hi everyone,
i am new to the forum and i am posting elsewhere as well. I just took my "2011 Mini Countryman S" with 60k miles to the dealer after it started running crappily and i feel like these problems should be pervasive and could help others.


possibly we can even start a recall campaign as the solenoid issue could be a result of poor craftsmanship.


The car was throwing a bunch of error codes on the OBC like
<<
Multiple misfire detected
Cylinder 4 misfire
P0300, p0302 p0304
P0087 fuel rail system pressure too low
>>


All those problems were a result of my high pressure pump faulting. That could be a result of wear and tear. I also found out that previous mini models had issues with the pump faulting and there might have been some recalls as well, but my model has a newer pump. Guess what, that starts to fail now too :(


When the dealer opened the car, they also found that my oil pump solenoid is leaking oil into the wiring harness (the electrical system that plugs all over the engine). Damaging the wiring harness could short the computer and overall moisture and oil on that harness is bad.


I think the latter problem is a result of poor craftsmanship. the dealer wants 600 usd to replace the solenoid, but the wiring harness replacement is twice that amount.


have others gotten similar problems on their minis?


good luck everyone and drive safe.

Two oil pump solenoids have leaked on my car. Both were replaced under warranty, the most recent one just a month ago. Evidently the fix now is to replace the wiring harness with one that is epoxy filled, so that when the solenoid leaks again the oil doesn't make its way to the ECU.

Talk about a half-***ed fix...

 

I hear you. good for you that this was under warranty.

 

I can confirm that the 2011 HPFP is a POS just like all the others. I also have the solenoid leak but I currently can't get any warranty work done due to being overseas. You're still under warranty and they want to charge you for the replacement?

 

thanks u238. I am not under warranty anymore since my car has over 60k miles. :(

 

I haven't done the replacement myself, but it appears to be a seriously easy job if you are at all mechanically inclined. The pump is right at the top of the head. The dealer did it in under one hour for me.

The solenoid is much more involved. You have to drop the oil pan. :(

 

My car was dropped off today to have the HPFP replaced for the second time this year....

 

Had both HPFP and LPFP replaced.

 

That how Mini improved the design of a leaking oil pump solenoid, why don't they fix it to where it doesn't leak? I just don't get it.
