Hi.
How did you check for leaks?
Some leaks may not be visible to the naked eye but can still cause issues.
Did have this issue on a 1.6 Golf TDI and couldn’t find any leaks anywhere until we used a smoke test and there was a small split in one of the intake pipes which we would never have found just by looking so may be worth eliminating that completely first.
