egr cooler

hi all

i've got issue with my abs/esp and faulty handbrake, so after connecting to lexia and resetting code, starting car up again i noticed that the abs/esp faults appeared on display and i noticed each time i checked lexia i would have egr faults.

removing the egr was easy, just a pain with all the other bits first to get access to it, i dismantled the egr and cleaned it and noticed to motor felt rough to turn but always sprung back to position.

i took a photo of the egr cooler and this looks blocked....its covered in soot with holes in but the holes only seem to be a metal plate and don't seem to go anywhere, i've not clean it yet as i was going to remove it first

i just need to know if this is normal or should the holes go right through it?

sorry i can't post picture

btw.......i've changed the brake light switch and checked wiring next to battery

best regards
