TL;DR, "BMW trained technician" damages aluminum head, charges customer for parts and labor to fix the damage he caused. Vehicle in shop for nearly 2 months, $7456.39 in repairs. Vehicle is headed back to the shop soon because their shoddy work failed (today) about 2 months later.I've avoided writing this review because I was waiting/hoping to hear something/anything from BMW. I filled out the post repair survey around 2 months ago and haven't heard back yet, so I guess it's time to write some reviews.This whole ordeal began in May 2018 when I took me vehicle (2010 X5d) in to have a broken exhaust manifold stud replaced. I diagnosed the vehicle myself and took it in to confirm my diagnosis and have the repair done. I could have done this repair myself; and in hindsight wish I had, but I don't have an air conditioned garage and I wasn't keen on doing this repair under a carport in the summer heat. So I took it to the "professionals" and the "experts" confirmed my diagnosis.After running the codes they also suggested I replace the DPF (diesel particulate filter) and the active DEF (diesel exhaust fluid) tank. I knew it was going to be an expensive repair bill, but this is basically the first time I've ever had to spend money on the vehicle, other than routine maintenance, in over 100k miles. So I told them to go for it.The initial repair job took a little over 1 month: replace exhaust manifold studs, gaskets and related parts. Replace DPF, active DEF tank and related parts.Once completed the vehicle was trailered to my home about 1 hour Northwest of Wichita Falls. My wife takes it out for its first drive and not 5 mins later the CEL (check engine light) comes on. Call the dealership, they come pick it up and trailer it back to Wichita Falls. Around 20 days later the vehicle is fixed/ready and it is delivered to me at work on Altus AFB.And now, about 2 months later, something is seriously wrong with the vehicle again, and it is absolutely, without a doubt, related to the previous repairs.So as you can see there are many reason why I would give BMW of Wichita Falls a 1 star rating, but the #1 reason is the fact that I was charged for parts and labor to fix a "BMW trained technicians" mistake.How do I know this you might ask? Two reasons:#1.The Heli Coil and associated labor I was charged for on the invoice to fix the damaged threads in the aluminum head.#2. The physical evidence on the extracted exhaust manifold stud.I always keep the old parts whenever I get work done on my vehicles. And one look at the extracted exhaust manifold stud told me and any other mechanic I've shown it to exactly what happened.The physical evidence clearly shows that the stud was incorrectly drilled at an angle (not straight), thus causing damage to the aluminum head, necessitating the use of a Heli Coil to repair the damage.I asked the service manager if it was a common practice to pass the cost of repairing their technicians mistakes on to their customers. Because in my experience (I used to be a mechanic), when I broke something while working on a customers car, it came out of my paycheck, it was NOT added to their invoice!The service managers excuses, justifications and explanations were infuriating to say the least.And now here we are. The vehicle is heading back to the BMW trained technicians in Wichita Falls soon. How long they'll have it this time? Will they break something else and then charge me to fix it? Only time will tell.
