing the fuel pump (i think, three screws) , and then you can block it, do not remove it, just block it.
cleaning it will not produce enough effect, and it will get messed up again soon.
though, i must say your symptoms are not as if the egr is a problem.
i had similar problem last fall, i mean the light blinking, and i changed MAF and had MAP sensor cleaned, (some 55 eur - i think that is some 35gpb for the new MAF, and some 2 beers at the pub for my brother helping me clean MAP), still the light sometimes gets on my screen, and i just ignore it, since the car still flies when i press acc. pedal :) and the mechanic said - leave it - it is some kind of custom for that model...
only problem when blocking the egr valve is that if your country has strict exhaust gas control (when paying for registration, or doing scheduled tech controls, i don't know what the legislative about that matter is in UK) you might be banned of using the car since it is polluting more than it should be by factory specifications.
