  1. For the last six months plus, while driving at any speed or any gear, random power losses/misfires for one or two seconds, with no pattern sometimes it does not do it for days and sometimes does it three times in a fourteen mile journey, with rev counter dropping and returning to normal again. Sometimes when accelerating from a stand still at a traffic light when I move off, the car seems to do what I can only describe as a huge misfire, I feel a large thud from the engine and the vehicle jerks forward violently then acts normal again so I can drive. Vehicle has had a minor Audi service March 2017b (also full Audi service history). 29thApril I fitted a brand new original Audi original part fuel filter. It seemed to improve things but.... I still see the random power loss/miss fires stutter. Straight after fuel filter change vehicle put on a computer, codes came up P0087 and P1093. (Re computer codes picture attached)Reference code P0087 I googled results; https://www.obd-codes.com/p0087Potential causes of a P0087 trouble code may include: Weak fuel pump, clogged filter or screen, restricted fuel supply line Faulty fuel pump driver module Faulty fuel pressure sensor.Reference code P1093; http://wiki.ross-tech.com/wiki/index.php/17501/P1093/004243P1093 - Bank 1; Fuel Measuring System 2: MalfunctionPossible SymptomsPower LossMisfire(s)StallingPossible CausesFuel Pressure insufficient/exceed/fluctuatingFuel Pump (High Pressure System) faultyFuel Pressure Regulator Valve (N276) faultyPossible SolutionsCheck Fuel Pressure (on FSI engines High and Low Fuel Pressure System)Check Fuel Pump (High Pressure System)Check Fuel Pressure Regulator Valve (N276)Check Fuel Filter and Filter in Fuel Pump CasingSpecial NotesWhen found in 2.0l TFSI<http://wiki.ross-tech.com/wiki/index.php/2.0l_TFSI_(AXX/BGB/BPJ/BPY/BWA)>: * Check Fuel Pressure<http://wiki.ross-tech.com/wiki/index.php/2.0l_TFSI_(AXX/BGB/BPJ/BPY/BWA)#Checking_Fuel_Pressure> * Check TSB/TPI 2008753 (Rest of World), incompatibility between Fuel Pressure Regulator Valve (N276) and ECU software. * When found in conjunction with Misfires and Lean fault codes, check RVUTB: 01-09-03 or 2018919 (NAR only) 2.0T (BPY), for updated Crankcase Breather Valve * If the breather valve is faulty, full engine vacuum is typically found when removing the oil cap at idleMaybe possibly need a new breather valve, high pressure fuel pump/cam follower, or fuel pressure sensor. I've booked my vehicle to go to Audi specialist Les Paul's for first time and I hope they can fix issue as quick as possible.
  2. Hi there, I have this weird problem with my car, an Audi A6 allroad from 2015 with the 3.0 tdi 218 CRTE engine. I bought the car in Nov 2018 from Germany and for 2 years I had absolutely no issue. First issue (oil cooler leak) The first problem that appeared was a leak in the gasket of the top oil cooler of the engine. The issue looked like missing coolant and was solved temporarily with more water and then in the service by replacing the the gasket and cleaning the oil cooler. Back then the error codes were shown in the dashboard (high temperature warning) as well and once the oil cooler gasket was replaced the error disappeared. 2'n issue (engine complete stall) After 8 km (after I took it from the service) I was in town, stopped to a red light and the motor stalled. When it did this I was in Sport Mode and when I accelerated to start the vehicle the engine rev went very high even though I did not push the pedal to the ground and simply stopped. I could not restart the car from that point. I called a trailing service and got it to the auto service. The first issue they discovered was that the Denso starter was bust as both wires were shut probably due to the fact that the motor was stalled and the starter could not move it. You can see the damage below (attached). We changed this part with a new one and the guys tried to move the motor manually to see if there was any issue with the motor itself. Given the fact that the movement was not quite ok they decided to open the motor to see if there was any damage inside. When they did this they found metal bits in the oil pan that is under the motor as you can see below (attached). These small metallic parts came from the bearings (I hope it is the correct term for the parts that look like a circle split in 2) of the crankshaft and they basically got stuck on the crankshaft and even shifted in their place and started to turn with the crankshaft itself. Here are those parts after they were taken out (attached). 2'n issue repairs At this point the following measures were taken: 1. The crankshaft was measured to make sure it is straight, the bearing surface was rectified and new bearings were installed according to the new specs in specialized shop. 2. A new oil cooler, oil pump, gaskets and a complete oil change was done The motor has been reassembled and since the front part with the vehicle was disassembled, the tempomat needed a recalibration. This can only be done in Audi service so my service took the car there for recalibration. I asked them for a motor diagnosis to see if there was any error code or something that they ca see and my service cannot see with their computer. The diagnosis did not show anything at all. When all this was done I took the car for driving and did around 300 km in various regimes: city, highway in both normal and sport mode. The engine seemed to have a nice sound, performed really well without any issue. Since the cold season came when temps went below 0 the engine had a little lateral shake at cold start which was barely noticeable. This would disappear after 2-3 minutes and would never appear back up until the next cold start. I had previously a 2.0 TFSI A3 which had the same behavior for as long as I had the car (11 years) and nothing happened. 