Still not running properly
Well its still not running as it should. Ive changed coilpaks, plugs, MAF, air filter. Starting to look towards a boost leak or possibly a faulty diverter valve.
Can anyone tell me where the diverter valve is in a B6 A4 1.8T engine and if theres any way to determine if its shot by visual inspection?
Also something Ive noticed is when I used to switch the ignition off I would get a winding down sound which I allways asumed was the turbo spinning down. It doesnt seem to do that anymore although I can hear/feel the turbo whistle and kick in while driving still so I asume its working ok. On a side note to that, I was in my mates non turbo clio last week and when he switched the engine off it made the same noise Im refering to above, so perhaps its not the turbo Ive been hearing all along.
