Many of the Tiguans that produce a PO299 code can be fixed by freeing up the Wastegate Lever that often becomes rusted in place. Update... three years later and the code hasn't returned yet!!!!!!
Hi, my wastegate is shut closed tight. The actuator is not holding pressure causing the wastegate flapper to be stucked closed. But I don't know why I am getting a P0299 underboost code. If wastegate is stucked closed shouldn't i be having overboost ? The car runs but has no power slow acceleration. Any help would be greatly appreciated. Thanks
I got a 2013 Tiguan which was leaking oil on the passenger side. Mechanic says its the turbo and I need to replace it. Now this turbo was already replaced back 2 years ago under warranty. Would your your issue cause oil like with that lever. I have no codes.
Update for you... there are two possible sources of oil coming from your turbo. The first is the connection to the oil feed that actually lubricates the turbo. The second is the connection at the intercooler where oil-carrying engine air can collect and possibly leak out.
@@amcrae1 Thanks Alan just saw your replies. I checked the connection at the intercooler and its dry. I found the oil return line leaking through a hole, replaced that still got oil from the turbo. Was told internal seals could be bad. I got a new turbo manifold will replace that and check that oil feed connection first. Thank you.
I just replaced the diverter valve but haven't released the potential frozen lever. Would you recommend anything else if this doesn't get rid of the code? Mechanic is my last resort.
@@amcrae1 the intake valves. Direct fuel injection technology causes the tops of the intake valves to gunk up like crazy because fuel never touches the top of the valves.
