[2008 BM 535XI] So Ive got this code before, and I cleaned out my vans solenoids and the code disappeared. The car then ran fine for a couple months. Recently my water pump gave out so I replaced that and now when I try and drive it, around 3000rpm in 2nd or 3rd gear (automatic) the car give the code again. I tried cleaning the solenoids again but no luck. I tried reading the codes with an OBD scanner but the codes are all BMW specific. Does anybody have an idea on what else it could be? Or do i just have to bring it to someone who can read the codes for me?

CODES:
P22AA
B2AAA
P22AA
B2AAA
B2A00
P0000
P0000
P0000
P0000

 

How many miles on the car, and did you swap out all the Mechatronics seals, tubes, etc?

 

About 170,000km on the car, nothing has be replaced except the starter, water pump, thermostat, voltage regulator, and the stock airbox (swapped it out for a cold intake).

 

How old are your spark plugs?

 

You need to buy a BMW DTC code reader; they are not expensive at all.
