AD Blue

[cjb44]

Do Range Rover diesel engines fitted with an Ad Blue system suffer from the same problems as the Mercedes diesel range of vehicles. Mercedes in particular seem to suffer from blockage in the bottom of the tank and filter along with failure of the sensors in the exhaust system. These items being an expensive fix, it would appear that the filters cannot be cleaned or replaced and only are available as a complete tank unit.

Come on guys, someone must have an ad blue Range Rover

I don't know, having only filled the tank up once since purchase and I m not aware of any known issues.

The ones I know of (i.e. Mine or close real-world friend) with Adblue were all 3.0 V6, as follows:
17MY Discovery: drank it like a pisshead in Weatherspoons, 10L was 6-8,000 miles. Google JLR Oil Dilution issue.
18MY Discovery: normal. 12-14,000 miles for 10L.
18MY XF Sportbrake: similar to 18MY, but a pig to fill up as the filler is in the boot.

Not heard of any with the issue you describe.

Does anybody else’s adblue tank take forever to fill up? It took me about 10mins to put 10litres in yesterday. Anything more than a dribble just over spills.

Mines a MY19 D5.

All pretty common with trucks. Nox sensors can and do fail, the actual quality of the liquid you are putting in the tank has a huge bearing on things. Once in the open air it forms crystals, these get flushed in the system and blocked pipes and nozzles follow.

Thanks for the replies chaps. From what I have gleaned from this and other sources I probably should steer clear of any AD Blue vehicle,
my use of a car is sporadic since downsizing and it would appear that with this system they like to be used on an almost daily basis to keep the fluid moving and preventing crystalizing in the tank. The answer I guess is to go petrol which is not an issue for me except that few manufactures make anything with a decent sized engine (that is within my budget).
