Revised B4 MFA conversion article

Rammstein · March 1st, 2005, 17:11

You're my hero Chris!!!!!!!!

I also wanted to get the original tach back, bought another cluster to do the swap...

I'll read your revised DIY with great interest!

Awesome!!!

By the way, you refer to Palo Alto Speedometers...any idea if they would do a cluster conversion?

This is EXACTLY what I was hoping to do! Now that this writeup is out, all I need is to source the remaining parts! I have a GLX cluster 3AO 919 035 H, I forgot what year GLX it came out of. The p/n is different from the discontinued one you mention, however it does have the MFA and is buit by Motometer. Should I be concerned?

Thanks

Thank you Chris!

Unfortuately, no they won't.

It shouldn't be a problem. It may an automatic cluster.

Thanks. It does not have the gear selection window. I'm looking forward to picking up the remaining parts.

Any A3/B4 cluster can be reprogrammed for country code and # of cylinders, I did this with MFA on my A3 Jetta using VR6 cluster, its just a matter of small change in the software, its pretty simple.

Could you elaborate please?

All data like country code is implemented in the software in HEX code, for example when you read the chip and look in to the code, US is 02 CAN is 20 UK is 49 and EU is 48, this code is related to the clock (12/24) and service reminder (only EU and UK have this when recoded) then if you look further you will notice number of cylinders (4 cyl is 80, when 6 cyl is C0, and the similar thing with impulse # 6056 is for VR6 in hex is 17A8)so if you compare data from TDI cluster and VR6 MFA you will notice how its done.

Could you elaborate more please? Read the chip?

Chris Bell · March 4th, 2005, 07:32

Do you need a HEX-COM interface to read the cluster? A KEY-COM interface won't read it

Inside this cluster is chip 93C56, to read this programmer is needed, VAG won’t work

I am confused why a pulse frequency adaptor would be necessary for a GLS cluster as it also has four cylinders. I assume because of different spacing on the tach face?
