I have a Eura Mobil on a 316 Sprintmatic chassis. I had been at racing all over the weekend and decided to travel home early in the morning to get around the M25 before the rush. I therefore left the site at 0330.
It had rained all the previous day and consequently the inside of the windscreen was misty. I wiped this all over with a towel and then set off. The first 25 miles was on a dual carriageway before meeting the motorway.
I had the de-mister on full blast and additionally the separate front heater fan was on cold air. After about 20 miles the screen was still misted up bar a small circle directly in front of me. I therefore decided to stop in a lay-by and give the screen another wipe with the towel, which I did with the engine running.
I then pulled away in auto, got to about 30mph and the engine cut out and I drifted to a halt in the inside lane. Due to the very early time there was little traffic, just the occasional 40 ton artic!
I managed to get the engine running again and pulled away again, and the same thing happened again. This time I was expecting it and managed to pull half onto the verge.
I then noticed the the ASR switch was brightly illuminated, which I have never seen before. Pressing this did not change the illumination. After a lot of cranking the engine started again and I gingerly pulled away. I then drove a further 200 miles, including two stops, without any further problems.
At my breakfast stop I read the ASR bits in the handbook and see that there is a power limiting component in this.
My guess is that whilst cleaning the screen in the lay-by I lent against the ASR switch for some time, maybe 10 seconds. I am assuming this put the ECU into some sort of brainstorm. After pulling away the final time I noticed that the ASR switch was not illuminated anymore.
The ASR is the anti skid system, also known by other acronyms such as ESP,DTC,DSTC, all done by Bosch. In the event of a skid the first thing it does is reduce torque to the driven wheels then if neccessary applies brakes independently to stabilise the vehicle and bring it back under your control. The system is enabled whilst ever the vehicle is being driven, by default, pressing the button on the dash switches it off (actually it reduces its effectiveness, you can`t turn it fully off) the light or symbol comes on to tell you such.
So pressing the button will actually give you full power not reduce it.
I would suggest taking in to the garage for a code read to find out what the actual problem is/was.
By the way the reason you would switch it off is to allow the vehicle to pull away from a standstill on very slippery ground, if the system was in effect it would detect the wheelspin and the vehicle moving from side to side,thinks its skidding and shuts down the power so you go nowhere, by pressing the button you get full power to the wheels allowing you to try and manouevre away.
I demonstrate the system as part of my job with manufacturer dealer training.

"The ASR is the anti skid system, also known by other acronyms such as ESP,DTC,DSTC,"
If it is know as ESP then that is wrong as is the DTC DSTC.
These are stability programs. Of which ASR can be one of.
ASR stands for Anti-Slip Regulation
If a Vehicle has ASR it does not mean it has ESP.
If a Vehicle has ESP then it wil have ASR as part of the Program
Not all the stability programs are Bosch. ESP is manufactured by Bosch but the Trademark ESP® is owned by Daimler AG.

Hi TM, the acronym ASR is used by Renault as well but basically they all do the same thing, if Daimler AG own the copyright, do Ford licence it off them?
ESP =Electronic Stability Programme(Merc +Ford),DTC =Dynamic Traction Control (BMW), DSTC = Dynamic Stability Traction Control (VOLVO).
Whatever it says on the button,whenever we are demonstrating it we have to turn it off to get the car to skid then turn it back on again to show how it prevents it.
I ain`t getting into a slanging match about who owns what or what this and that stands for, I`m only going by my exeriences and what I`m told by the manufacturer I`m working for at the time.

Hello,
I was more clarifying that anyone who has ASR should not assume they have ESP or similar Stability Programs. ASR is a Traction control system that can also form part of a Stability Control System.
When I worked with Renault a few years ago, their stability program was called ASR (Anti Slip Regulation = Slip/Skid ,Regulation/Regulate/Control = Anti Skid Control).
Helped reduce understeer by reducing torque and nipping the inside brake, very affective.

Thanks to all who have contributed some of the technical detail, (and TLA's) relating to ASR systems.
I have now carried another another holiday trip. This went without any problems occurring with the engine pulling fine, whilst towing a car as well.
I therefore must come back to my original thoughts that I caused situation this myself by leaning against the ASR switch whilst wiping the inside of the windscreen.
If I have to do this operation again, and I'm sure it will re-occur with some more very early starts I will be making, I will turn the ignition off whilst I carry this out.
