Hyundai i800 "Urea System Service" (AdBlue)

[darrenham]

MIL has one of these people-carrying-van things. I've not seen the error myself, I'm just remote tech support, but it's telling her the Urea (AdBlue) system needs a service.

She's friends with someone who runs a Kia garage who won't touch it, and her friendly local mechanic won't either.

Is this a service as in a standard "every x miles" thing? Or should we be concerned that something's wrong? As I didn't think these needed a service any more than a fuel tank did.

I've told her to ring the local Hyundai dealer, but I'm getting third hand info via the wife so I don't know if that's actually happened yet.

Any ideas in the meantime?

Sure it doesnt just need topped up with Adblue ?

Seems strange Kia wont touch it when it probably has an identical model to Hyundai.

What does Hyundai dealer say ?

[darrenham]

Yeah, she took it to her friendly local garage who normally top it up and it wouldn't take any more. It was overflowing.

Yeah I thought that was odd.

Hyundai have just booked it in for a diag. but wondered if anyone had heard of anything like this before.

For those who GAS, it was a sensor in the AdBlue tank.

I've had this message come up on my i800, service urea system or engine will not start. Turned out to be the breather in the filler cap, I had recently filled the adblue reservoir and must have caused a vacuum. As soon as I took the cap off it cleared the message. Phew!

I know this is a late reply, but I had a similar issue with my Hyundai i800 and ended up spending a fortune to resolve the issue. I have written about my journey and how I fixed this issue with advice and guidance. I hope others who suffer the same problem can benefit from my long, painful and expensive journey.
