Anyone know if we can reprogram the central gateway with STAR or do I have to go to the dealership. Faults in my car were found to be caused by a bad central gateway. I have a used one on my shelf and my MBZ mech told me he would reprogram the gateway to my car. I test drove the car tonight and I have no control over air suspension, distronic (speedtronic error) and it seems as though my original functions on the car are not working properly. I took a look at the car I took the GCW from and it didn't have any of those functions (no air susp, no disctronic). I am wondering if my mechanic knew wtf he was doing and if he reprogrammed it correctly. I just want to know if I can do this myself with STAR, should I take it to the stealership, or can I send it to one of you guys to reprogram it. Kinda lost on what to do.

 

you can do it via DAS and it has to be installed

 

Yes I understood that portion. But I am not sure if my mechanic knows/knew what he was doing when he 'reprogrammed' it to my car. Again my basic functions like air suspension and distronic are lost, plus I have no communication to my transmission computer and shifter. I am wondering if maybe there was no way to grab the old info from the original gateway (since it went bad) and I am unable to retain my original functions. Again the used gateway I put into the car does not have air suspension,distronic,parktronic, and I do not have those functions in my car right now.

Let me rephrase my question, if the original module went bad and he can not get any of the old data off the module, do I need to take it to a dealership and have them reprogram it or will the car adapt to it?

 

DAS will guide you through the process of reading the old CGW and coding the new one.

 

I know I am asking "what if" questions, but what if he can not read/access the original gateway. Would the stealership be able to get the factory settings programmed correctly?

 

What was your mech originally trying to do when this started?

 

My central gateway took a ****. Started tripping out all my electronics. He pinpointed it to a faulty module. I'm not trying to reprogram miles or anything like that. I just want my functions back .

 

obviously.

I dont know if you have ever used STAR but if you have then the CGW screen will show all the options for the W211 chassis all you would have to do is select present / not present and recode the module.

 

Lol, My thinking wasn't even headed in that direction. I ask because I'm wondering if you've tried something as simple as disconnecting both batteries for a few minutes?

When my E55 was delivered it had a dead battery in one of the key fobs. The truck driver thought it was a dead car battery and tried to jump the SBC battery. I got there just in time to see what he had done but not stop him. Anyways, the car gave me all the same symptoms, faults, and error codes you're getting. I connected Star and erased all the codes then disconnected both batteries for a few minutes. Everything was worked perfectly after.

 

well then he must have not done a great job. I'm shopping around for a star for a Christmas present for myself. I think I saw you sell them.

Yes I believe you mentioned this in my previous thread with all my codes and errors. Tried and failed. I cleared codes through all modules I could access with my snap-on modis. Again they later pinpointed it to a faulty GGW module. :|

 

If you cannot read the old CGW. Then you should get a copy of your VMI and it can be coded properly. I would say that if you did not have this available at the time of coding. You can look at the car to see if certain options are fitted. If your "mechanic" gave you your vehicle back with all of these problems still occurring. I would find a new mechanic.

 

If you can read the old CGW, that is the best. If not you need to find settings from someone who has similar options and go through one by one to check they are set correctly. The dealership can also restore to default settings if necessary.

None of this is possible without DAS. I swapped out my rear SAM and encountered weird battery low issues but setting coding appropriately fixed my issues. Some of the settings are obvious, some are less so. I needed Developer DAS to set mine up right.
