All sorted!
Ok just my 10p worth!
I have a 2010 leon FR..
Initially I ordered the wrong part code, if your lock isn't prefixed with a D then don't order the one that is... i learned the hard way! However, they eBay
store that i got my locks from just sent me a replacement no questions asked!
I did the passenger door 1st.... you must read all the instructions, because like a typical bloke, i didn't... basically i left the window mechanism, where it was and pulled the door card off it... not realising it would make it harder to put back together, with a little messing i still managed it tho!
Also, make sure you have all the correct tools before you start, i rounded the door screws slightly, so had to use some pliers to get them off.
The rear door was pretty simple too, following the instructions above!
So far both doors now work perfectly! and cost me around £80 for the 2 locks! Seat quoted £330 for parts alone, then £60 per hour labour, so id guess around £500-£600 for them todo the job..
Hope it helps someone else!
