    Dufffel,

    If I was to attempt to post one my long winded answers to all of those questions in the above post, I'd be here all day.

    One thing that springs to mine, is find a local sandblasting company, who'll sand blast all of the front suspension bits, then immediately spray them with etch prime to stop them rusting as the metal is completely raw and will start to rust in hoursduring especially druing the winter. Take thm home and paint them with one or two coats of POR15. I think it is better than powder coating which can chip and then rust starts to get in again.

    Best to take all of the front suspension apart and do it all at once. Order two new silver screw on caps at the top of the strut housing. They'll most likely be tight / seized, had to resort to very delicately gunthering' mine off with an angle grinder without damaging the threads underneath. Wear heavy leather work gloves when using an angle grinder, take your time, ask me how I know ! Wear eye protection always with an angle grinder, wear eye protection a lot when working under the car to stop grit getting in your eyes.

    ok can't resist in asking more questions / extending the post Much better by phone, but we are where we are.

    Buy a decent work bench or get an old fashioned second hand desk made with a proper welded box section frame, put something under the four legs to make it higher to be at a decent standing work height. Secure it it to the wall so that it doesn't move about.

    Buy a decent wattage bench grinder with a grind stone and the wire wheel for cleaning threads of bolts.

    Buy two, yes two, of the new style alloy racing jacks, not brilliant quality, and not cheap, but lovely and comparatively light. Pay the extra for the higher load capacity just to be sure. Decent Halfords axle stands or equivalent would be good. Four, always better to have them to hand than to be caught short in the middle of a job / problem. Don't use the small £30.00 cheap jacks as the main jack for a urS6.

    Find a local nut and bolt supplier. Develop a relationship with the parts people in you local Audi dealer for the dealer only parts, or for small / unique parts that are cheap enough to buy from them.

    Buy a good quality bench vice, that will take abuse. when you ask it to do the impossible.

    Buy and use a tub of copper grease on the various threads so that things doen't rust solid and will come apart again easily in the future. Buy a second tube that you can use to prevent rust by 'painting' it onto bits with a one inch paint brush that can not be sandblasted, but you would like to protect from further rust. Use the yellow and grey ones in B&Q, as the hairs don't drop out as opposed to a no brand cheap brush. All a bit **** I know, but keeping these cars one the road properly has to be a full time obsession if you are to be able to keep going and not throw your hat at it and sell it it and 'put up with' a secondhand diesel repmobile.

    Hang out with someone else near you who is more experienced and who is doing similar work to their car so that you can see how they do it / get on, and get them to show you how you can help them with their car.

    Remind us, have you got a garage to do this work on the car. If not you'll need some sort of cheap pop up marquee to cover the car and still let you work on it. Working in the cold is doable, but working in the rain is a very hard station.

    I use a very large garden umbrella which covers the area of the car one is working on.

    One addict helping and encouraging a relative 'newbie' to join them in their addiction.

    God, this post could go on forever with me pontificating.

    The comments are in random order and follow no rhyme or reason, but they should still help, but there are numerous gaps in what you need to know to be proficient at doing and managing the maintenance of these cars.

    HTH.

        Thanks for info so far!

        Re interior, I will be taking it all out,fitting extra sound insulation and hopefully the Bose, cleaning everything and replacing anything that can't be cleaned.

        I have a second black leather interior which I will make one good one from.

        I am planning to put the leather foam from the other good passenger seat onto the drivers seat, although I will be getting someone else to do this.

        Next will be steering wheel re trim, anyone know who can do this? I want it to be as new, asked before about this but have no contact details.

        PS I do have garage but mg is in there at the most, but if I ever sell it lol I will have space for storage working etc...

        Cheers

          I am starting with the front suspension and see how I get on!

          Also, planning to do the interior, which I think wont be too bad but time consuming...

          Have lots of bits for the car and am planning a respray in volcano black and replacing the rusty wings and door/s

          I wont be doing the respray though!!!

          Any recommendations for tool essentials/garage equipment?

          I have a Halfords tool set and am planning to get something to lift the car, a torque wrench, axle stands, chocks and some scaffolding bar. I have angle grinder etc and a friendly garage that would probably help me with things like pressing out bushes etc if needed.

