Hey folks, I have 2013 countryman S all4. I'm trying to track down the source of a noise I'm hearing during cold start ups. The sound is similar to what I've heard from a bad water pump.

Basically the noise begins upon start up and then it subsides and disappears completely at the end of the start up sequence as the idle lowers to a normal rpm. I'm wondering if anyone has any experience with something similar.

 

Could be your HPFP. It's a common part that prematurely fails, MINI USA has an extended warranty that will replace it for free. Dealing with certain dealers is hard sometimes.

How many miles are on your CM?

 

I just crossed 50,000 miles. Also the sound emanates from the very front of the engine bay.

 

Does your car have the original Serpentine belt? Pretty hard to diagnose without hearing it up close. Could be lots of things.

 

50k miles is where some of these HPFPs start going. What you explained is a very common symptom of an HPFP starting to go. Best bet is taking it in to get diagnosed.

Mine just had to be replaced in Jan, i was at around 50k miles. My would hesitate at start up, eventually grew to where I would get a power cut from the HPFP not being able to feed the proper fuel.
