Did this on the Freelander we had but that was the vac operated type too. As far as MOT is concerned, you can't see them as they are under the cover and the tester can't remove that. However, as far as my car is concerned the EGR is in fault (drove it last night and it was fine on the way out but after the 3rd start the EML came on). A tester will definitely notice the EML
. So the net result of this latest fail is that my EGR is failing and blanking it was a folly as. So my choices now are: Replace the EGR(s) or replace the EGR tubes (for aesthetics) and map them out which is cheaper than the replacement. The dilemma there is then a moral one, I don't care if they are mapped out but the next owner might so I'd have to confess to doing it but that all still hinges on an emissions test.
I'm going to be putting a pair of EGRs in this aren't I? [sighs of acceptance]
