My 135i started crapping out on me while driving today

mechy · 03-12-2010, 01:26 PM

Here's an update. My car threw an SES light a couple of times. Brought it to the dealer. SA said most likely it's the pump. Turns out BMW wants to reflash it with a brand new software not released yet. Should be a couple of days for it to arrive. I think they're pointing towards a software issue now...

My135 · 03-12-2010, 02:02 PM

It sounds fishy to me that a software reflash will fix all prescribed problems. I think the new software will lowered the hp/tq output such that those problems won't occure. So, this is a patch instead of a real fix.

Ask your SA which version they are loading on it.

Just reading this thread gets me pissed off at BMW's service....

It seems like I'm not the only one with new software coming....

Are you just saying that?

Update #2: I spoke to the service manager while retrieving the loaner. He stated that the software update was NOT the full fix. They needed to update the software because every year about this time BMW updates it, so in order to diagnose the car consistently, they need the updated software in the car. So, it still could be hardware related (i.e. pump, coils, injectors, flux capacitor, etc.).

Thank for the update Mechy. Geez, this board is amazing. So much great information, and activity among the members. You guys are awesome.

Update #3: I've been told that the new software was installed today. They had to replace (per BMW) the emission control unit which might've sent erratic signals which caused the stuttering and engine light to go on. Mind you, I've had the long starts and sudden stuttering prior to this, but NO mention of replacing the HPFP. They'll start it cold tomorrow and will take data before releasing it to me. It's been in the shop since for 5 days now...

I've been wondering why the car would behave as normal whenever I re-started the car after having the stuttering. Would the HPFP "resent" itself when restarted? If it was indeed a mechanical failure, wouldn't it misbehave all the time?? This would lead me to believe that it may have to do with software/electronics, rather than mechanical, problems.

spellbmw · 03-16-2010, 07:33 PM

My 2010 135i at 5558 miles went into limp mode this afternoon, just sorta 'bang'. Normal driving and as I started to accelerate, something 'went' -- could just feel the power-loss and the "Engine Malfunction - Decreased Power" light/warning came on, saying it was OK to drive but to get to a dealer for service (iDrive read out). Used BMW Assist to give dealer a heads-up (Kuni in Beaverton, OR) and dropped it off. My SA said they'd have it a day or possible two, depending on what they find in the codes and testing. Gave me a 328xi loaner with AT. Will keep you posted on what they report.

On BOTH of my last HPFP failures, the SES light came on for a day or two, and then acted totally normal. After a couple days though, the SESlight and long cranks returned. This was on both the original pump and the 8XX one. So far the 943 is good. It's only been about a month though.

Update #4: Alright, this is getting frustrating now. My SA took the car overnight to put some miles on it and had the SES and Engine Malfunction light go on two separate times (one in the next morning), so obviously whatever they did didn't fix it. So, they're going to replace the HPFP and are waiting for approval from BMW. Why can't they get this fix right???

Any 943 pumps failing out there?

My dealership replaced the HPFP with the latest version, having tried the software update first which, acc. to my SA, attempts a remap to deal with potential fuel issues and has been reported successful with some vehicles. The new pump is clearly present when opening the door: there is an electronic whirl sound in the car from the rear to the front - something I heard with the older version when I first got the car, but less in recent months (now questioning my own memory, of course). Anyway, performance is smooth and power is back to its awesome, delightful self. I hope this one works. FWIW: my SA said he had had similar issues with his 335i and the HPFP. Excellent service at Kuni BMW!

None from any 1Addicts posters. Keep your fingers crossed!

Odd that both of our 2010s didn't have a single issue until today. I had my first long crank today at 4k miles, October build. I don't have the same confidence in her now, even though it started up fine the rest of the day

riguy · 03-18-2010, 11:13 AM

I just had the software update loaded in the last few days. My long cranks seems to have finally gone away. However, this is the latest release only. I've been having this issue for months and had the previous release loaded in the car with no effect. Looks like BMW may finally have solved at least some of our problems. I should note that the dealership pressure tested my fuel pump and it was @ 5 bar, which I guess is a good thing? Hopefully some of the rest of you have as good a result as I did.

5 bars? That's about 70 psi...sounds low to me for HPFP...I thought it should be over 150 bars??

GemBm · 03-18-2010, 02:02 PM

Monday morning had super long crank. No fault lights came on and car drove fine. Took it to dealer they ran diagnostics called out pump. Service tech called diagnostic info had to be sent to Munich first. HQ called back told them to load new software first and if problem persist replace HPFP. Tech seemed skeptical about software fix. Car will be ready tomorrow one way or the other. Three days without my car and no loaner available.

Mine never had a single long crank; it just 'went' during acceleration from 1st to 2nd gear...and I limped it into the shop about 3 miles away. The software upgrade/remap didn't work, so they replaced the HPFP with the 943 version. I returned the loaner and was back on the road in less that 24 hours; gas mileage seems to be better, probably due to the software update. I hear ya about the confidence issue: until the HPFP goes, there's that wondering if/when it will happen. Now, I still have a bit of that anxiety but heh...it's a car, I've got BMW Assist, AAA Premium (motorcycle as well) and a good warranty and options.

I also verified the pressure. Says pressure reached 5Bar.

Update #5: Got the car back after they replaced the HPFP. They also replaced the Leak Diagnosis Pump, stating that the "Diagnosis module for fuel tank leakage DMTL permanent malfunction." Seems to be running great so far. Hope the 943 is the fix.