          Is there a proper good manual I can get for these cars, I have Haynes which is obviously no good except for basics and interior, but could do with something better.

          I plan to take the front suspension apart, replace all the bushes and do some rust protection including maybe fitting the bilstein suspension kit.

          If I haven't killed myself or the car by then I will try the rear!

          Not sure this is going to end well but I have to try!
          You might want to start with something more simple - replacing all the wear parts on the front suspension including subframe bushings is not much fun - these are the sorts of jobs that I DO pay a garage to do but I source all the parts I need first to keep the labour and down time on the car to a minimum. Change your air filter, replace the oil, replace the spark plugs, check the condition of your crankcase breather valves etc etc to get a feel for the car first - if the first job an inexperienced mechanic does is pull the front subframe without help from someone who has done it before - you might decide it's the last job you attempt yourself

          Find out what was replaced on your ignition system. Assuming they kept the OEM system and just replaced a coil or POS unit + bad wiring then the rest of it is still potentially on borrowed time. It pays to be one step ahead of the car if possible - there is a very good list on QuattroWorld of things that will fail on your AAN and strand you on the side of the road put together by Dave who has replied to a few of your posts on here. I have a box of bits in my boot ready for the when the inevitable happens and my CPS/turbo return coolant hose etc etc fail on me at an inconvenient moment.

          Personally I would still consider converting your ignition to a later and simpler TFSi based system. Even if you have spent £200 fixing whatever is wrong with the original system - on the basis that the rest of it will fail at some point it will end up costing you more than the £250 it will cost to replace the whole lot now in one easy hit with a good conversion harness and you've got peace of mind. PRJ on here will even sell you a tune that includes an adjustment to the ignition dwell time for the newer coil type.

          If you want to rip the front suspension apart then I recommend you source all the parts yourself regardless of whether you do the work yourself. I did all this about 3 years ago so can help you with lists of what you need. Personally I think the Eibach springs sit slightly high at the front compared to the rears - my theory is that these were designed for the V8 S6's which are plentiful in Germany and it sits a little higher than it should with the 5 pot. H&Rs are a good alternative and will drop it slightly more at the front. I'll post a photo of my S6 Avant sitting on Eibachs if you want to see what the ride height looks like.

            Hopefully all of the content / comments in my posts are taken in the right manner. The are just my opinions / beliefs from my own persspectives based on my expeiences to date and my limited mental abilities.

            Remember now you said you had a garage, and a V8 MG.

            You may have this in mind already, and excuse my aburptness, but if it was me I'd get rid of the MG as soon as you can - To free up the garage, funds, and the hassle and baggage of a non required / performing (for what I think you want / need ) car. It will allow you to focus on the job in hand, the C4 - urS6. A 380bhp RS2'd C4 Avant will keep you satisfied and meet most if not all of your needs, IMHO.

            As regards putting a Bose kit into a car, I thought the same and even went as far as buying the Bose kit that another member had for sale, but then I read about all of the people taking it out, and put in regular good quality stealth installations. I think I may not take it out if is was oem, and worked as intended, until I was very sure. But going to the hassle of putting all into a non oem Bose car, I'm not so sure. But I still love and have the Delta head units in my urS6s. And would have one in my S2 if I hadn't bought a Becker Mexico with blue tooth years ago.

            See what others think about the Bose ?

              I have the Gamma Bose in my 93 UrS4 and the Delta Bose in my 98 C4 A6q avant. When I first got the 93 in 1998, I thought the sound system was wonderful. When I went down to pick-up my 98 C4 avant in Seattle (it had been railed from New York), one of the quattroworld guys, Carl H., gave a ride in his 95 S6 that had had the Gamma Bose removed and replaced by a custom system with multiple Macintosh amps and Quartz speakers. It was fantastic.

              When I got the 98 C4 avant and got things operational (the battery had died enroute and I didn't have the radio code (had to get it from a dealer)), I found that the Delta Bose system was better than the Gamma Bose but not as good as the custom system. I would be happy with a Delta Bose in the 93 UrS4 but that will never happen.

