Condensation is real bad in both lights....cheapest ive been quoted is £170 just to strip down the lights an reseal but cud still leak...

I read sumwhere u can drill small holes in each light it wont condenstate....

Wt u guys rek?
 
Drill holes and the condensation will be far worse!!

I had this problem, its the gasket seals, I took the backs off the lights (inside the wheel arches, the ones you take off to change the bulbs) I then thoroughly dried out the lights using a hairdryer!!, watch for the water that sits in the tray at the bottom, you will see what I mean when you are doing it,that bit is the hard one to get rid of, you can if you are brave get rid of the worst of this with a straw!!pryor to this I bought new rubber gaskets (came with the covers too) put them back on, no condensation whatsoever. total cost about £18
 
Pain in the arse problem!

I doubt it would be advisable - I'm guessing they're sealed that well for a reason! Putting holes in might help rid the moisture but let dust and other things in. I'd be inclined to remove the lights, take the bulbs out and dry them out for as long as possible. Then go round the edge with some sealant before putting back. There are a few posts up at the moment with a few pointers.

Good luck!
 
id take the lights off the car and get a hair dryer on them to dry them out, its probably the cover at the back that isnt sealed (changing the bulbs is a real pain, id suggest taking the bumper off and un screwing the lights to change bulbs on a table) drilling them isnt wise and they are not cheap to replace, i was lucky to pick up a nsf halogen on ebay for £63 recently. but pairs are silly money - £300 - £600, a pair new from bmw is around £750!
 
I though they all had a drain on them anyway with a rubber tube to stop crap getting in, I know the fog ofrom my E46 did.
 
Fog lights I assume (and headlights already have bult in air vnts covered with a rubber grommet and mesh to keep dirt and bugs out

The simplest answer is probably to just use them and they'll dry out. They are likely to fill up as the air expands and contracts with normal fluctuation and changes in humidity, each time leaving a bit more water inside.

If that fails, bumper off, take the bulbs out and dry the lights. Check for any cracks or damage them put them back in making sure the seal is clean and intact

Doubt drilling a hole will make any difference really and risks allowing spray and dirt inside.
 
i am talking bout the head lights....

if i take it to the garage tomorow an get them to take the back of the lights out, dry out the bulbs etc, can they try and use a sealent and put the backs back on or do i NEED to buy the new back covers????
 
They wont get the lights apart without cutting them - have a look at CJ's post on his AE project... If they take the light out and remove the bulbs this should give enough of a vent to allow any moisture to come out by heating the lights.

I would get them to check the vents CJ mentioned - that they are there was news to me TBH!

I would try and avoid splitting them. Odd that they have both gone? Might be worth just checking that if someone has replaced the bulbs previously that they've put them back properly. May be worth re-sealing the edges too? (to add - I mean the edges of the lights, the join, if you take them out!)

EDIT: Now with added link...

Shows what's involved in splitting these things!
 
OK - headlights.
So as I mentioned they already have air vents built in.
No need to take the bumper off. Just turn the wheels (but easier with them off) and open the wheel arch inspection hatches. Remove the light rear covers and dry the lights with a hairdryer.

Inspect the covers and if the seal is damaged, twisted, etc. get new one's from BMW. Don't use sealant else you'll never open them to change bulbs.
 
r these what i need ???

Left:
63 12 6 928 413

Right:
63 12 6 928 414

About £9 each, and about £2.50 for a new clip

n thanks all.....
 
Yes - but check they were clipped on correctly, no wires trapped in them and seals OK before spending money.

(I assume in all this that there are no mods like aftermarket xenons as the feeds may have been poorly installed)
 
no mods m8......i had a guy change my bulbs a couple months back (bit of a cowboy) struggled his arse off aswell...so i think il take ur adive an make sure they have been put back on correctly at the garge, if not il get the rear covers/seals...

thanks again m8

I assume we are talking fogs not headlights?


AAhh I assumed wrong, thought he meant headlights :headbang:

It was the condensation what gave it away ... :rofl:


You get condensation in the headlights if the seal is not pushed home right or worn, anyway it turns out he was talking about headlights :P apology accepted :lol:

As i said in my post, its no good just taking them to a garage and re seating them, you have to get the water thats in there out, otherwise it will just keep doing it.
 
I had this, hair dryer plus new seals works a treat. That said I would like to clean the inside of the lamps at some stage (condensation left a film). Any ideas?
