Dash cluster crashing / rebooting on startup
Hello all, I have a weird probblem with my 2003 A8 4.0 tdi which I wondered if anyone could advise on?
Most times when I start the car, especially if it has been sitting overnight, the car starts fine but the dash cluster goes black (as does the button illumination through the MMI unit etc) and after a few seconds the dials come back on bu the time has reset to midnight and the date to Feb 2003. This is sometimes accompanied by other warning lights (EML light, traction control, ABS etc) and sometimes not. I have VCDS and have scanned it which has given the following results - however I've only just got my copy of VCDS so not very clued up on deciphering the results - can anyone assist?

RPM: 630 /min
Voltage: 13.53 V Does it idle at 630rpm, or is that the cranking speed during starting? It looks like there are missing CANBUS messages at this time the codes are set - some of the messages are telling dash illumination to come on etc... If this happens again, can you manually turn the healights on and off a few times with pauses in between as this will send the illumination messages again. I would think a low battery would cause this but the freeze frame voltage shown is good, but was this voltage perhaps after the engine started (630rpm) |
The first thing I'd suggest you do is clear all the codes, as some date back to 2003. Once cleared, go for a drive (leave overnight if necessary to reproduce symptoms) and then scan again. Post that scan and go from there.
With regards to the current scan, I'd say it's possible a faulty connection on the instrument cluster, or, since both engine and ABS modules are throwing errors, then (if the same errors reappear), check the physical connections to these ECUs for water ingress, both of which are in the plenum chamber, and open to the elements. Also pop along to the Introductions page and introduce yourself. We also have an affinity for photos, so brownie points on offer there. |
