I have a 2001 bmw 325i with 100K miles. Just had the a/c and heater replaced for $500.00.
Now I am getting notices to service my car. The test that was done showed something about the camshaft and others about the 02 sensor? Another PO300 had to do with the sparkplugs/and missfire? The test also revealed P13345, P13343, P13347, PO171 and PO174.
My car has not been starting in the heat. Then when it starts it goes to a crawl of 20 mph. Then the next day it will be fine.
Can anyone shed any light on this for me? I trust my mechanic. But he has been away on vacation. The mechanic I saw did the test that showed about 6 numbers. Could it be that it needs cooling agent or something minor? I understand the sensors are an issue. You have to fix them as you go along or can one sensor that is off, make the others off also?
Thank you for a advice! Pat @ firstname.lastname@example.org
