It turned out to be the High Pressure Fuel Pump. They had it back to me in 3 days and gave me a loaner in the meantime..... that was 2 days ago...... Yesterday, the orange "service engine soon" light just came on..... You are absolutely right when you told your wife it would not be like driving a Honda!...LMAO....
 
The car performs great and I was seriously considering making a purchase after the lease, however, I will really think about it now....even if I get the extended warranty plan....

Never had any of the issues mentioned with my Toyota 4X4's. I ran them all well over 100,000 miles.....
 
As for the 335i, it was not an "engine check" or "service engine soon" light. The "Navigation screen" displayed "engine malfunction" can run at reduced output. This was not the orange service light on the dash. It came on through the Navigation screen.
 
It turned out to be the High Pressure Fuel Pump..... I still am disappointed in a part failure at 11,300 miles. I am not BMW bashing, just really disappointed in the lack of reliability in that price range.

They had it 3 days and diagnosed the High Pressure Fuel Pump. That is the reason it died on the freeway. They replaced the fuel pump, the spark plugs, the fuel injectors, the micorn filter, bled the brakes and a few other things. Just got it back to days ago and it runs great, but the "service engine soon" light on the dash just went on?!?!??!?
 
What is the deal ?

Oddly enough, I had my 4runner flat bedded and nearly lemoned at 11k. But I am a fan of naturally aspirated BMW engines. Don't know what I am going to do when the lease is up now that BMW NA engines are a thing of the past.

Never had a CEL in either of my current BMWs either, both of which have 130,000 miles on them(one of which is my HPDE instructor car, by the way).
Sorry for your luck, but now it's beginning to sound like a dealer issue. The HPFP problem is not just a BMW issue, Mazda has had problems with the pump on their DISI MZR L3-VDT four (Google CDFP). Unfortunately, the quest for low emissions and increased fuel economy will make DI turbo motors almost ubiquitous- which is why my next BMW will have an S54 motor in it(either an E46 M3 or a Z4 M Coupe).

Hi 2thelimit,
 
I wonder if you can share with us the production date of your 2011 335i BMW.
I am asking because the HPFP part has been a notorious issue for several years but was supposedly fixed after rotating several variations of the HPFP and assumedly had been resolved with use of the remanufactured 1351 7 613 933 HPFP in May 2010. So it would be very helpful to understand if your vehicle was produced before that time and still equipped with one of the previous HPFP for which failure rates were high and led to general recall and replacement with part #13517616170.
At any rate you should not be having any issue related to that part. If my experience can be of any assistance I am about to finish my 4th year of satisfying driving with a 2008 335xi and the only issue I have had was a small leak in the transmission picked up 2 weeks ago (still under warranty so no cost to me).
Best of luck!

#5282 of 5349 Coolant Resevoir upper fitting by markiemark1

Feb 21, 2012 (7:32 pm)

What is the name of the elbow that is at the top of the coolant resevoir? It seems to have a pressure relief vent pointing straight upward and for some reason I'm getting coolant spray out of this relief port.
 
Any thoughts? Seems easy enough to replace this fitting, it attaches to the top of the resevoir and then to a coolant hose, I believe this hose goes to the thermostat.
 
Could there be any underlying reason why this pressure relief blew? Car has 129k miles and yes, it does have that aftermarket supercharger on it...
 
No overheating at all, it seems to lose about 1 liter of coolant when I drive it.

#5283 of 5349 o2 sensors by sabrina14

How many o2 sensors does a 2002 325i have? and is it safe to drive the car if one fails? and for how long? Also how much would it cost to get one replaced?

I think your car has the OBD-2 diagnostic system. Therefore, I'm 99% sure there are at least 2 O2 sensors on your car's exhaust - one before the catalytic converter (cat), and one after it.
 
The one behind the cat is used to assess whether the cat is working correctly or not. If that one fails, then the CEL light should come on and the relevant OBD-2 code stored, but I don't think anything should be damaged.
 
If the one ahead of the cat fails, then it could, in the extreme, cause damage the catalytic converter, which is expensive to replace. If that one fails drivability could suffer also.
 
As to cost, I'm going to go way out on a limb here . Say the O2 sensor itself costs $100. Shouldn't take more than about an hour to replace either one, so my guess would be $200. Of course, your's is a BMW so that cost could easily be 2X higher.

A 2002 325i has two pre-cat 02 sensors and two after-cat 02 sensors.
OEM equivalents from Bosch will run $95 for the pre-cat sensors and $78 fpr the after-cat pieces.
In any case the fault codes need to be read in order to determine which sensor(s) is/are flakey.
