Does anyone know to which airbag is 09 side airbag fault is related to? It is for an early E38 - 1997 - 735i series. 

Many thanks

 

 

Hi Dimitri

Take a look at www.realoem.com classic section you should find what your looking for there

Dave

I did, I cant see a link between the fualt codes and the part number.

First the battery is in good condition ?

I spoke to a friend who works for BMW in the USA he tells me that this code is often riggered when work is carried out on orther components such as Steering Wheel or the Instrument cluster.

He sent me the attached hope it helps

Good morning Dave

Thank you for your response. I did have some work done but none was in the steering wheel or instrument cluster. I do have an airbag code 09 "Side airbag, front right" on that I have not managed to clear out yet.

I did clear the fault codes 2-3 times which it did remove most of the fault codes apart from 3,

09 Side air bag, front right

28 thermal sensor for oillevel defect - BTW my vehicle does not have a oil thermal sensor

94 LED for anti-theft alarm system open circuit - BTW the red light that is on the top of the dash has never been ON.

Hi Demitri

Your car has an Air Bag in each door so front right would be in the Drivers Door (UK) Passenger Door (LHD) I would check the Loom connections continuity through the door it could be a broken wire in the loom (make sure you disconnect the battery first) 

The other faults could be as simple as a corroded pin or poor earth, the Thermal Oil sensor fault may clear when earths and other connectors are cleaned up

Do you have INPA or BMW 1.4.0 they will help a lot

Dave

Hello Dave

Thank you for the respose.

I will try to locate the connector and clean them up. Could it be the head air bag and not the door air bag that is faulty? (BTW the car is a LHD).

Considering there is no oil thermal sensor could the “Thermal Oillevel Sensor” be a faulty oil level sensor?

I have tried to instal the 1.4.0 on my laptop but I gave up after 3 hrs in trying. I could not find the correct drivers for the software.

Yes worth checking the Curtain Airbag as well BMW also love muliple Earth points my 4.4 had several difficult to trace faults that eventually I found an earth point in the back of the Boot/Trunk that was showing signs of rust around the mounting bolt took it off cleaned itput electrical contact paste on it and bolted it back,fixed lots of stuff. I went through the car and did all the earth points.

With 1.4.0 did you download the program or load it from a disc ? The disc should have Drivers on it Load program then plug in the Connecting lead (Not connected to the Car) you should then see a prompt to load the drivers the n your good to go.

As I have the program up and running if you want a 20year old disc I am happy to post it to you

Dave

Good morning Dave

I can’t thank you enough for your help.

Although I don’t think it’s an earth issue, the car lived all its life in the Med and away from the sea and its very clean both inside and outside, I will try to trace all earth points and see if this will sort out the fault codes that I see.

Considering I have no fault on the dash, does it worth replacing the oil level sensor or not?

Regarding the 1.4.0 I got the CD cable and plug and tried it to a windows 10 - 64bit laptop and on a 16bit Windows vista, downloaded drives from the net and tried drivers that I had on the disc without luck. I have found other suppliers of the 1.4.0 who include a 64bit windows 10 driver in their disc that I will try in the near future, August.

What windows version you use?

 

Thanks

Dimitri

Hi dimitri. 
I have a copy on windows 7 and it works fine. 
 

Hi Stu,

I guess I need to get a windows 7 laptop set up just for this.

Hi Dimitri

Like Stu I have an old Windows 7 Lap top that I use only for Diagnostics it is a bit overworked as I have Programs for Volvo, Mercedes Star, BMW 1.4.0 and INPA on there, I really must upgrade the memory one day 😁 I have a full INPA/ISTA program but that runs on a different lap top with a bigger hard drive and plenty of memory (ISTA is a big program) 

I set 1.4.0 up for a neighbour by setting a Virtual Machine up on his laptop then setting up Windows 7 then load i.4.0 just make sure Win 7 is in 32bit mode 

Good Luck 

Dave

Hello Dave.

maybe having 2 operating systems is the solution.

Many thanks

Dimitri

Hello all, on the topic of the failure code 28 "oil thermal sensor oil level defect", considering this is an early vehicle that does not have an oil thermal sensor, and I do not have a fault on the dash, is the fault above an oil level fault and not an oil thermal sensor?

I have read that if the oil level sensor fails the car will not start. is this true?

Many thanks all for the great support!!

Dimitri

Not unusual for the oil level sensor to fail but never heard of one stopping the engine starting, though it does sound logical 

I changed 3 on the 4.6is but you have to wait until Oil Change as they are in the bottom of the sump

Dave

Hello Dave.

I don’t know if it will stop the engine from running, I read it in one of the BMW forums.

The strange thing is that I don’t get a fault on my dash!! only on the OBD.

I got my first 735 last August, loved it from the first ride, and now I am trying to fix all those little things that the main BMW dealer have not bothered to put right, hence my questions. Almost there!! 

Many thanks

Dimitri

Morning Dimitri

I believe if the oil is below safe levels it may prevent engine start and show an oil warning but if it isn't working !!! 

Unfortunately many Main Dealers (not just BMW) loose interest after their Warranty Responsibility ends. So unless a Diagnostic scan is called for and paid for they do not do them and even if they find something which doesn't have an effect on day to day running it gets ignored or for gotten.

As I said my 4.6is I fitted 3 Oil level sensors before it was fixed. The car had a full BMW history when I scanned the car that fault was there when I asked the dealer they knew about it but pointed out the sensor can only sensibly be changed at the next Oil Service and the Dip Stick allows oil level checks. I also had an AUC sensor fault Dealer again was not concerned but for me if it's there it needs to be working.

Enjoy your Beemer

Good morning Dave

True, the one I got ad 79k, full BMW service history and I had to replace almost all gaskets, o rings, hoses, abs sensors, seals, and I still don’t have a fault free car.

Although I have just serviced the car, it looks that I should replace the oil sensor just to be on the safe side, I am using the car for family holidays so the last thing I want is to be stranded.

Thank you for the support. Very much appreciated!!

Take care

Dimitri
