tdci stevie Posted August 21, 2010 Share Posted August 21, 2010 Hi just thought i would start a new thread with added pictures of my problem. When i floor it the rev needle jumps but the car doesnt, if i slowy apply throttle it has plenty of power is do a ton, its the moment a give it a little the car doent respond straihht away. I had to change the big rubber inlet pipe that goes from intercooler to bottom of EGR a while back as loss of power and a hissing noise, so changed that and thought everything would be merry, but not has got rid of hissing noise and slightly improved performance, but still have this boost problem. Have checked the little solenoid vac and pipe (pic 1) for splits and is fine, also getting vaccum from it (when idling) everthing seems to be fine there, chased the pipe to actuator on top of turbo and still no splits (pic 2). I took off the vaccum pipe that goes from vac solenoid actuator and drove it to see what happens and it drives a lot worse....if this test helps Had diagnostic machine put on and there are no stored or pending codes.... Any ideas or help in the right direction would be great.... Quote Link to comment Share on other sites More sharing options...
tdci stevie Posted August 22, 2010 Author Share Posted August 22, 2010 A diagram of the turbo and all associated hoses/vac pipes would be great, haynes manual are sh*t for things like that... And if it was the turbo knackered why when i took vac pipe off acuator it made it a hell of alot worse...? Quote Link to comment Share on other sites More sharing options...
