I tried to check the oil level on our 2006, 206 gearbox and removed the LH wheel arch liner to get to where I expected the plug to be - according to a Haynes manual for 206 which covered models to 2002. It was not there as shown in the manual.
Asking around, I was told it had changed to a plug matching a square drive in the 5th gear housing. I have not been able to check with a later Haynes manual and wonder if anyone can confirm the position of this plug on later models - a picture would be great.
Thanks
