Thank you Sir! Just subscribed to your channel, after I watched about 10 different videos from several different channels that gave no real advice, just a lot of bullshit. I have an Audi Q5. Two different repair shops wouldn’t even attempt to look at my car. Finally Firestone guy said to bring the car to them, I did and they kept me waiting almost 5 damn hours. Now I understand shit takes time and no one likes to be around a demanding impatient asshole that’s chosen to wait on a car diagnosis and or repair. After 3 hours they finally moved my car close to a bay. Hood and door open, technician plugged in the scanner. I waited another hour, noticed no one around my car and the mechanic had started working on another car. Ok. I asked the service advisor if he had any information or update, he replied yeah, they are still in the diagnostic stages. Ok. After FOUR & 1/2 Hour’s of WAITING, I asked again for an update, still no one around my car, hood open, door open, scanner plugged in, he once again said, yeah man were still in the diagnostic stages of finding out what’s wrong. I walked out to my car, politely asked a few mechanics that were eating lunch about my car, they said the guy working on it left a couple hours ago, not sure if he’s coming back? Well Fuck that! I told the service advisor to unplug their scanner and give me my car back. I was charged $139 for a diagnostic fee. No codes given to me nor any diagnostic or repair information whatsoever. I paid, drove next door to an Auto Parts store, guy came out, plugged in a small scanner, said Code 303, and explained what that was. No charge. ***Right now I’m still at the Auto Parts store and after watching your video, I’ll replace all spark plugs and if need be replace the coil. Thanks for allowing me to Vent, I sincerely appreciate your expert knowledge and the fact that you are sharing said knowledge.***. Thanks again, Mike
@@Seriesxnation I still do not know what’s wrong w my car. Parked for all this time. Our local AUDI dealership informed me that there is a 2 MONTH waiting list, then they informed me that they would not work on my car because it’s over 10 years old. Something about only using OEM PARTS and they may not be available for my older car. So…, I found another repair shop and will take my car there and LEAVE. They also have a long waiting list but will work on this older car. Very frustrating. I have hung a couple of parts on my car to no avail. I believe the downstream O2 sensor, passenger side is screwed up causing the issues. I’m not gonna hang any more parts. I need a professional to diagnose and repair. Mine is the 3.2 and when it’s running good, it’s a great driving car and I still want the car, but after repair I’m seriously considering selling it and buying a newer AUDI. Mine is the Generation 1, Q5, 3.2 Turbo. It’s a Love Hate relationship. I do have 250,000 miles on the car and honestly believed I would be able to maintain this car. More involved than I ever thought. Oh, very possibly a Fuel injector gone bad #3 cylinder, but again maybe the O2 sensor is causing this problem. Stopped driving, don’t wanna screw up something else. Did you get your car repaired?
@@MW1_2_3 no I'm having an issue with 12 q5 2.0t with 125k miles. I've owned it for 5 years + great car replaced maintenance things on it a lot and 4 months ago the HPFP went out I fixed it and its been good until p0303 cal 3 misfire started I moved coil packs but didn't work I'm just waiting to get it diagnosed from professional
@@Seriesxnation P0303, if it’s not the coil or spark plug. It could be a number of things. Agree on professional diagnosis. Save money not hanging parts. I did replace the coil and spark plug w OEM. Didn’t help. I’m still waiting to get mine in the shop. Good luck, we may need a little luck.
@@MW1_2_3 ya my guess recently based on all my research even from other forum owners is after the coil, spark plug it’s most likely the fuel injector gone bad. After that might as well prey lol 😂 but for 250k miles on ur car that’s a lot and it’s not the 02 sensor because it tells u it’s an 02 sensor I’ve replaced that 3 years ago
I read that misfires codes are detected by the crankshaft position sensor & how much the engine slows down between cylinders firing. With misfiring on my B6 ALT, but no codes thrown up, I replaced coils & plugs ( quite worn ) the new coils fixed the problem. Did cam cover gasket too. Meanwhile on B6 ASN , cam codes, Missfire, camshaft timing was out, fixing that ( easy with tool ) fixed cam sensor codes. VC solenoids needed cleaning too. Now just misfiring 4-6, needs new coils., Replaced plugs. Cleaned injectors ,& MAF & replaced CVS valve. Coil on plug tester would be usefull for quick coil diagnosis. ( Looks like pistol with tiny fly away on it, cheapish. Or $$$ ollisiscope sort to check voltage ramp etc. )
Man u help me out just then i got them ebay NGK spark plugs 17000 miles now a misfire the fuck thanks that might be the problem will try new plugs from a good Source 👍
I have an OBDeleven tool that scan my codes and I must say I have a unique problem I don’t think many mechanics seen this nor can I find any research on it but I have codes p000A witch has prolonged a little prior to my car break down, p0300, p0303, p0304, witch those two cylinder always take turn between active and in active, and lastly a tricky p0087 codes. With this information I must include that my car shakes horribly bad and smokes blue. I took it to a mechanic and honestly they just tried to make money off me by saying the problem was way worse. They concluded piston rings witch isn’t true I think Bc I’ve had no symptoms of them going bad prior to my break down. I was thinking a leaking cylinder head cover but I’m not for sure. It’s hard to actually diagnose. This take some high level knowledge for sure I hope you can reach out NaptownTuner
Hi Naptown, like your videos! I have a 2012 VW CC 2.0 tsi, recently I am experiencing a hard time because when deeping the accelerator, cylinder 2 misfire increased quickly and the engine is shaking. sparks and coils are OK, and I did the cylinder compression test and all 4 cylinders are around 130 psi which is not good but not that bad. I am thinking if there is anything wrong with the fuel injector in cylinder 2.... any suggestions will be appreciated!
