AddBlue MAN 180 TGE

[Dave100456]

Hi, I'm really pleased with my MAN TGE engine in my Knaus motorhome; there's a but coming.......

However, I'm concerned about the Addblue system. The Addblue tank was full when purchased new in 2023 and indicated 15,000 mile range. I've done 11,000 miles and not topped up at all. The range did drop to 12,500 but currently shows 15,000.

I've had no engine warning lights and whilst it's nice to not have to buy Addblue, I'm concerned about emissions and possible MOT failure in the future.

Under warranty the vehicle has had a new addblue injector fitted but this hasn't changed anything.

Any other TGE owners/user able to comment on their Addblue consumption?

Thanks
Dave

Hi

I don't know for sure Rod, there are 4 engine codes for that era and DAUA SY is a 18L tank, till about 2022 ish. I was only try to compare quantity to miles to gauge consumption.
If is a 30L tank, then it makes sense, as mine full tank range given is about 8K miles.
Dosage is default VW I haven't played with the quantity. What I have observed on VCDS, the add blue is not used all the time as the oxidiser does most of the work up front. I didn't know that, But also when under load the add blue comes alive.
That confirms 379inca and tht3 posts above.

Hi Raul , as a follow up to AdBlue capacity and consumption of a Crafter or TGE.

My TGE is a 2023 model and currently shows 11472miles on the odometer. The quoted AdBlue range is 5000miles and the maximum fill should be no more than 5 gallons (22.7litres). So as you say above this one must have a 30litre AdBlue tank.

I've just looked at the parts listing and there are at least seven different tanks shown for a 2017 onwards Crafter/TGE.

AdBlue systems are are dark art worthy of Hermione Grainger... no two are alike.
I've got one of the good ones 22k miles & filled twice, 3x MOT'S passed.
