Title: IMMO fixed now O2s No Activity- Related? Post by: b4A4nowA6 on January 18, 2016, 07:50:45 PM As the title says. I have a 2003 a6 ME7.1.1 and it has been down for a little bit. Finally got it all back together (minus the slave cylinder) and I could start it up and idle just fine. Then one day it would start and die right away. Immo code all of a sudden. had to try different tools from ArgDub and another member that made a program in order to get the info off my EEPROM and I was able to get my car started again and driving.
Now the problem is that I keep getting these Errors. -Missing message from Cluster -B1S1 no activity -B2S2 no Activity I think I get another code as well for each primary o2 sensor. So I changed them out and thought would work (even though I thought it to be weird that both would go out at the same time) and NO luck. When I take logs, it does not appear that my O2's are not working. Could it be related from the flashing of the Eeprom.? All I want is to be able to pass smog and happily drive my car again. If I have to send out my clust and ECu to someone I will. Title: Re: IMMO fixed now O2s No Activity- Related? Post by: k0mpresd on January 19, 2016, 01:37:53 AM e2p file is wrong. should be 1kb i believe. yours is only 512 bytes.
thats a 5p e2p i think, not 95040. someone correct me if I'm mistaken. its late. lol. Title: Re: IMMO fixed now O2s No Activity- Related? Post by: ddillenger on January 19, 2016, 02:11:23 AM You are correct, but the 2nd half is just FF FF.

I may have uploaded the wrong bin but I think that was the one from my EEPROM. And no I do not have a spare ECU, looks like I need to hit up eBay. I will update shortly.
