Recently the DSC light has started to flash occasionally while driving my 2005 Cooper S. When the light flashes it does momentarily cut the power. No other lights light up and there are no trouble codes indicated. Anyone have any ideas what could be happening? The right front hub and wheel speed sensor were both replaced not long ago but according the autoenginuity software everything is working fine.

 

Drive slower as to not engage the DSC?

 

If I were to tell you to turn that piece of *&^% off, I need to first consult my legal council for tort liability.

 

Have you done anything relative to removing the radio that could do something to the harness that connects to the toggle bank where the DSC switch is?

 

I have exactly the same issue. Hub replaced etc..
I think it's a loose plug or badly grounded, or maybe just a plain bad sensor; apparently, they are tricky to install correctly.

 

No. None of that has been touched

 

Actually I do turn it off. But sometimes I forget until it cuts the power.

 

Seriously, if a wheel speed sensor has recently been replaced, I will look into that. If your Mini is in winter road salt locality that add to likelihood the sensor may be damage from being forced into the rusty bore.

 

But what to look for? I have driven it with the laptop attached and AutoEnginuity recording and it never shows it misses a count on the wheel speed sensors.

 

What is "cut the power", car stalls?

 

You need to give a brief history of your ownership. It it is a recent acquisition, more likely than not it is just how intrusive the DSC is. If you own the Mini a long time and it only just acts up, it is more likely a hardware fault.

 

NO stall just a reduction of power consistent with the DSC kicking in

 

I bought it 4 months ago. The issue with the DSC just started a couple weeks ago. The DSC light will flicker and it pulls the power back randomly. This afternoon I was driving straight down a smooth road at 35mph when it flickered a few times.

 

So you have DSC and not ASC? Allot of times we are blindfolded when we throw answers/darts here.

 

Yes, DSC. And completely understand on the difficulty diagnosing something like this over a forum. I had hoped it might be something common that you guys had seen before.

 

Check all your plug wires and then see if there is any rust on any of the coil connections. A loose plug wire can make the DSC go off.

 

if you had a hub bearing fail you might have another one going, when the bearings fail the wheel speed sensors will fail with them it really messes with dsc, it'll think a wheel is locked up and mess with the brakes/throttle

 

The hub bearing didn't fail. I had taken the MINI to a shop to have the bushing replaced and they broke the wheel speed sensor on the right front.. They then proceeded to drill the old sensor out and managed to nick the magnetic ring on the back of the hub. After all that they then wanted to charge me another $255 to fix the hub that they screwed up. So I replaced the hub.

 

holy crap that's a train wreck from the start

when your dsc goes off, are you cornering or just driving straight at a normal pace in traffic?

 

It is random. Today I forgot to turn the DSC off again after I stopped at the bank. After that the DSC flickered a few times while driving at a constant 35mph on a nice smooth straight road

 

Here is the coil I just took off the car. Luckily a local Advance auto parts had a replacement coil and plug wire set in stock. Changed coil, plug wires and plugs. I also did a computer reset. I hope it helps

 

Well nothing has changed. While it does idle better now I am still getting the intermittent DSC light.

 

It is possible the DSC switch maybe bad and vibrations may be making it flicker. There is no good way to test intermittent problems, unless you can test on the fly.
That switch is important to the DSC circuit and is responsible for the many things tied to it's working properly.

 

If it is an issue with the switch, wouldn't the DSC be turning off when the light flickers? When the light flickers it pulls the power back like the DSC is activating.

 

If the switch is faulty, vibrations in the milliseconds may, or may not cause an effect. If something got spilled on it, this could do it also.
The plugs on the wheel sensors may also have corroded pins and this could cause the same effect.
