Hi, I'm a newbie, had my D3 for 3months and love it - except... Having a few early teething problems. The latest is that the brakes went hard. Took it to my local inde and have been told that I need a new servo, vac pump + pipe totaling £1000. No idea if this is the right cost for this work, any advice welcome. Thanks

Do you have a pic of the engine top focusing on the driver side

Hi thanks for replying, wasn't sure if I should have mad a new post. I don't unfortunately the car is with the garage. Apparently it's had the recall done on it a long time ago and it's now failed again.

Whether you need the vac pump is debatable. I guess it ensures the problem doesn’t return. They are £250 and painful to fit.
Cost it about right. £500 parts £500 labour

Many thanks Pete for your help.
I was wondering about the vacuum after reading all the posts I could but as I'm only just getting to know the car and the fact that brakes are the only thing that stops you I think I'm going for peace of mind in getting it all done.
My quote is slightly higher on parts and less on labour so ball park about right from the sounds of it. Will look to see if we can source the parts cheaper, I've found a TWS servo and a Bosch Vacuum which are both quite considerably so. The only thing I'm unsure about is if these are any good.
Again thanks for your earlier help.

The bosch pump should be ok.
TRW servo's have been know to have counterfits out there or poor (leaky) batches. So tread carefully there.

“Note that this is a gloves-off bare hands and arms job as there hardly is any space behind the engine, so be prepared to sacrifice some skin”
and
“ Expect this job to take a full day. Not really difficult. Just timetaking and painful”
These two quotes from the original post sum up this job. I can now see the merits of removing the cross over pipe.
You need twliglet arms yet the strength of an Ox
I am now celebrating with cheese and wine…
…until tomorrow when i have to go back outside and finish it off

Found this old thread when looking for information about oil in break servo.
My 06 D3 was in for a "recall"(?) for this problem in 2010 and has this new pipes with valve on.
I don't know how much parts else there was replaced.
Two weeks ago I heard this gurgling sound when breaking.
Sucked out 2 dl oil from the break servo yesterday and now everything seems to be good.
Great brakes and no problem(?).
My question is; are there need for replacing the vacuum pump, break servo and main brake cylindre?
How to figure out, in case?
And, do anyone know if the oil filling of the break servo is something that goes over years or is it "sudden"? Is it maybe the valve on the pipe that is broken or is it of course another problem - with the vacuum pump?
Very happy for quick response if anyone sees this!
Hi Finnish. I've been trying to figure out what's required to suck the oil out - perhaps you can give some guidance? It'll be a few weeks before I can get the car in for replacement parts, so I just want to help it along until then. Do you (or anyone else) have any advice please? I've not been able to find the details yet.
Thanks!

Thanks Pete. Errr.. Where do I stick it? 
I mean - where is the best (only?) place I can suck the oil out? Maybe there's a market for an after-market drain valve

I assume you are trying to drain out the servo.
You remove the vacuum pipe between the servo and vacuum pump
Using wd40 or similar and large flat blade screwdriver
Remove it at the servo end
You then usually use a white cable tie as
a dip stick and see if oil is present.
Then put the pipe and syringe in to suck out oil

I guess the whole point of the recall was to get the servo drum replaced (and the rest of the parts) and not only to remove the oil
As the engine oil collects at the bottom of the drum can't see how it effect the main brake cylinder or membrane inside the drum, however replacing these parts did make the braking feel better / less hard on the pedal. Since the design of the vacuum pump did not change it is debatable if it really needs to be replaced. However the non return valve hose got replaced/upgraded as part of Service bulletin P017.
I would therefore replace the hose, and as the supercharged Range Rover Sport servo drum / brake booster slides perfectly into place, would choose that as alternative. Bigger is better 
However upgrading the front calipers to the Brembo 6 pots REALLY improved braking.

Yeah I don't understand how the oil impacts braking in the short term, but it does seam to!
They only replace the servo if oil is inside it
Fitting the larger SC servo is part of the recall. (maybe due to availability)

This is a very intresting topic!
I also have vacuum issues: poor booster capacity on low Revs.
I also hear an ticking/rattling noice (frquency follows the Revs).
Could it be the vacuum pump that needs replacement?
Looking from the underside of the car I see a light oil leak at the vacuumpump.
Another question: Brakebleeding with the help of the IID Tool? How does this work or where can I find the info on this.
Many thanks,
