Anyone able to help please?
2011 i30 1.6 crdi, trying to change fuel filter but can't for the life of me get this ****ing connector off. Can anyone explain/ have pics of the underneath (why the hell did they put whatever locking tab there is below so you can't see the bloody thing . . . . .) how to get it to disconnect?
Cheers.

Hi mate. Know your pain, so been out and took photos to help you.
There's a red lock tab that you have to push to the rear of the car - then press the tab under the plug and wiggle it off mate...


There you go. Puch red tab forward to relock once back on.
