Hi MakaveliFaison,
I changed my FA in CAS and LMA but haven't coded it with Progman. Did you use Progman to code your 02 e65 or did you just use NCS.
Thanks,
fratan

The real question is did he flash his DME to bypass the secondary air. The reports that I'm getting is that is the only way. I coded my e65 today and changed my vo to gl61 and then went into the mmig modules and changed us_11 to ece_11 and then from us to ece. This renoved the legal disclaimer but I doubt it will fix the 0492 code, only time will tell.

Could someone pm me the dealer for the german software? I have been working on the clogged air passages for the secondary air system but with no luck. I changed my car over to gl61 on my FA string and rerwrote it back in CAS and also recoded my MMGI module to euro. I was able to get rid of my legal disclaimer but I just got the 2760 and 2761 codes back. The interesting thing is that I've gone through 8 drive cycles and the evap and secondary air sensors won't reset for the smog test. If I could get the secondary air to reset then I would be good to go.
This Saturday my son will try and unclogged the secondary air passages going into the back of the engine.
If anyone has any other ideas, that would be great.

Greetings all... after reading this thread, it seems to have gotten a little diluted from it's principle resolution, clearing the P0491 Fault Code permanently through the reprogramming of a particular module, with a particular piece of software...

My questions are these, since I'm probably not the only that wants to, or will want to know....

1) What is the name of the software? (if known)
2) Where can it be found for purchase? (if known)
3) if 1 & 2 are unknown, what is the name/city of an Indy shop who has it so they can be contacted? (anyone?)
4) What module needs to be reprogrammed to bypass this test on startup (if known)
and 5) what value in this module needs to be changed? (if known)

I was trying to find out the same information but with no luck. After reading several threads, I believe there is a program from Germany that an Indy shop in Vancover has. I live on Cape Cod so that isn't going to happen.
I have also read that you can change the vehicle order on your car to euro spec and then flash your DME to Euro 3 or Euro 4 which would bypass the secondary air but haven't tried this method yet.
In about a week, I should know if my wifes 04 745i SES has been fixed. The 0491 and 0492 codes have been an issue since Dec. 15, yearly inspection, caused by broken valve stem seals. We have just finished doing the carbon cleaner method posted by Robz_745 which is to fill the air valve ports with seaform and b12 cleaner and then using a wire and air compressor to try and clear 1 or more ports of the SAS without removing the intake or the heads.
We were able to get air movement to the tailpipe after 3 days and 4 cans of carbon cleaner. Robz 745 has had success with this method and he has stated that it has been awhile since the SES codes have appeared. I'm waiting on my results.
Hope other people post as well.

Update on the secondary air codes

Update, 500 miles driven and I'm still waiting for my ready monitors to set for inspection. So far no pending codes for secondary air. I'm keeping my fingers crossed that we got air flowing through the system without having to remove the heads air intake. Robz_745 should have a DIY done soon.

The secondary air monitor will be the last to set. You are not yet home free unfortunately. The reason why the readiness monitors are not yet set (especially after 500 miles) is likely because the secondary air is still going through it's checks becuase of the problem associated with it.

Hi Roadffrog,
On this 04 745 the evap system is the last to reset. The reason that I know this is because at my last state inspection the secondary air was ready but the evap system was not ready. At that inspection there was a pending code which was 0492 which failed the inspection.
I've been working on this since December and usually by now I would get a pending code in my scan tool but we'll know for sure in the next day or so. If the SES light comes on then I'll know the fixed didn't work but I have good indications that it did work. Do you still have carbon build up on your car?
Thanks,
Phil

Hello Roadffrog and Fratan,
I've been following this thread with special interest since my o2 745 has the same issue. Its my understanding that the Secondary air flow monitor, since it is a cold start function, resets to Ready if after 4 successful cold starts are performed without a problem. It has nothing to do with the mileage. I reset mine once drove almost 600 miles without a cold start and the SEL light stayed off until after the 4th. start . This has been a consistenet event everytime I've reset the light.
Anyone know how swithching over to the Euro 3/4 setup is working?

Hi adboles,
So far I have a minimum of 10 cold starts. The last time that I was trying to reset the monitors it took a long time on this 04 745i. The last time that I tried to reset the monitors the 0491 and 0492 was showing pending code after a couple hundred miles. Then after a long time, about 700 miles, I was driving and the SES light popped on. This was due to the pending codes for SAS.
As far as the Euro mode goes, you would need to flash the DME to Euro 3 or Euro 4 after you change your FA STRING TO GL61 FROM GL63 USING ncs EXPERT. I haven't gotten that far and it is possibility that this may not work either. Look up flashing DME to Euro spec's.

