Well, add my name to those who have had to have their high pressure fuel pumps replaced. We were about an hour out of Houston en route to Austin when the the engine abruptly stopped running.....no warning....no sputter....no nothing....just stopped. We were at highway speed. As soon as I figured out what was going on, I headed for the shoulder. It wouldn't restart, so I called MINIUSA. We were towed back to Houston where they diagnosed it as a dead fuel pump. We only have about 24,000 on the clock.

I've been half way following the high pressure fuel pump problem on the carbon deposit threads (my previous problem). It sounds like this is a fairly common problem. My question is this.....Have any of you who have had this surgery done on your MCSs had to have it done a 2nd or 3rd time? My reason for asking is that I'm wondering if they're replacing the original pump with the same, flawed equipment which will probably go out again. Or, have they sorted out the problem & corrected it?

HHH

 

i also just had mine replaced @53,000 MINI USA was nice enough to replace it under Warranty even after the Warranty was up

 

Hopefully this isn't a common problem. I just bought an 07 MCS on Wednesday. Thursday morning I get ready to head to work, and it didn't start. The dealer I bought it from had Mini Peabody come get it and fix it. Turns out the high pressure fuel pump had died. Is this something I should stay on the look out for?

 

My HPFP died last December, about 24k miles. I say it's one to a customer but it's definitely a part that goes out based on what I've seen on this forum.

 

Actually, it seems like there's a lot less talk about the fuel pump failing than the cold start rattle. Either way, I think you have to treat any statistical conclusions drawn from the number of posts made here with a high degree of skepticism.

 

Count me in that one
at less than 3k miles they yanked mine out
The light then came back on and they think it was a ghost they said drive it till the light comes on a 3rd time

 

Mine died en route from Houston to Austin about 2 or 3 weeks ago. They towed it back to Houston. The 1st diagnosis was the fuel pump had died. Then they said the fuel pump was O.K. & somehow the siphon in the tank was malfunctioning & not sucking up fuel. Interesting....I wonder if that could be a contributing factor in some of the fuel pump failures. The fuel pump gets starved.....The fuel pump over heats.....etc. I think they said they replaced the siphon & fuel filter. Anyhow, all's well & we drove away.

HHH

 

I just had my high pressure fuel pump replaced under warranty at 28K miles. I hope the one they put in was better than the one that came out. It had started to sputter our at part throttle acceleration, and then would not stay running on start up when cold (sitting overnight)

 

count me in also..was driving and the engine stopped. 15500 miles 08 mcs

 

I've posted elsewhere but mine died at 700 miles.

 

...just picked up mine from the dealership with the same issue. About three weeks ago the car had a hard time turning over but once going it was fine. Just this past Monday the engine light came on had to take it to the dealer and viola' new high pressure fuel pump.

 

Count me in on this one as well. Like Acender, I was "fortunate" enough to have the cold-start (sitting overnight) problem. Just had the hpfp replaced last week. All's well for now, 30K on the '07 MCS odo. Here's hoping it is truly "one to a customer"

 

Mine died in my 07 MCS before I traded it in. I think it was at about 20k. It wouldn't start when cold outside and normally took several tries to get it going.

 

The HPFP in my '09 MCCS died at 340 miles...

 

Has anyone had this done outside of warranty? I just had my timing chain/tensioner/guide rail/etc replaced, which MINI replaced under warranty due to all my previous complaints to the dealer about it. The very next start (the next morning, since it was running when I picked it up) was a stalled start that worsened to an engine light over about six days. Quote for parts only is $1072?! I know DFI is high pressure, so I was expecting more than a "normal" fuel pump, but daaaaang.

 

Seems like more of the newer cars are having this problem... (knock on wood ) ....

 

I wonder if its the same part that just had on with the 1-series. It just got an extended warranty out to 10 years.

Interesting! It does look like there's new version too, as of 04/08. Well, at this point I believe I've hit every major common mechanical fault, so here's to driving on without any more issues!

 

Well, mine died at 700 miles and its a 6/09 build... from what I understand after further review, the HPFP is bad on a lot of recent turbocharged BMWs.

 

Our 2007 MCS R56 is having it's timing chain tensioner and high pressure fuel pump replaced as we speak. 1000 miles out of warranty. Mini and the dealership are covering them both. Though they would only do it if we paid then to cover break fluid replacement and cabin filter replacement. The car had to be "up to date on it's service". I suppose that's fair, though the cabin filter replacement is "dumb".

 

Turned out to be the timing chain tensioner, and the Vanoss solenoid. That was in November. They replaced the HP fuel pump, and it didn't fix the problem the first time. It's Feb 2010 now, and the R56 is back in the shop. They tell us it's the HP fuel pump, and will cost $1200 to replace. We were told they replaced it under good will the first time. Don't know how this will play out. Will update our post again with the answer.

Ug...

 

I am curious. What style pump is it? I remember back in 1983 the Subaru GL wagon would go through fuel pumps if you ran it low on gas all the time. It was a recirculating type which relied on the gas tank being roughly 1/4 full...

I dunno if the HPFP is the one cooled by the gas or whatever, but being in TX where things can get hot, I've gotten in the habit of refilling when I get around 3 bars.

 

Don't stand for this. Not for one second. The HPFPs are a known piece o' crap, and all you need to do to make that case is print out page after page of posts about them failing from here and any other Mini board with any traffic. For good measure, you could do the same from BMW boards, as the HPFPs fail just as frequently (if not more so) on the twin turbo N54 motor that's been around since '07.. and the problem still persists.

When and how many miles ago did they replace the HPFP the first time? Because there should be some sort of warranty on the new pump, even if they "paid" for its replacement.

Good luck, keep us posted. Don't cave in!

 

The R56 turbocharged MCS has two pumps. One in the tank, and one in the engine bay. The one in question is the High Pressure pump in the engine bay. This feeds fuel from the fuel line to the fuel rail at a higher pressure than a normally aspirated engine. This is the ~$1200 pump.

The one in the gas tank works like most other in tank pumps in that it's cooled by the gas in the tank (i believe). In the R53 and R56 Mini Coopers, there are two access ports under the rear bench seat. One for fuel pump access, and the other for fuel filter access. The fuel filter is a canister type. Mini specs claim this to be a lifetime filter. Most owners don't agree. Have you seen our gas? When this gets partially clogged, it can cause the in tank filter to burn out. This is not a common issue, but it does happen. IF you believe your Mini has gas problems (sorry), check the fuel pump fuse, then filter, then in tank pump. Testing fuel pressure is "easy" also, and the gauges are pretty cheap. Though, the Mini dealership techs don't seem to know how to do this.
