rearview mirrors flash red and green alternatly

My 1996 e300d with about 190k miles has an intermitant starting problem.

Sometimes the car will not start and the rearview mirrors flash red and green alternatly. Usually after a few tries the car will lights will stop flashing and the car will start. Could this be cause by the ingintion switch or some type of bad relay??? I bought the car used and do not have the electronic key so the car doors and ingition are always operated using the physical key.

As further information the car has stoped running twice when ideling at a standstill. (I have replaced the fuel filter and all glowplugs.)

Replaced the battery

Interesting, I just replaced the battry this afternoon, not because of this issue but due to it's failure. It started the car early but not after lunch.

When it got tested it was shown to have been complete toast......

In the past whenever red and green lights flashed alternatively in my rear view mirror, there was always a cop parked or cruising behind me.

flashing lights on mirror

The lights flash on the mirror when locking/unlocking the doors with the remote. I rarely, if ever locked/unlocked the car with the key, so I'm not sure what the lights do then.

better but not sure if it's fixed???

this problem seems to have gone away (low voltage from a bad battery about to fail???) however now my speedo seems to have stopped working causing the ABS light to come on....

I'm wondering about some type of relay or switch that is about to fail.....

Any thoughts would be greatly appreciated...

Since nobody brought it up, the lights on the rearview mirror light individually when locking (red) or unlocking (green) with the infrared remote. When you see alternating red and green flash, it means that the start lock-out is active, so I would guess that your '96 is equipped with this.

If not, the original price sticker will have a start lock-out credit of about $450, but even if it lacked the lock-out from the factory, it could have been added with a change in some electronic components.

To activate the start lock-out, simply lock the car from the outside, with either lock cylinder or with the infrared remote. To deactivate it, unlock the car from the outside.

Your low battery was probably confusing the system.

About the speedometer and ABS, if it isn't related to the battery change, it may be a dirty or bad wheel sensor. I'm not sure which sensors are used for the speedometer, but the rear wheel speed is not indicated on mine, as evidenced by driving the car in the snow (it IS possible).

red and green lights are back

Car started fine a number of times but now it is back to not starting and the red and green lights are flashing so it thinks it should be locking out the starting process.

Something I just noticed is that when the car actually starts the check engine light will come on with the glow plug light and when the engine starts the check engine light will go off. However, when the car is not starting the glow plug light will come on when the key is turned but NOT the check engine light. when this happens the green and red lights flash and the car doesn't start. however when the check engine light comes on with the glow plug light the car will start.

any thoughts?????

Try unlocking with the truck cylinder. The switch or wiring at the driver door cylinder may be flaky.

Truck meaning trunk.

I'm wondering about the OVP relay. ABS light is also indigative of Over voltage protection Relay failure.

But get the locking sequence figured out first.

Still intermittant starting

I took apart the drivers door panel and checked for loose connections etc all looks fine. In addition, once the car is open it may or may not start but if it does not start on the first try it might start on the second or third without locking or unlocking the door infact I stay in the car.

Are there any thoughs on OVP and what I might test.
