Short and sweet- I need some ideas of where to start ...
 
Started with-
cruise control stopped working all together
tach and speedometer work sporadically
radio shuts off and turns back on
at red light, car loses all power and shuts down, put in N, starts right back up (3 times now)
Alarm started going off and on when opening unlocked door
headlights and dash lights will dim and brighten on and off....
  
This has been transpiring over about a year but the stalling is worrying me. I would appreciate any ideas (other than taking it to a dealership or getting a new car!)
  
We disconnected the alarm from the box behind the right tail light so my daughter will not be mortified again by the blaring horn at the orthodontist- LOL
  
Thanks for reading and offering advice!

hi,
If you took the battery loose it might be in immobilizer mode,Check the inst cluster if there is a car with a key in it ,it's in that mode.also radio code will be missing,double check wiring plugs especially the crank sensor,,A scan tool would help here,read the codes out...
you could jump the coil to 12 v and see if it cranks ,
Now the bad part.... might have to replace the ECM or have that one reprogrammed.The life span on them is like electronics heat and over 5 years old isn't good.
I have read you can get the part # off your ECM and find the SAME # one and it will work,,,but I can;t find my #
Good luck,

HELP!!!!
I had a good shop rebuild a Automatic trans in my 2,0 cabrio,When I picked it up the engine was idling pretty high ,The mech said it needed to break in and maybe a tune up,Well the engine ran fine in park and started ok So Tune-up what? I drove it and read online how to reset the user adaptions that helped but still 2 feet on the brakes at red lights,About a week later 250 miles or so I started to hear a knock from the hood,wasn't a spark knock but enough that you could know it was there ,after about 60 mph the knock would disappear until you let off the gas then it was back,,,,a few days later the knock got LOUD and I parked it,I did check the oil the first time it knocked level was good and no metal visible in the oil and the oil was new,I pulled the pan and rocked the crank back and forth damn big knock,so I started pulling rod caps and checking them all ok,Then I happen to look at the torque converter and the 3 nuts that hold it to the crank plate where almost off the studs so I tightened them and torqued them and check for a knock ,it was GONE,I put it back together but it will turn over NO knock but will not run ,,,,has fuel pressures,spark ,check every sensor added raw fuel to intake,I had a MAF and A cat 1 error in code scan,but those are replaced now,I?m going CRAZY That same shop couldn't find anything wrong with it and another $350.00 down the tubes,lol I'll take ANY suggestions !!!!!!!!!!!!!!!!

Hi,
I had the same problem here's how it went my needle would float and not go past 50 I found the pickup and replaced it ,It's on top of the trans under a plate mine is automatic I believe it to be a A1 transmission.
If that has been done there are places that repair the cluster,You can look inside for burnt parts, capacitors,they are mustard yellow color and have 2 wires coming out usually the tops turn black,if so get a electronics person to replace all of the capacitors,there not expensive.
There's also one other problem. if the Transmission is worn out the sensor doesn't read the drum inside very well,,,you know the rest of that story,,,,
Google vw cluster repairs in Texas,,,,,

hi,
Just a guess but replace the brake light switch,,,and check the wiring around the brake pedal for wearing or shorts,
I am thinking the ABS and running lights wires might be shorting together some where ,check the wiring harness for rubbing in the engine compartment ,check the plug on the abs module to make sure it is tight. Did you scan the codes? most autoparts places will do that for free.It might narrow it down for you!
Good luck!!!

hi,
Check the cranking amps of your battery,then measure your battery could it be a little longer or wider?Then match it up.I bought mine at walmart,One with more cranking amps is ok just not less,
And as long as it will clamp down to it's mounting plate, it will work fine ,BTW they will install it for you Too! and give you $5.00 for the old battery!
Do get your radio code before you change the battery,it's in your manual or google it! and of course the dealer has it too!

#97 of 109 2000 Cabrio windows no longer open from inside the vehicle by mskydancer2

Does anyony know a way to reset or reprogram switches? The car windows can be opened by putting the key in the door lock and turning it, only. when trying to use inside switches a barely audible hum or whirring sound can be heard and a clicking sound comes from beneath the dash. Has anyone had this problem and if so do you have a solution? All directions in the owners manual fail to remedy the problem. Msky

Well it's been more than a year since you posted this and I'm just looking at it now. Did you resolve your problem? Sell the car to some poor schmuck or take it back to the VW brain surgeons so they can steal your kitchen sink too? If you haven't solved the problem, please tell me what the fix was. I've had the same problem and many many more electrical issues with this car.
