I live in Spain and have a daewoo Matiz which is 11'years old. The engine management warning light gives me the code relevant to a blocked EGR valve, which I have had cleaned but the light is now back on, 3 weeks later.
I have been advised to 'block it off' so that the warning light will not come back on again, clean it again, or fit a new one which is a bit expensive considering the age of the car. I am also told it will do no harm to carry on driving. So, why don't I just carry on running it and get it cleaned just before the next MOT?
