Had nothing but problems with truck from new,had it 18 months now as for drivers windows had to put sellotaptape over top of window to pull it in at 56(with other windsow open)on 4th set of batts 2nd microvave,2nd frigo…build qualitly ■■■■■…
Essix Blue:
Anyone else had issues with it? Seems it’s a known fault on the new FHShow’s ad blue warning and imminent loss of torque if not rectified.
We’ve got a unit been in last week, Volvo are aware of the problem but aren’t sure how to fix it.
The same unit has thrown the problem up again today - back to the workshop it goes…
Volvo, Volvo, Volvo…
Shakes head & ■■■■■ teeth slowly…
Mine is really heavy on adblue
50 LTS 1200 miles
My 12 plate would of used about 30 lts
Still only go 20,000ks on the clock. so hopefully settles down
All about DPFs if you’ve got 1/2 hr to spare.
Bking:
Purge air pressure too low in diffuser valve.
Pain in the arse.Happens a lot if you stop the engine without full air in the all the air tanks (especialy high pressure auxiliary tank which feeds diffuser valve,suspension etc).Adblue is left in diffuser and the heat off the engine evaporates the water in the adblue and crystals form in the diffuser blocking the feed apature.This then puts the light on as it monitors adblue flow into the exhaust system.
Remove air feed pour a kettle of boiling water into the valve to melt the crystals,reconnect the air and rev engine to max for a few seconds.This removes fault but you need diagnostic to turn off the light.
Wow!!!
I actually agree with you

euro 6 vs euro 5?

Very interesting and very very scary.
Didn’t have 30 mins to spare gave up after a couple of minutes,so I may repeat what he said …pro for EGR is the engine gets up to temp quicker.AD BLU usage sholud be lower ,as the vehicle will run primarily on EGR …If you have to do a forced regeneration in the snow ,the heat generated will melt it in minutes 
…Downsides, when it does regenerate I burns the soot off which in turn becomes ash ,you can’t reburn ash ,so your 100% efficient DPF after it’s first regeneration will for a figure is only 99.8% efficient ,with it dropping each time it regenerates,till eventually it becomes blocked with ash ,where it then itself needs to be removed and cleaned out…And going by the components in euro 6 exhaust systems is not going to be quick, cheap or easy…If you want to go EURO 6 without EGR ,then IVECO are the only one to reach EURO 6 with AD BLUE /SCR only …The Italians obviously know someone no other manufacturer knows
Scania have worked it out as well now… 
They unveiled an SCR-only 450 at the show in Hanover a couple of weeks ago.
I saw a Euro 6 drivetrain this week. Apparently under forced re-gen the exhaust temperature gets up to about 800 degrees C… Wouldn’t be doing that when there’s a risk of anyone standing near to it.
Never knew about scania managing it.learn something new everyday …There is all sort of warnings about how to park when doing a forced regen,to make sure you don,t set nothing on fire …At least there is a switch so you can prevent a regeneration if your in a refinery for example …That definetely would not be good

I wonder if all manufactures will end up dropping EGR, as, unless I’ve misunderstood the video it’s only used under certain conditions, to reduce NoX and increase exhaust gas temperatures. But under normal operating conditions it’s not required.
Better NoX treatments and other ways of raising the exhaust gas temperature should make it obsolete. It also seems the the dpf is actually a cartridge type thing which can be replaced without replacing the entire exhaust system.
I’ve heard or read somewhere that euro 6 motors need to be specified with a power output matched to the work they’ll do and shouldn’t be over powered. If this is true, is it something to do with getting the correct exhaust gas temperature?

Yes pretty common in the US… Cleaning it gets it back to about 90-95% of original… (depends on how it’s done) for a couple hundred $… cheaper than replacing it… There seems to be a ton of places doing it…
