A friend of mine has one of the above that has sentimental value....remove the “senti” and that’s about right Apparently the pump in the adblue tank is not operational and needs replacing refurbing.....any ideas?
a 2005 C5 will not have AdBlue, it will have the ELOYS system and there are kits available and YouTube videos showing how to refill the under car tank. It will need connecting to a LEXIA (PSA reader/computer) to reset the ECU counter.
NP....my mate also has one, not the biggest fan but I understand why he likes it. A fabulously big estate car and I have to agree there is nothing out there that comes close to the comfort and load it can take with that suspension.
