ECU sub-connector problem

tufgsd · 07-11-2010, 02:43 PM

Ok, I think I really screwed up now. I was removing the JB3, the removal process was going very smooth. So, I take out the large connector and the slider comes all the way out. No biggie I though, i just set it aside. After plugging all the factor stuff back together, I put the connectors back on, except I forgot to put the slider back on the large connector. So, now not only does my car not start, the big connector will not come off, for me to add the slider back in. I know the reason is the conector is not all the way in for the car to start.

Anyone have any advice or thread that they can point me too?

Similar thing happened to me - I was able to get my fingertips underneath the connector and use them for leverage to pry up the connector evenly on all sides. Hope this helps.

pulling the ecu out of its tray should make it easier. Just pry the two tabs holding it in the slot.

During the install you pressed on a tab on the ecu subconnector to take the slider out.

Press on the same area on the subconnector (it is on the top) with your small screwdriver and it will lift out easily.

Then attach the slider and press the slider in as you lower the subconnector, they reattach as a unit.

well the issue finally got fixed for $2K and 3 weeks later that BMW charged me. I did not tell them what I did, but they claimed that the ECM became corrupt. Not sure how, but I was not going to question it. I need to find a local mechanic that knows how to work on 335i in Little Rock. BMW is killing me on prices.

what did they replace for 2K? do you have a list of parts on the service invoice?

Wow...they robbed you blind...Make sure you see the invoice and ask them for the parts back if thats the case which I doubt...You car didn't start was because the connectors were not seated right...All they did was take the subconnector out replace the slider and connected it back, but only thing that went wrong was that they made 2000 dollars for themselves..

My guess is they replaced his DME which is 1500+ Labor....2k seems about right.

alextremo · 08-03-2010, 05:56 PM

you really couldn't get the connector off? Or did you fix that and still couldn't get the car started with it attached properly?

Here is what the invoice says:
Installed 12 14 7 611 358: RMFD Basic Control Unit --$1368.11
Installed 51 71 7 237 195: Support Lifting Platform -- 4@27.79 -- $111.16
Labor $524.75

Now here is the question: Do I get an extended warranty on the DME since they installed a new o

I would have rather gone to a local mechanic that knew how to work on these cars instead of dealer, but I am yet to find anyone in Little Rock, AR.

I really could not get the connectors off. Tried all suggestions from Forum members. Plus had an angry wife breathing down my neck..........

Now it makes sense that you paid $2K to get it fixed.

You should get a 2 year unlimited mileage warranty on the DME.

A local mechanic wouldn't be able to replace your DME, I don't think it's plug&play. But a handy JB3/Procede user would have a chance at taking the connector out.

He took a 2 thousand dollar punch, square on the chin. Poor guy.

I wonder if the ecu was really corrupted or just an excuse to give him a new one.
