2015 VW Jetta TDI S DSG
Hi all, my wife has a 2015 VW Jetta TDI CVCA and it has been sitting since March (she works from home now since the pandemic started). I know cars don't like to sit. First, she called me one day and said the car wouldn't start, the battery was shot, so I replaced the battery. Then a few weeks later, I noticed that it was leaking coolant and after removing a couple covers, discovered that it was leaking a steady stream from the water pump. The car has 77k miles, so I figured it might just be due. I ordered a timing belt kit with water pump and the timing belt tool kit from Kerma TDI. I replaced all the idlers, tensioner, serpentine belt, etc. and it all went very well. We decided to take the car for a ride on Sunday and it drove fine for about 100 miles. As we started up a gradual hill, I noticed a distinct skipping feeling and the glow plug light started flashing. We pulled over, took a peek under the hood and all looked normal. Restarted the car and drove it home. On the way home, the check engine light also came on and the car felt like it was now normally aspirated - no boost. I assume it's in some sort of limp mode. I ordered a VCDS that day and pulled the codes today. I'm wondering if maybe I disturbed something or forgot something while changing the timing belt or maybe it's just another symptom of sitting all year. It's right around freezing outside now and the car won't start.

Side note, the car got all the emissions "fixes" at the dealer.

Any input would be much appreciated!
Thanks, Cortlandt

Well that ain't looking good. You may find this thread helpful:

The vehicle has an Extended Emissions Warranty that runs for 11 years or 162,000 miles from the original in-service date. Please see your VW dealership for additional information including the vehicle's in-service date.

I would suggest you contact your local dealer. I don't know what VWoA's current policy is on TDIs but last time I checked, if the MIL is on and you had the updates completed, then everything gets covered under the extended warranty.

Hi Jef, Thanks for the response! I didn’t realize that there is an extended warranty, but that’s good news!

Update: I tried starting the car to move it and noticed smoke coming from under the hood. It appears to be a fried differential exhaust pressure sensor (03L 906 051B). Does anybody know what might have caused this?

Next step is to get it towed to the dealership, but I thought this was odd. The metal tube looks like it got so hot that it started to melt the plastic clamp attached to the timing belt cover, but there is rubber hose between the sensor and metal tube.
