ParticipantHi guys,
The new Leon is going well so far but have a small problem with one of the rear lights.
A couple of days after buying the car, I noticed that the outer rear drivers side light had some condensation in it, the light which has the brake and indicator.
I left it a few weeks to see if it would evaporate and clear but it is still there.Took it to Seat yesterday for them to have a look at it and the service guy took some photo’s and noticed a tiny crack between the seal and the glass, and he thinks that the lihjt has been hit at some point so will not cover under warranty 🙁
The external glass is not damaged in any way, even above the internal crack and is smooth with no marks or scratches to suggest it has been hit.
It is so small that I would never have seen it without looking and no real way of knowing if it was there when I bought the car or if it has happened since getting the car and Seat are saying the same.
Here’s some pics…
Condensation
And the internal crack where the light is bonded together
As said, the external glass is perfect with no damage whatsoever.
I know that the Subaru BRZ had a recall due to condensation in the rear lights.
This was caused due to over tightening of the mount bolts which caused the seal to crack allowing water to enter the light.
I am wondering if I have a similar issue, or if I have just been unlucky.If any other mk3 owners are having similar problems please let me know.
Cheers guys 🙂

MemberI would suggest if your getting no joy at the dealer take it up a level see if you get a better answer there, I mean a lamp unit to seat it peanuts so I would fight til the death for a replacement unit as it such a new car
Good luck 🙂December 14, 2013 at 5:38 pm #7034sixysix
ParticipantCheers guys, I know what you mean about modern lights and the problems they can have 🙁
Just that it is pretty new and as said, light unit at cost for Seat is nothing really.My Dealer has offered to split the cost of a new light so am considering that as an option.
Light costs £146 inc vat, so will cost me £73 not including fitting which I will do myself as it’s easy enough, well assuming nothing has to be reprogrammed by the ecu which I doubt it would.Did nobody notice the spooky face in the last close up image then? lol

Participanthi guys,
Got my replacement light yesterday and fitted between the showers and all seems good now 🙂
Cost me £61 as I don’t think they added the vat on 🙂Not sure if all Seat, VW, Skoda, Audi are the same fitment wise, but I assume so, so will add a little how to to save some of you breaking you’re outer rear lights 🙂
Should be simple really and is when you know how but if you can’t see how the light mounts, it’s very easy to break bits 🙁
There is a diagram in the manual and even I thought I understood it but obviously not.Anyway, first open boot, Locate the little cover which is parallel to the light and remove to reveal the light mounting bolt.
Remove the mounting bolt with a flat head screwdriver by turning anti clockwise.Once you have removed the bolt from the boot, you need to the top right edge of the light on the rear wing.
There are two bolts which are a push fit into rubber mounts in the rear quarter panel, these are the bolts…The bolts are here when light is fitted to vehicle…
Standing at the side of the car with the rear wheel facing, you will need to grab the outer edge of the light and pull it towards you to release the bolts.
Remember they are push fit so there is nothing to undo.Once the two bolts are clear, the light will slide out to the rear of the car 🙂
Replacement is reverse of removal.
I was careful but tried wiggling the light a bit before I knew how it was attached and both the push fit bolts had snapped off on the old light 🙁
It is pretty easy to remove now that I know how lolPictures are of the original light which had the crack in the glass, I have managed to dry it all out, glue bolts back on and silicone sealed the light all the way round so is all good for a spare now if I ever need it 🙂
The only time you will really need to remove the outer lights is if you need to replace the part, or replace a bulb.
If you have rear led lights, the only bulb that I can see that is replaceable are the indicator bulbs.I am in no way responsible if you follow this guide blah blah blah lol
And if you do muck it up, maybe this will help lolHow this helps someone in future 🙂

ModeratorDon’t sound quite as easy to remove as the MK2 I can literally do a full set in 15 mins

ParticipantIt’s easy if you know but most lights I have ever removed were, undo bolts and pull out and unhook wiring 🙂
The light will take a minute to remove now, just pop the outer edge of the light on the wing out before sliding out the rear.
Silly design if you ask me though, although an easy way for seat to make some extra bucks lolDecember 20, 2013 at 6:59 pm #7049AndrewJB
ModeratorYeh they will probably charge you an hour for it.

ParticipantAfter washing the car today. I noticed i had the same problem. Drivers side rear led light cluster. Also a small crack in the same place. Maybe my light got hit by the same person. Or maybe its a manufacturing fault. I shall speak to my dealer on monday.

ParticipantJust noticed to same with our new Leon (2 years old). Nearside rear has a crack in the housing with no evidence of an impact (frozen condensation?) and the offside is full of condensation. Seems to me the seal must be defective – we will be interested to see what the dealer says at the next service, coming up soon.

ParticipantJust had the exact same problem fixed under warranty by Seat dealership on my two year old Seat Leon ST. No quibble whatsoever from dealership so it may well be a common problem.

Participantlots of people had this (on another forum) – all deny hitting anything, so it must be extra-fragile or brittle plastic. Good height for shopping trolley handles maybe? Some dealers will swallow it, others refuse and Seat Customer Services won’t normally pay.

ParticipantJust bought a 1 year old MK3 SC. Noticed condensation in one of the rear light clusters. Garage manager said this is a known problem and changed it there and then.
