Good evening,
i am turning to everyone here that could give me an explanation other then what i have been told so far by 2 mechanics. I have a 2008 Audi A6 C6 2.0 TDI and for the past 2 weeks i keep getting a flashing glow plug light constantly coming up, no EML light though and car also going into a slight state of limp mode. Been already at 2 garages both using a VCDS diagnostic software, on both they got a P0299 fault code "turbo underboost" as a short version. I have changed on the car so far the following; EGR valve, Pressure sensor, Diverter Valve, turbocharger been taken off and investigated (no issues found), changed MAF sensor and finally the fuel filter. If anybody can possibly have any idea of what else could be wrong please help me.
Thank you in advance
