yes, i took it to the dealer and they determined a bad fuel pressure sensor/high pressure fuel pump/pcv valve bad. I am totally confused on the quantity of problems that will cost over 1k to fix. not happy
2012 Vw cc 2.0 t Same issue. 2nd time in 4 months. First time "replaced" under warranty : second time had to "clear error codes" they said they "replaced "it how it save an error code? The high pressure fuel pump was replaced and there was a leak on the upper motor- that was all replaced.

I feel it all started with a weak battery. Factory bat is warrantied for 2 years. New oem is warrantied for 5 years with a running core credit. Original battery NO CORE CREDIT. Tell them you will keep it and sure enough your new battery will drop by 40%. It's a parasitic electronic issue giving this car issues.

I bought my 2012 vw cc sport last year. It now has 90k miles on it and I have been dealing with this issue since May. I had all 4 plugs and coil packs changed. Had fuel clearer put into the gas. I only use high octane 93 gas and my engine and EPC light keep coming on over and over. The dealership I took it too cant figure out what is wrong with it. Im thinking carbon build up and now my car is completely out of service. It wont even start and makes a horrible noise when you try too. So if I was you Id take your car the a VW dealership. You dont want to be in the same boat at me.