2'rd issue (engine starts shaking vigorously) Yesterday I went again to a longer trip, started the car and after 30 km it started to shake more vigorously up to the point where you can really feel it. I stopped the car on the side and shifted to N. The shake continued and some weird noise was also hearing like someone would knock with his finger in a plastic piece. I took the car back to the service on a trailer and we discussed the symptoms above and 2 issues were checked: whether there is any error code in the computer and there is none and the oil filter which again had some small pieces of metal in it, so I presume the same issue happened. The problem is they did not say what was the cause when it first happened either and they just presumed there is an issue with either an oil pressure sensor or the oil pump. I suppose that any malfunction of either these would have triggered a computer error. They changed the first time both the pump and the pressure sensor, yet the problem remains since we do not have any clue what is causing this. I mentioned I have the car for a little over 2 years, I bought it from Germany when it had 1450k and now it has 170k. The no of km is fine since it has all the service checks and changes done in an Audi service in Hamburg and it had only 1 owner prior to myself. Also the service of the car in these 2 years was done according to the manual at every 15k km. I searched the forums for similar problems and I could not find anything. I hope someone could guide us or at least give a hint on what to check. I can provide pretty much any kind of data available with the tester or any other info as I have access to the service and I know them really well. At this point the service recommends a new engine (from a donor car) that would basically be bought by me and installed by them. They also said they can buy a new crankshaft and bushings and install it but the guy with whom I spoke said it will do the same after a few hundred of km. Also I am little bit reluctant that they will make the repairs with all due diligence. My questions now are: 1. What might be the cause of the first stall given the work done at the oil cooler? Some other people with whom I discussed said it might be related to the turbine eating oil. The turbo was not checked since nobody came with this idea on their end. 2. What might have caused the 2'nd stall since everything was changed and repaired? 3. The guy said he also talked to some Audi service consultant and reportedly this guy said these engines (3.0 CRTE 218) have some construction issues that generate these problems. I find it hard to believe an engine with this issue would make it to 170k km and only break when someone starts changing a gasket. Also I would have found complains about similar issues on the internet with people failing these engines from 2015 on, yet I could not find anyone with a story like mine. Is this an engine with common such faults?
  3. Hi Everyone ! I have bought an Audi A3 8p 2L TDI (170 HP) STOCK 2005 with 120k miles, engine code BMN. After a month of using it with no problems I go a map for 200 HP installed. However, the next morning after the map was installed the car had problems starting, however, it started. After that the car would randomly cut out while town driving or very soon after starting the car. Although if I made it to the motorway I would have no problems. Sometimes when it cuts out it wouldn't start up again until I have waited for around 10-20 mins then it would start with no problem or some times it wouldn't start for a day or two and then it would start after many attempts. To the extent of my testing once I have driven it for about 20 mins it wouldn't cut out as long as I don't turn the car off and let it sit for around half a day. If I let it sit for 1, 2 or even 3 hours it normally would start maybe with a bit of a difficulty and wouldn't cut out. I have been to the mechanic 3 times. First time they said they got an error code saying the common rail is faulty. So they replaced it. no change.... then I had service due, so I got all the filters etc replaced. They noticed there was oil in the fuel pump system, so they changed the fuel filer twice to clean it a little bit.... No change. Then at the third visit they said that the low pressure fuel pump is not working and that the seal around the high pressure fuel pump is bad and that's why there was oil residue in the fuel system. So they fixed that and changed the fuel filter again.... no change. At this point I have spent around 700GBP and nothing has changed. I have read articles with similar problems and in few they refer to relays and the ECU. Does anyone have any ideas where I should start looking ? Or what I should tell the mechanic to look at ? Also, should I maybe find a different mechanic ;P Thank you and any comments would be much appreciated !!!
  4. Hoping someone might be able to shed some light on this issue: 2008 A6 Avant 2.7 TDI Le Mans, been driving perfectly, no issues at all. Got in the car this morning and every time I let the clutch out the engine stalls. No, not my bad driving.... It's not mechanical - the gears change easily and you can feel the clutch bite, but as it bites, the engine shuts down, just like it's being turned off. If you're really careful you can keep the car moving just by slipping the clutch a little, but as soon as it bites properly the engine just shuts down. The engine starts and revs freely. No fault codes show up and no warning lights on. No funny noises or sudden jerk, just a straightforward engine shut down. If anyone could shed some light on this I'd be very grateful. Thanks!
