Right following on from previous thread [car/spanner light] that is now out, done know what happened over night but its gone, now its the exhaust emissions light, ive took out the egr and gave it a good clean, i havent drilled into it as per guide as there doesnt seem to be a problem with the bit coming in and out, cleaned down all the other bit. Also cleaned boost sensor and going down the list.

Whats happening is driving fine, but at times just sluggish at low revs, then all of a sudden getting power so to speak and car drives normally. Any ideas? as said im searching the forum as we speak, just if anyones here now and has advice be a big help
