Having read a few posts about this I thought I’d have a look at mine today.
Was quite gunked up so used Brake Cleaner and a Rag to clean it up.
Very easy job to do and my Cup of Tea hadn’t gone cold by the time I was back in the house 🤣🤣🤣

Here’s the before and after pics

I usually clean it every 6 months when oil is changed  Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"
New Defender D300 90
1974 Series 3 Lightweight = "Millie"
My preferred specialist: www.glenrands.co.uk

It’s such an easy job I’ll be doing the same myself 👍

I have removed and cleaned what I thought were the Maf sensors on my 2007 TDV8 in the past but they don't look like the one in your pictures. Is there another location, the ones I cleaned are on the plenum in front of the 2 main intercooler hoses? Mine looks like this in the picture and HS2 in the diagram
