Title: Cluster swap S4 B7 cluster to A4 B6 Post by: BlackT on May 07, 2019, 01:43:11 PM I have audi A4 B6 1.8T 2003 with RB8 cluster. Now i want to put in S4 B7 2007 cluster. As I can see on internet I must be really cerful with this clusters beacuse they are so easy to brick.
I put S4 in my car and it show 'SAFE' at odometer and as I espected car start and shut down after second. I will do immo off in ECU, but second problem I have is warrning for max oil level. I must get rid of that beacuse is realy anoing. Maybe some resistor on oil level wire?

I made a similar mod for somebody - changed a a4 b7 2.0tdi cluster to a s4 b6 cluster ( the a4 b7 was after a swap to 2.7bit engine and added quattro ) Looks like a s4 cluster but the pcb is from a4 b7 - everything works nicely Title: Re: Cluster swap S4 B7 cluster to A4 B6 Post by: BlackT on May 07, 2019, 02:04:09 PM I have same plan to do it at the end. As i can see there is no other solution.
How hard is to edit RB8 epprom. What tools do I need? Title: Re: Cluster swap S4 B7 cluster to A4 B6 Post by: macxxx on May 07, 2019, 02:12:09 PM Scales are outside crypted region so almost no risk , as i had the pcb on table i desoldered eprom and changed it with a programeer , as i remember its a 24c02

Any instructions where epprom hold data for scales? My S4 cluster is from 2004 is it posible that is RB4 with immo III? Title: Re: Cluster swap S4 B7 cluster to A4 B6 Post by: macxxx on May 08, 2019, 07:37:59 AM A4 b6 clusters are rb4 immo3
Title: Re: Cluster swap S4 B7 cluster to A4 B6 Post by: BlackT on May 08, 2019, 07:52:53 AM But on my car is RB8 cluster
Title: Re: Cluster swap S4 B7 cluster to A4 B6 Post by: macxxx on May 08, 2019, 07:54:52 AM Someone told me that at the end of production there were some rb8 clusters - i guess your situation fits it
Title: Re: Cluster swap S4 B7 cluster to A4 B6 Post by: BlackT on May 08, 2019, 08:17:47 AM Maybe, or maybe someono put in RB8 cluster. I don't know the history of car
Can you see from that vcds sccrenshot is that S4 cluster RRB8 or RB4 Title: Re: Cluster swap S4 B7 cluster to A4 B6 Post by: macxxx on May 08, 2019, 08:21:52 AM Wfs4 means immo4 it has to be rb8 , what the number of yours cluster?
Title: Re: Cluster swap S4 B7 cluster to A4 B6 Post by: BlackT on May 09, 2019, 09:19:38 AM This is cluster curently in my car
Title: Re: Cluster swap S4 B7 cluster to A4 B6 Post by: macxxx on May 09, 2019, 09:21:07 AM X in number means its a cluster from dealer so it had to be changed sometime in car history
Did you get PM? Title: Re: Cluster swap S4 B7 cluster to A4 B6 Post by: BlackT on May 09, 2019, 12:09:53 PM There is one more problem, i have oil level warning.
Is there diference betwen B6 and B7 oil sensor? https://youtu.be/DCBN2u3dNTc Title: Re: Cluster swap S4 B7 cluster to A4 B6 Post by: macxxx on May 09, 2019, 12:18:42 PM maybe some coding or adaptation? the sensor sends a digital signal to cluster , maybe the cluster thinks that it nas a v8 under hood and that's why oil Is max - I will check in etka if the numbers are different
the other thing is as I remember - b7 clusters recieves coolant temp. by CAN or am I wrong? Title: Re: Cluster swap S4 B7 cluster to A4 B6 Post by: macxxx on May 09, 2019, 01:05:13 PM the oil sensor seems to have the same number , different part numer is in 2.0tfsi and 3.2FSI
Title: Re: Cluster swap S4 B7 cluster to A4 B6 Post by: BlackT on May 09, 2019, 01:42:22 PM Yes i see that too ??? maybe something in cluster is not right? Are you sure that there is digital signal for oil level? schouldun't be something like analog 0-5 V?
For coolant temp i must do some research Title: Re: Cluster swap S4 B7 cluster to A4 B6 Post by: macxxx on May 09, 2019, 01:56:31 PM maybe I wasn't precise with the digital signal , I wanted to say its not an simple resistance ;)
Code: The TOG by Hella uses a simple pulse sequence with the time between two pulses and the length of the pulses representing oil temperature and oil condition/quality. As TinyTOG focuses on engines before 2000 (without long life service) only the coding of the oil temperature was analyzed. It turned out that time between the first and the second pulse together with the length of the second pulse represent the oil temperature. The first pulse is constantly 20ms long. The delay between two cycles must be at least 250ms long. |
