Evening people, So about 2 weeks ago my engine light and EPC light came on. Engine light began to flash and the car ran rough and juddered with little power as I pulled over to a stop. Lots of exhaust fumes came out smelling like petrol/oil but not sure. HOWEVER, today I got the car back (recovered) and it’s running just fine, drove it in a small circle etc. with none of the previous lights/issues. What could be wrong? I don’t want to part with my beauty! AA said maybe my fuel pressure sensors have gone and that my oil was overfilled upon inspection. They had the following error codes; Engine control 1 - A0F / Motronic MED 17 Status :P164E - Oil pressure control valve 1. Error Message : Electrical fault. Error static. Status :P2015 - Intake manifold flap position sensor. Error Message : Signal improbable. Error sporadic. Status :P0304 - Combustion failure cylinder 4 detected. Error Message : . Error sporadic. Status :P119A - Fuel-pressure sensor. Error Message : Faulty operation. Error static. Status :P0301 - Combustion failure cylinder 1 detected. Error Message : . Error static. Status :P130A - Cylinder shutoff. Error Message : . Error sporadic.We have arranged for a recovery of your vehicle.Engine Oil Overfilled Any help would be appropriated. I’ve attached videos of the engine when it went dodgey and the dashboard lighting up like a Christmas tree. Cheers, Euge IMG_9124.MOV IMG_9125.MOV

I changed coil packs and spark plugs but still there is misfire. Esp light came and parking brake fault but gone. Audi A3 2013 1.4tfsi 65k miles

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.

Hi there, first time posting here. I have a 2011 Audi A5 2.0 TFSI with 85k A bit of backstory.. My cars timing belt went while driving and was replaced in January. This was caused by the timing belt tensener becoming slack. After that my car has been struggling to keep constant revs when cold and ended up misfiring on a long drive. I managed to limp it to my garage where they changed the O2 sensor. The car seemed fine untill about a month ago when a wired metallic rattle started when letting off the gas. Sounds a bit like a clockwork spring being released. At first I could only hear it after turning the engine off but has now got louder. Sounds like it is coming from the left side of the engine. My car has started misfiring again and is currently undrivable as one of the cylinders isn't working. It also has a fault code saying the engine is running to rich at idle. This has gone after both repairs but returns after a few weeks. I had a fault code last year saying the car was running to lean but went after a week so haven't been to worried about that. I hardly drive my car. Probably around 1000 miles this year. Could anyone provide a bit of help. Just want to sell it now but need to get it working first

Hi everyone, I’m new to the forum so bear with me! I have this issue with my A4 (B7) 2.0t cabriolet. In normal driving conditions when warm or cold the engine seems to run fine. No knocking, loss of power, strange noises or vibrations. It seems to be running as it always has. However, when I try to get the engine to run at very high load (ie greater than 90-95% load) such as accelerating in 5th or 6th gear up a hill, the engine light flashes, there is some juddering from the engine bay and zero increase in power output. Power levels don’t seem to drop, they just don’t increase. The check engine light flashes then sometimes goes out and sometimes stays on. If I stop asking for power then the car goes back to normal. Interestingly this doesn’t happen at all in gears 1-3 and only in 4th if I plant my right foot going up hill. Ive got an OBDII reader (which I’m aware isn’t as comprehensive as VAGCOM) that gives me some basic info and lets me reset the codes. I get code P0301 - Cylinder 1 misfire detected. Throttle position 88.24% MAF air flow rate: 103.38 grams/sec Timing Advance: 8.0 deg Speed: 98kph Long term fuel % trim-Bank 1: 1.56% Engine rpm: 3173 Intake air temp: 19.0 deg C Short term fuel % trim Bank 1: 15.62% Engine coolant temp: 93.0 deg C Runtime: 00:05:38 Engine Load: 100% Fuel system status: 2) Closed loop: Using O2 sensor for fuel mix. Ive done a fair bit of googling and most of the others with the same error code had the misfire occurring at all or most of the time, not just when under heavy load. I’ve swapped the coil packs and spark plugs between cylinder 1 and 4 with no change (makes me think they’re both fine) Although I haven’t swapped for new ones yet. Any thoughts? Wondering if there’s a bit of carbon deposit partially occluding the fuel injector for cyl 1? Although I’d have thought that would cause problems at lower loads as well. For what little it’s worth I popped a bottle of Redex in with a full tank of 98-99 RON BP petrol. So far used half that tank with no change. Doesn’t seem to be getting worse at least. Thanks for the help! Matt

I am a new member in this forum. I really appreciated any helps that can given to my Audi A4 car. Recently, I found out my Audi A4 2008 car start to shake when the car is parked or stopped at the traffic lights. The shake became really bad even when I am driving it, so I took it for a professional diagnostic service. From the test report, it said the cause of shaking is because of misfire on one of the 4 cylinders, the cause of misfire is because of low compression, and I was told it would cost over thousands to repair it. I am reluctant to pay over thousands for the repair as it is a 10 years old Audi (although still drive beautifully). The other option I am thinking of is to trade in for another Audi. I want to know has anyone had the similar problem with the misfire? and realistically how much will it cost for repair? Is there a good, reliable and honest Audi specialists in Gtr Manchester area? Thank you so much if someone can advise me on this?

HI Everyone, I recently bought an Audi A6 1.8T 2001, not knowning it would have issues straight away. When starting the car, it will misfire ramdonly for the first minute or so and there will hardly be any power, then the car will seem to try as normal but does feel like its being held back a little. I bought a VAG-COM reader and used VCDS lite software to read to error codes. Please see the following codes below and suggestions where to first start to fix this issue. ------------------------------------------------------------------------------- Sunday, 10 January 2016, 11:21:07.
