Clear them. It says they are "shadow errors".

Shadow code is pretty much something that was stored a long time ago that pretty much is not in the system anymore, just something saved over time.

Re: Wtf a solenoid valve....

I think with your car you have to jump two pins under the hood, to get it fully connected.

Tock and I tried to get PA soft to connect to my OBD, it was giving some sort of connection error for the coding part.

Indirectly, I had mentioned this to Mango and he mentioned the jumpers, sorry I don't have more details.

is that the "PA soft" software. It seems to display "shadow" codes. Google it. Or search forum. As near as I can tell shadow codes are nothing to worry about and PA soft (at least the chinese bootlegs) can't clear shadow codes. You can clear them, then next time you scan the same ones will be back. As near as I can tell you can ignore these shadow codes. Of course, I could be wrong

The round 20 pin connector under the hood should have a cover and the cover should have jumpers in it. If the cover is installed on the round connector under the hood, the OBD connector in the car should work??

I do not have an older BMW so I cannot confirm this 100% but this seems to make sense.

PA Soft will display all sorts of errors, you need to ignore most of them as they will drive you crazy. A low battery can cause all sorts of codes to show up as well.

Thanks guys, starting to actually question the battery myself as when you buy a used car you never know what condition the batteries in, might drop in somewhere and ask if they can check it.

Especially convertibles as many times they are not primary cars and they sit a lot and the batteries get drained due to parasitic draw from the alarm and other modules.
