Looking for a shop, or even someone knowledgeable and willing, to delete and tune my 2009 bmw 335d. I’ve had it for a few months, and have barely had it on the road in that time frame. First off, it needed a new egr cooler. I got that replaced, and drove it for about a week. Now it says the def fluid is wrong, and it will shutoff and not start back after 150 miles. Mainly wanting it on the road reliably. But wouldn’t mind the added performance and mpgs either. Any help would be greatly appreciated. Thanks in advance.
