Well i have checked out the k40 relay circut board as per Bazzles instructions. The three little soldered bits in the corner look fine no degredation at all, cant see any anywhere else either so have not touched teh soldering iron. I gave it a good blow and cleaned the 40A fuse and put it back in. I have tried re-starting it but cant get it to turn over.
My symptoms are exactly as described by Millerpim on the other thread ->

2000 SLK Ignition Troubles & Died at Light
For the past several months, when I turn the key in the ignition to start the car, nothing happens. No noise. No engagement. After 2 or 3 tries, which involve removing the key and reinserting it, it will engage and start. Yesterday, I ended up cranking the key 50 times or more before it finally started. Today, it fired right up, but after driving for 20 minutes and sitting at a light, it suddenly died while in drive. I put it in park and tried to start it. It did not start. After a couple minutes of fidgeting with the key and turning it over and over, it finally started. What could cause this?
In addition my problem seems to be that if i turn the key to position 2, the fan comes on immediately (even on a cold start) and keeps spinning at high speed nothing else happens if i try and turn to ignition no sound of it trying to turn over or anything.
Prab again -------> So having had a look at the circuit board and it looking ok. Is there anything else anyone can reccomend. I have lost faith with the dealers and just want to get her up and running again. Sicne i took the module out she has not started again but that was only 30 mins ago will try her again later.
HELP! Anyone? Much appreciated.
