Hi, This is my first post on here but I was hoping someone could help me with a couple of issues. 1. I was driving long distance and about 90 mins in I received a red error saying "Drive System: system fault! Safely stop vehicle". I managed to pull over at a garage where a mechanic kindly plugged in a diagnostic but it showed no issues. I am still getting the error system every time I turn on the car though. And it drives as normal. No issues at all. It was spilling rain so I do wonder if a sensor got damp somehow. But I can't figure it out. 2. A long standing issue, the MMI randomly pops up and down every 2nd or 3rd time I start the car. Sometimes the radio won't engage when this happens. About the rest of the time, it works perfectly. 3. Final issue I'm having, the rear wiper fluid no longer pumps out water. I wonder if it's a blockage or just a faulty pump. Anyway, the first issue is the main one. Has anyone experienced this before and it is a simple reset fix? Thanks.

First off, apologies for the looooong post. I have spent approx 30 hours researching this and have found masses of conflicting threads posts and resolutions hence why I am now posting my own thread after getting seemingly nowhere. I have added my full auto scan, with Advanced ID and the Log I took yesterday as attachments to this post. Backstory: I purchased a 2007 A3 Sport with BMN PD170 lump back in March after my PD130 MK4 GOlf was written off. Other than a few niggling issues that were easily resolved (passenger door mech, ignition switch, oil level sensor, brake pad sensor etc) the car was faultless and drove perfectly. No smoke, no drivetrain issues, no electrical gremlins. It was perfect. Issues: Then, in late April, as the weather started getting warmer, air temps above 15/16 degrees C, the car starts to hesitate between 1400 & 2000 rpm. Once you've passed 2krpm, it's fine and pulls hard. Once the car is warmed up, it generally does not happen. Researching this issue there seems to be a lot of disagreement on any forum over what the problem is. Some people swear it's the DPF, others the MAF, others the EGR valve, others say it's the EGR cooler and some claim it's the DPF pressure sensor. Approx a week after the hesitation first started I got an EML. VCDS showed it was a lambda sensor issue. No problem, several hours of research later (it transpires the BMN uses an NTK sensor, not a Bocsh unit like every other VAG ever made?!?) and I got a new one fitted in under 40 minutes. Took it for a drive and no more hesitation. I put this down to the faulty o2 sensor preventing a DPF regen as its was only reading a static value. For the next couple of days, the car drove faultless again. About 3 days later, the hesitation returns (turns out the ambient temperature had been a little cooler). Logging the o2 sensor, I confirmed that it was working as it was reading the AFR values and no more error codes have been logged in the 3.5 months for the o2 sensor. At this point, the hesitation has become more of a lurching or kangarooing, again, only between 1400-2000 rpm. I have also done the following in an attempt to remedy the issue: Cleaned the MAF with electrical contact cleaner - Did not resolve the issue Cleaned the egr valve & ASV (this was horrendous inside) - Did not resolve the issue, though it was better yesterday Checked the intake connections - nothing loose or unconnected Verified the boost specified vs actual - at all measured rpm's the spec/actual are almost identical, especially in the trouble range of 1400-2000. This would rule out a boost leak as is common. Measured the MAF readings - approx 200mg/str at idle and rise to approx 450 at 2-2500 rpm - I'm not sure if this is right or not but I have had MAF issues on my old PD130 and it was noticeable through the entire rev range as a considerable lack of power - this is not happening here as I have loads of power after 2krpm. Full fluid and filter service with new fuel hoses from the filter to the hardlines to the cylinder head (perished). Logged the EGR duty, In addition to the above, I have also taken logs of the DPF and this is where I start to scratch my head as I'm just not sure what is going on here. The Particle Filter - Load Coefficient: this was at 0 for approx half of the log session, then jumped immediately to 20% and didn't budge. The Particle Filter - Carbon Mass: reads 22.23 for the entire duration of the log (20 minutes) The Carbon Mass - Learned Value: this was at -7.9 for the entire drive/log session. Would the above be indicative of the DPF differential pressure sensor being problematic? I did look at it yesterday, and it appears someone has been in there before me as the retaining bolt is missing. I've not checked to see if it's a genuine or non-genuine item, but if the above readings are symptomatic of the DPF pressure sensor, then my assumption would be that it was never adapted, or that is a cheap crap one that has failed? Does this sound right? The only error code I get is the one below: 008194 - Particulate Trap Bank 1 P2002 - 006 - Efficiency Below Threshold Again, there seems to be a few trains of thought as to what this actually applies to but generally most agree it's either DPF (differential pressure sensor) or EGR cooler. I do not suspect the EGR cooler as being at fault as the Exhaust Gas - Recirculat. (spec.) & Exhaust Gas - Recirculat. (actual) are fairly close. I have added a table below with a snapshot of the log I took yesterday. Based on further up I would suspect this code is related to the DPF pressure sensor in my case, would anyone else agree? My main theory at the moment is that the DPF is failing to regen, and at lower exhaust pressures, it's causing the hesitation. As soon I am over 2krpm, there is enough positive pressure to overcome the dpf restriction and it drives fine? My secondary theory is that the EGR tends to shut over 2k rpm, and it is the EGR flow that is causing the issue (either too much or too little recirculated gas). Though since cleaning the EGR the issue still persists and I can see the EGR duty fluctuating over 2krpm in the logs. Does anyone have any further insights or recommendations?

