I bought my 2012 Touareg TDI CPO back in October 2019 with 72k miles. I'm now at 85k miles. Two weeks ago as I was driving the glow plug light came on and the vehicle reduced power. The MIL illuminated shortly thereafter. I brought it to my trusted local dealership where I bought the car and have been using them for service on my other VWs for many years. They provided me with a Tiguan loaner and sent me on the way. I received a call shortly thereafter saying that there was an issue with the fuel system and they would be ordering parts. Fast forward two weeks and they are saying that all the parts have come in except for one and it is on national backorder. I spoke to them this morning and they've escalated to VW, but no timeline for it to be repaired. The dealership has been great, I don't mind the Tiguan and I know I'm not putting miles on my Touareg but it isn't convenient (i.e. can't put the dog in it, it doesn't have a hitch, roof rack, etc. so it isn't easy to travel with the kids). I know there is a lot going on in the world right now and I'm totally understanding, I just have a concern about the fact that parts aren't easily available for my Touareg and whether this is an indication of things to come. Anyone else have similar issues?
