SE Drive & Ignition Fix
There have been a few instances now where the ignition key fails to turn the ignition switch below it. So far they have all been in Roadsters.
Although this can be done while the SE Drive is on the car, it makes more sense to remove it.
There are wires that can be damaged but if you take care you will be OK.
Info on removing the SE Drive can be found here.
What Does The Fix Do?
The problem is inside the SE Drive. Inside it is an insert that holds the gear change PCB and the ignition barrel, the problem is that this insert is held in by 3 plastic clips on each side.
If they unclip themselves, the insert can fall down, moving the ignition switch away from the barrel. With these two not touching, there is no way to start the car.
It is also possible that the sliding metal plate can become dislodged
and cause poor or restricted movement of the gear lever.
What this fix does is to join the main assembly and the insert with a more reliable fixing.
Applying The Fix
Mark two holes on each side as shown above. These positions have no wires behind them.
To drill safely it is best to push a small drill bit into the chuck so it only shows about
4mm of the drill bit, this will stop it going in and touching any electrics in the SE Drive.
Drill the holes nice and slowly, it's only light plastic so doesn't need a lot of power.
Using either a countersink bit or the tip of a bigger drill bit, countersink each hole.
The reason is that the screw can then lay flush and not interfere with the cover.
You need to find the shortest countersunk screws you can get.
The plastic is about 4mm thick but you lose some of that when you countersink.
I used 3.5mm long screws as it is what I had, these do protrude slightly.
If your screws do protrude into the SE Drive, cover the points with a
bit of duct tape to stop any possible rubbing on the wires.
