ballistic Posted August 19, 2021 Share Posted August 19, 2021 The dials on my main cluster are all reading at extremes. Sometimes after turning the ignition on and off multiple times they start to read correctly. Believe it or not. Im not out of fuel while at 9000rpm doing 250mph with 200 C temps. Im actually sat on my driveway. (Also i haven't done 600,000 miles) Tried replacing the air con control unit: Didnt help. Anyone experience anything similar? Any suggestions or advice appreciated. 1 Quote Link to comment Share on other sites More sharing options...
Willsy1980 Posted August 19, 2021 Share Posted August 19, 2021 Possibly a bad earth maybe ? Any other symptoms or just a whacko cluster ? Quote Link to comment Share on other sites More sharing options...

Willsy1980 Posted August 19, 2021 Share Posted August 19, 2021 Have you checked the fuse ? Think there is one in the foot well that does all the cluster. Not marked up as instruments though. Quote Link to comment Share on other sites More sharing options...

Not marked up as instruments though. Agreed - i had this once when i'd popped a footwell fuse - but given this is intermittent i'd say the fuse is unlikely, and more likely a dodgy earth on that circuit, which could be a bit of a nightmare to find. 1 Quote Link to comment Share on other sites More sharing options...
ballistic Posted August 19, 2021 Author Share Posted August 19, 2021 As mentioned its intermittent, so i doubted its down to a fuse. But i checked em anyway.

Do you remember which fuse it was? It could be that the second air con controller is also faulty. unlikely though. If its an earth, im not sure where to start Quote Link to comment Share on other sites More sharing options...
marzman Posted August 19, 2021 Share Posted August 19, 2021 No idea sorry... happened o me in 2008. 🤣 Quote Link to comment Share on other sites More sharing options...
Willsy1980 Posted August 20, 2021 Share Posted August 20, 2021 From a bit of searching, think its fuse 6 maybe Listed as battery 10amp electrical parts. As you said though, 2 units in the aircon that can cause this too. For the bad earth/electrical issue start with the obvious, test the battery and the connections are good.

Pretty much everything online is pointing at that being the issue or the wiring associated with it. Some have had issues after installing aftermarket audio etc but they were cutting into it for 12v ? Other than that unit and fuses is it possible the cluster is faulty ? Could turn in to one of those you just keep throwing money at parts to try and diagnose :/ 1 Quote Link to comment Share on other sites More sharing options...
HEADPHONES Posted August 20, 2021 Share Posted August 20, 2021 I feel your pain Ballistic. This has been happening with our 2006 Mini for over 2 years Mine is related to moisture as it's more frequent after rain on initial start up. Normally goes away after a few minutes driving, but when my dash looks like this the AC stops working and the Speedo stays at zero with all the warning lights lit up like a Christmas Tree. My garage can't find the problem and the Mini forums say it could be a loose solder in the dash SOMEWHERE Quote Link to comment Share on other sites More sharing options...
marzman Posted August 20, 2021 Share Posted August 20, 2021 Are the ribbon cables that go into the white AC control unit okay? Not folded or pinched or anything? Quote Link to comment Share on other sites More sharing options...
ballistic Posted August 20, 2021 Author Share Posted August 20, 2021 thanks guys. checked every fuse and rechecked the ac controller. No success yet. @marzman ribbons on both the old and new are fine. Going to replace my passenger hub tomorrow. After i will have a look at earths and take out the cluster and have a look.

ballistic Posted August 24, 2021 Author Share Posted August 24, 2021 Thought i would give it a few days and see what happens. Still playing up. Sometimes they spring into life after driving a while. The exact same symptoms people describe resolving with a air con controller replacement. Quote Link to comment Share on other sites More sharing options...
