Hey All,
Need some help to solve an issue I’m having with my 2013 Passat TDI with 183,000 miles on it. I’ve had zero issues with the car besides the heater core. Never missed an oil change and did the DSG at 75k and 150k. The car is still driving great and want to keep it as long as I can but can’t afford dumping more money into the car than the car is worth. Here is the background to what’s currently happening.
My check engine light came on a few months ago. When I got it read at the time, the only code that was coming up was P026A Code- Charge Air Cooler Low Efficiency. I brought it to my mechanic, and he mentioned that this may be covered by the diesel recall extended warranty. I brought it to VW to learn that I was outside of the warranty due to my miles. I was planning on bringing it back to my mechanic right away but got caught up with life and couldn’t bring it in right away.
Several months later, I got a “Check Coolant Level” warning when I started my car in the morning. The coolant was low if not empty in the reservoir. I had left over coolant from when I flushed my heater core last, so I filled it back up. When I had the hood popped, I noticed oil on the top and front engine (see pictures in link https://forums.tdiclub.com/index.php?media/albums/2013-passat-tdi-oil-on-engine.14428/ ). I brought it back to the mechanic to have him check about the oil leak, possible coolant leak and the original P026A code. When he plugged the car to his reader, he got the following faults:
Engine Electronics:
My mechanic (German Auto Works in Rockville, MD) was unsure where to start since there were so many that he called VW for some advice. They came back and told him that he would need to replace the Turbo, DPF, CAT, NOx Sensor to start with. He basically told me he can fix it, but it would be an unknown amount to fix it completely with everything going on. He said we can fix it or if the cars still driving well, drive it into the ground.
Now a month later, I’m getting the “Oil Pressure: Engine Off! Owner’s Manual!” warning. It has happened 3 times now the past few days when driving less then 5 miles. With this type of warning, I know it won’t be long until the car is done unless I do something.
I know there is a lot going on but I’m hoping for some insight into what people might think it is, suggestions what I can do to extend the life of the car even if its short term. With the Coolant Leak, do you think it might be getting into the engine and clogging up the filter and burning out the pump? Would an engine flush, new oil filter and investigate if the oil pump is working a good starting point?
Thanks for the help all.

I zip tie it away from it as the plastic shielding was melted and didn't want the wires getting destroyed.
