UK-POLOS.NET - THE VW Polo Forum

Hi guys,

I want to share my experience in upgrading Midline to MFA+ Instrument Cluster.

It's not a secret that GTI IC really difficult to find.
(At an adequate price)
For a while I was monitoring local breakers and allegro.pl but without success...
So I decided to buy compatible MFA+ from Skoda Rapid or Seat Toledo!
Cluster from Toledo by my mind match better to Polo because of red needles, so I found good offer on Allegro and ordered it!



But this IC housing is different from Polo IC, so you can't directly fit it...

There are two ways to solve this:
1.Use housing from old IC
2.Figure out something different

I really like how looks like Polo 6C IC, so I decided to adapt 6C body to Toledos IC
Ordered it from Allegro as well.

( 6C ic's are really cheap! I've payed €25)


Few weeks later I got both IC's and started my project!
I divided this project for two stages:


STAGE ONE - Electronic adaptation

For this purpose I borrowed correct tool from one very good guy!
So it was like piece a cake, read out my IMMO Data through OBD and write it to new IC on the bench!

Keys learned!

After that necessary to change some Bytes in EEPROM:

• Welcome picture from Seat to VW
  --- Need to change Byte 02F3 to 00

• Tank size from 55l to 45l
  --- Need to change Byte 0065 to 83

• Car picture to hatchback
  --- I've used Ki Helper. https://www.drive2.ru/b/3087799/

STAGE TWO - Physical adaptation


We need three left parts (I took Seat original back cover)

Here I spent a lot of time...
Because 6c IC have different construction and it's not possible just swap housing,
You need to cut, melt, grind plastic and after solder some pieces to correct place...



After I finally adjusted it I saw that there is some uncovered space between scale disc and housing:



I have solved this problem with chrome rings from Seat dash



There are some interesting pictographs like side assist and lane assist:




And the final result:




I am really satisfied with result!

I think it will be very useful to clarify a but closer what exactly you used for stage one, the transfer of the immo data.
Apart from that, good post.

Thanks!
For Stage one i have used this device: http://supervag.com/

cool mod! ive been looking into this as well. but:

1) how do u exactly solve the gap between the dial and cover? using the rings from seat? i dont see how.

2) moving from the old design to this new design, how the light sensor performance now? will it be correct or it will always light up the cluster as the light sensor thot its darker inside due to new design which limits the brightness inside?

Here are some pictures for compare:

As you can see lights sensor is not covered, so it works like it should..

thanks my friend!

and the icon availability for lane assist and side assist/park pilot seems interesting. so iichell, is this going to work properly as solution for side assist?

I don't know about other devices!
I suppose there are a lot of devices wich could make dashboard swap.
Most widespread: AVDI VVDI FVDI,
but SuperVag is more simple for this purpose!

Seat dials look much better than POLO

Part number for the petrol version: 6JA920840D and diesel 6JA920840A.
I have the XHORSE MM-007 scanner myself for learning keys, but I don't know if it's able to learn keys on a used cluster, without having a working key.

Nice mod! (Dials with sports numbering )

In my humble opinion you should be precise with these little things ...

You would already have the software you want if it would depend on me... you know I like to share, but I always respect the information provided by others.

Thank you, ciclo

Odometer was adjusted automatically, so i decided to leave it like that

Hope i will find that firmware one day!

It will surely happen, would you try it with a 0805?

Sure, if i will find flash file copatible with my hardware!
