Hi
My car is D9 executive SEMI mux , it has:
Electric, heater memory seats
Sunroof
Folding mirror
Amplifier
Reverse sensor
Cruise control
Deadlocking
Alarm function with interior sensors
So i want to convert it to full mux, which i know i must get :
Ecu, bsi, fuse box
Com2000
So please what else do i need to change?

Re: Semi mux to full mix conversion
I would expect there to be big differences in the wiring looms. For example there are only a few connections and the data bus to a comm2000 versus the individual wiring for all the stalks on earlier cars. Engine loom will differ too e.g. 1 coolant temp sensor vs 3 and so on.
2002 HDi 2.2 Exec Estate, (2008-12) (wonderful)
2003 HDi 2.2 6-speed Exec Estate (2012-19) (also a gem)
2009 Citroen C5 2.0 HDi VTR+ Estate (godawful heap)
2008 BMW E91 330i touring (great fun - murdered by a reversing SUV)
2007 BMW E91 325i touring (slower smoother quieter)

Re: Semi mux to full mix conversion
May I ask why you want to convert it?
It's regarded that the semi mux is the better option as the wiring, albeit a little basic, is more reliable and has less hissy fits ..
As Doggy says, it's a completely different generation, the Comms being a good example as this has a different steering wheel, airbag, airbag triggers, stereo controls, cruise control is fed from a different source, this involves extra wiring from the pedals ( I think )...
This is just one component that's different for a semi/mux - imagine when you add heated memory seats, central locking, windscreen, extra fuseboxes and engine sensors...
You would be moving from a car with individual wiring loom sections to a car with a 'one connection for all gadgets' philosophy, I'm sure it's possible given time, money and a donor car alongside - and this is solely my own opinion, but in my eyes is a big task for essentially nicer indicator stalks.....

Re: Semi mux to full mix conversion
Ok. So both dashboard wires and engine wires must be changedDoggy wrote: ↑Sun Jun 05, 2022 10:56 pm I would expect there to be big differences in the wiring looms.

Re: Semi mux to full mix conversion
I want it because i realized it's simpler.. Most importantly some functions were only found in full mux.. Such as auto doors lock, compatibility with android system due to CANBUS technology which interfaces with the car details and functionality , auto light, running day light, few wires, etcGingerMagic wrote: ↑Sun Jun 05, 2022 11:42 pm May I ask why you want to convert it?

I dunno other advantages

Re: Semi mux to full mix conversion
Remove radiator cap, install full-mux car, replace radiator cap
There would be so much to replace you'd be better off getting a donor car, putting your interior in that and binning yours.
I hear auto door locks are great for wearing locks out, they go one at a time so you won't know until none of them work.

Please was there any advantage of full mux over semi mux based on performance and fuel efficiency?
Is there any way to inculcate auto lock and auto light into semi mux without converting it to full mux? ,

Re: Semi mux to full mix conversion
Nope. None of it affected the powertrain.
Umm, I'm guessing these weren't options on a semi-mux if your exec doesn't have them, so it would probably be next to impossible to indoctrinate your car to them. Auto locks, as above, a nuisance. Unless you live somewhere where you're likely to be robbed sitting at traffic lights. Auto lights, my D9 had them obviously but I set the sensitivity to max so they were on all the time so I didn't have to remember in the day time (legal requirement in winter months here in Croatia). The yoyo doesn't have them (turn up the base ) but they come on with the ignition anyway, so that's the way it stays. All year. I suppose you could inseminate this into your car using an ignition controlled relay though.
You have to keep telling the car it has them over and over and eventually it'll believe you

Re: Semi mux to full mix conversion
Thanks.. It means nothing can be done to get such functions on premux.. I wish i can get the engine wiring and dashboard wires to buy.. Could have try it onsteve_earwig wrote: ↑Wed Jun 08, 2022 11:55 am Nope. None of it affected the powertrain.You have to keep telling the car it has them over and over and eventually it'll believe you
