how to remove memory module to basic 8 x way drivers seat
Hi
This will be work in progress as I edit and add to this thread
Objective , the removal of the drivers seatmemory module and fit an ordinary electric loom and 8 x way seat switch
Bit of history , had standard manual seats , my D3 is a base model , upgraded them to electric , passenger seat was plug and play
Drivers seat had memory ECU fitted , done bypass which allowed the few second power burst and seat to work
Had to disable memory ECU because it was causing a battery drain
Pics below are the current memory loom

Look at parts manual , the following are suppose to be drivers 8 x way looms
These are the looms, don’t know how they differ
All “ YML “ prefix letters
YML500373
500801
500871
500881
500891
In the mean time will carry will cut the memory loom open and trace each wire / colour / plug one by one
Hoping I’ll be able to adapt one of the looms, not worried about colours of the wires
Will update the thread when I make some progress , just hope this may help others later on

Before I touch the memory loom, this is the wiring memory module bypass adaption for the 2 x second power seat burst

I’d be interested to see how you get on with this mod. From memory I don’t think I did as much wire changing as you to get my seat to work with the two second bursts.

Hi
Indeed , I did do the mod to have the 2 x second burst , I’m now removing the memory module so that I can have constant power to the seat
Had to remove it because it was causing a 0.30 ma battery drain
Have now cut open the memory loom , so I can see what colour wires, pin terminals location , etc and how they join with each other
Can see this taking me a while, but find things like this interesting and indeed hope it helps others in the future if instead doing a memory bypass can get constant power to the seat
Well that’s the theory anyway
Also included the connector I need to each motor
Both White connectors ———-front seat base rise
Black ——- forwards / backwards
Green —- back seat recline
Grey ———- up/ down
Will have to double check those
Memory loom cut open
New non memory 8 x way switch

Also as a side note ref the black wire connector that sits underneath the seats
U can’t plug the wrong colour connector into it, they are all keyed differently

Hi
Wished to update this thread , can remove all the memory module and have a seat with constant power
After going through the loom etc today I now have a fully functioning seat , full 8 x way with no relays or memory module
Will take me a few days to alter some plugs , tidy the loom up properly , etc
Can then write it all out and how it’s done step by step

Thks pete
I do enjoy gluten for punishment
But must admit do enjoy doing projects like this
Just soldering up a couple of connectors , will then be done
Can do a write up then, longest bit was tracing all the wires / checking voltages
At least a normal loom and non memory switch can be fitted and get constant power to the seat ( without battery drain as well )
