hello. First time post - be gentle!
Like so many others on the forum, I too have a history of EGR problems. My van is a 2018 T6 2.0 102 (CXGB engine). My first problems started in Sep 2019 at 11500 miles. VW did an “EGR Flush” under warranty. THis mostly worked until June 2022 (19000 miles) when i had to get the EGR valve replaced (at an independent). I have been ok for the last 3 years when recently i had the dreaded P0401 egr insufficient flow fault at 29,000 miles. My local independent tells me the EGR is very likely clogged and needs replacing again.
I find it hard to understand why this happened again after just 10,000 miles. I should add that it is a campervan conversion and is almost exclusively long journeys although we do drive "conservatively" (low revs). The van runs well, consumption is good and i don't use oil.
VW are offering a flush at £400 or a replacement at a whooping £2,000. Based on my previous history the flush lasted nearly as long as the replacement valve. I have found some very helpful information about the VW flush on the forum (thanks) - I believe this flush is chemical based.
I have now come across hydrogen cleaning for example this company https://enginecarbonclean.com. I haven't been able to find much information about this type of cleaning - certainly not specific to the T6. Has anyone had any experience of hydrogen cleaning. Any recommended companies?
I have also heard of terraclean (chemical cleaning). Again any experiences
