P1212 is an ABS issue so won't cause it not to go, U1000 is caused by a poor or loose Ground connection. This could be almost anywhere on the car but start in the engine bay and wok from there, removing and cleaning ground points and re-tightening.

I am having the same issue on my 2002 Q45, most people that have had this problem have replaced the Starter Solenoid - You dont need to replace the whole starter, unless you have alot of miles. I ordered the part and I am going to try and install it this weekend. Almost everyone with this problem said that after replacing the solenoid the problem went away. Either do it yourself or have an independent mechanic do this, the dealer wants $900 for replacing the starter parts and labor. Solenoid is about 92 bucks online OEM.

hood lever inside first, then pull up on the hood, it should only come up about 2 inches, then the lever should be dead center kind of behind and below the grille.
