06-07 Mercedes-Benz have faulty ecm’s. The other reason a fan will run is lack or communication through the CAN data bus. • 06-07 E C CLK ML GL R SL have bad ECM’s!! • Hello fellow Mercedes-Benz friends. In this video I show you how diagnosis can lie to you and confuse you and how to always VERIFY the fault before repairing anything or buying parts. • I deal with this issue all the time and 99% of the time the engine modules are faulty. But it is no fun to make a video telling you that. So instead I showed how the diagnosis should have went down. Now what I did on my own meathead time was try and save the customer some money by swapping EEPROMS. I am NOT an electrical engineer , I am NOT good with small circuit board repairs and you will see haha. • I was lucky enough to swap the EEPROM from the customers ECM to a used ECM and then to another used ECM and back to the original ECM and it still worked!!!! • In the end it was more cost effective to find a used ecm, send both out to a mobile mechanic with the software to swap Drive Authorization Data and VINs in the modules and plug and play. • I did try Mercedesecm.com and they jacked me around for 1 month. Luckily they refunded the 800 they charged me for a reconditioned ecm that never came or was sent. • • if you would kindly donate to my channel • https://www.Paypal.me/Benztech • please leave a like, hit subscribe. • More videos to come! • Lou
