hello. my edu recently broke on ma van i got a second hand one fitted it all was fine for 75 miles. now when ever i go over 70 sometimes 80 or 90 the eml light comes on and i loose power. sometimes it stays on while driving and sometimes it goes off this has gone on for 400 miles now and still i cant find the problem. the ecu code is p1125 which on autodata says is the (turbocharger (tc) wastegate regulating valve).
anyone had this problem or a similar one so i can try to work it out.
