Thank you for the replies.

Please forgive me if this has been addressed, I reviewed the forums and didn't quite see my question. I upgraded the halogen projectors in my 2015 to an HID kit. This has solved my night time visibility issue I had with the halogen, however, the issue is the new HID lights stay on all the time at full brightness due to the DRL function. SEL models, like mine, use the low beam lights at a reduced wattage as the DRL system. Titanium model's with the factory HID's use the high beams as the DRL. Here's my question, how do I go about changing the programming to either 1. turn off the DRL completely and have no lights on during the daytime, or 2. change the programming to that of the Titanium and utilize the high beams as DRL. My dealer said the Edge has non-configurable DRL, meaning I have no option to go in the lighting settings in the menu to simply turn off the DRL. The dealer said that it is possible (after much debate) to hook the car up to a computer to disable the DRL but they refused. Any suggestions?

Since yours is a 2012 it'll most likely be a suck and fill procedure. 2015 and newer have a drain plug that makes PTU fluid changes easier. I'd use a pump and suck out as much as you can from the PTU and then fill with a high quality 75w-140 fluid like Redline. I fill mine until it drips out of the fill plug. I ordered my Redline fluid from wally world's website for less than 20 bucks free shipping. MACT did an excellent write up on youtube and showed that Redline has excellent additives. It's a shame that many, if not most, gear oils are severely lacking a robust additive pack. I change out my PTU fluid every 8k miles. Certainly many would think that's overkill, but I'm in Texas and the heat roasted one of the PTU seals at 47k miles. On my new seal and doing PTU fluid changes religiously now, especially since my powertrain warranty is up. Hope this helps.
