Official Mexican / Brazilian Beetles - All years

Going back to the strange buzzing from the car...Well I intend to replace the coil, As I needed to mention that the main clicking was coming from the by passed alarm and also the distributor....and the car does not crank even after being on a 48hr charge...

New to the forum.

I recently bought a 2001 MexiBug. Since I've been driving it, I've noticed that the generator light and brake warning light are sometimes lit, but extremely dim. So dim, you cannot see it in the daylight unless very close to the speedometer. Occasionally they go out completely like normal, but I have only been able to observe this at night.

Occasionally, the brake warning light will flicker with engine RPM at idle, and come on solid for maybe half a second while driving.

Yesterday leaving work, the generator light and brake warning came on solid. I stopped to ensure I still had a fan belt in place, then drove home and checked the voltage at the alternator running. It measured around 11.6v which I feel as too low. After it sit for about 4 hours, I started it to see if the lights would repeat the same issue. To my amazement, both warning lights went out after startup.

Today, I don't get a generator light at all. It will not come on when the ignition switch is turned like usual. Being around a bug or two, I know if that light isn't working the alternator will not charge. After I test the bulb in the speedometer to make sure it works, what is the next step in diagnosing this issue? Anyone have any ideas about the cause?

could be worn brushes or bad brushes'springs making erratic contact on their rings.

the 30 relay did not work and I guess I will have to get a coil....
Autozone has them, but i will go to my local VAG parts store that deals in Aircooled and foreign cars to get it special ordered... The adventure continues

Well I removed the unit behind the speedo to check where the cable would go(since my Immobilizer is a different model to the one showed) and when replaced notice that the alarm horn did not go off...mmmmm... which I get at least one beep still getting the coil just in case..
Mr Hopkins what gauge of wire did you use...?

I was unable to close the roof on my car the other day. After some testing today, I discovered that the switch on the dash has gone bad. I checked the back of the switch using my scope camera to see if any of the terminals may have fallen off:

Everything looked OK, I also 'jiggled' the wires to see if one was just a little loose.

I order a new switch with built in jumpers:

It should replace the existing switch without much change to the appearance:

(The switch is a 3 position DPDT MOM Switch).

The open position of the switch is still operating, so I rigged up a temporary terminal so I can manually reverse the polarity to open and close the roof as needed, until my new switch arrives:

I also ordered some VAG connectors to replace the screw-type terminal at the motor and to allow me to fabricate a 4 terminal pigtail for the switch:

Even though the roof motor is fused on the panel (at fuse #8 ), I think I'm going to put a second in-line fuse at the motor.

Hi Paul,

Nice work! The new switch looks identical to the old.
Where did you order it?

Can the old switch be disassembled, or is it a one-piece unit?

Greetings,
Gerrelt.

Having been through a few different steering bosses and endless head scratching, I finally found a boss to fit the '99 Mexi. The spline is a 26mm, but I was hoping to get a Mountney wheel & boss fitted...Mountney bosses only go up to 23mm.
I ended up buying a MOMO boss for a MK3 golf, which fits perfectly, in case anyone else has trouble with doing this job in future.

No love... replaced the coil bridged the alarm module, still clicking in the immobilizer and no cranking???

just a clue the Immobilizer is Immobilized or jerry rigged to work and both fuses are good... I am thinking to unhook the battery and let it sit 24hrs

frankly speaking I have no clue what could it be. unless the immobilization of the immobilizer, as you call it, somehow failed and is thus now immobilizing the car.
