I'm troubleshooting a no-start problem on my sister's 1996 318ti. At first we were confused as to why the battery was dead and the car wasn't starting after a jump. I found a post on this forum about a problem with water getting in behind the battery and destroying the DME (ECU) and indeed there had just been a big rain storm here. We opened it up and confirmed that the DME was full of water and the circuit board was badly fried. We removed the dead DME and dried everything. I bought a replacement DME on eBay (same part numbers, stickers, etc, same year too) and we swapped it in. The car is still not starting and we see the "check engine" light come on in Position 2 and never turn off. The starter does kick over fine but I haven't checked if the fuel pump is energised yet, it seems like there is no fuel and/or spark. Any ideas on what to try next? Before removing the dead DME we confirmed that the fuses are in good shape (we replaced the fuel pump, rear defroster, and cigarette lighter fuses) and all of the important relays are working (bench-tested), at least the ones we believe are for the pump and DME. | | | 10-25-2009, 11:36 PM | #2 | Senior Member Join Date: Jul 2007 Location: norcal - 94590 Posts: 3,186 | The replacement DME must be "aligned" with the EWS II module. Usually has to be done by a dealer. __________________ James 95 active w/leather interior and sport interior conversion, Vaders, full M-Tech exterior conversion.

So we have to tow it to the dealer for sure then? | | | 10-26-2009, 12:53 PM | #4 | Senior Member Join Date: Apr 2006 Location: Oxford, Ohio Posts: 868 | Make sure you clean the drains or this new DME may also go for a swim. | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