Hi Team Please could suggest what is the best, simplest, cheapest way to enable Sav nav in Audi A3 2014. I don't want to buy another set nav for GPS. I am fine if it's get connected to my Android phone for GPS. Whenever I connect my phone for music it gets connected but I don't hear ever Google maps navigation from the speaker, It goes blank. Not sure what is the issue. Any suggestions.

Hi all, Looking for some advice with my Audi A3 - Around 2 years ago I had issues around once a month where the car would be spluttering in gear (often 4th) causing me to engage the clutch or drop a gear, as it felt like the engine was labouring despite the revs being around 2k. Another side effect of this was the engine knocking or clunking abruptly when turning the engine off. I had a new throttle body fitted and all had been well and the clunking had stopped until recently. Current status is the car on startup is starting but the revs drop really low and the car splutters and physically jolts. Equally when shutting the engine off I’m now back to having an audible and abrupt clunk. The issues on startup and shut off are not happening every time which is causing confusion I’d say it happens 7/10 startups. Any thoughts on what could be causing this? I have no lights on the dash and the car seems to drive ok once the revs have settled after a couple of minutes. The engine is a 2.0tdi with 111k on the clock appreciate any feedback, BP

But just wondering if anybody here would have any idea what this clicking noise is when the engine is revved? Or is it normal? attached is a video of the engine running Thank you Helena Audi A3 1.6 TDI SE Sportback Diesel Manual

Hi all This is my very first post so hi to you all. Im sure this question will have cropped up before but I'd like to ask you all. The passenger rear window and central lock is not working. as for the window this does not function from any point wether it be from the door or the drivers switch. The lock is pretty much the same it's unlocked and won't lock at all not even with the key. Now due to them both not working in the same door I'd assume the issue is related but I just don't know enough to be sure. im hoping someone can advise me as it's probably happened before. thanks in advance mark

Hi all. I'm new here, in hope of helping me understand some of the frustrating things my car does. It's by far the nicest car I've owned, it's fast, comfortable and well looked after BUT man its quirks send me round the bend sometimes. Really grateful for any advice anyone can give.. Most pressing issue is the failing central locking, I now have two doors which will not unlock with the key fob, they will - once opened manually from inside - however - lock with the fob, so it seems the mechanisms do work, at least in one direction. I've done a bit of digging around in the forum and it seems this is a common Audi of a certain age issue?.. there's mention of cleaning the motor armitures in those particular doors and I'm going to give that a go, is this something anyone here's done and did it work? did you need any specific tools? did you regret it and end up taking it to a garage and it costing a fortune? Is there anyting I should check before taking things apart? Many thanks Pat

Hello Everyone, I Have a Audi A3 S-Line Black Edition 1.8 TFSI (Petrol), Recently the oil has been burning more than normal, My car's oil light is coming on every 300 miles instead of the usual estimated 1000-1200 miles from Audi.I had the car put on a oil consumption test and it failed at 304 miles before the light came on. Audi are stating to me the only thing they can do is replace the pistons and cams and hope this solves it. unfortunately as you can imagine the cost on this is more than buying a new engine due to the labour costs (estimated 20 hours). Has anyone had an experience with this issue and could be a simple fix (seen something about a choke valve sometimes sticking causing this problem? please help if anyone has any advice!

