I'm Back. New X5 35d

[Meinhold]

Well, it's been just a little over 3 years since I sold my 05 e53 4.4. I bought a 2016 Range Rover L405 TD6. Before you say anything, I love this thing It's been very reliable and it munches the miles.
However, I'm trying to not put too many miles on it and I came across this 2011 X5 35d It's in great shape the interior looks new, and the body and paint are 8 out of ten. 142,000 miles on the clock. I got it for $3800. So of course there is an issue and I'm sure you all can guess. Yup, it's the DPF. I don't think anyone has tried the Liqui Moly two-part cleaning. So I'm going to try that first.
Also, has anyone just drilled a 3" hole in the DPF and had it work?

My plan for the X5:
I have a goal to ski 30 days this winter and live on the central coast of California, any good place is 400 miles away. So I'm going to put the miles down this winter. I want to find some 18" wheels and put some Toyo open Country III that are Triple Peak. Might even do a spacer lift so I can put a little taller tire on it.
So other than doing a complete service. I should be off to the races. I just need to deal with the DPF.
Any suggestion will be much appreciated.
