    Thats a bit of a pain. You should be able to get a hex/allen key into the inner bit to get turn on it, but it's odd that it's got stuck halfway out.

    If you can't get it out, then you could use a dremel cut the head off, the use a grip wrench to wind the remainder out?

    Are they the only bolts holding the sump on now? As the weight of the sump could be hindering you getting them undone..? I would have started with the hardest ones first as they are a *****!

    I've tried with an Allen key and its done the same and rounded off, I did undo the most awkward ones to get at first, there is no weight on the bolt, all I can think is the sump has been off before and the bolt has been cross threaded when put back in, I've had to admitt defeat for today I've put everything back together put a new filter on and new oil in, looks like I'm going to have to cut the bolt head off as welly suggested I'm just a bit concerned about getting the rest of the bolt out afterwards

    you could try Irwin Bolt Extractors Bolt Extractors - Screw & Bolt Extractors - Tools - IRWIN TOOLS

    I've used them quite successfully on many a troublesome bolt, got the set for one particular job and have used them quite a few times since. they do trash the bolt but generally if its that rounded you will be replacing it anyway

    If there is 5mm of thread showing, could you cut the head off of the bolt and use a nut when you put it back together?

    not a perfect fix, but it might help

    It sound like you'll have to drill it and use and Easi Out. Is it one of the bolt that's easily accessible with a drill bit?

    If I can't undo it with a 3/8" ratchet and socket I don't fancy my chances of drilling it and removing with an easy out, easy outs are very hard and break quite easy, I've ordered a bolt extractor set just waiting on it coming, if that doesn't work then I will drill it out and re tap it, it's one of the bolts at the crank pulley end of the engine so I should get in there with a drill, I've put the car back together for now and she's running fine with no oil leaks

    Well I started this after work today and want to do it al tomorrow, got all the parts needed. Getting to the 10mm bolts are no problem, the 16mm near the power steering pipe is seized solid! Also that pipe does not move out the way! Any advice please? The bolt is very slightly rounded off too. Not a good start!

    if i remember correctly there was a wee bracket holding the power steering pipe to the block, although mine just fell off :S
    after that fell off it moved out of the way enough, had to be kinda rough with it though to get it out the way.
    hope that helps

    I used a 1/2" breaker bar and 6 point socket to crack the bolts off and then undid them with a spanner, 6 point socket will grip the bolt better if its slightly rounded off, you could also try warming the bolt head with a small gas torch this might help also

    Thanks for the advice. I had already removed the bracket for the pas. In the end I got a good 5/8" socket it on as the fitted better than a 16mm in the end. The pickup was really clean anyway but all has been replaced and looks like no leaks after 25 miles of driving. Car has done 104k. Was on long life up to 80k and then oil changed at 90k then 95k and then 100k.

    1/4 ratchet with a wobble extension was a godsend when doing this. Trip to Halfords? ;)

    Just back from Belfast Audi to pick up the parts i ordered for this. Prices are as follows.
    Suction pipe (06A115251) 9.18
    O-Ring 3.75
    Sealant 17.90
    They ordered in 06B115251 which is too short, correct part should be in tomorrow, so hopefully by the weekend this should be done.
    Just wish i had a pit or a 4 poster!

    Quick bump, the part number on the first page for the OPP is incorrect by one digit. It should be 06A-115-251. Otherwise you'll end up with a very short, B5 A4 unit... like the one sat on my desk currently :(:(

    Paul, sorry to be a PITA - do you recommend using an engine flush while doing all this? I've got all the above, new oil pickup pipe, o ring, will clean the sump, new oil... seems madness to miss out a stage if you guys recommend it!

    Cheers as per.

    I've used one in the past and on previous engines. Didn't do any harm.

    you can use a 5mm allen key on the inside of the bolt...

    You could also try something like this...
    http://www.amazon.co.uk/Irwin-Bolt-Grip-Remover-Expansion/dp/B000QW6K8I

    Depends where the bolt is I guess...

    The bolt head and Allen key rounded off? Maybe give an Irwin bolt extractor a bash. I had the a problem at the end nipping them back up with the torque wrench one snapped off... Finished it off by feel to save any more it appears leak free so I'll wait for the weather to pick up and drop it again. Just hope it comes out I normally use new bolts but decided not to for some reason!

    I'm hoping to do tip and front mounted intercooler in the next few months and from research the Badger5 tip is the one to have! Fmic I fancy the Wagner one purely based on the fact it looks pretty stealthy and retains the fogs. Someone on here had one and it just looked well put together and easy to fit I'm not sure how it fares performance wise against others but I'm not aiming for silly power as of yet so figure it will be better then the side mounts. The welly cooler seems well regarded though for the price of it.

    What torque settings are required for these bolts? Obviously the three bigger bolts will be set to a higher torque as well?

    Sorry dude... didn't notice this one...

    Not a massive fan of engine flush tbh... its a personal thing, just not keen on the idea of it... never used it personally either so couldn't base my dislike on experience either... just something that never appealed..

    Don't worry chap, decided against it. Either you or someone else said in another thread "would you be happy with putting something around your engine, rather than oil that's been in it for 90k+". Fair point!

    ive always been told never to use engine flush in petrol turbo engines and seen a bmw 320d over run(run off its own oil with no control or limit to the revs) when an engine flush was used.

    i had the sump off my car at the weekend and have a good 80% left of the sealant, anyone need some?

    Tried removing my sump today, got all the bolts out but the sealant is working as a glue to hold it in place.

    Any suggestions how to easily remove the sump without damaging it?
