Warning light - it signals an unidentified problem with your car; it usually requires the car to be serviced.

Test battery charge, jump the battery to start and check battery charge, sound like a alternator or voltageregulator wrong there.

Yes i have had this before its because you have connected the wires wrong and used the feed for the lights ,cannot tell you the colours as i cannot remember and iam colour blind but this is whats wrong your 12v switchable feed what you think is the feed from the ignition is actually your illumination feed for the radio ,if in doubt run a new wire from the ignition switch direct to teh radiop this will cure it i promise ,Sorry i cannot tell, you what wire is what but when the reds and greens all look the same ?? you understand my plight but this is your problem i do know for sure as done two motors like this in the last few years .

The radio SERIAL NUMBER is required for a code First remove theradio from the dashboard. Then post the radiomake+model plus all the letters+numbers on any labels,barcodes or stamped inthe metal casing.
This information canthen be used to see if a code can be calculated

Hi and welcome!

As a first course of action I strongly suggest that you check the transmission fluid. If it's burnt please have it replaced. If the fluid looks fine then the problem will surely be on the torque converter. The torque converter controls the shifting of the car. Once replaced, a smooth ride and shifting will be noticeable.

Hope this helps and thank you for using FixYa! Have a good one!

I would calla dealer and ask him. A SLK-Class is a good car so hopefully there is not a big problem.

Hi Joe here, The problem with your a/c is a sensor. Most likely the pressure sensor. You need to have the vehicle scanned to find out which sensor it is. 

need more info-possible bas diaphragm switch gone bad.does the fault occur as soon as you turn on the car or as soon as you step on the brake pedal??
