Here is the problem - I've got my Vag-com to work. I have the Ebay cable and a full working version of 311.2 from ross-tech. With the car off and the ingnition turned on to accesories I can read everything - any module and find all fault codes(if present). Today I went down to do some block measuing and I can do all that I said above but when I start my car I cannot do anything - it thinks forever and then gives me an error message that says: "session unreliable" "too many communication errors to continue" Any Idea's on what the problem is besides my having a ebay cable?

 

You shouldnt be communicating with or have any controllers open while starting the car. Its best to close all controllers before starting the engine. Thats all i can think of. So if you want to measure blocks in the engine controller, make sure the engine controller is closed, start the engine, and then go into the controller and measuring blocks.

 

I don't think I had anything open when I did start the car - but I will go try again - thanks

 

ok - that didn't work - tried to start car and then start the vag-com program and controler and that didn't work - tried to start the program then start the car then go into the conroler and that didn't work. still get same error message - another thing is that before it does give me the error message the code G71M=-1 then -2 then -3 is displayed in the upper left hand corner - I googled the code and all I got was one report of this code in the UK with no suggested fix and all the rest were in Russian[:@] any more idea's I tried my shareware version of 409 and that did the same thing.

 

I thought you can not do logging with the ebay cable? Only the real Ross-tech cable did logging.

Thats just comparind shareware VS fully registered vag com software. Any OBDII cable should work. I know of people with the ebay cable that have done logs, so i dont think thats the problem.

 

I posted this on audi-sport.net and a guy from ross-tech said
But my only responce to that is the cable works the rest of the time - just not when the car is running.

 

Oh, didn't see it was the "full version"

How about uninstalling & reinstalling the cable drivers, & maybe Vag-com. You never know when something gets messed up in windows.

 

Yeah I have an ebay cable and I can run logs just fine.

 

ok - looks like I'll start from the begining YEAH WOOPIE[:'(]

hope this works

alias747- what is your starting sequence when you are going to run a log - ie - start vag then start car then open controller. just to make sure I 'm doin this right
