2010 TDI Glow plug light and DPF light
A few days ago my check engine light came on then went off, a few days later the DPF light came on while driving and the icon said it was cleaning the filter while I was driving after about 15 minutes the DPF light went off shortly afterwards the glow plug light came on and the car was driving with very little power like in limp mode made it home turned car off and restarted the car and the DPF and glow plug light were gone but the check engine light is still on but the car seems to be running fine for the last week with the check engine light, any suggestions as how to proceed with my issues car has 200,000 miles.

Scan it and see what the code is.
Any autoparts store will scan it for free, but to get more info you need a VAG scan tool, the store will just have a generic OBDII scanner.

Nice to hear from somebody with 200k miles on their TDI in USA. Wondering if you've had it very long?
Sure sounds like may be a clogged DPF from mileage and description of symptoms, but you need a VAGCOM capable scan tool to read ALL of the trouble codes. If you don't DIY on your car, a good one is the OBD-Eleven, which integrates with a smart phone; DO NOT purchase the annual subscription required to do higher level coding/mods, and such, and it will function very well as an inexpensive code reader for you. Similar, bluetooth 'dongle' scanner types for this car include the Carista, as well. Of course, if you DIY, you will want the tool that works best; VCDS, by Ross-Tech.
BTW, DPFs can be cleaned, if they are still serviceable otherwise, and there is normally a cleaning port located on the DPF for just that purpose. The Audi dealer and their ilk will normally just tell you the price for a new part, and that it is 'required', etc. You'll figure it out; the scantool is your path to the light (aka 'the truth'), as most third parties see nothing but $$$$ signs when you drive up. Find a reputable, indie repair shop with diesel experience, etc.

If you have any warranty on dieselgate, Covered. If no warranty, It might be better to get a tune and emissions delete. I had a new DPF done free, I don't know the cost if not under warranty but you'd be looking at 2500 for Tune and emissions vs what 1500 or so and still have to deal with adblue at some point in the future

See the first response to this thread; if you don't scan the car fully with the correct type scan tool, you will have no clue as to the extent or underlying cause.
If you replaced DPF 50k miles ago, it shouldn't be clogged IF everything on the car is working perfectly, AND the IF the DPF's automated regen cycles have been running successfully, and IF you are using the correct oil type (specifically designed not to clog up the emissions system's bits) etc. You aren't going to know much until you scan the car for fault codes. It could be just a temp or emissions sensor gone bad, and it often is when you lose turbo-boost. Scan the car and let it tell you what's wrong with it.
