Hello everyone! Here I am back with some major updates! I picked up the car from my mechanic after completing all the work mentioned earlier. The car is running great—in fact, I’ve already driven over 2,500 km with it since I bought it. There’s still a bit of uncertainty with cold starts, but aside from that, I’m really enjoying a solid and very pleasant car to drive on a daily basis. Over time, I’m noticing a few "notes" about the car, including: I replaced the tires with some high-performance (and fresh) Hankook ones, which significantly improved driving comfort. Unfortunately, I discovered that 3 out of 4 alloy wheels are bent and need to be repaired. Indeed, at around 100 km/h, there’s a strong vibration in the steering wheel, and after 3 balancing attempts, nothing has changed. Regarding the uncertain cold start, my mechanic and I first agreed to use four full tanks of diesel with the addition of Bardahl Top Diesel+. I’m currently on the fourth tank and the issue persists, so we’re going to try something stronger, like mineral oil for 2-stroke engines, to try to "unblock" and clean the Bosch pump from any accumulated sludge. If that doesn’t help, we’ll proceed with replacing the camshaft position sensor and, if necessary, overhaul the pump. Fuel consumption has finally settled into a very interesting range. In fact, I’m now getting 13 km/l (30 MPG). What can I say... I’m really happy!

Thanks! In fact I've spent 2.500 Euros so far to get a promising 2.5Tdi for another 200.000Km without any more issues than the regular oil change. Every year I've spent like 4k Euros on my old car, a Land Rover Discovery Sport 2.0 Ingenium. So... 2.5K Euros for some "peace" is quite good for me! 😁 Cheers

Hello there! Just to keep you informed about my, in fact, "mechanical restoration" of my 2.5 BDH. Two weeks ago I left my car to my mechanic's shop to do some things, like: Timing kit with water pump Front control arm kit Automatic transmission service kit Draining of all fluids and refilling with new ones Injector sealing rings In the end, the situation turned out like this: Having then replaced: Timing system Water pump Thermostat All pulleys and vibration dampers Crankshaft pulley Coolant reservoir Automatic transmission oil pan, filter, and oil Valve cover gaskets and sealing rings Alternator (only because the old one was FULL of engine oil) Glow plugs Complete front control arm kit including tie rod ends Air conditioning gas recharge Now I hope to be able to drive it again next week, as they will finally return it to me! In the meantime, some new parts came to my home, ready to be changed! Cheers! Federico

For "lower pulley" do you mean the crankshaft pulley? Thanks!

Hello there, I'm back again! Here's my first week of usage of my new C5 2.5 Tdi. Actually the car is still with me and not in the mechanic's shop due to some delays on other cars in his shop... but it will be soon there! In fact I made a "To Do List" for the mechanic just to track down all the flaws and problems the car actually has and has to be repaired or enhanced, such as: Timing belt + water pump + auxiliary belts Control arm kit Automatic transmission oil + filter kit (ZF 5HP19) Check and clean all radiators (including the transmission cooler. The transmission shifts and downshifts very poorly once operating temperature is reached. Possible issue with the transmission thermostat) EGR valve Swirl valves Excessive smoke under medium to heavy acceleration (EGR?) Check turbo and intercooler pressure and vacuum hoses Warm air from vents when climate control is off (possible issue with engine thermostat or cabin heater core) Injector sealing rings (cold start difficulty with accompanying bluish-white smoke) Install Bluetooth system in car radio (ask electrician friend) Brake pedal very hard, and brakes "stick" briefly after pedal is released. Possible brake fluid issue Power steering pump sometimes noisy. Check fluid level and replace if necessary Check rear suspension height Check and replace dual-filament rear brake light bulbs if needed Replace windshield washer pump Apart from that, she sits quite happily on the road again!

