Failed smog POX - 2009 BMW X5

when you disconnected the battery you cleared all codes and your emissions[ smog/emissions need to run their cycles to be smog test ready as of now you will fail test ------https://smogcheckvacaville.com/general-motors-drive-cycle-for-smog-check/ ------------------https://repairpal.com/how-to-perform-a-basic-drive-cycle

The smog check requires a visual inspection of your check engine light. It has to come on for a bulb check at startup to make sure it's working. But, the light must go out after starting the engine(it cannot stay on after the engine starts during a smog check). If the check engine light fails either of these two tests, the vehicle will fail the smog check inspection.
You need to have the cause of your inoperative check engine light diagnosed and repaired.

Because you failed to have a shop look at the data
& make the required repairs & get caught up on preventative
maintenance BEFORE you went to inspection

If you were in fact at a shop, for any reason,then they have no idea
how to test vehicle

Have you considered the motor is shot & you have leaking valves?

code p 1340 refers to crank position sensor and camshaft position sensor signals out of sequence
the results of the pretest smog test at 2400 rpm suggest that the cam advance solenoid or system is failing
that will alter the sequence of the signals resulting in the code and failing of the smog test
as to answer you question , I am not convinced at this point but I consider the cam advance system to be at fault and would be testing in that area

means that the hc,co2,nox, emissions are too high, you will need the numbers in ppm on the read out to begin diagnossis

No the water pump will not affect the smog test. You probably failed the idle?
Usually with this age of vehicle you can replace the o2 (oxygen) sensor and it will pass. Cleaning the MAF if it has one cant hurt either if you do it right.

replace the pvc valve and have the egr valve replace.make sure the vacuum hoses connect to egr valve and pvc replace.change air filter.all those things will cause high emission if not working properly.cause you to fail smog test.

We had to have the calatic converter replaced. We did this after doing an oil change, air filter change, and new spark plugs and still hadn't passed smog. After changing the calatic converter it passed smog with scores of 25.

looks like you need to replace the co2 sensor
