Hi Irishladdie
Your in luck
I have just had the EGR tube and a flush of the system carried out at by the AA
My van in 2018, with 12,000 miles on the clock.
After a 350 mile drive and some local one hour drives the Engine management light came on, call VW Assist who sent out an AA patrol.
AA man reset the engine management light, bu5 said it would come back on (which the engine management light did come back on
However the first AA man said that the AA have been supplied with machines to flush the build up of exhaust sludge from the system! He asked is I wanted to get it fixed whilst I was at the campsite.
Obviously I accepted his offer, several days later ( after Bank holiday) another AA patrol attended my vehicle, he had a machine with him, long story short, the existing EGR pipe was removed the EGR valve was fitted with a device to hold it open, the machine was connected to the engine and a valve was connected to my vans exhaust, the AA man added a chemical to two 10L water drums, which were attached to the machine. My van was started, the machine was started and the flush process commenced.
The AA man went to his van, got a band new “modified “ EGR pipe
The modified (brand new) pipe has a slot in the top of the tube, the old pipe has two holes in the end.
He also pulled out several old type design, used but cleaned up, which presumably they fit at the road side when the machine is not available and VW do not authorise the modified EGR pipe to be fitted.
On inspection, the old EGR pipe has quite a lot of soft black tar in the end where the holes were, the holes were partially blocked by the black gunk that was residing in the tube, which causes the sensor to register low flow rate and throw up the engine management light.
Whilst the machine carried out its job, flushing the EGR system, I spoke the AA man.
Who told me that the EGR low flow is a very common issue particularly on T6 vans, VW had recognised the “design fault” and had re-engineered the EGR pipe to change the design and prevent the issue.
VW have provided the AA with these machines and the modified VW EGR tube, so they can carry out the mod at the road side, saving on breakdown and recovery costs.
The AA man told me that he as carrying out the work on behalf of VW ( and VW assist) the work is authorised by VW and is fully warranted by VW,
VW have widley acknowledged the issue and therefore provide the parts and equipment to the AA so they can carry ou5 the remedial works. The work will be registered by VW assist, presumably updating my vehicle records to show the updated EGR pipe has been supplied and fitted.
The whole process, including me chatting to the AA man (so slowing him up) took about an hour ! The part, IMO would be £20, the 2 litres of chemical would be pence!
IMO, the dealer is having your pants down
VW are aware of the issue with the EGR pipe on the T6
My van is still in warranty, however, May I suggest you either contact VW assist if you are a member, if you are not a member, suggest you join, call vw assist and have a discussion regarding the above and having the remedial work carried out, (you may need to drive a few miles from your home to ensure the costs of recovery etc warrant the cost of VW assist authorising the work)
I have photos of the original EGR tube, the new modified design and the machine , chemical etc that was used by the AA
I will post them in this thread for all to see.
