Hi Guys

I have a 1989 635CSI that will not hold charge..

I have replaced the battery and altenator but when i drive lights start to go dim then when i stop it wont start as no charge.

Any ideas/common faults?

Thanks

Tim

First job (easiest) is to check and tighten ALL the earth-leads/straps... Often this will cure it.


Next job, run the engine and test the voltages with a meter (anywhere theres a positive), test on a few different locations to eliminate broken connections.


Finally, if no solution so far, check relays and regulator for operation/connections... Go back to second job !



Just a simple method HTH

      Clicking noise when disengaging the clutch,

      Clicking noise when disengaging clutch either when pulling off or changing gear, happens more in lower gears but can still happen in higher gears. if sat with engine running, in gear and handbrake on, and slowly release the clutch until it’s hitting point I will make the clicking noise aswell any ideas as to if this is serious or just a common bmw noise?

      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👍
