Attached is a little PDF guide with lots of pictures. Enjoy...

And, if someone knows why my trailer monitor lights now flash with the hazard lights - please let me know! :)

Cheers,
Nick

hmm, can't get the pdf to upload at the minute... I'll try again in a bit...

NDC – 2003 Ford Galaxy Indicator Relay Replacement

2003 Ford Galaxy 1.9 tdi 115bhp – MFU (multi functional unit) indicator relay replacement

My left hand indicator was sticking on intermittently. After looking for the relay to replace, I found it was soldered to the MFU board!?!? I decided to replace the soldered unit with a couple of relays wired outside of the box. Nothing to lose if it didn’t work, as it needed fixing - ebay seemed to have a few MFU boxes for around the £60 mark. I imagine a new unit is quite a lot more!...
Hope it helps someone.

I haven’t checked all my notes, so please treat this as more of a 'guide'... :) It is also probably worth having a read up on relays to make sure you wire it all up correctly. You should be able to test the relays by using a 12v supply and a multimeter to check for correct switching.

Enjoy!

NOTES:
  • De-soldering the indicator relay is tricky. I am sure there are proper tools to do it properly. I managed to ease it out by working from the top and heating the pins from underneath whilst levering the unit. Took about 5mins to go round and ease it out. I also found that trimming off the legs from underneath gave less metal for the solder to stick to and helped release the pins.
  • Make sure you drill a hole for the cable to exit the box at the top of the unit – as per the last picture. Otherwise you might have difficulty getting the fuse box back in!
  • The only issue I had after putting it altogether was that the trailer light monitor flashes on the dash (assume if you had a buzzer this would also buzz) when hazards are flashing (without trailer lights connected). Seems to be fine with left/right indicators though. I am guessing that the new setup is drawing a bit more current when both relays are working causing the trailer light monitor to think it is driving some more bulbs?!?!

2003 Ford Galaxy 1.9tdi 130bhp ASZ Engine code  Replacement of the MFU or Fuse box circuit board.......

 

If you can find one of these MFU's or fuse boards for cheap then just follows Nicks photos and you should be ok. You need to be a little bit mechanically confident, not really for a novice.

My problem was with my left indicator, just did not flash at all only a faster than usual intermitent clicking. Fords design of the indicator relay being soldered straight onto the circuit board was totally mind boggling. Most other cars have a simple pull out and push in relay. I can only guess it was so that people would only go back to a Fords dealer or one of their franchises etc and spend big money. I asked a ford dealer how much one these boards were and was quoted £989 plus VAT! So maybe £1500 or so with labour.....! LOL

 

Anyway I checked on ebay and found they were around the £50 - £100 mark for a used fuse box, not bad. Also on ebay a guy was selling the actual relay only for £50 but that requires you to be a pretty compitent solderer as the relay is only about an inch or less in length and has 8 points which need soldering.

 

However i couldn't wait for postage etc from ebay and couldnt risk having a dodgy board sent to me etc as my MOT was due in a couple of days. So I called up my spares scrap yard Brancroft Autos who are based in London Edmonton. They have more or less everything 95% of the time. They said a 2003 Ford Galaxy just turned up in the yard and they were taking it apart and I could have the fuse box for £40.

 

I picked up the fuse box and then fitted it all in and tried the indicator and yay it all worked. However have to remind anyone who changes the MFU that your remote central locking coding is on that board. So basically I had to reprogamme my key fob which took not even 5mins. There are many threads on this forum which will tell you how to do this and you only need the 1 key.
