Boot opening

[crichten]

Hey guys,
If you hadn't worked out already im slowly getting the hang of my splexy audi A4.
Just a pondry but when I click the boot open button the boot pops and unlocks however it doesnt open.

Is this the way it is supposed to work or is there a way I can get the boot to open properlly.

Thanks guys

Chris

im sure its meant to just pop the lock and you have to lift it up

it was the same on my allroad and a4

Yep the boot does not open fully on the Avant,I think on the saloon the lid flips open though.

Be warned- whatever you do, do not leave the keys lying on the boot shelf and shut the boot as the doors will all lock and you will be locked out!

My saloon doesn't pop all the way up, it just unlocks and opens and I have to lift it?! I would love it to go all the way up, I've had a Merc 220CDI for the past week and it does it and it's great!

Can anyone else confirm whether the boot totally opens or not, and, if so, what could be buggered on mine to make it not do that?

[tonyrampanttige]

my cab doesn't, bit of a pain really

[benjie]

I know, compared to my MkIV it's great to be able to just lift the boot with an elbow when carrying heavy stuff - but having it open properly would be better.

[crichten]

yeah,
Anyone got any idea how the other cars do this? Maybe we can work out how it works and just retro-fit it.

Looks like a popular idea.

[Lateknight]

You should be able to convert. (only saloon)
You'll need different boot hinges, and gas struts.

Don't quote me on this but I think it was factory option pr.4E5.

[crichten]

Hmm anyone got a part list to work out what these are?

Hi,if you look in the handbook,it looks to be an option,as there is an additional switch by the sensor/tow switches in the drivers door pocket area to lift the boot lid.:beerchug:

[kodkod.84]

Ahh OK thought it was a standard feature on the saloons- I've only ever had Avants and the button just opens the boot to the latch on these.

However the B8 saloon loan car I had flipped the boot all the way up (looked pretty cool actually) hence why I thought the B6/B7 would be the same as the lid is pretty lightweight.

[crichten]

Any ideas on how this could be achieved? Surely if it's possible on the newer ones and there isn't much structural diffrence it could be done?

[benjie]

I did a quick search last night and someone on tyresmoke.net mentioned a £30 spring that does it? But then the thread stopped abruptly, so I don't know if anyone ever managed it!

[benjie]

By the way, here's (http://www.tyresmoke.net/forum/audi-a4-s4-cabrio/62889-auto-boot-opening-retrofit.html) the thread I read.

[crichten]

Hmm well their site at least gives an idea of a price which I would pay £30 for that isn't bad :-)

[benjie]

Yeah, I know. Looking at my (saloon) boot though, I can't see anywhere a big spring could go?!

[crichten]

Logically i think it would be a beefed up hydraulic thing that opens it once u lift.
So standard but stonger

[benjie]

There are uprated springs on the workshop manual which are described as "For vehicles with spoiler," but that's it. It seems to not have been a feature on B6's but I wonder if it were an option on B7's?

[crichten]

Would a stocklist for the B7 cover that then?

[benjie]

No, there's only one part listed for the boot lifter on the B7. I am wondering now whether the lifter from another Audi (similar year A6?) with a larger overall boot lid would fit and work? Or, perhaps 2x the bonnet lifters? They have to support/assist with the lift of, a lot of weight?

[benjie]

The B6/7 bonnet lifters are identical in part no's apart from the 8E0 and 8H0 starting and the B7 has 'A' at the end. The B6/7 boot lifters have different p/n's, but with 5 digits the same in the middle, so I suspect they're very similar - apart from the B7 one being €10 more expensive!

The same age A6 boot lifter has the same part number as the B6 boot lifter.

The actual hinge that lifts the boot seems more built up on the back of the A6 - did this have full opening of the boot?

[crichten]

I had a look at my car and I would think that the relevant part would actually be the hydraulic piston as this is what opens the boot once you get it past the certain point.
So what you need is something to get it to that point, so either a more powerful piston or something to assist the piston to that point.
The hinge shouldnt have too much input on it i dont think.

[Issac Hunt]

You cant fit bonnet lifters - they are too long and the auto boot opening (on the saloon) is not done by just the hydraulic rams.

You need new boot hinges and a spring for each side. This will lift the bootlid when popped with the button on the remote or the button on the boot is pressed.

The reason for the new hinges is that your original hinges DO NOT have the mounting points for the springs. Its the springs that do the work.

The hydraulic rams are differnet part numbers as well so you should also change these. The length/external size of them is the same, its the internals that are differnet.

Changing just the rams WILL not lift the bootlid. Yes the rams do lift the boot once your past a certain point - but to get to that point you need the spring on either side.

[Lateknight]

The B7 A4 has this as an option - factory option 4E5 (does not appear to have been offered on the B6 model)

Boot hinges are the same on B6 as B7 without boot opening.
(Parts 8E5 827 301G & 302G)

Boot hinges are different on B7 with boot opening
(Parts 8E5 827 301 H & 302 H)
These probably have a mount for the additional spring to go on.
(spring part number 4F5 827 665 A x2)


Gas struts;
B6 standard (part 4B5 827 552 G)
B6 w/spoiler (part 8E5 827 552 B)
B7 option 4E0 *no auto lift* (part 8E5 827 552 J)
B7 option 4E5 *with autolift* (part 8E5 827 552 K)

Ideally you need the hinges and the springs at the very least. Maybe the gas struts, depending on the difference between B6 & B7 boot lid weight.

[crichten]

I asked at Audi Hitchin, they weren't very sure but we spent a bit of time going through it and we came up with the same results as above.
They said the hinge was the same but gas struts diffrent and additional spring on both sides. We didnt see the diffrence on the schematics for the diffrent hinges though.
Now we know is anyone gonna try it?
I might have a go if money allows.

[benjie]

You got any prices/part numbers?

[Issac Hunt]

Hinges are £30 each but probably come unpainted. Gas dampers are £25 each and the springs about a fiver. (+VAT of course)
