Hi friend, I have the same problem. Nothing change when the check engine lits on. After cleaning the error it lits on at motorway speeds. Have you fixed the problem? How have you? ThanksI need some help, I’ve posted twice now, maybe in wrong forum, maybe admin can help here. I have a error code of P1493, my dealer can’t sort it out, my local garage can’t help either. It comes back on my obd2 as cap canister purge valve. Again, can anyone on here help me where is it located on a 2014 1.5dci. The check engine light comes on amber, doesn’t affect running at all, and only seems to happen at motorway speeds. I fed up of clearing the error and want a permanent fix. Please please someone help me out. ?
