Everyone has the same problem..your hope is that someone replaced a pair and has an old one still working…usually eurocarparts is the best price supplier..
Not sure mate. Mine's a 2009 so I'm assuming the later. I'm gonna pull it out tomorrow and see if there's any chance it might just be a bad connection or dirty points. I mean, it's unlikely but anything's worth a go. £270 for a replacement
Will be a 3 most likely then. I've got a right hand/offside that I took off mine in the loft. Was working fine when taking off so if yours doesn't clean up on the connections, let me know and can discuss
