I hate when a mechanic says: it needs a new engine. You dont need a new engine. Im not a mechanic and i did the job myself. The problem that engine has is a broken valve. I will explain what happened to the engine to.... When that spark plug broke it was glowing so hot so it melted a hole in the valve. So just replace the valve and its good to go.
The valve cover gasket?
@@camhitemup4121 not valve Cover. Every cylinder has 4 valves and 1of them has a problem. They are dirt cheap. Its not hard to fix. Just take your time and follow a youtube video to put it all bak in correct order. I can open up the engine and assembly it in 2 days. Its much easier then people think.
Can you help me like they keep saying that and that’s not the issue
@@jimmybjorklund1491 I have a 13 Audi a6 3.0 supercharged and I’m having misfires all on bank, any ideas ?
@@jimmybjorklund1491 Do you mind linking the video? I could only find exhaust valve replacement and no intake valve. About to have to have to do this for my A4 with same problem in the video.
Edit: Nevermind
Boy! These VWs (Audis & Porsches too) are a nightmare.
question so my 2009 audi a4 2.0t also has a rough idle and all the coil packs had oil all over them but when i pulled the spark plugs the part that sparks looked good no oil all looked old but normal what’s your opinion you think it’s just the valve cover gasket as well?
So what was the issue
Whats the issue?
What do I do I got a 2017 and it keeps making loud sounds and giving false signs??
This is what my car is doing. I have a 17’
Dealership charging 2,700.
Great video buddy learned a lot. Helped me fix my issue
I have a question since you know about Audi 2.0. I’m working on one right now. And I cleaned the carbon buildup. I also put new injectors. All new coils all new plugs. My cylinders look clean. After 40 mph I’m having random misfires still. Could you maybe give me a little advice what you think I should do next? The car runs great until after 40 mph. It starts misfiring check engine blinks EPC light comes on.
Any luck yet I’m having same issue
@@bluesscreensdreams8725 Ya what it turned out to be, is the timing spool was turned all the way out. The timing chain was stretched. I had to take the front clip off, but after I did that very easy access to the timing chain, and tensioner & guides. I have never worked on an Audi before. So I use this whole Audi as a learning experience. I do not like the 2.0 engine I know that now. But after all of that it runs like new! I saved a ton of money, doing the timing chain and injectors myself. I had carbon buildup and a bad injector I figured. But I wonder if I would’ve just did the timing chain in the first place if it would’ve corrected everything. Who knows everything is brand new now. There’s a little hole on the bottom of the tiny chain cover. You can pop it off. Get you a mirror and you’ll see a little spool and you can count the turns of the spool. If you see six or seven, turns. Your timing chain is stretched. What is happening when you hit third or fourth gear. Your car has jumped timing, so it starts random misfiring. Hopefully this helps y’all!
can somebody tall how fix nissan quest 2012
Actually u get comp like that when no oil in cylinders… its been flooded with petrol.. thats why
What was the decision by the owner with bad engine
Probably scrap the car lol
hi, how do you know you're in the compression stroke. or intake or power or exhaust stroke? thanks.
good question, maybe he is indexing based on Cyl 1 TDC
Well done John.
I have got a 2009 a4 avant 2.0tdi and its revving by itself when idle. No engine lights come up and no faults codes as mechanic did a test. The car itself drives smooth with no problem in gear change. Just when im idle.
Throttle position sensor?
I changed the throttlebody on mine. And the sensor was on the side. And it corrected all high idol in park.
Pcv@@ghostofsoufeasthoustone
Thanks for the quick brm info cuz I have one 🤣
Could just be stuck piston rings. This happens on like all Audis 2010-2016
Happened to me. Engine was trash. Lucky me. The car had a month left on factory warranty
This guy is a bawws ✌️
This engine under 2012 use a lot of oil. When we know this, its better to replace the engine. New pistons doesn't have this problem.
I have a 2011 a4 with 125k miles and it dosnt burn oil… why is that
@@sweetandsour6521 problems only on petrol cars tfsi, not diesel.
@@MrZona93 haha yup ik mine is gasoline too I changed my oil evry 3k miles and it’s always still on the max line in my dip stick