I'll keep everyone informed once my secondary air resets. On my car the evap is the last monitor to reset so when the secondary resets then I'll take it down for inspection. So far 500 miles and no pending codes.

Hey Itialiano,
You shouldn't have taken a bath because of worn out valve stems seals. Most V 8's valve stem seals need to be replaced sooner or later. If you look around on the road most cars valve stem seals go after 100,000 miles if not sooner. I try not to idle so it really doesn't bother me. When it does, I'll get someone to fix it. 40 hour job @ 100.00 per hour is $4000.00. You can probably get a decent mechanic to do it for $ 2000.00 but a little smoke doesn't bother me too. I noticed my 2006 is starting to smoke a little as well.

Alpinaman,
Are you referring to the air valves which connects to the secondary air ports on the engine block? Those were replaced as well as the y pipe that they are attached to. Does anyone know why the evap system doesn't reset? I check my inspection from last year and the evap system wasn't ready but I passed because the sas was ready.

the evap monitor is tricky .. but usually the car needs to see all levels of fuel full tank half tank .. etc .. now some bmw im not sure if its yours under state of california law these cars have recalls .. procedure basicaly involces a reprogram so that the monitor for the evap is ready .

if its still not becoming ready there must be a problem somewhere but another sensor or switch is countering , once that countering perameter has exceeded it will most likely throw a MIL light

Update to Secondary Air System SAS light

Good Evening,
This is an update to the SAS light coming on to a '04 745I. I have driven another 1200 miles and decided to check my ready monitors which I've been doing on a daily basis. Tonight the evap system is ready and only the secondary air is not ready. Tomorrow morning, I'm heading down to the inspection station to get an inspection sticker.
There is a fix now for the 0491 and 0492 trouble codes. I'm the second case which worked. The fix is part of another thread. The way that I got the EVAP system to be ready was to fill the car up with gas. Thanks for the great tip.

As I thought, my inspection with the Massachusetts RMV went flawless and I have a new inspection spection sticker on my wife's '04 745 I. The only monitor that I'm waiting for is the Secoondary Air monitor. When that monitor becomes ready I'll let everyone know the result.

As far as I'm concerned, this is a fix for the Secondary Air trouble codes, 0491 and 0492. Next project will be those problematic valve stem seals. This car rides like the wind.

Hopefully, I can get my son to do it for a set price since its a 40 hour job. He thinks he may have to take the Cam's off to fix the seals? Is that the case?

That's great news Fratan! Glad you also had success. I'm still free of any codes as well and probably at least 3k miles in. I agree now that the fix worked (at least for 2 of us). Haven't had a chance to work on the DIY to share yet between work family and other obligations, but still plan to. Like you said earlier, most is in these threads.
Valve stem seals - I believe this is the root of our SAS problem. I did them myself last November. I didn't take the heads off but you'll need to remove the cams and you should use the proper gauge to set them back up. Honestly I think the hardest part form me was getting the valve covers on and off. Used air and spark plug adapter to keep the valves up. Total cost about $500 and I learned to pronounce a few choice new words!

Thanks for the input on the valve stem seals. My son thought that he would need to remove the Cams so I'll pass that pieice of info over to him. I like the style of this 04 745 so I'm thinking of selling my 06 750i and take this car off my wife's hands since those seals need fixing.
It has been a couple of months working on this and what a relief when the car finally passed.
Thanks for your help and advice about soaking the chambers for a few days. You definetly need time and patience to fix it.
Regards
Phil

Update of SES problem


I just checked to see if the Secondary Air monitor came up as ready and sure enough the monitor came up ready with no codes for low secondary air flow. codes 0491 and 0492 for

This was the last test for the fix for SES problem without having to remove the heads. Great job by robz 745 and my son Brandon for doing the work and making a nice tool for the air compressor.

Well now. looks like I may have a project this Summer! Good job Fratan!! Are you going to post an offical how-to, so we can petition to have it posted in the DIY section?

Hey Guys,
This week, I went to my INDY mechanic, and he reset the CEL light for me and told me to drive the car for at least 50 miles and come back the same day. I drove 54 miles went back to the INDY and he looked for codes and Not Ready monitors with the OBD tester. I still showed the 0491 and 0492 codes, but only one Monitor displayed as not ready! So, he said to go straight to the testing station and I did. Since the CEL light had not reset yet, they tested my car and gave me a pass slip. My county allows 1 not ready monitor. I don't know what your states require, but up until this week, I didn't think I could get a pass slip if any Not Ready monitors were displayed. I hope this helps, it sure put a smile on my face.
