Pump works.

Muy bueno

I felt compelled to write this review to help balance out the rating for this item and set expectations straight for people on the fence about ordering this EXTREMELY bargain priced pump. I installed this HPFP in my 2008 BMW 535xi E60 in early September 2022 and as of late November (almost 3 months later) I have been pleasantly surprised with the performance in temperatures ranging from -5C to 25C. My car is not a spring chicken with almost 220,000km and I’ve ran a JB4 tuning device on it since I bought it in 2018 with 125,000km. The car is used in stock tune 99% of the time for getting groceries and visiting family that are 300-500km away from home. And on that 1 sunny Sunday every month I’ll put her onto map1 (1bar/14.5psi) and enjoy the beautiful twisty country road I live on.The car was having slight misfire and hesitation mainly going up hills for the last year or so and finally the pump gave up and would throw codes (see pictures) and misfire like crazy on even the slightest throttle increase or inclines on the highway.I was able to do the full removal and install in just 3 hours on my uncovered driveway. I only removed the factory airbox and carefully pushed some electrical/vacuum lines aside. It did involve a lot of painful and awkward hand/arm placement, but well worth the trouble to not have to open the can of worms that is removing the intake manifold and the million things attached to it. A hilarious variety of socket extension and pivots had to be used to achieve this. I did not use the included copper washers on the fuel line connections since the original pump did not use them, and I used the spindle flange O-ring from the old pump since it looked thicker and still in good condition.After installing the pump I did get misfires (not bad enough to throw codes) for the first few drives but then things magically went back to “normal” after about 100km and the original recurring codes 29DC/29F2 for pump/injectors finally cleared and haven’t come back. I assume the initial drama was likely air working its way through the fuel lines from my crude DIY install.I say back to “normal” because I want all N54 owners reading this to be honest about the situation. An N54 has not been produced since 2016 now and the vast majority of us have a 2010 or earlier. These aren’t and never again will be “new cars”, so if you are living in that illusion I highly suggest cutting your loses and picking up a brand new BMW on lease to actually enjoy headache free. For the rest of us living in used and out-of-warranty BMW reality, congratulations! You own an enthusiast car that has lots of “personality” and needs a good deal of attention and routine maintenance. I’m sure most people reading this have the same nuisance codes I do for things like worn catalytic converters, spark plug coils, fuel injectors, VANOS solenoids, throttle angle sensor, etc. So, to me it’s not reasonable to throw up my arms and complain that this cheap pump didn’t cure all the problems my 15 year old car has. I’m just thankful that I’m at a state of “normal” where most of those things only happen on cold starts and the only code I get on occasion is for my cats (that probably need replacing).People who have left reviews about poor quality, I ask you to be realistic about a Chinese made HPFP that got to my door for less than $300CAD. My “top quality” pump came with dings all over the spindle mounting flange that I had to take a file to for a flush mount to the engine block (see pictures). A brand new pump costs $1500 and $1000+ for a rebuilt one, and that’s if you can find one. From what I can find the original Bosch or otherwise German manufactured pumps are long discontinued and hard to come by. Reviewers claiming to be mechanics and automotive professionals, no reputable licensed mechanic is going to install this in a customer’s vehicle, please stop this practice if you are doing this or stop claiming to be a licensed professional. People complaining about bad seller customer service, be realistic, have hope in Amazon PRIME return policy and don’t waste your time and energy on trying to reach out to a company on the other side of the planet who is pumping out cheap product and has no motivation to care about your customer experience. And for all the rest of the salty folks who just had bad luck and received a defective pump, I feel for you, that’s why we should all make sure we install items promptly so we can road test as thoroughly as possible before the end of the return window when dealing with these cheap products.I’m giving this a full 5 stars based on the crazy bargain that it is and the fact that it’s a miracle such a product can even exist and function at this price with a prime return policy. If I get 2 years and 50,000km out of this one I will consider it a win. Especially considering the fact that a German made pump is only expected to last 100,000km if you are lucky. If the pump prematurely goes boom next year, I will be a bit annoyed and update my review to a 3 or 4 star based on the circumstances.In conclusion this is not a trusted premium item to be used by professionals or in any type of high stress “racing” application. If you want a “professional” or “race” grade HPFP then dig deeper and spend the $1000+. This pump is for all of us DIY enthusiasts that are willing to spend the time on this hail Mary toss up, to hopefully save some money and keep our daily drivers chugging along for another couple years.If this sounds like you, I encourage you to make sure you have a PRIME membership and order the pump before these are discontinued or priced too high for what they are. It looks like you have the standard 30+ day prime return policy if you get a dud, it will only cost you 6 hours of your Saturday and the respect of your significant other while you curse about your bad luck in the driveway.Goodluck!

I bought it back in July and it worked just fine until today (about 4 months after and approx. 15K miles). I tried to contact the manufacture trough their website contact to understand what were the part warranty conditions and got 0 feedback, this product isn't reliable, waisted my time and money.

Produces only 140psi when it should produce minimum 1500-2700
