I believe the dealer can swap your vehicle "country code" in the BCM to change that

I have no idea how many vehicles cross the border when sold.

 

Maybe your issue is just that your dealer in TN has no clue. Maybe do a little googling for a major dealership near the border in NY or Mich or something and call them for help. Just a thought.

I'd avoid dealerships altogether, unless you need a system still under warranty repaired. You'll save yourself a TON of headaches.

 

You might have to branch out of your local area to find a shop willing to tackle this one, but most small independent garages will have the capability to fix this one. Whether they want to take it on or not is a different story. Has the potential to be a long, drawn out deal, which most shops want to avoid.

No way in hell any dealer will do that. You'll have to find an independent garage.

 

Like I said, finding someone willing to do it is another story. If it doesn't go well, they have to eat a new BCM. I know one thing, no way I'd want that on my shoulders.

 

You're probably going to have to scour the internet, and make some phone calls to mobile programmers around the country, and pick their brains. If it's possible, or not, they'll tell you. There's a ton of guys these days now that do nothing but programming work. Some guys have no fear, while others (rightfully) won't dare risk losing money.

Had it done at the dealership to my BMW ? Wasn't a big deal, just found out how it was done and brought the instructions with me.

 

Another example of dealership being pretty cool, I just installed a 2" lift on my truck all the way around '17 Denali. They re calibrated my ride hight sensors for the magneride for free since they didn't know it was possible until I explained it all to them and showed the tech. Not a common procedure but built into the software.

 

Don't be discouraged, it will definitely not be a "common" procedure in a US dealership, so it may take some positive thinking and a little bit of research but I think it's doable !

Like I said ... the hell with the dealership!

 

Trust me - you'll save yourself ALOT of headaches just finding a competent independent programmer.

      OCI, not when but why?

      By Chuck FB · Posted

      If all oil manufacturers had to meet a higher standard for not just the initial filtering of the oil but that they had to improve on their formulation so that the oil cleaned the engine such as the Valvoline R&P or the new Mobil product ( assuming it works similar of course ), and the oil was changed on an interval based on good UOA data, there shouldn't be any gremlins running around like miniture rats on top of your heads to be washed down into the oil pan below 😁

      OCI, not when but why?

      A while back on another thread there were comments and thoughts on air filters and I know that can tend to be a bit of a hot topic because of outfits that have a vested interest in selling aftermarket air boxes fitted with the gauze type of oiled elements touting the lower air restriction. However and unfortunately I don't know where I have seen the test results in the past about the amount of dirt through a test procedure that these style of filters do pass more dirt through than a properly designed ( not some cheap Chinese knock off ) paper/synesthetic media filter can do. Lake Speed had a conversation on that topic with one of the employees at Donaldson and there seemed to be a consensus of these oiled filters falling short in the absolute percentage of dirt holdback.    Which all ties back into how good the air filter is on the engine at keeping dirt out as that is going to reflect as a contaminant introduced into the oil as well as cylinder wear even if some of that dirt does find its way out of the exhaust rather then the crank case. Put another way that one can throw the kitchen sink at filtering the oil and using a bypass system which I fully expect will do nothing but good for the oils contamination but if the air filter system isn't doing its job then its preventing the engine from reaching the best wear/lasting case scenario instead.    Now perhaps this topic is or isn't for this particular thread but Grumpy Bear or anyone else for that matter, do you have access to some scientific trust worthy testing on engine air filter types to get some proper comparison data to post up.

      WOW, something we agreed on. I only bought at sticker twice. A 94 impala ss and an Acura intagra type r. Made money on the first. Still have the second.

      I prefer new, but not without a deal. Historically I've bought severely aged new inventory, leftover model year, unpopular configuration kind of stuff that sits around on dealer lots until they just want it gone. $10k off MSRP kind of stuff on a mid-priced truck. That really, really helps knock down that first year depreciation. It also requires being somewhat flexible on colors and options. I wouldn't buy a 4 cylinder if I was looking for an 8 cylinder, but if I got blue paint instead of black, or a great deal was lacking a minor option, I'm willing to overlook those things for savings.   Used <> used. Condition and history are everything. If I'm buying used I'm looking for cream of the crop. The truck from the guy who religiously pampers it, and then decides a year later he wants newer and nicer. NOT the ex-rental vehicle, or the crew cab traded in by the family with 7 kids who like to throw food, and the oil only got changed when there was time long after the oil life monitor started alerting.
