Adblue delete?

[Palazzo 477]

Looking at the exhausts on this which look like a 90s Bighorn, is this poor running or the result of deleting the blue system?

Prob never been cleaned. Deleting adblue would only turn it into a NZ spec vehicle

Just curious, never seen one with that level of soot around the exhaust.

That level of black soot is more likely to be poor running, worn turbo, clogged injectors, overdue oil changes, etc. Possibly jammed up EGR valve.

My understanding is that the AdBlue system is to reduce levels of the NOx emissions, which are much smaller / finer particles than the soot, by a chemical reaction. So no AdBlue shouldn’t mean more soot, unless it’s not been done properly and now it’s not running right..

You only get soot deposits on the tailpipes of Diesels that have had the Cat's removed.

Diesels with Cats = clean tailpipes.

Probably had a DPF delete.

The DPF takes care of all the particulates... adblue only converts the NOx gases to CO2 and are not visible.

Did the E70 come with a DPF..? It might have in some markets, EU maybe hence the AdBlue which wasn’t required for NZs lax emission rules.

All the more reason why people should not be allowed to muck about with emission control systems on cars. Really pisses me off, glad to see they are starting to pick up on this kind of dumbf**kery at WoF time now.

All e70 diesels have DPF AFAIK, was a market option on the last of the e53s too

looks like a faulty exhaust system.
