Adblue System Problem In Citroen Grand C4 Picasso - posted in Diesel Domain: I have Citroen Grand C4 Picasso with BluHDI 200. Recently Ive got a message that Ureal level is low and I need to refill it, otherwise I cant start engine in 1100km. I went to official service (Sing Huat Premium), they topped up Adblue tank, but the message still remain. First time I've heard about the tank itself, but there have been recalls for the AdBlue wiring harness and tank cap on some versions. Sounds like you have a helpful dealer at least. There have been many reports of issues with the Adblue system. It occurs right across the Citroen diesel range.

Tanken/posen er placeret under bilen, nær brændstoftanken. Vær opmærksom på, at der skal tester til at nulstille tælleren. Good morning, I have a Citroen c4 Grand Picasso 2014 2.0 BlueHdi 150 horses. - message - refill Adblue. Of course there is Adblue in the tank. Everything else - no errors. Is there any way to cheat the signal from the level sensor? A resistor or something? Finally, I have an infusion under the 7th seat and I am able to keep an eye on the level C4 Grand Picasso AdBlue. ker si lastim omenjeni avto (l. 2015) in nočem, da me servis "odere" , sem se postopil natočiti AdBlue tekočino kar sam. Ampak imam težavo, ker pokrovčka od rezervoarja ne moremo/ne znam odviti - v navodilih piše, obrnite za 16tino obrata in odstranite pokrovček, vendar kljub trudu ne gre. How to reset the service on Citroen C4. Water temperature sensor replacement. Volkswagen Passat (1996-2005 / B5, 3BG) Open the hood and locate the temperature sensor located under the windshield. Remove the two hose clamps placed on the water duct to be able to remov. Cooling water temperature thermostat replacement. The AdBlue Warning came on this morning. It said starting would become impossible in 1500 miles. I went straight to my local cart parts shop, and bought 10L of AdBlue. The manual and also the AdBlue cap both said add at least 3.8L needs to be added. I poured in 4L and there was still space. 6L - still space. 10L still space!? ctdhTEa.
