Water pump replacement... clearing codes required?
I have an ’08 135i and it seems my water pump has died. If I don’t clear the ‘shadow codes’ will the cooling fan keep blasting on high even after I replace the pump? Or will it go back to normal once the ECU sees that the pump is operational again?
Is there a way to bench test the pump to verify it’s really dead? I’m not sure I can just jump 12v to it since it’s controlled by the ECU. When I do the coolant bleed procedure in the car I don’t hear it running, but I’m not sure if it’s that loud even when working. |

This is for an e90, but the same process for the 1 series. Easy to see if the pump is working correctly...
key in, foot off of the brake, hit the start button. Foot on the gas for 10-15 seconds will activate the electric water pump. |

Mine all went back to normal after WP replacement and bleeding. No codes or high fan...

I’m about to change mine, still functions okay, but I have 114k miles and I’m servicing my turbos soon and I have no idea if its original or #2. Though it has made a few buzzing noises at times.
I was wondering if it needed coding after installation? Because the new VDO pump says on the box “needs programming/updating when indicated. Observe the guidelines of the vehicle manufacturer.” |