I have a 2012 a4 b8 2.0 tfsi. Been chasing this misfire p0300. I did a carbon cleaning, new injectors, new spark plugs and coils, new coil wiring harness and connector plugs, new timing chain,tensioner and guides. Still misfires I need help
I'm hoping that the G.O.A.T can help me pls. I have a 2010 a5 2.0 tfsi quatrro. Once up to temp occasionally the revs drop for a second when driving and the stop start kicks in at random times. I have 2 engine codes, p008800 and p032200. I'm begging mate for your expert opinion, pls 🙏 from a subscriber in the uk 🇬🇧
So I've replaced coils and plugs with name brand audi coil packs and ngk iridium and still have misfire on cylinder 1 and throw p0301 code what else could it be? Car makes weird noises on decel as well any info would help.
Having the same problem with my Car I have changed the Coils and spark Plugs giving me a lot of oil out of the Oil separator that I have also already replaced and a lot of white smoke and misfire
I have a 2013 Audi A4 , I changed my spark plugs, coils, got a oil change and changed the high pressure fuel pump and its still getting codes p0089, p0300,p0301,p0303. can you please help me. the car have 163,000 miles
Hey naptown tuner can I get some help or advice I have a 2012 audi a4 quattro and on the freeway the check engine light flashed for a couple of seconds and went away then the engine began to shake and loss of power, so I towed it home scanned it with obdeleven and only had a p0302 and active non stop reading, so I did the obvious replaced all coil packs, spark plug, and went and replaced all fuel injectors, got the cylinder head rebuilt, replaced all timing chains both upper and lower, and once all back together erased all codes purged gas all new fluids and still got same code p0302 what could it be ?? Please help
@Seriesxnation yes I did that 0 compression in cylinder 2 though it was the valves and replaced it and had still 0 compression so I prayed it was just the rings but nope a quarter of the bottom of the piston blew off luckily to oil pan and didn't damage hone on block and replaced just all 4 piston
I have a p0302 and a p0011 and p000a I've had my timing chain and tensioner and my intake camshaft replaced be greatly appreciated if you have any ideas of what I should look at first. My check engine light isnt on but my Epc light is on. Please any help is appreciated. I cant find these codes on your videos. Engine was turned over by hand 6 times after replacing chain been driving for months afterwards.
Anyone else here give NaptownTuner a thumbs up and subscribed because you feared that if you didn't, NaptownTuner would show up at your house with those XL meathooks, shaking and intimidating your very soul through those shades? Not me... personally... but like you guys... did you do that? Just asking for a friend.
@@deejay4837 I'm fairly certain it's a carbon buildup on the intake valves now that I've looked into it. It got a bit better after driving cross country.
Hey Naptown Tuner, I have a 2008 Audi A6, 3.2 Quattro, I have replaced both my coils and plugs and I continue to receive misfire codes for my second coil. Replaced #2 coil's plugs twice, Bosch and Audi plugs. I get an ESP light, ABS light, and check engine light after getting to 3,000-3,500 RPMs then car shakes. Do you have any insight? My mechanic is stumped and I have been pouring money into this POS, any info would be appreciated.
I have been trying to solve a intermittent miss fire issue where the car dives great and then will randomly misfire where the rpms drop in & out for a few seconds then is fine again. This may happen multiple times in succession and then not happen again for a day or 2. I have been surfing forums and youtube and have tried all of the solutions that had similar symptoms with no success. Things I have done so far: spark plugs, coils, fuel lines, fuel filter, carbon clean, cleaned injectors, clean MAF and no solution. Any advice on what to try next would be appreciated.
I have a 2010 audi a5 2.0t in the shop, 150k miles. Came in running crappy and intake flap faults. Customer authorized intake replacement and carbon clean, prolly worst valves Ive ever seen. Afterwards we drove it to clear out everything and when you really get on it (close to redline) it starts to misfire cylinder 2 (looks like a lean miss based off of HT lead and pico waveforms). Replaced coils plugs injectors with new OEM bosch/NGK and issue persists. All in-cylinder analysis waveforms look fine i cannot figure it out... it only misfires if you floor it thru the whole rpm range and right around 5.5k rpm it starts to flash misfire cyl 2. I also feel like i smell burning oil when it happens.. anyone experience this?
Omg I love you. Every other car repair video is so boring and unnecessarily long. Thank you for being fun and concise!
could have been 1/2 as long
Cause of my misfire at start was fuel injectors #2 & #3. Just putting it out there, when I removed the injectors #1 & #4 where a lot cleaner.
2,3 had major carbon.
Your video is helpful! Misfires are major concern on TFSI
1) spark plugs
2) coil packs
3) vacuum leaks
4) crank case vent
5) fuel injectors
Off coarse given you have good compression test in all 4.

What happens when you can hear misfires (hiccups) at idle, but there are no codes?
You need a scan tool to see if they're actual misfires. Are you describing something that happens at cold start or at operating temp?
