Hi guys.

Hope some one can help me . I got this E39 1997 R REG 523I SE . A ll it keeps doing is stalling when I come to traffic lights. I called the AA out and he took the Mass Air Filter sensor off and it started , but after a while it kept stalling. Can anyone help or got any ideas on why it keeps doing this.

My Dad went to see the dealed i got it from and he didn't seem to have a clue. it also rattles when i pull off and the air bag red warning light is constantly on . HELP PLEASE.

I have waited ages to get a BMW and I hope I have not been sold a dud.

When was the Lambda sensor last changed? They only last a set period.

Take a look in the engine bay for any split/leaking hoses.

If you have just bought this, I would run some Catcleaner through the engine, see bottle for instructions, and then burn a tank of Shell V Power to clean things up.

An umber of things can cause this.

Get back to Ian on your location as his offering a good service.

Sounds to me like a vacuum leak and/or a possible sticky throttle body. Get yourself a can of Carb-Cleaner and start cleaning bits within the respiratory system.

I had a similar problem with my 5 series 528. The problem was resolved when the prop shaft sensor was replaced. the sensor governs the fuel into the engine. Secondly the reason for the seat belt light to show in the dash relates to the loom cable under the seat either the passenger seat or driver's. Whilst they can be repaired you may ultimately require a new one. Hope the answer helps.

Yep, dirty sensors indeed... Clean the MAF (do not touch the sensor), check ALL intake and breather hoses for oil ingress or poor connections ;)

This man is on the ball, defo sounds like a vacuum leak. (most likely after the MAF)

      Tyres..what's the best alternative to run flats

      Hi Dave, thanks for your fantastic reply. I'm on a staggered set and I recall the wheel shop retailer was concerned about the M40d brake calipers and the 19" space saver not fitting 21" wheel. Hmmm, been researching more, and people either love or hate RFTs, think I'm stuck with them until pcp runs out in Dec 2025, but I'm now nervous about long journeys abroad cos each time I have a sidewall blow out, there's no way to run the car for any distance without wrecking the rims...

      Tyres..what's the best alternative to run flats

      Hi Jon Welcome to the Forum First is your car fitted with a Square wheel set (same size rims front and rear) or a Staggered wheel set (Wider rear wheels than the front) I suspect your car will have a staggered set probably 8j Front and 9.5j rear, so fitting a space saver wheel/tyre will mean there will be a different rolling radius on one wheel which can cause damage to the Transfer case and or diffs quite quickly if driven on for any distance (probably why your Dealer was vague) Even if your car has a square set up if the rolling radius of one tyre is different damage can occur. It isn't just BMW who suffer from this many 4x4 cars have the same issue. First you would need to check the Off Set to make sure the 19" wheel clears your Brake callipers and fits in the boot along with a Jack and wheel brace. Then if you are sure it is only a real emergency measure and not a solution that will allow a distance to be covered and aware of the risks why not. I have 2 x X5;s both run 20" staggered wheels and early in their lives I changed run flats for standard tyres (as generally they are easier to source and wider choice, care still needs to be taken that front and rear Rolling Radius are closely matched) and I keep a small compressor and Tyre goo in the car in case (BMW actually supply these as well). I have used it twice and happy to say not on my car but to help out others. Hope this helps not confuses Dave

      Tyres..what's the best alternative to run flats

      Hi guys, appreciate this topic is a bit dated, but within 6 months of owning my X3 M40d on 21" factory fitted run flats, and the state of our A & B roads, I've shelled out £700 on TWO tyres, due to the sidewall rupturing, leaving me stranded roadside and in need of a flatbed...not good. I'm looking for a back-up plan as we tour long distances on holiday and found an X3 space saver, claiming it fits all size wheels. BMW dealer was vague when I asked if it would fit....no surprise. The Wheel Shop said...check with the dealer. Wondering if anyone out there has more experience. Thanks all 19" BMW X3 G01 | Space Saver Wheel | The Wheel Shop

      Discs and pads

      Hi Dave, I’ve actually gone for EBC grooved discs with yellowstuff pads. Just thought it would look a little beefier whilst still benefitting from good performance and longevity. Stu👍
