Just want to say hi.
So I have a problem with my 2014 Doblo 1.6multijet 105 126000kms
The speedo doesn't work when driving, glow plug fault when cold, but not when warm, engine light on all the time and ABS, Handbrake and ASC lights on, also the outside temp shows temp for 1m03secs then goes off. These all happened withing 30minutes of each other and are still on at the same time. no fault codes stored.
I have checked all that I can find earth points in engine compartment and in the interior of the car, battery connections, all fuses. these all seem to be ok.
If it is possible to post a video I have a video of the problems

First I'd use a temporary jump start cable (the type with big crocs either end) and connect between battery -ve terminal and a good metal point on the engine...
Make sure the slack/excess cable has no chance of getting entangled on moving items...

and retest

Done that, Made no difference.

... and the battery is a good state of charge?

Please provide battery voltage when off and rested for 30 minutes and also when running

I'd be checking connectors (for ECU and BCM) for loose fit and/or water based/corrosion next

Battery when resting is 12,48V and 14,2 when running

could you provide diagram of where to find ECU and BCM please as i have trouble finding them. If it is the one on the bulkhead then checked and all clean of corrosion.

Try disconnecting the battery , count to ten , then slap the the connector back on cleanly (I.e. don’t faff/dawdle with connection)

Retest

done all that, even left it of all night.

Update, no codes coming up on obd11 reader, decided to check the glow plugs manually, number 3 glow plug down, replaced, that sorted the glow plug problem. still have ambiant temp going out after 1min03secs and ABS, handbrake and ASC lights still on, with no codes showing on the OBD. wondering if the OBD is actually reading anything...
