You guys have any tips on how to access the back lower flange bolt to remove the EGR pipe. I thought I could get to it from below but its blocked by an electrical connection which I can just about reach with my finger tips from underneath the car but if I can release it. Sure there must be some 'trick' or technique' that you use?

I did it a few weeks back.

I had to remove some sort of part/bracket on the right hand side first - its a couple of inches in front of it on the right then:

From the top I used a very small ratchet with a 2 inch extension, bit holder and hex bit. FL2 HSE Auto Galway Green

FL1 HSE TD4 Manual Black - Gone.

Thanks sir! Indeed there is a bracket as you describe.......could not see obviously how it was fixed. Will look more closely and tackle the job this way  2010 FL2 TD4 GS

Remember that well, and the sodding electrical connector. I can't remember, but I think I put an allen key on it long ways in and then managed to get pliers or mole grips on it just and luckily it moved it enough. I never put the pipe back on, just bought another blanking plate and bolted that down.

Got a feeling I got it from underneath, removed the wheel arch cover maybe ?

I know that this is an old thread, but upon replacing my glowplugs today, I found that if the battery box is removed, the electrical connector obscuring the lower bolt on the egr pipe can be released with a long thin flat blade screwdriverand removed. Access to the bolt, in my case 10mm hex head ( I presume it has been off prior to my ownership and the allen key bolts lost and replaced ), was easy with a 3/8 drive socket on a couple of 6" extensions. No wobble joint needed. Hope this helps others.
