High Pressure Fuel Pump Replacement

High Pressure Fuel Pump Replacement
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?

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?

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.

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.

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!

HPFP getting replaced, MCS R56 51k miles
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".

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!

2 pumps on a turbocharged MCS
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.
