Ad blue p20eb00 fault

[Druzis]

Maybe some one had similar problem as mine p20eb00 fault in engine ecu. It all started when i added the ad blue to the car. After that came the p20eb00 fault. Maybe there is solution to this problem? I've read all the post about the ad blue problems but it seems that different problem in my situation because of different fault code. I retrofitted water heater recently maybe i codded it wrong and it could affect this problem(it works like it supposed to at the momment the there is now roof display connected because i'm waiting for new headliner)? The range dropped from 1000km to 850km at the moment.

Well you have

04194 - Vehicle status with insufficient voltage
P056200 - System Voltage Low Voltage

Low voltage can cause all kinds of issues so give her a good charge first, then clear the faults and scan again

 

[Druzis]

I have already deleted adblue system on my car. I tried replacing a reductant power relay, Adblue tank itself. same fault was so the most easy option for me was to do a delete for reductant system.

Hi,

Did you ever solve this issue? We have the same issue and fault code with our transporter. Would be really good to know what the problem is and if you have solved it?

Thanks in advance

Sadly no, i did the adblue delete. With all the system left in the car. It’s only programed out.

Ok thanks for coming back to me. I think I might have to do the same. So frustrating. Did you take this to garage to be deleted?

It’s “programed out” (don’t know how to call it corectly) all the adblue system parts are still left in the car. Reductant system is turned off in engine ecu by the diagnostic guy who came to my place and done it like in 10mins and took 80€ from my pocket…..

Me too. 5 visits to stealers so far and no solution although codes are currently only pending
