Just bought my first bmw today! mixed feelings of excited and nervous.
Soon after i drove away with my $3000 initial investment the "Service engine soon" light comes on..
Luckily i have mechanically inclined friends that can help me through this endeavor.
I will update you all on what the issue is tomorrow...
The car to me seems like it still has some life left in it..
It has 116K miles on it and some small cosmetic issues which to me would be expected in a 15 year old car..
The one button that take all 4 windows down or up doesnt function so i have to lower each window with the individual buttons (a $78 part to fix i found)
The shifter is chipped n broken ($59 replacement part i saw on ebay)
the driver door doesnt unlock when i hit the unlock button i have to use my key to manually open the lock.
The top works great ! small inside tear in the fabric but doesnt affect any function or possibility of leaks
Before i tackle any of these small issues i need to see what the codes read tomorrow when i get it checked.
it was inspected 2 months ago so im hoping its nothing major (fingers crossed)
Drives great from what i can tell.. Small occasional clunky kind of sound coming from front left tire area. will have that checked out by my buddy as well..
Sorry to talk to much like i said mildly nervous and anxious to see what the issues could be. Thanks for letting me rant. Have a great night!
Congrats! You did the right thing. Go to autozone borrow their code reader and figure out what codes are triggering the check engine light.

[QUOTE=charter21p5;30067821]Congrats! You did the right thing. Go to autozone borrow their code reader and figure out what codes are triggering the check engine light.
Yes i did! here is what the codes came up with
p0171 p0174 p1085 p1083
System too lean bank 1 and 2
Fuel Control limit mixture too lean bank 2 sensor 1
Fuel Control limit mixture too lean bank 1 sensor 1
I was told maybe vacuum leak? or 02 sensors?
any and all suggestions would help. thanks!
It’s a great car when it’s running right. If the top is working, that’s a huge win.
Now, assuming you don’t have any service records?
I’m more proactive on my maintenance, so assuming these things have not been done, I would do the following:
Valve cover gasket, spark plugs, coils, rebuild DISA valve, replace all hoses and belts including CCV hoses and secondary air pump hoses.
I would also recommend (but not as required as above) replacing the water pump, thermostat, radiator and switching the mechanical fan to an electric fan set up. But now that’s getting really proactive.
Good luck and welcome to the club!

First things first,
have an intake smoke test performed,
to verify location and cause of intake leak.
Sorry,
forgot to welcome you to the club,
I own a convertible myself, I'm sure you'll enjoy your new purchase!
Thanks for the replies Guys!
Adwebinc: I am planning on doing some of the suggested maintenance you listed. i just want to see where this vacuum leak is coming from! driving me bonkers
It does have some service records seems decently maintained. I did have a friend of mine who owns an older 330ci convertible and he says his came up with the same codes. hes going to look deeper into mine for me... He did go out to my car with me and show me something interesting.
He took the air intake box and jiggled it a little and the engine cut off? so there is definitely a vacuum leak somewhere where something is either punctured or not fully sealed... He also said one of those codes i listed above is one of two things.. 1 water may have gotten mixed into the engine? or 2 they previous owner used really cheap gas? i was told use sunoco gas from now on.
He cleared all the codes and wants me to drive it and see what pops back up and hes gonna check it all again for me in a few days.
thanks again for the warm welcoming here and im excited to learn more about the BMW world and maybe do some DIYs in the near future. thanks again!

INTAKE leak.
If smoke test is not possible, try this shortcut,
Remove intake airbox, then remove rubber intake boot,
squeeze and carefully inspect boot for cracks, if any-REPLACE.
After replacement clear codes, test if they return.

"INTAKE leak.

Thats going to be my initial step today... On saturday i drove it to work after having all codes cleared the day before and on my way in they came back on.
Then as i was sitting in the parking lot at work my RPMs irregularly were going up n down and at one point i even thought it was going to stall out so its definitely getting more serious imo.
thanks again for the help and tips and ill check back once i check for the intake leak(s).
**UPDATE***
giant Slice in the MAF Air intake hose. this is the culprit for all my codes. Ordered a new one today on amazon (with prime shipping lol) 20$ part
Also ordered Complete front strut and 2 rear shocks kit my buddy said it was needed. $180 for the set
1 new tire $100
and thats it! The only thing he said to keep an eye on is a slight leak in the rear diff. but other then that it has a clean bill of health! He is doing all the labor for the above parts for $100
Thanks again for all the support and ill upload some pictures when shes all fixed up!

Nice and easy when locations are pinpointed,
and you have a cool buddy to rely on for labor!
What is the location of the diff leak?
Point it out here:https://www.realoem.com/bmw/enUS/sho...diagId=33_1185
or here:https://www.realoem.com/bmw/enUS/sho...diagId=33_1034
I never really got my guy to look deep into it since he didnt seem to concerned about it.. this is the pic he took to show me . he said he can see a residue on the outside portion of the rear diff.
He recommended something like a de-grease and dye? not exactly sure what that means but here is the pic.

Yea doesn't look bad, I guess I would clean it up with degreaser,much easier to spot leak locations.
Seems like gasket #2 is failing:https://www.realoem.com/bmw/enUS/sho...diagId=33_1034
I suggest replacing that gasket, and performing a fluid change.
*UPDATE*
it was the hose connected to the mass flow intake. it was dry rotted on the bottom so i replaced that and all my lights when off after a few days . also put new struts and shocks on and new spark plugs and its driving like a dream. super fun car. not upset with my investment at all.
Cool,enjoy!
