Time for a new ECU DME
 

Well,

After the defect of bmw not fixing the hoses behind the firewall and when you take a E36 to a car wash, the ECU compartment gets flooded with water and thus can ruin the ECU.

I tried to fix it. however it does not work, Pelican parts http://www.pelicanparts.com/bmw/tech...DME-Repair.htm
has a great guide on how to do it.

However I believe my ECU is damaged beyond repair and my car simply won't turn over. :wtf

Has anyone had any difficulty swapping a ECU? I talked to my BMW mechanic and he said the ECU thing is quite common.

Any advice or guide on how to get the part?

??? Thanks

What year car do you have, and what version ECU do you have?

its a 93 325i , the ECU is a bosch ending in 413

should be really easy to replace. simply unplug the old, plug in the new.

call a dealership's parts dept. and ask. If they dont know ask for service, that MIGHT but usually just deal with customers.

I tried to use the OBDI by stepping on the gas pedal 5 times but the Check engine light doesn't flash or anything.

DME fried
 

Here's my story.

Maybe it will help:

yeah i ordered a new ecu on ebay, i'll swap out the chip and do exactly what u did. i just hope its not the fuel pump...

So It turns out that it wasn't the ECU after all(installed 2 new ones and the car still wouldnt start), so i checked the fuel hose where the fuel rail is and guess what...no gas coming through, soo I think its the fuel pump, my car has 145k miles and was running strong before hand...

i got one off of ebay(brand new) for 160(2nd day delivery)

hope it works
