Baffling - Engine Malfunction With a New (to us) BMW X5 35i
 
Help! we bought a certified pre-owned 2013 BMW X5 35i e70 several months ago. Yesterday I took it up into the mountains for the first time (generally light highway driving but up to 10,000 ft.)

After returning, I heard a noise that sounded like my front brakes had reached their warning strips (today I pulled off the tires and the brakes are nearly new). The sound came in and out.

Picked up the wife, continued hearing the (false) break noise. Drove a mile, parked for 10 minutes, restarted the car. Got a check engine light about then, but was too busy with traffic to pay it any attention.

Soon as we hit stop-and-go traffic after about a half mile there was an intense burning plastic or battery acid smell.

We managed to get it back to the house on "reduced power" mode. After looking at it all day today I haven't found any noticeable burning or leaking.


I did get a scan tool on it, and am getting a whole bunch of misfire codes:15DF,0301,0302,0300,10F5,0087,
codes_p:0172,

Any tips would be appreciated. Hoping to at least ID this error before taking it to a dealership.

Thanks!!!

Bunch of misfire codes (30xx), some low fuel pressure codes (0172, 15DF).


One Ive never seen and cannot pull up: 10F5


The burning smell is odd. is is the false brake noise... check your drive belts? All good? FRM issue maybe? But that wouldnt make noise... hmmm



You've got the CPO...bring it in. I would NOT tell them 'i kept driving after the warning and smells'. Or at least downplay it.


"CEL came on, I brought it in"

I'm wondering how you know what battery acid smells like. Not being a smart-ass, genuinely interested.

Trying to think how a metallic/scraping noise could result in a burning odor and then a CEL. Do you have the ability to see when the misfires occurred?

I was thinking if you might have a mechanical problem with your alternator. That might cause a metallic noise and a burning plastic or even electric odor. Not sure how the misfires or fuel pump issues are related but obviously fuel issues could cause misfires and misfires are sensed using, among other things, knock sensors.

Ha! I learned what battery acid smells like when I'd replace ancient batteries in tractors and old cars. Still, no leaks found in and around the battery, I think it's something else burning.

I think the word you wanted was 'acrid' smell?


Report back w what the dealer says...


(I learned what battery acid smelled like when an old VW had a failed voltage regulator, blew out cell covers on the battery (which is under the rear seat. Friggn mess. Cleaned it with baking soda to neutralize the acide on the underside of the seat. ;) )

I learned what battery acid smells like pouring acid, activating new batteries, charging and discharging them. Big batteries; couple hundred thousand pounds, a few thousand gallons of acid. Big batteries.

On my 35d the vibration damper on the front of the crankshaft failed and caused a bunch of smoke. Doesn't smell great either but at the time I did not check for codes as I fairy quickly figured out what had happened. I noticed that the serp belt was nearly stopped but when I turned the A/C off things started to spin again. Maybe worth checking tho I don't know if damper failure is an issue on the 35i.

[Partially Solved] - Update!
 
I have an update. The dealership located a fracture in an air line, photos below.

Trouble is, they are saying that an injector has been damaged, and the smell was from gasoline fouling the spark plugs. They quoted me a set of six for nearly $2500! The wife and I nearly fell over.

Hoping someone out there has an idea what new injectors and plugs ought to be cost us - help!

They are simply scamming you. You are clearly looking like a 'mark', and they are confusing you and stealing your money.



Have they put anything in writing?


Scammers will typically have very little in writing, but will spin the nonsense around what caused it in their verbal pitch.




Since you dont know much about cars, you are kinda stuck- you decide there must be SOME truth, and then spend your time lost in the weeds... (So how much SHOULD an injector and plug change cost???)


The 'smell' was 'gas fouling the plugs'?!?!?


Finally, this is a CPO a few months ago- all this is under CPO warranty, right?????


Please dont move forward- this needs a second opinion.

Start with simple stuff.. misfires could be due to air/fuel ratio disturbed by cracked hose..
change the hose.. clear the codes.. and give it a trial .. if still injectors.. use the CPO card in their faces..

Anyone want to tell OP that his picture is NOT an 'air intake'?


Its a PCV hose:

Maybe $40?

Why are the injectors not covered under CPO? The broken hose is just a vent from the top of the engine back into the intake to capture small amounts of emissions. That hose being broken is the equivalent of driving around with your oil cap off. It is not something that will cause damage.

Reminds me of the old stories when there still were attendants at service stations.


Driver would pull up, "fill it up".... attendant would say "Check the oil sir?"


Next thing you know there is an oil leak under the car (a small oil can slipped back into the pocket) of a cracked/cut/broken hose.... and a concerned attendant advising "our garage better take a look- you dont wanna get stranded"






I mean sure, at a grimy station off a no-name exit...but can this happen in a building with "BMW" on the front!??!

Vonbimmer 02-08-2019 07:24 PM

I just replaced that hose on my 13’ and as others have mentioned it feeds the crank case gases into the intake track on its way to the turbo. I’m sure it could cause the air fuel mix to be inaccurate but I’d be surprised if it damaged injectors

Wonder what the OP is doing?

Swing by CVS for some vasoline on their way to the dealer??
