i guess you are tuned considering the 2D18 code? you need to add ALL INFO about the car. not only codes. Also try to search them here , you will find tons of threads with troubleshooting help.

Yes, you need to replace the low-pressure sensor. The 2A99 is not being caused by the crank sensor. Probably related to the vanos on the exhaust cam. Possibly a vanos solenoid issue.

Yep. Vanos solenoid to start, might as well do both along with the low pressure sensor. Then if the vanos solenoid doesn't fix it, you probably have a worn exhaust cam bearing ledge. You'll have to pull the valve cover and front cam bearing cap to check for wear if that's the case.
