  1. AC Problem: DTC B1057, fault in CAN communication with RCP

    R230 SL-Class
    OK, it is looking/feeling better after adding some R-134a freon. Sorry for the delay in responding, but other house hold items stopped me from working on the Benz. I used a AC Gauge Set and added freon to my system. Took extra precaution not to let out freon from the system and not to let in...

    R230 SL-Class
    46 degree C = 115 degree F. So, the day I was working on the car it was 95 degree F. I have notice when I get in the car after it is sitting in the hot sun the temperature reading in the dash display will read higher. That is very hot! Where is the ambient sensor located? Might need to...

  4. ABC Valve Block Removal

    Glad to hear the job was made easier. After I bought the rebuild kit and tools, I did not rebuild the Valve Block because my care stopped sinking down overnight. I am not sure why?

    W211 E-Class
    I would spend $500 for a unit if I knew that it would program my vin into the airbag module. I really don't like the idea of selling the car with any known problems. Any recommendations for vendors or just go for the choices at the start of this post? I bought the used SRS module from Ebay...

    W211 E-Class
    Yes, you both have encouraged me to keep going. I am ready and willing to dive into the programming, but the cost for one of these devices (ie. XENTRY) with programmabilty are in the $1500 - $2000 price range plus lisencing fees. This is my only Mercedes that we will soon be selling, so it is...

    W211 E-Class
    So the local Mercedes dealer service dept will not program my vin into the used SRS module I install on my 2005 SL500. Those of you that have a SDS with programming, can I send you my module to program my vin? Do you need the car to do it? Is anybody near Santa Fe NM that I can drive it to...

    W211 E-Class
    I have reviewed this post and did not see anything about the Star C4 being able to reprogram and or coding? I need to program my vin into a used SRS module I installed on my 2005 SL500, R230. If it will do this, what is the preferred vendors name on AliExpress? Thanks, Patrick
