Hi, is there any of you guys who have heard about this parking light LED problem at the Vantage.
My left front LED parking light is dead when my Vantage is Cold ! First i thought it ws the Whole frontlight unit that had to be replaced.
By a coincidence i found out the following: When i heat the cabin inside really hot, the LED parking lights starts to flash and then work steady.
At first i found it funny and thought it had to be the heat in the engine bay that dried out some moist in the engine bay fuse Box.
I then turned on the aircondition really cold in the coupe and the LED parking light went off just minutes after.
I assumed it was the heat that expanded the Whole coupe fuse Box.(front passenger side under the carpet) I changed all the fuses in the coupe fuse Box, since this was an easy operation and quite cheap.
It did not help. So then i Wonder if any of you know what relay it could be that Works the front parking lights. The main headlamp hig and low is working fine all the time.
It's only the front left hand LED park light that is having problems.
I think it is something that expand in the heat inside the cabin and make contact. I havent changed all the other fuses in the engine bay and boot. since my focus is inside the cabin due to the heat fact we know.

 

I assume you're talking about the LED turn signals? Mine were acting up, but seems to have fixed itself. Hopefully it stays that way.

Apparently it's a common failure of bits of the circuit board inside the headlamp that controls the flashing, exacerbated by condensation over time. See here for more info

Hi, the Turn signals Works fine. The LED diodes for the turn signals is attached a centimeter further back than the two parking LED diodes on the same plate.
Aparently they are on different Controls/system. I really dont think the problem is inside the headlamp since it starts working when it gets really hot inside the car. i suspect a crack in a printboard or a faulty relay inside the car,
I just received some Electric diagrams from an AM dealer. will try to check more into the fuse and relay boxes..
I am very glad if someone who have heard about this problem will assist us in the forum.
Thank you.

 

Sounds like a bad solder joint on a PCB that is separating when cold and making connection when it heats up and expands.

Here's a thread about it from a couple years ago:
