Brera third brake light

Not been able to find anything specific on this hence the new thread.

The third brake light no longer works on my 5+ year old Brera.

Must have happenned recently as only just passed its MOT.

It's not the fuse so has to be the wiring or the unit itself.

Has anyone else had a similar problem with their Brera?

Could be a wire broken within the loom that enters from the top near the roof into the hatch.
You need to pull off the rubber sleeving and see

Certainly could be a weak spot.

Will check as you suggest

No obvious break in wiring so decided to remove lamp unit.
This necessitates removing the roof spoiler.
Removing interior trim on rear hatch reveals four 8mm nuts attaching the spoiler.
Even with these undone however, spoiler still feels attached somewhere in centre but I can find nothing obvious.
Anyone have any idea if there is another fastening?

Nobody any ideas on how to remove the rear spoiler then?!

Oh well! looks like a bit of easy money for the dealer.

My bodyshop guy had to cut/re-splice the brake-light wiring
when re-spraying the spoiler on the Brera.

He couldn't find any way to disconnect it.

From the Brera service manual -

1. Undo spoiler retaining nuts
2. Disconnect the connection for the rear screen washer fluid pipe
3. Disconnect the electrical connection for the third brake light
Lower the tailgate
1. Lift the spoiler slightly and release the duct seal
2. Remove the spoiler and third brake light.

The electrical connection to be disconnected is near the rear washer fluid pipe.

Thanks Nev, but I'm struggling to get the spoiler off in the first place, I haven't got as far as the connections yet.

Thanks Parcstroman, it seems that it is the 'duct seal' that is causing me the problem rather than another mechanical fastening.

Not sure what the 'duct seal' is exactly as there is nothing visible, it may be a rubber gasket or just sealant, but I can now approach it with a little less caution and a bit more convicton

Problem solved, wire broken where it attaches to lamp unit. Guess this could become a common fault as Breras get older as no doubt related to slamming shut of the hatch.

Thanks to everyone who gave me much needed assistance.

Thanks for the pointer to this thread

How did you break the duct seal?

Cheers,

Cheers,
There was actually a rubber duct seal (a big rubber grommet) which simply pushed out and a huge blob of mastic which was a complete pain to separate on my Brera.

From what I remember I used a mixture of hacksaw blades, serated breadknife, builder's line cord (a bit like dental floss for an elephant), a lot of gentle persuasion and even more care to break the mastic seal.

I found I had to GENTLY force a small gap between the spoiler and the tailgate to gain access to the mastic, carefully cutting through the mastic taking care not to damage the bodywork or cable running through it. If you use too much force, the plastic spoiler feels as though it will easily break.

I eventually managed to weaken the mastic seal sufficiently to separate the spoiler from the tailgate.

Obviously, the interior trim has to be removed from the tailgate to gain access to any of this.

When refitting I did not use any new mastic, in case it has to come off again, and so far everything seems to be watertight.

Good luck

Thanks. No problem disassembling everything once I was aware of the "blob".

Mucho testing with a multimeter identifies the piece of wire that connects to the loom in the car and the brake light (6 inches long) is at fault or one of the connectors either end.

Car is under approved used warranty so claims on the dicky alarm (I have a theory on that) & rocking seat are a no go.

I wonder if electrical wiring is included? It's booked into Guests Knowle tomorrow and I've left all of te trim off to make their job easier (in case of warranty coverage) or cheaper for me if I have to pay.

Fingers crossed!

Cheers,

Simon

Just read my approved used warranty book & level 2 standard coverage specifically excludes wiring & wiring looms

I've checked eper & have the diagram & part number for the bit of wiring with a plug each end is c£17 + VAT.

I had both dodgy alarm module and rocking seat base replaced under used approved warranty, no questions asked.

Mind you I never saw any warranty book with an actual description of what it covered and was told there was none.

Mine is a September 2006 car, purchased used but pretty much as new with under 4k miles on it last August from Guests in Knowle.

The warranty booklet came towards the end of last year and given the age (not the mileage), it's only L2 Standard Cover, despite being approved used.

Seat base & back rest is £2038 supply only

This wire is cheap so hopefully only looking at 1/2 hour labour, especially as I've done all the diagnostics & disassembly.......

That sounds just the same as mine which proved to be the connector which pushes into the lamp itself. That connector is not particularly robust with very delicate pins which can easily be bent to ensure a good connection.

Guess that is all they will actually do, it's all I did.

PS. I had the rocking chair fixed under the manufacturer's warranty but it's rocking again. Just having to live with it.

I love my Alfas and have done for the past 32 years but neccessity recently dictated the purchase of a 'practical' motor from a more common stable to replace the Spider. I am sad to say that I have now discovered what trouble free motoring truly means

So what's better about this Brera compared with your first one - aren't they both q4 v6 pre-08 models?

Both are V6 Q4.

My first was a 2008 facelift. It was good but I never gelled with it. The paint was crap & I fell out of love with it.

My new one is a 2006 car. It drives & steers / handles so much better.

This got explained to us at an AROC Section meeting recently by the man behind the S.

The much heralded weight savings came at the cost of rigidity in the suspension department.

The solid ARB's were changed for hollow ones but the diameter remained the same.

The Steel uprights got changed for alloy versions of the exact same design but alloy is 30% less stiff than steel.

I thought I was imagining it but back to back, the earlier cars are much sharper

Interesting - did the S have some additional stiffening then, or was (Peter Prodrive?) saying the S is a bit sloppy too then?

He was saying that if the dampers had been applied to the original (and development) cars, the results would have been better.

The changed components were a complete surprise!

just reviving this thread to note that I fixed my third brake light too this weekend - same problem of a dodgy connector fixed by squashing the metal clips of the female connector a bit.

not happy with the man in the Alfa factory with the silicone gun though - 2.5hours to get the rear spoiler off!!!

Duct seal

Does anyone have any pictures of the duct seal or the blob of mastic once the spoiler has been separated? I'm attempting to fix my middle brake light today, have removed the interior trim and the 4 8mm nuts but can't see where the seal is!

Thanks

Afraid not.

You'll need a 12 inch hacksaw blade or a sharp carving knife or nylon chord from a builders line, lots of patience, perseverance, courage and a bit of gentle force.

If you gently prize the spoiler upwards you should be able to feel the sealant with the blade.
It's then a case of prize a little and cut a little for an afternoon.

Good luck