Thanks man, for sure! I think that can be the injectors... the glow plugs looks fine to me. Anyway, we can put some new glow plugs and some new injectors seals just to be careful and peaceful, no probs: I want to use this car for (minimum) 5-7 years before decommisioning, so it has to be perfect! Any advices/hints for the "BDH" engine code? Thanks! P.s. can I ask here regarding the bluetooth dongle or is it better to create a new thread? Thanks!

Hello to all! So... finally, I made it! I bought it yesterday. So, now let's set some " Year Zero". The car itself is very good but it has some flaws. The owner told me, as I wrote before, that the last oil change was 3 years ago... but the last checked oil change was SIX years ago... We got it running flawlessy and I made 140Km to get to my mechanic and start some troubleshooting. I don't think, in fact, that is an AKE, because I saw written in the "pink slip" that the engine code is "BDH". We drained all the old (very old) oil and we put: Some shell 5W-30 Audi Specific All new Mann filters Apart from that, the car last belts change was over 8 years ago ( and over 100.000Km ago) so next week we will do this works: Water pump and belts (auxiliary and main) EGR blanking Swirls blanking (got some error codes) ZF Oil, pan and filter for the Tiptronic A bluetooth dongle to install in the RNS-D Right now, my mechanic's advice is to "loose" all the old oils and liquids of the car for one week of daily use and then drain all and put all totally new. Just one strange things tends to happen sometime: at cold, the car first time cranks but not starts. Then I put again the key, crank again and it starts ( we change also the fuel filter and the battery) Here's with my beloved "Old Lady" Cheers!

Hello Steve, nice to meet "online" the man ho helped me indirectly to take a decision ( thanks to your guides in this lovely forum). If I can sell my Disco Sport during next week, I'll collect that A6 as soon as I can: the owner wrote me this morning, telling me that he wants to offer me for free an oil and filters change before collecting directly in Audi Service. The car, as far as I know, was kept always in a garage ( in fact, the car hasn't any body flaws or dents). I'll check as soon as I can the "battery drain" problem, as mentioned on one of your threads but i was in the passenger seat and the carpets doesn't seems to be humid or full with water. Again, if I can achieve to collect the A6, my next steps will be: Oil and filter trans change (ZF OEM parts) Distribution belts and water pump (Bosch or Continental parts) Full fluid change ( brakes, steering, cooling) Glowplugs (Bosch) Tyres (actually it has some good old Toyo Proxxes, but DOT 2019 and incorrect size, 215/55/17)

Hello! First of all, I'm so sorry for my bad English: as an Italian, English isn't my fist language, but I'll try my best to be understandable. I'm a 33yo italian car enthusiast that especially bought english cars ( I still have as a "relax driver" a Daimler Six LWB from 1995). I also still have a LR Discovery Sport 2.0 Ingenium that is a nightmare (please, pretty please, avoid this engines like hell!!). Bought it used in 2021 with 68k Km on it and right now has 168k Km with over 15k Euros of extraordinary maintenance on it. Two weeks ago, while searching for new windows as I'm renovating my house, I stumbled across a 2005 C5 Avant AKE Tiptronic in marvellous shape. The car owner is the shop's owner aswell. He talked to me a lot about the car. One owner from new, it has 210.000Km made in roughly 20 years and only serviced in Audi. The car, in fact, was full of Audi invoices regarding some regular maintenance (engine oil, filters and so on) and some extraordinary maintenance ( distribution made at 168.000km in 2016 or 18 I don't remember, a new torque converter in 2018 at 189.000Km, tank diesel pump and so on). Actually that C5 is not used since 2022 because the owner bought a new Volvo XC60 and he wants get rid of it for 2750 Euros. The car drives smoothly with no esitations... Could it be safe to say that could it be a good car to make 25.000Km/year doing, of course, an oil change every 10.000Km and checking all the components when needed? Thanks in advance, I'll leave some photos of the car here! Cheers Federico

Hello there! I'm Federico, 33, from Italy! I'm in search of a "new" adventure buying an A6 C5 Avant. Thanks for help in advance!
