Were they the 150bhp Engines?I did some programming on some Californias over the past weekend and 2 out of the 5 T6s had EGR faults that they were not aware of.

1 x 150 and the other a 204Were they the 150bhp Engines?
It is truly shocking that you are still having all of these issues @Twoguns. Especially when you were possibly the first one here reporting it, and how VW pretty much ripped your adblue system apart.Quick update.
Dealer just called and they believe the EGR is at fault and will be replacing it once they receive it from VW. I asked him if they are going to investigate why these EGR’s keep failing as my van is now on EGR number 3 after only 16000 miles.
Basically he talked some not good and said they will just be replacing it.
I’m no Engine or car technician but I am an electronic technician and used to fault finding and if I had a component that kept failing, alarm bells would ring as something else must becausing this component to fail and I would be investigating further to work out the route cause and not just put a plaster on it.
I am pretty sure this new EGR will fail in time as I know fully believe there must be something before it that’s not right.
I have always suspected the engine is not right and heard a lot of talk about these new Euro6 engines not being as clean or as well developed as they should be.
I know what you mean, it’s a joke.It is truly shocking that you are still having all of these issues @Twoguns. Especially when you were possibly the first one here reporting it, and how VW pretty much ripped your adblue system apart.
Well at least that’s made it formal; a representative of VW has admitted there is a fault with these components. Like you my sceptical mind says, “what is the trigger?” something has to be happening upstream for these to keep failing in the way that they are. Let’s wait for the recall............. turning purple already!I know what you mean, it’s a joke.
Picked “it” up today after they replaced the EGR again. EGR number three so I’m expecting this one to fail at some point as I cannot accept I have been unlucky and had two defective EGR’s. My logical and technical brain screams there must be something else that it causing the EGR to fail as it just can’t cope with what is being put through it.
I was not surprised when the Service Manager admitted I’m not the only one to have EGR problems on these T6’s and they have had to change a number of them now. German engineering at its best........
Hi Mate, unfortunately I’m still suffering with the same fault and I’m on just over 20000 miles. I’ve had the fault on and off since around 3000 miles. I’m currently driving around with it on now as I’ve had enough of it but stuck with it until maybe the elusive software fix is sorted or I get rid off it before the warranty expires (thankfully I extended to five years).Hi Two Guns, I hope you pick this up. I am very interested in you past situation. I am in exactly the same position. Adblue issue are now starting and have started the van build and am wondering that if this does not reslove before warranty what options do I have. Any chance of a phone call as this would be much easier than writing?
Regards,
Goodness me @Twoguns. Shocked to hear you are still suffering after all this time and when they had your van for so long and replaced pretty much everything.Hi Mate, unfortunately I’m still suffering with the same fault and I’m on just over 20000 miles.

As you’ve probably read this thread I’ve had loads changed and at most it just delays the time between reoccurrences. The last time I had the VW call out guy come to look at it back in November, he said they were aware of it and have seen lots of it and he believed that VW have a software fix that at the time was due out mid December and that he will give me a call if he saw it come through. He said they just acknowledge and record the fault now as no point sending to dealer.
We are on first name terms now as he has been the one who has come out to me over 8 times now and sent it to the dealers 4 times on a low loader so I believe he is legitimate but he can only tell me the bullshit that comes from above him.
I’m off on holidays tomorrow so will raise the fault again when I get back and see if there is any update from him.
Sorry this is not what you wanted to hear but this seems to be a common fault now.
VW would of replaced the van at the start of the fault but as I had spent nearly £10k converting it they would not cover this cost. Unfortunately even the financial Ombudsman sided with VW on this decision so I’ve been stuck with it.
