Soooooo car still is hesitating on acceleration.

Work that has been done:

Carbon Clean (today)
New Bosche plugs & coils (Sept 10th)
Oil change & filter (sept 10th)
Turbos and Value cover checked out ok (today)
Air filter (today)

Shop said it maybe fuel injectors ($$$$) but I'm not tripping any codes. I have an AP2 tune, was happening before tune. My FMIC and charge pipe seem secure, don't think it's a boost leak.

I'm tired of tossing money at it only to check that off the list and have it be something else.

Suggestions before I go insane and broke?!?

I would say do a few pulls and log and try posting them. I would bet injectors as you seem to have ruled out everything else...unless you have a waste gate sticking open or something...

This happened to me! It was the injectors. Swapped them and problem solved! I accidentally turned my jb4 off while running my e85 mix. Messed them up

[Down_Shift]

injectors don't trip codes early on, they will start to getting misfires and lean/rich codes when the weather gets colder, especially on cold start.

Try injectors. Especially with the temps dropping they are more likely to have issues. I can post up the info to buy them (OEM source) the cheapest.

Please do. I was told "around" $2,600...?

This issue has been happening since summer

They can be found at Rock Auto. The OE for BMW is Intermotor. They even have the BMW logo on them. I think I purchased all 6 + OEM Injector rings for under $700 IIRC.

Gotta love the price they charge for coding. I had zero experience coding BMW and got everything set up and coded injectors on my last 335 in less than an hour.

I'm a little shocked at the price of injectors right now though. I ordered 6 last August and paid 900 through getbmwparts.com. Right now, they want 1,330 for the same exact order. Crazy!

** Just checked Rock Auto as others are reporting, ended up placing an order for 6 injectors for 697.42...wow.

BMW dealer ran it and said my low pressure fuel pump sensor went...

Does this sound right?

They want $700 which is ridiculous, but I'm thinking of doing It cuz I can hold them accountable at least if it doesn't solve the problem

What a rip off. Buy a fuelit for 1/2 the cost: http://www.fuel-it.biz/n54-135i-e8x-...grade-options/

I would do a log and look at your LPFP...

It's just the sensor, I can get it for $82!!! I just want to hold them accountable if It doesn't work. I think DIY or outside shop, I don't have a chance of getting injectors out of them if it turns out not to solve the problem. During the recall, they only replaced 3 of the 6 so I'm willing to bet the issue runs deeper

That is typical (only replacing 3 out of 6) They don't fix what isn't broken

[Sean978]

Its going to be tough to hold them accountable if the fix they recommended doesn't "fix" the issue you're having. If they do the labor then you might have a case.. But I doubt they will ever take responsibility for a repair not resolving an issue.

Yeah they wouldn't... At least I got the diagnostic done for free. I called Turner picked up the sensor for $82 and intake manifold gaskets for like $30 🙌🏻. No way I'm paying that esp if they're not going to guarantee it, on the way to my buddy's tonight to do the work, fingers crossed
