About six months ago my shocks started leaking, dropped dead on my rs4 b7 .As you might be aware there is a known problem with the drc system and shocks on the b7 rs4.As the audi dealership in the city I live does not have the tool to re-pressurise the drc system I took the car to a service that said they would do it and change the shock internals with some "upgraded ones" .I asked them up front if they think they can do the job and not screw up, as I would not want to have problems with the suspension afterward. They charged me 1200 euro for the work the`ve done to the suspension and some misc parts(bolts and some bushings). As I was waiting for the suspension to be complete I also told them the gearbox had some problems changing into 3rd, when changing really fast and brutal I would hear a metal on metal sound but very short duration , not something that would prevent me from using third or something that made shifts hard, just something that I would ocassionaly hear when changing from 2nd to 3rd and bugged the hell out of me . It was obviously a synchro which was worn . The shop mechanic told me he can manage it, and after further reassuring by the owner that they`d opened other gearboxes and put them back together with no problems I told them that I was going to pay the price they asked but only if they thought they could manage it. As the gearbox was coming down off the car it was only obvious that I would upgrade the clutch which was not old or very badly worn but not in great shape either.... Again I asked them If they thought they could manage to get the parts needed . So they brought me a clutch disc which to me looked kinda flymsy compared to the stock one but they reassured me it would do the job and not be too hard on town driving.
So after 4 months of waiting and calling at least 4-5 times a week I go to collect my car. Once I get there , the car was still being worked on , mounting the exhaust so not having anything to do I take a look at the gearbox mount and front cradle (dunno if this is the correct word, I am reffering to the ansamble that holds together the front end, something that you have to un-bolt to have clearance to get the geabox down) and I see some very odd looking bolts, nuts and also a wire sticking out.... Upon closer inspection and questioning of the mechanic that was working on the car I found out the bolts where whatever they found in the shop, my original ones gone missing and the wire sticking out was the loom to the wideband lambda sensor on the right bank of cylinders. I went bonkers and the manager told me that they would change the bolts on theyre own expense but the parts would take 4 days to get there , of course it was on theyre own expense , It was them not me who lost the original bolts. So after another week I go to the shop collect my car (with new bolts, new lambda sensor, new 3rd gear synchro and one of the 2 sprockets which make up the 3rd gear ,new shocks and also new clutch and pressure plate). Went out with one of the mechanics for a test drive, the gearbox wasn`t making any funny noises, 2nd to 3rd gear change was going smooth as new, the suspension was firm and kinda annoying but something I could live with and the clutch was kinda hard to launch slowly and arround town but again something I decided I could live with. After completing the test drive I took a drive to my home city about 250 km away , and after 35 km of interstate driving at 160km/h the gearbox started coming out of gear, it would simply come slowly out of any gear as I accelerated, no noise no clunks no nothing , it was nothing spectacular but I knew something was wrong so i called a trailer and got the car back to the shop. They opened the gearbox and blamed a security clip (part that keeps gears in place on shafts) shearing off.Hearing that I went straight to the shop and demanded they show me the clip and the place it shouldve been .Then they said the sprocket they replaced had suffered failure, so I wanted to take a look at that also and what I found was a synchro going completely bust and also one of the 2 sprockets making up 3rd gear had suffered failure in a very odd way which to my shame I don`t have the vocabulary to explain (maybe If I can find some pictures of gears I could). Very weird failure to which they had no conclusion. So there goes another 2 weeks of waiting for some other parts, ordering the wrong parts, and another 2 weeks to get the gearbox back together. After 6 months they had finaly managed to finish the damned car .
Now I was taking it easy as to not break something again and let all the parts settle and gearbox to adapt to new oil (after consultation with the shop). So one night I would shift from 2nd to 3rd and I would see a lof of white smoke behind me, which was obviously not good , so I lay off the throttle and try to take it out of gear. Only that I wasnt able to , not without accelerating a little so the engine revs would not brake the car (engine brake) . I come to a full stop and the car would have a lot of problems going into first , the clutch pedal being very soft. Sure enough it was the clutch disc they installed which had severed and had taken the flywheel and clutch plate with it. I then take the car into the dealers and they take the gearbox down and I get a chance to take these pictures, they also tell me the suspension is shot and the gearbox has some very interesting markings which were obviously the work of some un skilled mechanic trying to pry it apart from the engine.
The last picture is of a bolt they changed from the right exhaus mainfold flange as they destroyed the original one....
Now I`ve got to re-do the clutch ,flywheel, suspension all over again and I don`t think I`m the one who`s going to pay for it all.
