Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that contain suggestions: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suggestion
There's an option for it in the settings menu (I believe under Set > Display with the lower left stalk).

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1Original post

987.1 CS - Does anyone know what "----" on the tach means? I can't seem to find any documentation on it. Curious if anyone on P9 knows! Intermittently comes up but stays persistent until you switch off. Don't believe there's any issue with the cars operation but does make me feel my DME is doing something funny. Will attach a pic as soon as I work out where to upload it

POST 2Original post

Do you mean below the current speed, or instead of the speed? If it is below the speed, thats additional info controlled by the lower left stalk (OnBoard Computer). It probably is set to display some data that is not available or was reset. Could be lots of things. Do you have an after-market radio? Regardless, try switching to display something else.

POST 3Original post

Mine does this intermittently if the radio is off and I have that portion of the display set to show radio / CD info. There's an option for it in the settings menu (I believe under Set > Display with the lower left stalk). Not sure why it's intermittent, it's generally blank if the radio is off but I guess sometimes the CANBUS gets a little squirelly on that front? I guess the question is: does it go away if you turn on the radio? Assuming your head unit is the stock one, that is..

POST 4Original post

Thanks @RSchwerer & @immerohnegott ! I think you are both on the money - I have the OEM BOSE system, very rarely turn it on so mostly stays off. I'd be curious if the intermittent behaviour is an indication to something flakey attached to the CANBUS. If this is it, then this case can be closed

POST 5Original post

I'm almost certain it is because you've got an aftermarket radio. To confirm, that immediately shoed up when I went from my OEM CDR30 radio to a Sony head unit....and I lost the radio station/song titles in that exact spot. I'm going to try and code out the CDR30 with my PIWIS 2 in the next few weeks and hopefully that will remove it; it's more an annoyance than anything.

POST 6Original post

I just flick the OBC stalk to display something else - like TPMS tire pressures. My radio already displays what I'm listening to. So that other OBC display would be redundant regardless. Since it is easily removed, I see no reason to try to code it out.

This is a source reference. Confirm exact model applicability in the original material.
