2006 E350 Dead ECU
 

Hi,

My car died on me on my way to work the other day. Its a 2006 E350 4matic. Dash flashed "coolant malfunction - visit workshop" then "display malfunction" and also "esp malfunction". There may have been one more warning..maybe "abs malfunction". I know..i know...a girl panicked coz the car literally stopped itself and I was fortunate to be on a lane where I immediately swerved to the shoulder. Thank God no fast cars were right behind me. Anyhoo, my mechanic says the ECU is dead. The car would not start and it would not communicate with or something like that. I am trying to avoid the "stealer" (term I learnt browsing through this amazing forum..haha) so I am asking for direction if anyone knows whether a rebuilt ECU is a good option. I chanced upon that idea while googling. Any help, thoughts, insights to help a girl out will be appreciated.

I am a complete dufus in matters mechanical. Like I know where the coolant fluid goes and where the oil thingy is. And I could figure out where the starter coils go if I looked hard enough.

Thanks for indulging me. Much appreciated. Hope you have a blessed day/night whenever you read this.

Thanks.

Welcome to the forum and sorry for circumstances.
Replacing ECU is like replacing your heart- you don't want to do it base on opinion of first doctor.
So IMHO spending $150 or so for stealer troubleshooting is not a bad idea. Very often multiple errors are result of low voltage and if the mechanic is trying to milk you on the job, he is not going to be first one.
