Yes, it was about time to changing my HPFP. I'm not the first, neither the last one. But I feel like an idiot after paying 78.000 Euros for a car that is equipped with such crappy components such as HPFPs, LPFPs, injectors and coils (3 changed). And there is no recall campaign for us living in Europe.

I could understand if it was only my car which is FBO + meth with 400+ whp but is is 9 out of 10 cars with the same problem.

This is what happened to my car today. After a few hours and 500 Euros less everything was fixed.

2 Things:

1. You prob shouldn't have forced the engine to start multiple times when clearly something was broken. Adding insult to injury, you know it's the HPFP and proceeded to force the engine to start, and then rev'd it The HPFP isn't going to magically fix itself, so you certainly aren't doing the engine any favors by repeatedly trying to start it.
2. The HPFP/LPFP is a known issue, Injector Failure is super rare but is recognized as an issue. Ignition Coils are a routine maintenance part that will need to be replaced on a 100% perfectly healthy engine.

Yea, it sucks that BMW hasn't issued a recall on European HPFP's. But like any other performance engine, nothing ever runs smoothly 100% of the time -- This goes for the N54, the S54, the S65, etc etc (and these are just BMW performance engines).


If you wanted an engine that will never break, you should've bought a Honda Civic.

K20 swap for 335? lol

I hadn't heard that ignition coils should be replaced as maintenance. Is there a known recommended interval?

IDK if/what the recommended interval is but coils are a wear and tear maintenance item. They eventually will go out.

[stratos_335]

As said before, BMW is supposed to be a premium and luxury brand and you get what you pay for. I'm a mechanical engineer and I know that when R&D is involved on a part (ie HPFP) then many things can go wrong. But there is no recall for that and I feel BMW people are taking advantage over us paying for a mechanical part that fails all the time.

Ignition coils are not routine maintance parts. Brakes, clutches, tires are maintenance parts but not ignition coils. It's like saying that DME is a maintenance part lol

I just it is ridiculous paying a serious amount of money for this car to have symptoms like dying HPFPs.

As for the Honda comment, sorry but I feel like convincing someone who drags his 335i to sell it and get an EVO (4 wheel drive, less weight, potential of extended engine tuning).

After stopping the video, the system built up enough gas pressure and I made it to the workshop for the replacement.

Lmao at this.

OP, is sounds like your turbo's have a bit of whine as well, unless it was cold?

Ignition coils usually start failing between 30-40k miles. That's why they're usually a cause of misfires. They're not as "routine" as brakes, oil or tires, but require similar attention that spark plugs should get.

My ignition coils just got replaced with spark plugs by the BMW Dealer for the scheduled maintenance, so it's not a "lifetime" part like the fluid in your trans

are you saying the ignition coils are part of the maintenance package? Or you just had them do it when they changed the spark plugs?

I just got my SP replaced in March as part of the maintenance, but nothing about Coils.

Mine were done as part of the package (no charge to me) -- They even replaced the batteries on both of my CA keys

I don't know that I'd say it's rare. I'm on my 3rd SET and have already replaced one to begin the 4th SET(pretty sure I need to replace more, but haven't been able to isolate which ones). This is with only 56k miles.

Still on my original 6 But my HPFP was replaced under the recall

[ZTUNER]

Wonderfull cars. 3 hpfp in 36 k miles, 1 fp sensor, 3 window regulators in driver door. Still randomly has long starts. It sucks when you have more fuel pump changes than oil changes.

[boostaholic786]

Yea it def sucks your having to deal with HPFP issues in Europe when in the U.S., that is a standard recall. Coilpacks depend more on the advisor I think rather than the dealership so make good friends with your advisor and I promise it will pay off. Atleast get you a discount or have BMW split the cost with you. I can understand your frustration but you pick your own poison. I would WAY rather have a 335 any day over an Evo LMAO. Come on man lol your comparing apples to oranges... more like Lions to monkeys haha

[stratos_335]

^^^^ LOL

I didn't know that ignition coils are consumables and need to be replaced. The changing interval is 40-50k miles --> 65-70k km. I changed mine at 5000, 12000 and 17000 and the spark plugs every 10-12k km as soon I get misfires on cold engine start up. No leaky injectors for the time (6/09 production).

You might be able to get the HPFP/LPFP for free in the EU.... just complain and explain your point of view with respect... they are premium and do not like bad marketing....
they will book it on customer satisfaction or something like that.

I've already done that, thanks. I've also sent them a complaint about my rear turbo which burns some oil. You never know...
