Hi

From about 2010 some of these cars increasingly seem to come with steering wheel paddle change. Having come from an MMT Yaris and a Peugeot 1007 Sport I've kind of got used to having the paddles and its the one thing I miss big time with the 2008 Aygo and 107.

I've seen paddle change equipped steering wheels from C1's and Aygo's sold on ebay for fairly sensible money and I'm tempted... but does anyone know if the wring loom and connector is there on the pre 2010, standard car.

Its shown in the Haynes manual - but whether that is just because the manual covers vehicles of all ages. What I'm hoping is that, like the rev counter, there will be a nice unused connector block on the dash assembly, ready to take the paddle connector from the new wheel - but I cant afford to fork out £50 and several hours taking a steering wheel off, only to find out it isnt there.

So can anyone enlighten me please? All info gratefully recieved.

If only it were that simple. Steering wheel aside, there is lots of other gubbins you would need to source, fit and configure to even have a hope of this working. Sooooooo not worth it - sorry.

I think we may be at cross purposes here. I'm not asking whether it can be done? I already know that it can! I just dont know exactly how much work I'm going to have to do.

So can you be more specific about what else I need to source? Because from what I KNOW - and what I've read in the tech manuals, even the early gearbox controllers DID have the connection terminals for the three wires that go to the paddles, and indeed the programming for it to work. They have to because essentially the same system is already active when one drives the car in manual mode. ALL cars including mine can already do that, using the gear shift lever to initiate the changes. So from that I surmise that actually it actually cant be that difficult to fit the dupllcate system.

What I dont know is if the paddle terminals on the gearbox controller plug just dont go anywhere, or whether the wires are there in the harness - and then the only problems would lie in the steering wheel and dashbaord assembly. In reality I'm just being lazy - I can and will find out by dissasembly and tracing it all through, but I was hoping someone would already know and save me the voyage of discovery.

It really isnt that complex a system mod. The paddles are simply like logic switches - you take a line momentarily low, and that causes the gearbox computer to initiate a change up or down. I know exactly how it works because I'm a graduate engineer with over thirty years experience of computer and electromechanical engineering. I know the logic is all there - because as I said it has to be, otherwise the existing manual driving mode, which all the cars have as standard, by using the gear stick, simply wouldnt work.

The system - is activated by moving the gear lever into the manual position - and in the cars that also have paddles fitted, the paddles then also become active, acting in parallel to the switches on the gear shift assembly. That much I know - what I dont understand - and want to know is precisely what additional bits I would need other than the steering wheel with paddles, to connect them through from the steering assembly to the controller. Clearly there needs to be a wiring harness - what else? Oh an I have an ODP programmer - and the necessary access software so I can enter any necessary changes to the ECU and Gearbox system.

On manual cars the 'gearbox controller' is the driver. There isn't any electronics controlling the gearchange.
