This morning after couple of minutes of driving error Engine Fault: Repair needed and Emmision fault showed up on my Citroen C5 Aircross 2,0 HDI with also amber AdBlue light(photos attached). I have checked the level of Adblue and it said 2,400 km. I put 10 litres of AdbLue (until the top) and after ignition there are no more error.s I drove for around 30 km and there is no error and car is acting normally. Can this be a solution or additional checks are needed?

Re: Citroen C5 Aircross: Emmision fault Engine Fault
Fairly good chance it will have been a crystal in the adblue system, If no warnings it is good to go. Some users af Adblue systems put anti crystal additive in, I do but still get the occasional fault then it goes away, I have found I have less faults using Total Adblue from the fuel station pump.
Thanx to all the admins & knowledgeable people that make this the best forum on the interweb. BUT COME BACK MARC , We miss you!

Re: Citroen C5 Aircross: Emmision fault Engine Fault
Thank you Steve for fast response. Just note that after the error I turned off and on car several time but the error persisted. After putting the AdbLue at the gas station (from the tank) and after ignition the error disappeared. Lets see what will happen because I am suppose to go for a vacation and 2,000 km trip in total within a week. So you would suggest buying that anti crystal additive?
