Title: audi S4 B5 instrument cluster rescale to 300 km/h DEF ERROR Post by: ManiacuV6 on September 26, 2017, 12:22:08 PM I tried to rescale an UK Instrument cluster to 300km/h scale like the rs4 but I get the DEF error. I need help from someone to correct the checksum .
Thanks for your help @ Title: Re: audi S4 B5 instrument cluster rescale to 300 km/h DEF ERROR Post by: _nameless on September 26, 2017, 09:24:55 PM I tried to rescale an UK Instrument cluster to 300km/h scale like the rs4 but I get the DEF error. I need help from someone to correct the checksum . go to recode and click do it, when you click do it it updates cks should be ok Thanks for your help @ Title: Re: Post by: macxxx on September 26, 2017, 11:55:05 PM Marty it doesn't work with audi 920 clusters.
ManiacuV6 attacht the dump , I think I can help you Title: Re: audi S4 B5 instrument cluster rescale to 310 km/h DEF ERROR Post by: ManiacuV6 on October 12, 2017, 12:13:04 PM Thanks for help Marty@
Recode won't do it. I've already tried. :( Title: Re: audi S4 B5 instrument cluster rescale to 300 km/h DEF ERROR Post by: nyet on October 12, 2017, 12:50:28 PM Having been through this once on an S4 cluster, you may need to desolder the eeprom and flash it with a programmer, or in-circuit flash it with a clip.
Title: Re: audi S4 B5 instrument cluster rescale to 300 km/h DEF ERROR Post by: macxxx on October 12, 2017, 12:55:32 PM nyet the problem is diffrent value of checksum in rs4 speedo map , it's diffrent than in UK or Euro cluster. I have made 2 clusters with rs4 or rs6 scales using PCB froma normal B5 cluster.
Maniacuv6 where are you from? Post photo what type of scale you want to use. Is the attached dump original or modified? Title: Re: audi S4 B5 instrument cluster rescale to 300 km/h DEF ERROR Post by: ManiacuV6 on October 12, 2017, 09:49:06 PM the speedo scale is already done based on a RS4 file. All I need is the checksum to be right.
In 20 miuntes I'll post a pic of speedo . Title: Re: audi S4 B5 instrument cluster rescale to 300 km/h DEF ERROR Post by: ManiacuV6 on October 13, 2017, 12:31:46 AM Pic with the cluster
Title: Re: Post by: macxxx on October 14, 2017, 11:24:43 AM But i need the original dump
Where did you buy these gauge scales? Title: Re: audi S4 B5 instrument cluster rescale to 300 km/h DEF ERROR Post by: ManiacuV6 on October 14, 2017, 11:40:09 AM I post the original dump.
I purchased form a german site. I need to search to tell you exacly which website. Thanks! Title: Re: audi S4 B5 instrument cluster rescale to 300 km/h DEF ERROR Post by: macxxx on October 14, 2017, 11:37:23 PM try this dump
removed attachment becase it was crap :P Title: Re: audi S4 B5 instrument cluster rescale to 300 km/h DEF ERROR Post by: ManiacuV6 on October 15, 2017, 01:42:29 PM Tomorrow I will test and reply. Thanks@
Title: Re: audi S4 B5 instrument cluster rescale to 300 km/h DEF ERROR Post by: ManiacuV6 on October 15, 2017, 10:47:05 PM Same "def" error
Title: Re: Post by: macxxx on October 15, 2017, 11:37:31 PM Ok I will Give IT another try
Title: Re: audi S4 B5 instrument cluster rescale to 300 km/h DEF ERROR Post by: macxxx on October 16, 2017, 08:43:31 AM this one will work , tested on a cluster on bench
Title: Re: audi S4 B5 instrument cluster rescale to 300 km/h DEF ERROR Post by: ManiacuV6 on October 17, 2017, 06:33:59 AM It works! Thanks !
Title: Re: audi S4 B5 instrument cluster rescale to 300 km/h DEF ERROR Post by: ViloRicsi on November 25, 2017, 03:29:41 PM Hi! I hope i can get some help too. I have similar problem.
I swapped my B3 coupe quattro to 1.8t AEB , and I'm using an A6 c5 1.8t cluster. I have to mod the speedo and fuel gauge. I find a write up with the gauge scale bit locations so i tried to calibrate speedo first. It worked out good now my speedo shows exact speeds, but now i have 'def' on the trip display... I tried to find out how i can corrigate the checksum but find no info about it. Any help would be great. I post the original and modded dump too, maybe somebody can help to find checksum. cluster is: 4b0 920 980 H Title: Re: audi S4 B5 instrument cluster rescale to 300 km/h DEF ERROR Post by: macxxx on November 26, 2017, 01:25:56 PM Do you want the 980H ( GB cluster with mph? ) To fit eu scales 260 kmh?
Title: Re: audi S4 B5 instrument cluster rescale to 300 km/h DEF ERROR Post by: ViloRicsi on November 26, 2017, 01:35:40 PM Do you want the 980H ( GB cluster with mph? ) To fit eu scales 260 kmh? Yes i already fitted eu scale (km/h 260) from a similar tdi cluster, and recoded the IC for Eu coding (00144). From other topics and posts I guessing the speedo map checksum bit is 0xb2, but I have no idea how to correct it or is this the only cheksum bit... Mod is not just about to fit the eu scale, but correction for the different signal from the gearbox due to the AEB swapped to the original 01A quattro gearbox... Maybe I have to calculate and change K value too? Title: Re: audi S4 B5 instrument cluster rescale to 300 km/h DEF ERROR Post by: macxxx on November 26, 2017, 03:50:32 PM this should work , test it and check if its ok
Title: Re: audi S4 B5 instrument cluster rescale to 300 km/h DEF ERROR Post by: ViloRicsi on November 27, 2017, 05:11:22 AM this should work , test it and check if its ok It's perfect!! Thank you very much! As I eyeballed to the gear and rpm the speedo shows proper speeds, tonight i will check with gps. May you tell me how you did it? I see you changed both axis of speedo map , but the other bits? all for the checksum? Title: Re: audi S4 B5 instrument cluster rescale to 300 km/h DEF ERROR Post by: macxxx on November 27, 2017, 09:43:08 AM Find a eu cluster dump and compare what did I change ;) you should see that adresses beetween the 0b2 and Speedo map are the same in almost all similar clusters
