Retro fitting footwell lights from http://www.aliexpress.com/fm-store/315636

I can't remember sorry... I think there may have been a single Bit to enable the CECM,
but it is all labelled in VCDS so should be easy.

In 2008 Tig I have old Mk5 CECM + CCM, no BCM, looks like this, part number 3C0 937 049 AH (30-byte "MID" unit)

I bring up this old thread with an update on the topic of rear footwell lights in TIGUAN, which are not present not even as an option AFAIK:

FRONT footwell lights

Bold sport kit with LED upgrade built-in (find on bold-sport)

• The dash already has cutouts for the OEM lights to just clip in (for driver it's near the OBD port).
• The kit comes with the wiring, you just need to push the pin into the right place in the BCM connector.
• For 2008 mk5 based Tig it was connector B pin 7, for a newer mk6 based Tig it is connector B pin 50 - the bold sport website shows all the details.
• The BCM is located above the fusebox, under the driver's side dash on a RHD vehicle.
• Dimming footwell lights from the instrument cluster menu works great.

REAR footwell lights

• The rear footwells (under the front seats) don't have spaces for the OEM light units
• These sturdy aluminium LED bar lights from Jaycar Australia fit perfectly and can be screwed in to the seat bottom with small screws - there is a plastic area just at the back of the seat which angles the LED lights just right, and is easy to screw into. Or use cable ties if you don't feel like making small screw holes
• I ran the wiring together with the loom going to the seat (so it doesn't get pinched when you slide the seat), then under the carpet to travel along the door sills. Then connected to the front footwell lights wiring loom from boldsport.
  
• The door sill trims just clip out (see OEM RVC install, same location). Note for the passenger side, you need to unclip the trunk release button which is easy when you know how: You need to undo and remove the small clip which sits under the handle, towards the front of the car.

Aluminium LED bar light from Jaycar, part number ST3918. Cost $40 for two.
Comes with wiring and screws to attach to the seat.

Hello YellowLemon!

Very interesting mod, congratulations!

Can you take a picture to help me locate the BCM? How difficult is to do this retrofit? I'm only interested on front footwell light...

Cheers.

In RHD Tiguan in Australia, in 2008 year, CECM is just above the fuse box, which is above the driver side pedals. HOWEVER on LHD vehicle it may be on drivers side, or on passenger side behind glovebox (maybe have to remove glove box) - sorry I don't know.



From the front it looks like a bunch of relays attached to a black box:


To insert the wire into connector, you have to access the cables from the bottom, it looks like this:


Not difficult, just very "tricky", have to climb under dash upside down to access connector Fronts only took me 30 mins - 1 hour maximum.

On mk6 electronics BCM (new name for CECM+CCM) looks like this, with only 3 connectors, much easier to do!

Thanks for the detailed photos!

Even on LHD the fusebox is on driver side

On a Tiguan MY2010 what should I found: BCM or CECM+CCM? Can I know it from a VAG scan or I need to check under the dash?

Cheers.

On MY2010 you will have BCM =three big connectors. It is easier to do on 2010+ than on MY 2008-2009
