Maxxforce constantly asking for Parked Regen

Last week I purchased a 2012 Prostar Day Cab with the Maxxforce 13 and 162,000 miles. It drove Bobtail the 100 miles from the IH dealership without issue. Now it is constantly asking for a Parked Regen, after the Parked Regen it will run for another 30 - 45 minutes and then asked for a Parked Regen again. I called the dealership and talked to the Service Director and he told me that this issue is usually caused by an Exhaust Leak or Intake Leak. Does this sound like a good place to start looking, or any other suggestions?

 

I have 5 other Pro Star Day Cabs and they have been pretty good. I have one Pro Star Sleeper truck and had a Regen Issue with it, but it was solved with a replacement Fuel Pump and ECM.
And this truck had Low Miles because it was used by United Rental to pull a Drop Deck trailer to deliver Heavy Equipment locally around Miami. It was leased to them and maintained by the dealership since New. I have purchased a few of United Rental Pro Star trucks and have had good luck with them. I paid $18K for the truck with 162,000 miles, Headache Rack & Wet Line. The last one that I purchased 6 months ago had 126,000 Miles on it. I have put another 60,000 miles on it in 6 months and No Issues. I get a Full report on them and the dealer is good to me. My trucks pull Milk Tankers and the furthest my trucks get away from home is 116 miles and they drop & hook, so no long idle times which my research says is their weakness. So to answer an earlier question... Yes, I have done my Research and continue to learn every day. There are some applications where these trucks will work. And a nearly new truck for $18 grand makes it worth the headaches once you learn them. And if you have a helpful suggestion or diagnosis, I would be glad to hear it. If you have a Stupid Smart ### Comment, move on.
