Also are you sure that you didn't bend some of the pins on the chip. Also hopefully you didn't get an static shock when you touched the board or chips. That would screw up everything too.Quote:

HPE gives support too, but doesn't know what could or went wrong.
I can't find a name that rings a bell.
The support print needed to be welded into the masterprint because the cover won't fit after using the normal connector.
You can imagine when replacing the original again and welding again, it was no fun job to do. Specially when I found the same problem: no start.
Someone said I might have fried the computer: what does that mean? Do I need a new Bosch?

I would not buy a chip that requires the cover to be left off, it's not a good idea to run it like that as the DME has now protection now.

It doesn't need to be disconnected. Does the M5 DME have a 2 circuit board, with the boards face to face like a sandwich? My 525i's have this type of board, but some cars only have a single board. With the two boards, you need to separate them and it can sometimes be difficult. It is possible that you either cracked one of the boards or somehow scraped one of the lines on a board and DME no longer works. If you can't see any damage to any of the circuits, than I don't know any way to tell other than trying a new DME. Mark, who makes the EAT chips, also repairs DME circuit boards. If that is the problem, you could send it to him.

The sandwhich board I have is not so easy to open but I've bought a magnifying glass to see whether something is cracked or scraped or...
I'll let you know.

(and don't forget to release those two tabs in the housing also)
Here's where you need a Hindu goddess with a few hands to help change the chip.

Yes it is a very good upgrade and unbeknows to be there was a Dinan chip in there. The new chip is far superior but I have seen the little increase in MPG. Probably it is because I haven't been able to keep my right foot of the pedal.
