BLUF: I would not recommend MLO. Given
@open country first hand experience above, I will defer to others' experience. My review below is as objective as possible.
Cruiser when arrived to MLO: p2420 code and LRA aux tank working as billed.
Cruiser when "completed" by MLO: p2420 code and LRA not functioning the same as when dropped off. Res ipsa loquitur.
My experience in...brief:
I made the drive to MLO, dropped off my car for the next week to give them plenty of time to work on it. "No time crunch at all, please chase down this CEL issue" was my attitude given they would have the truck for an entire week. They had other jobs until the following Wednesday AM when my truck was up. Awesome, let's get to the root of it. MLO completed a round of vapor/smoke/whatever testing without leaks and install "looked really good." They drained the tank of fuel to be able to drop it to look at lines (I'm assuming they checked the lines anyways). The tank had to be dropped to get to charcoal canister. The existing charcoal canister was full of fuel per the MLO guy I talked to. They did replace the old, fuel ridden charcoal canister with a BNIB OEM charcoal canister I left in the back given the persistent p2420 code we were looking to fix and fuel smell/extra weight with the existing one. Great! Job done, right!?! I drive several hours back to MLO, drop off a rental car, uber to MLO for pickup and it's out front as promised. I get my fob from the drop box and take off with a red light on the LRA fuel gauge and no CEL codes. Fantastic! I make the drive home and fill up with fuel once I get home given the empty LRA tank and thimble sized OEM tank. When I got around 40 gallons of fuel split between the regular tank and my LRA, I hung up the nozzle, get back in, and head home. I look down and notice the red LED remained. No green bars. I was spent given the day of driving and was just going to let it go and look to try and fix wiring another time if CEL was truly fixed.
The next morning, I get up to go to work and was greeted with a CEL (P2420) and a single red LED on the LRA readout. I waited to see if the LRA fuel pump would actually get gas from the aux tank to the main before writing an email to MLO. It does function, but only for a few moments as the tank is reading "empty" and I'm guessing they don't want you burning up your pump trying to transfer fuel that isn't there.
I reached out via email at this point and got a reply that didn't inspire confidence. No problem, I understand people have bad days, things happen, etc.
This level of "I'm not sure...." continued for weeks. No accountability or offering to "make it right." Just a "without looking at it again, we don't know what it could be." If the shop was down the road, no problem. I'll bring it back whenever. It is a several hour drive each way from me. Hence, why I gave as much time as I did from the outset. I am being as objective with chain of events as possible as there was a lot of finger pointing between LRA and MLO with respect to communication and the lack thereof.
Which brings us to today - where I have still have a daily P2420 code, a single red LED on the LRA module, and a fuel transfer pump that thinks it's going to burn itself out irrespective of aux tank volume.
Everyone makes mistakes in business. What separates good businesses from the rest is what they do to recover from their mistakes. I hesitated to write this experience as it is overall negative in nature. With that said, I have given ample time for whatever MLO was going to do to "make it right" to occur and their inaction speaks volumes.
I will continue to seek trustworthy shops to try and chase this thing down and remedy whatever is going on. When that happens, I will follow up. I hope this experience is clear and helps others make an informed decision.
Any other shops in central NC you gents recommend would be most appreciative. I saw the prior rec for H&H in Charlotte and the shop in SC. I am hopeful to find a reputable shop that is not hours from me that can figure out whatever is going on, to build positive relationships, etc. TIA.