Hello everyone. Would anyone be able to tell me the colour code for this please? The sticker in the boot had completely had it so i have no way of finding out. I'd be so greatful if someone can help. Thank you

Hi everyone, I've just bought my first car and I stupidly forgot to check that the radio worked correctly. ☹️ The radio will turn on but none of the buttons work, e.g. to change the station, or to access AUX. Does anyone know what the issue might be and how to fix it? Should I replace the whole radio? Thanks, Elena

Hi, I went to look at a A3 2011 1.6 TDI S line 3dr today with a view to buying. Lovely car, great condition. My only concern was a ticking noise coming from the engine bay when idling. Just wondering if anyone has any ideas what this noise could be? Video included in the link below. It's not the easiest to hear but it's the ticking noise every 1 to 2 seconds that you can hear in the background. The car has had a recent cambelt and water pump change. It has done 77,000 miles. https://photos.app.goo.gl/5x5AWop6bGdFEe327 Thank you in advance.

Hey! I have Audi A3 8P 3.2 V6 and my transfer box is broken and now im trying to find new one... does it need to be exact same model than mine or is it just okey when part number (0AV 409 053P) is right? does it matter if the box is from 4 cylinder car? 🙂

I jet wash the car to find out later on my front right dip head light, right fog light, right rear indicator, front right indicator and the left rear side light isn't working. Any ideas what the story is here?

Hi All, I am very excited to have ordered my new A3 Sportback a couple of weeks ago. The 'YourAudi' tracker is currently saying that my build is expected to begin on 28th November, which I assume means delivery towards the end of December, which seems an awfully long time away!! (Patience is not my greatest virtue...) I was just wondering if anyone has ordered an A3 or any other model in recent times, and how accurate they found these dates to be? From a bit of googling it seems these dates can swing about fairly wildly? The dealer predicted delivery by the end of November when ordering.. Any info much appreciated! Many thanks, Rob

Hey everyone! I’m excited to join the Audi squad and am collecting my used A3 S Line Black Edition 1.4 TFSI a week on Monday. As with anyone buying a car, I’m currently obsessed with any little upgrades I can make but am someone who definitely likes the factory look as opposed to aftermarket. Therefore two quick questions! Has anyone painted their brake calipers or got caliper covers? I’m getting the car in Daytona Grey and think a little bit of colour will look great but want it to look as factory as possible. Also I’m really not handy even if it is the case of just removing a wheel for covers. Finally my car is a 66 plate and is the facelift 8V but am not sure whether it comes with CarPlay or not? Any ideas? Cheers in advance! Terence

Hi everyone. Was hoping for some advice. Looks like my abs pump/ module has a fault as traction light comes on and won't clear. Was just wondering if for this model can you take the electric module off without disturbing the actual pump so I don't have to bleed it again. Thanks any advise will be great

Hi guys I need some help out here, I’ve got an s3 8l rear diff whining and found another rear diff of an a3 8l. Are the compatible to swap over or are they different in some way. thanks for everyone help

Afternoon all, I am currently looking to purchase some wheel spacers for my Audi A3 Sportback 2020, Blackedition, but I am unsure on the track width size of spacer to purchase with this being the first time buying these. Wondering if anyone has any advice on brands, potential track width (to look aggressive and in line with the body work) or any extra info that might help or need to be aware of? Pictures of those fitted are welcome. Thanks.

Hi I’m new to the site and was wondering if anyone has had an oil pressure warning come up in the middle screen of the car is there a common fix like replace a sensor or something thanks

Hey guys, I were driving home from work earlier on when I drove over a nasty hidden pot hole. It went with quite the bang. Just turned my headlights on now and the passengers side dipped beam seems to have dropped leaving a weird line of light in the road as i drive. any advice on how to fix? :) thanks. (I also tried manually adjusting the light with the screwdriver and that did nothing but move it up and down)
