    Hi The ASD warning light has just come on on my W140 2.8 and also the warning triangle, but goes out when the brake pedal is pressed. I have checked the brake fluid level and it is at the correct level. Can anyone please help?

    Yes both the triangle warning light in the dial and dash light stay on when the engine is started but goes out when the brake pedal is pressed and on again when released. It only started tonight, at first i think the triangle light was slow to go out, then I noticed both remained on.

    I didn't know one could do this on this age of vehicle, where do you plug it in. I will probably buy one off you, how do I pay you for it.......oh and those lock covers look a good thing especially up here on Isle of Skye!!!

    Thanks, I think I must be an air head as I can not see where the plug is on the link you sent. There is a page where there is no image available is that the page? if not could you please give me the page number.

    I would like to buy one of your readers and 3 door lock covers, please advise how I can pay via you paypal account.

    It is or should all be on the inside of the offside front wing, under the plastic cover with the winged head screws. .

    I will find you exact details as I need to know what socket is in the car, its too early I think for the 38 pin.

    Email sent with details

    OK thank you please undo that cover and see what socket is there. If the 38 pin it needs different leads and I must know that and I will provide the 38 pin pin outs

    I have removed a plastic cover near the coolant expansion tank is located I can only find right next to this tank is a round cabletied and lead sealed plastic cover which is approx a 2 pence diametre and is numbered 1 to 7 in a clockwise direction. it looks as if it has not been touched or opened since manufacture! I have looked all around the wing area and can not find anything resembling what you have described. Could you send a diagram please?
