My 2017 T6 went for mot yesterday, it passed but I opened the bonnet after returning home and noticed a great deal of rust on what I think is the EGR valve. I don't remember it being like that last time I checked my engine. My T6 is a 2017 model, Im sure I would have noticed the rust before now, it's really bad. See pictures. What do you people think, does it look like it's been changed at some point? The EGR valve looks like it's been under water for year's, is this normal. Would appreciate any thoughts. Thanks Rob