              I bought a spare Delta Bose head unit when they were on close out for $25 so I am good to go for awhile.

                Thanks for the info guys, I am appreciating it all

                MG is still in garage, I might try to sell it again come new year, it is now sorned so not costing me anything at the mo!

                Did some jobs on my car yesterday, only simple ones, but actually did them which was a major achievement for me, even though the jobs were very simple:

                Fitted the new indicator to replace the (2nd) lost one! Undid the headlight and made sure it is clipped properly to the headlight this time so hopefully it wont come out this time

                Replaced the accelerator pedal as mine had fallen apart as they do

                Fitted the arm rest, really liking this option already

                Replaced the gear knob with a new one

                Checked all fluid levels under the bonnet

                Was desperate to hoover out the car, but it has been raining so much it was horrendous doing the small jobs I was doing anyway.

                Car is going for respray soon, I think I have all the parts I need and then I am looking at the interior.

                I will take lots of pictures as it goes and update.

                Mechanicals will do as I go/things fall off, I will be trying to do more myself...

                Not planning any performance things now, so will just replace like with like etc.

                I need to get the wheels refurbed, had a crazy idea to get them refurbed in white, but I think I will bottle that and go for silver

                Had the car a year, been an interesting year, but hopefully making some progress now

                Have a good Christmas and New Year All

                  OMG,


                  It has to be silver fgs.

                  8 x 18 - Mk 1 S8s

                  9 x 18 - BBS LMs reps - genuine is too dear, for me anyway.

                  or 9 x 19 - BBS LM reps or B7 RS4

                  http://12v.org/wheel_gallery/ - Have look at the various wheels on this site. Very handy for seeing what wheels look like what on a C4. Click on any of the headings at the top and it will put them in that column's order.

                  Not sure of the size of tyres to suggest on 19' rims for a C4, but search on here, or others will make suggestions.

                  Bought a set of Dunlop SP Sport Max RT 92Y Extra Load 225/40/18 - I appreciate tyres are subjective, but very pleased with them especially in the wet.

                  Good to see you're progressing, it will help keep you sane.

                    Sanity is almost intact, but I am sticking with it...

                    Re wheels that is the only thing that is defo not changing, I have the original 17" wheels and they are the best for the C4, they are awesome, right size, wide tyres and easy to clean.

                    Will most probably being staying silver though so the wife won't notice lol!!!

                    I could do with a small favour from someone:

                    If I open the boot (estate) and look down, there is a gap between the boot floor and the bumper, ie you can see the ground, I think it is missing some trim, rather than the bumper being bent, what is missing? Can someone take a photo? Not sure if I am missing a bit from inside the bumper rather than on top of it??

                            8L0862257A was dropped in favour of 8L0862257 in 1996 and 8L0862257 was dropped in favour of 8L0862257G in 1998. 8L0862257G works with radio frequency remotes.
                            Bit of an update. I've now got Dufflecoat's S6. It was bought so the missus can move out of the 80 tdi estate, there is a lot more room for the pram and all the shopping

                            It is going to be 6 months or more before I can get everything done to it so the 80 will have to do for now.

                            Im bringing this part of the thread up again as I would like to make it remote locking. There is mention of central locking pump part numbers and apparently the car has the wrong one. Im breaking a 1998/9 Cabriolet and this has a pump with 8L0 862 257 H part number.
                            Would this pump be any good and if it is what would I need to do to get it working?

                              I has been some time since I posted by reply to Dufflecoat. In the interim, I have bought a 94 S4 V8 avant that has "central locking" but no remote locking feature (no infra-red system or radio frequency system), just the key in the door or the hatch lid locks. Turn the key one way the doors open. Turn it the other way, the doors lock.

                              This means there are two contacts and two wires at each lock. The trick is to find/figure out which wires they are (I am close to that) and intercept and tap into them before the central door lock pump (in the foam box under the rear seat, between the door jamb and the battery).

                              With that done, the next trick is to find an aftermarket remote like Right Click and install it using those OE wires as the open/close triggers.

                              Here is one discussion on that: http://20v.org/remote.htm
