VW T5 disable tachograph

**vwaraf** · 28th February, 2021, 04:18 PM

Hi
I would like to ask for help in removing the digital tachograph from the dashboard.
I can not change the adaptation in VCDS because the tachograph is damaged.
Thank you in advance.

I know you shouldn't. Just disconnect the tacho, if you say it is defective, so that it does not make other defects.

Hi!

Could you help me? I have a problem with instrument cluster (7H0920861B) from VW T5.

The instrument cluster had been temporarily connected to another car which has tachograph. When cluster was set back to original car, the cluster lost the speed etc. Now 33 has been changed to zero but speedometer does not work. How can I fix the problem?

Thank you in advance.

Hi Guys

I have the same issue as those in here. The cluster I have just fitted was previously a tacho cluster (which I believe is disabled) but the speedometer, odometer and fuel gauge do not work as I think its expecting the tacho to be connected still

Dump is attached (removed) - could someone kindly ensure the tacho is off, and sort the speedo/fuel gauge out please

thanks!

Hello !

Thank you very much !

First time you need to remove the tachograph from the instrument cluster. With VCDS, adaptation, channel 33.
Then, if the speedometer and fuel indicator will not work, we can modify in eeprom to take the values from the CAN, or you can make the physical modification, on the wires to "pass over" the tachograph.

Hello !

Thank you very much for the time.

My problem is that i cant disable it with VCDS i always have an error. Also i dont have the tachograph installed physically but a Little box that emulate it i think with reference : DT Replace Module

(https://shop.fahrtschreiberdienst.de...dul-vw-t5.html)

Thanks

Edit : After unplugging this little box, i had a big T on my instrument cluster, so now i can disable the tachograph with VCDS. After that speedomoter is not working + the fuel jauge is going crazy

If someone have a solution for that using values from the CAN, please let me know
