Thanks for the great comment, we hope to work with you again too!Kevin Brown
Dropped my truck off at Garrett’s at 9-am picked up at 1:00pm same day! How awesome! Thanks , Bob
It is always unfortunate when repairs do not go as hoped. You brought in your vehicle for having low power and because it would not complete a regen. We provided an estimate for repairs, which you agreed to. After the repairs were completed we advised there were parts quoted to you that we did not need to replace, so we did not charge you for them, then advised there were more codes in the truck which we would spend some time to figure out what the next best step was. Below is the write-up, copied directly from the invoice
"After sending DPF out for cleaning, reassembled. Reset DPF, cleared codes, warmed up truck, and drove. After 20 minutes DPF message on dash and Code P1451 DPF system performance. Only code that set. PCM had to relearn the new soot load in real time. Initiated a stationary desoot, After 80 minutes truck completed the process. Drove again on freeway above 55 mph so the system could get an accurate reading of the filter. DPF soot load now reading at 2.00 g/l on freeway, No check engine light came on, and code P1451 went inactive/stored. And operating mode returned to normal. 2 new codes set that are pending. P0401 for EGR system performance. And code P0299 for turbo charger under boost. The truck is on E. With a fuel range of 10 miles.
Next added 10 gallons of fuel, drove again to complete 2nd drive cycle. After 30 minutes of driving, exhaust message again came up on cluster for exhaust system full. The estimated soot load is up to 7 g/l. Additional codes set. P2463 DPF SOOT ACCUMULATION, P242F DPF filter restriction, ash accumulation. P2453 DPF pressure sensor A circuit performance. As well as the P0401 EGR system performance and P0299 turbo under boost condition. Checked 5 volt and return signal at the exhaust differential pressure sensor, ok. The DPF was just cleaned, and a stationary regeneration completed. The sensor was reading normal but looks to have a skewed reading of what actual reading is. The exhaust temperature sensors are all reading. Continuing with checking the truck out, I found the air filter is restricted. The turbo fins on the inlet are intact and it does spin freely. I attempted to perform the air intake pressure test. With current test equipment was only able to get to 10 psi of pressure, test recommended 20. Sprayed connections and did not see any bubbles. I removed the exhaust pressure sensor. The sensor is clear and so is the pipe to the sensor. I removed the EGR cross over tube and temp sensor and it was not restricted. I removed the intake manifold temp sensor and found it covered in carbon/soot. I put a camera through the sensor port and can see lots of carbon/soot build up in the intake.
Next course of action is to take the truck to the dealer, at this point our software capabilities are limited and the dealer will be better equipped to ensure proper repairs."
