Yesterday my 2010 Golf TDI went into limp mode and the glow plug light started blinking but since it happened a couple winters ago and was fine the next day I didnt look into it any further. It was around 20 degrees F and the car had sat for a week without being driven. This morning I went out and started it up to allow it to warm up so I could go to work. It started up an I unplugged my block heater (Frost Heater). I did some chores and came back to my car not running anymore. The check engine light was on but it has been for 3 years due to the EGR valve in the exhaust under the car being stuck open. I tried starting it and it would start and immediately die after it fired. I ran the codes and only got P0475 (Exhaust Pressure Control Valve) which is always on as noted before.
After forum searching I checked the battery while cranking and it remained over 10v as it cranked. I checked the fuel filter and pump, it was getting fuel to the filter. I checked the key to make sure it was communicating correctly to the car and it was syncing correctly. I Unhooked the battery for an hour and reconnected it. After doing so it ran for a second and then died and the glow plug light started blinking again. I ran the code and got P0237 (Turbo/Super Charger Boost Sensor "A" Circuit Low) which was the reason for the glow plug light blinking as it did a couple years ago. I never had a problem starting it with the boost sensor fault before so I can't believe it is causing the issue. After this It would not even fire. I reset the code with the scanner and it would start and die a couple times then the boost code came back and wouldn't fire. I started checking the sensors and pushed the car in the garage.
Tomorrow I will check the MAP sensor to see if it is bad and the Boost sensor as noted in a forum...
Is there anything else that anyone would recommend?
Thanks!
