Loose connections in engine bay


Recommended Posts


I've been trying for a month or two to get to the bottom of a turbo issue in my mk7 1.6tdci. Powertrain and check engine lights come on intermittently although with increasing frequency recently. Ive tried quite a few fuel additives like archoil and also the air intake sprays. Replaced the maf sensor to no avail. I drive on motorway every day with high revs so very little lugging on engine. Scan tool shows turbocharger signal above allowable range.


Today i had a look and found a loose connection and a split hose but cant for the life of me find where they fit. Can anyone help?
