I have a 2015 GSW TDI with 130k miles that I bought new. So far, it's been great, but for about the last 6 mos, the low coolant light will come on, and I have to add a cup or two of coolant. Couldn't see any leaks, but it was almost due for timing belt/water pump, so I thought I'd see if the new wp fixed it. Still losing coolant, looks like it's blowing out the overflow bottle, but only 1-2 times per month, so I figured I could live with it.
Now I'm heading to Yellowstone with the family, and we have a real problem. Luggage on top, bikes on the back, 75 mph speed limit, and I'm having to add coolant every half hour. Finally the low coolant warning pops up again, the temp guage goes high, and I knew that the jig was up for the GSW. So, I left the car at my sisters house, rented a minivan and went on to Wyoming and Montana. So now I'm back, I towed the car home, and I'm trying to solve the problem. I've seen the coolant loss thread, and it seems to fit with my symptoms until it got really bad and overheated. The explanation seems to be that dpf regens boil some coolant out of the reservoir, resulting in low levels. So is my dpf on it's last legs and frequent regens are causing the problem, or did I just overheat the engine from too much load? Or am I barking up the wrong tree entirely? If the issue is dpf, then a Rawtek delete kit might be the best solution. Any advice would be greatly appreciated, since I really need to get this fixed. I'm assuming a 2015 with 130k miles is out of emissions warranty, and I'm on my own on this.
