V50 Electrics : Vida reports ADM/DPF errors

[goltho]

I took good advice here and got a new VCX and laptop with Vida pre-installed from @CheshireD5 which arrived earlier this week (thanks Simon).

The V50 goes in tomorrow to my mechanic buddy for new glow plugs as at least two are bust. This was evident from previous diagnostics I ran and subsequently confirmed by checking the plugs themselves. However....

Daughter (whose new car it is) brought it round this afternoon (she's in our bubble ) for me to check it over with Vida after a few weeks of using the car. Turns out that in addition to the yellow warning ! due to the glow plugs, the red triangle has been appearing, first intermittently but now permanently.

Apart from the glow plugs, Vida reports the following: -

ADM-0002 Additive level sensor - Faulty signal
ECM-2A20 Particulate trap - Faulty signal
ECM-A610 Additive dosing module (ADM) - Qualifier unknown

I'm attaching one of several reports which all pretty much say the same thing. The DPF pressure sensor appears not to be working due to reading 0hPa all the time. So: -

• Is that a reliable conclusion and would it cause the ECM-A610 error through the absence of data?
• Is the ADM-0002 error likely to be caused by (or causing) the ECM-2A20 error?
• Might the fact that some or all of the glow plugs being bust for an unknown length of time and presumably preventing regens from happening, have something to do with any of it?

All input gratefully received.

Dougie.

It's a good question and one I'll hopefully have answered tomorrow when it's on the ramp.

Vida Dice should be able to read the level as well

Well this is my first Vida rodeo and I hadn't got to that thought yet. I'll look at that tomorrow. Thanks Iain.

Presumably though a low and especially empty tank would generate an error?

definately theres a you tube vid that shows toping the tank on a c30 v50 will be similar if not the same

Double check that the two pressure pipes to/from the DPF are intact and not worn through. The sensor is mounted to the side of the battery housing and two ~10-12mm pipes run to the DPF. Check the length of them to ensure they are intact.

Iain, I asked my mechanic buddy to check the DPF vacuum sensors while he was doing the glow plugs, and he spotted the two pipes were the wrong way round. I ran the car through Vida when I got home, and the sensor is now reading correctly.

What now show as DTCs are a faulty additive level sensor, particulate trap blocked, and an ECMA610 ADM - Qualifier unknown error which I'm sure is down to the lack of info from the ADM.

So the current situation is: -
• When checking live info, the ADM pump and ADM sensor are both showing as not working
• I ran two manual regens which appeared to complete correctly. However, it was after the first one that the Particulate trap blocked error appeared.

I've ordered PAT fluid and will fill the tank next week despite not knowing whether it's full or empty due to the allegedly faulty sensor. The car meantime went into limp mode this afternoon.

I still don't know whether there actually is a faulty ADM sensor and pump or whether the tank is empty (the level was reset blindly a month ago before I got Vida so to my mind, I'm inclined to believe that the ADM thinks it's full when in fact it's empty). Any input on this front would be much appreciated. Thanks.

Dougie.

From memory there's a procedure to read off the current level.
Most likely in Diagnostics >Vehicle Communication >ADM (from the overhead vehicle diagram) >Advanced

Additionally, for any fault codes, click on the code in the Initial State tab then View Information for an explanation of the fault and the possible causes and fixes.
