Good morning all, I have just removed my decat to have it welded due to a split, all back together now and there is a high pitch wisely noise, i have double checked the lamber sensors are in ok, exhaust is tight , pipes are all on, seems to be around the turbo area, anyone had this before that can point me in the right direction please
Thanks for the reply Xanda73 , I have now finally found the problem , well a mate at rac found the problem, not only has he cleared 4 pages of faults on various things but the purge valve was round the wrong way,
