Limp Mode - Many codes

[kungpao]

Thanks Ard I was hoping you'd reply to this My SA is a total Ditz...

I can't get a straight answer from her and our current discussion is hell bent on me buying a new filter from her.

Back story:

several months ago, the x5 threw a cel for open circuit in glow plug cylinder 1. I took it to my independent and he replaced the glow plug but no joy in clearing the code so his next step was going to be to change out the controller. After some discussion, he suggested that it wasn't a necessity at this point and that I could drive the vehicle.

About a month later, She went into limp mode when downshifting as I was leaving my house. I turned around and parked her in the garage for another month till I had time to deal with it. (drove my other vehicle)

Now the time has come where I need the vehicle so I'm dealing with it. Battery had died in my garage so I jumped it and that's when I got to read the codes.

I had it towed to the dealership and that's where it sits. I'm asking my SA for detailed info: "Trouble Code - Remedy for trouble code - Is it covered/why/why not" Her responses are vague:

I was actaully just in the back with the technician, we got the intake manifold off and checked everything, the good news is the cylinder head is not clogged, and we were able to check two other sensors that are faulted and are covered under the extended warranty, but i probably will not get them until tomorrow. To do the carbon blast on the cylinder head is not a covered component under the extended warranty, it doesnt cover regular wear or anything due to an outside source. usually its caused from bad gas, so that is not something that BMW will cover. But we dont have to do that now anyways, so thats good. the sensors that are faulted are the exhaust back pressure sensor and the charge pressure snesor that are internally faulted, but you do need to replace the air filter is crunched and not letting enough air get through, and i have to replace that so warranty doesnt see that that is also causing an issue since thats not covered, there will be no etra labor since im already in there, but the part is 57.91, so if its ok i would like to replace that as well. right now the only cost to you are the 50.00 deductible fot the covered items, the 57.91 for the air filter and the 220.00 for us to take the intake manifold apart to inspect the components. Im down to two faults right now which is good, so hopefully once all this is done, we will have no more faults!!

the faults i had for the mas airflow and pressure faults were 03ff0 and 004862, but they will not come up on a search

anyhow, if you have any other questions, please lt me know and if its ok to change the filter, and hold the car for the parts tomorrow

thanks!

She's adamant that not replacing the filter will cause a fault so my last message to her asked if that fault would prevent me from driving the vehicle. I know.. I know.. it's just $57 but I'm having a hard time swallowing $57 for a $20 Mann Filter. Hell I could swap it out for a K&N for that.


Edit: Oh yeah her explanation for the battery was that the one in the vehicle has lower voltage than what it's supposed to have which doesn't make any sense whatsoever. I've asked for an explanation so that I can go back to the dealership I bought it from but she hasn't answered. I can only assume she meant to say wrong amperage.
