My engine ran perfectly also and I took off and replaced the gas cap several times to no avail. it was an emissions issue according to deal that was fixed and then turned into a computer module issue.
 
Good luck....

Did you use the dealer to resolve? How much did it cost, was it an involved thing?
 
Thanks for your input. Appreciated.

I only have 16K mile son my 2008 528xi, so it is covered under warranty. The computer module itself is a $1500 part w/o the labor. Your issue should probably be coverd under warranty depending on your mileage/age of vehicle.
 
Yes, the dealer is resolving the issue after the failed reprogramming, which I am sure they tried twice.
 
Hope your issue is less involved. Between the holiday and the wait time for ordering the part, this is taking a week.
 
Good Luck!

The OBDII system will light the CEL for all sorts of minor issues that don't affect the engine: I've had it come on when there's dirt in the Mass Air Sensor and when there's a leak in the Evaporative Emissions System.

Do you happen to know how to remove the evacuator/dryer on the 540i, 1998 version? It is just below and behind the passenger headlight. Do I remove it from underneath or above? I see the round plate on top of it and the three anchoring screws. One is hard to reach with an allen wrench. Must I remove the headlight?
I can't determine how to access it from the underneath.

Who knows how to replace the evacuator/dryer? It is located just behind and below the passenger headlight. Do you have any other insights: warnings, online manuals available, etc.? Thanks.

Removing And Installing/Replacing Drier Flask For Air Conditioner
 
NOTE:
A/C system is drawn off.
Notes On Replacing Drier Bottle Or Drier Insert
 
The drier bottle or drier insert does not have to be replaced at regular service intervals in a functioning, leakproof A/C system.
 
However, the drier bottle or drier insert must be replaced without fail in the event of:
 
    * fouling of the refrigerant by filings/shavings (e.g. when the compressor is clamped)
    * a leaking A/C system or loss of refrigerant
    * the refrigerant circuit being opened for a period exceeding 24 hours , e.g. during repair work.
 
Follow instructions for dryer bottle replacement.
 
Remove complete right headlight.
Remove holder for headlight mounting.Unfasten screws.
 
NOTE: Pull pressure and intake pipes upwards and fit with plugs if A/C system remains open for longer than one hour.
 
Installation:
Replace sealing rings.Unfasten screws and pull drier flask upwards to remove.

Thank You! I just got to the dryer bottle and it is larger than the replacement offered by O'Reilly Auto Parts. Soooo....since I have not opened the system yet, and the refrigerant is not lost, I will need to ensure the compressor did not send shavings into the lines.
 
Background: I am replacing the compressor as it began knocking and recently it became loud enough to hear it inside the car driving down the highway with the windows closed.
 
New Problem: I was told there is no in-line filter screen as is found on many US systems. Is this correct? If so, how would I check for or debris/shavings from the compressor except to examine the inside of the lines where I disconnect them from the compressor?
 
Looking fwd to your response.

Yeah you're sort of doomed if you do, doomed if you don't. Generally, you wouldn't get debris unless you seize the compressor but since it was knocking, one has to wonder. You'll have to open the system to remove the dryer or replace the compressor anyway. I'd wash out the AC lines as best one can and see if there is any debris in there. If you see lots of debris, your job isn't over. You have to clean the whole damn system and replace the expansion valve as well.

I pulled the belt. The compressor is turning fine by hand. No squeaks, no drag, no serious play in the shaft.
Wash out the lines. I've never done that before.
I'm guessing you remove the lines from the car and run [what] through them? How do you dry them out again?
Thanks again Mr. S.
 
The refurbished compressor contains 1.5 oz. of ICE32 oil. I have not lost any oil. Do I need to add any?
