Leaks & Noises
My car makes a strange knocking and hissing noise as i turn the car off. I thought it mite be the exhaust hitting the under side of the car or somthing. But ive looked at it and i cant see it moving atall im not sure why its doing it because the car sounds normal when idleing and starts fine and drives fine. But somtimes its makes a strange rumbling noise when i start the car but the rumbling doesnt match the rotation of the engine and i can feel the rumble through the floor but the car knocks everytime i turn the car off but the rumbling only happends once every 10 starts maybe.... Please any ideas i dont want anything to get worse its been like this for about 6 months and has not got worse atall thanks... But i know these engines have nothing but problems so any1 who has got one let me know of any problems you have had so i can try making sure it doesnt happen to mine thanks

take it you have had a look underneath the car to visually check nothing is touching on the exhaust?check the turbo pipes are all secure and not split

No nothing is in the way of the exhaust i will have another look but this is really annoying me now none of the noises are loud but they are more than noticable to me anyway. Its been for a service and 2 egr valve changes and a inlet manifold change but have not noticed anything wrong with it when i have asked advice in vauxhall. But im not sure if the turbo is running on full boost it doesnt feel as fast as it used to unless its just me getting used to the car. Is the any products on the market that might solve these problems. If any of the problems that you think is wrong are the going to cause problems to the car? Thankyou for getting back to me so quickly
