I just finished coding my 2009 E90 335 with the downloaded software and bimmergeeks cable; Worked like a charm (f**k you e-diff)

But my fathers 2007 E90 335 (06/2007 build) just cannot connect. We get a ecu not connecting code: 'COAPI 2020'.

Any ideas? We have done some trouble shooting but no progress.

what's the build date of the car.
cars made before and until 3/07 used k can but
really a K plus D can cable should work on either car.
Also I though the Bimmergeeks cable has a switch
for something to do with the OBD type.

-Built in switch for double K-Line support (E46, E38, E39 etc)
the above from there site but I didn't think it effected the e90.
Might give it a try anyway.

I always try functional jobs with Inpa to make sure I have
a connection to do a sanity check on the connection.

Have you updated datens?

[neilvan]

Car is 6/07 build so its after that split. Also datens are the latest versions.

Confirmed inpa to have connection and ignition each time before opening up ncs expert.

We have the adapter from bimmer geeks but it made no difference either way

It will work as long as the switch is all the way to the right on the cable. Make sure com port is set to 1 and latency 1 ms. Which modules are you getting that error on?

[Red_Bean_Bun]

JB4 on that ride ?

[neilvan]

Com port is 1 and we have no switch on the cable. Ill check the latency but it did work on the 09.

Im getting an ecu not connecting error(even though INPA shows connected and ignition).

Jb4 is always turned off before trying

[gabylonfive]

if there isn't a switch on the cable you can accomplish the same result by bridging pins 7&8 on the pcb inside the adapter.

[neilvan]

Another look back and we ended up getting the "one stop electronics" cable that has been recommended a bunch of times. It has an adapter for K can to D can instead of the switch.

That being said with it being an 06/2007 build car (after the 03/2007 split) it should be D-can which works on my 2009.

[ctuna]

Your logic is defective.
k can up to 3/07 06/07 is and earlier date than 3/07
therefore its kcan. I thought the switch on the bimmergeeks cable
allowed it to work either way.

[sdbmwcoding]

I agree, it's not your cable. The bimmergeeks cable will work fine with both e90's. If the car has jb4 I guarantee that's the issue. Load up inpa, functional jobs and error memory. Post up picture of all modules responding.

Sorry for the confusion; I'm doing months/year. 3/07 would be March 2007 correct? This car is June 2007 so 6/2007 or 06/2007 I'm using interchangeably

Assuming this is what you mean?

Funny we just tried it on our 04 E83 X3 (with the adapter of course) and got the same error.

What adapter? The bimmergeeks cable has a switch on it to re-pin it for certain models. For the e90 put it to the right, for the e83 put it to the left. No adapter needed unless it's a very early model that requires a 20 pin connection under the hood

I was wrong on the brand; We don't have the bimmergeeks cable, rather the "one stop electronics" cable. Both were recommended on the forums and that's the one we got.

Instead of the switch it has the adapter for K Can.

If the datens work with a 2009 E90, they shouldn't need updating to work with a 2007 E90. Probably KCAN-DCAN issue as discussed

I mean tt could be but I thought this was a D-Can car being after 3/07?

[ctuna]

You are right I must be dyslexic.

[dpaul]

It seems that most people say that 03//07 is the changeover. However, I remember at least one poster saying his 06/07 E90 was K-line. So there might be some variability in changeover dates.

One way to assess would be to look at the pinout in the OBDII port. That requires removing the hood latch lever and a panel or two. A bit of a pain. DCAN (I THINK - didn't look this up) will have wires on pins 6 and 14. K-Line won't, just a wire on pin 7.

But have you tried connecting using the K-line adapter that should have come with the one-stop-electronics cable?

Yep. Adapter or no adapter is the same result as you see above

[dpaul]

Have you tried to use a commercial scanner on the OBDII port on that car?

EDIT: sorry, I'm confused. The pictures you posted show the COAPI-20 error then show INPA apparently reading module error memory correctly. So it works after pressing OK on the error message?

[neilvan]

Yep we have the Schwaben tool and it works/reads as it should.

Im honestly just as confused. Once we clear the message, it doesnt go through and has the same options/stays on the same page.
