My local garage has had a look and says it needs a new computer...... I know very little about cars but I am not sure how a single brake light stops working due to a computer fault. There is nothing I or the garage can find physically wrong with the light.
Also previously the same garage had said the unit for the front running light was corroded but now think a new computer will fix that as well ?

My question is is the above situation even possible and am I being ripped off ?

Any advice is greatly appreciated as they aren't asking for peanuts

Is anyone able to advise of a decent reliable garage in the Swindon area ?

Also helps when I put this in the right place
Check the hatch wiring before doing anything else. If the wiring is damaged (and it's an extremely common problem), then diagnostics can't be trusted.

The first thing to do with the recalcitrant roof is to run an initialization procedure. I posted the page from the 500C supplementary manual a couple of years ago but basically it's this;

1. With the engine running, make sure the roof is fully closed.
2. Hold down the 'Open' button until the roof is fully open, i.e. right to the boot, and continue to hold the button down for another two seconds before you let go.
3. Hold the 'Close' button down until the roof is fully closed and again hold the button for another two seconds before releasing it.

The roof, unless there really is a problem, will then automatically go through a complete opening and closing sequence and should function normally thereafter.

The 'blown' LED in the brake light has probably succumbed to condensation. The only cure is a new brake light which is fitted from inside the spoiler. Forum member BigKev outlined the procedure a couple of years ago and I'll try to find the post for you. Basically it involved pulling the trim above the window aside and undoing about four screws to remove the spoiler.

Later;

Quote from BigKev;
“Well, actually I had a go at this last year (this is an old thread). The rear portion of head lining is unclipped, then four screws are removed to release the spoiler, then the whole LED unit can be replaced. On assembly, apply more sealant to the four screw holes to combat leaks, replace screws and headlining. Fiddly working in the back of the car (it is for me as I am a huge fella!) but not difficult for a competent DIY type.
The new LED unit is hellishly expensive though, at over 100!!!”


And here’s the link to the thread with the 500C manual page;

Good luck with it.

Re: 500C - high level centre brake light

I just had to remove my third 500c brake light due a some of the LED's not working. I've had the car from new and the Brake light has lasted 5yrs ...not good really .

Ordered a replacement from today , Fiat Part number : 77365246 @ 155 !!!

As they always seem to fill up with water I thought I would take the old light apart to see where it needs sealing to stop the new one leaking and becoming faulting again at this silly price!
The issue seems to be around the red lens and its mount to the lens backing , so once the new one arrives I will be sealing around the light to try and make it last longer then 5yrs !

To gain access to the light is quite easy once the roof lining is removed and the previously notes written on this are quite easy to follow but here are a few pictures of the lining and the lens apart showing the issue with the SMD ( surface mounted device) Led broken off the circuit board , I suspect due to the damp of the water getting into the lens .

Re: 500C - high level centre brake light

Thanks for posting those pictures. If the LEDs are not broken, it might actually be possible to solder them back to the board. A bit fiddly but not impossible and at that price certainly worth a try.
