T6 Adblue & electrics

Hi everyone,

Well my first 2 months of ownership of a 2016 T6 Highline panel van is sadly not proving to be a happy experience. Having owned a T4 for the last 23 years with that wonderful 2.5 TDI AJT series engine, I have been reluctant to move on to a newer model, having heard numerous tales of their complications. However, as the dreaded tin worm is slowly eating its way into the T4 & the fact that as it is still on the original clutch that will need replacing soon, I took the plunge & bought a T6.

It's a tidy T6 Highline 150bhp. It has done a high mileage, but it had a factory rebuilt engine fitted about 27,000 miles ago. Despite its well used mileage, it drives quite nicely. It threw the auxilary belt in the first few days, so we trailered the van over to my excellent mechanic, who had it for a couple of weeks & went through everything he could find. He replaced all belts & tensioners, oil & filter change, new battery, wheel bearing etc. etc. Now the dash warning lights are starting to appear. So far we've had glow plug light (he thinks probably caused by the turbo - there's definitely some 'whine'), coolant temperature, probably sensor, as it's the only code that comes up on a dianostic scan, but no real problem as there's plenty of coolant in the system & it doesn't rise above normal running temperature, now the battery charging light has come on, but the new battery has been coded into the ECU, so maybe the sensor module next to the battery, or an alternator fault ? Anyway, the T4 is in with the mechanic having new door locks fitted (in 23 years it's had more door locks than I've had hot dinners !). When that's back the T6 will be going in again for further investigation. It was a pretty cheap van, so I was fully prepared to spend a hefty amount to sort any issues & providing these issues can be corrected, I have no complaint in that regard.

So, a couple of questions for you experienced T6 owners. The van is Euro6 & has the separate Adblue tank, but despite going through every function on the MFD, I cannot find anything that tells me how much Adblue is left remaining in the system or any SCR reference ? If it doesn't have that capability, presumably some sort of warning will come up on the display telling me when to top up the Adblue ? The other thing is, I feel I should invest in a suitable scan tool, which can hopefully read any error codes on the T6 & also work for the T4. I don't really want to spend hundreds of pounds on one, but some recommendations of suitable ones to buy, would be helpful.

Any advice appreciated. Many thanks
 
On the Highline, the ad-blue info is in the MFD, scroll through the pages you’ll see MPG/oil temp/instantaneous mpg/ad-blue range etc.
Unless the Ad-Blue has been deleted by a previous owner.

My T6 Highline doesn’t have the ad-blue in the mfd - we discussed this a few months ago and we suspected that my ad-blue had been deleted. Still not had to put any in so I assume that it has been deleted.
 
Many thanks Salty & Fintious too. That's very interesting. I've just gone back back over all the MFD data carefully & there is definitely no mention of Adblue. So, I'm assuming that this has been deleted on my van also & that there is no further need for me to put Adblue in ?? If this is the case, I'm a very happy man, as that's one less thing to worry about ! I'd done a factory reset on the MFD panel a few days ago, to see if it would clear any of the warning lights (it didn't help). It didn't reactivate the Adblue on the MFD, but I guess it wouldn't have, as I suppose deleting it can only be done by mapping ?? My T6 has definitely been used commercially & given the mileage, I'm sure the Adblue will have given the previous owner problems in the past & hence deletion ?
 
Bought my 2019 T6 Highline (5 speed box, low output engine) with just short of 220,000 miles on a year ago. Figured, owt that had gone wrong has been replaced/sorted.
No service history, never turned up/got found/was even there?

Got the DMF changed, ALL belts and oil/filter and had no problems whatsoever.

It now has 230,000 on and I've NEVER put any AdBlue in.

The option isn't in the MFD so it's been coded out as far as I understand.

Not been under yet or had a close look at the DPF to see if it's internals are still there.

Found out that mine had been doing 500 miles a day delivering NHS supplies around the country.

All gravy.
