cheers matey
 
now the manifolds are off and ready for a clean and inspection
but
what next?
new complete ones from TPS 1200
repair kits off ebay 60 ish
and
how far do i go with the cleaning?
egr valve system?
intercoolers?
all relevant pipe work?
gosh im not sure


right im looking at these flap rods
there plastic and metal
the plastic part runs in a plastic bush (bad design)
im thinking of a bushing the bushes idea (maybe a bad idea im not sure)
i was going to buy a repair kit off ebay first to see how much play there is in new ones
im going to inspect further first as it looks like they are more worn near the end where the lever fits on the ball part
TPS sell the end bush and ball rod part Nothing else
so
any ideas guys ???

Post a link of the flap rods you refer to. I bought some for my A8 V8 petrol and they were one piece milled aluminium.

These ones although for a petrol I think are available for diesels:

I would check for operation first, I think they are either connected or not. Mine were snapped and need replacing hence me buying new ones.

What's the reason to clean the inter-cooler? is it very dirty or has lots of oil residue in it?

My advice to clean and fix or improve what you have before thinking about spending big on brand new manifolds. Just make sure everything functions as they are meant to.

You are talking totally different thing here, diesel manifolds are nothing like petrol, just for start petrol have 1 and diesel have 2 separate one for each bank and the function and operation of flaps is different as well.

And as a true Yorkshireman you'll still not be happy :ROFL:


Well done mate, it's always satisfying when you achieve your aims for minimal cost. I was quoted 1200 for a replacement headlight for my S8, a good mate of mine found the wiring fault and fixed it for free +++
