[@waynesworldlydrawerings1]

Thanks for this, you just saved me a big mechanic bill! Rock on

[@chillymooose]

That is great to hear. Thanks for watching and good luck

[@staphaniereid3745]

Thanks Chilly Moose! Learned a lot from this video! 👍

[@ayotokunojoao9725]

what if you have two ignition coils that are bad?

[@BlockIce84]

Thank you, good video, my ignition coil #4 I think is bad. I will try to change it tomorrow.

[@ayotokunojoao9725]

thank you. I will try and update you. My car is vibrating and hard to accelerate so I didnt know if it was safe to drive to a mechanic. Let me know what you think? Do you also advice to change all the coils and spark plugs?

[@chillymooose]

@@ayotokunojoao9725 try one at a time. However, if you can afford it. I would do all of them at the same time Thanks for watching

[@dwightblack9577]

Great video bro it really help me

[@chillymooose]

Thanks 🙏 I appreciate it

[@wichoernandez1]

Read codes always p3001-2-3-4 last number its the cylinder but be careful because can be vented valve or timing chain jump .. codes are very helpful

[@zilla3701]

What do I do to get rid of the epc light

[@chillymooose]

You can either go to an auto parts store like auto zone or pep boys and ask them to clear your codes. Or you can purchase a cheap code reader and reset it yourself.

[@zb5099]

I have the same car and I just started running I. Some problems with it when I start the car and drive the dash closed turn off completely and turns back on

[@chillymooose]

Sounds like you are having some sort of electrical issues. Could also be the computer acting up. When the dash turns off, does the car lose power or does the engine keep running normally?

[@zb5099]

@@chillymooose the engine runs normally it just turns off and on and I loose power steering when dash turns off

[@chillymooose]

If you can get a scanner hooked up to the computer, it might tell you a code. There could be codes in the computer with out having the check engine light on. But only way to know is to scan for any codes in your computer. Also, just as a suggestion, it could be your alternator acting up. You can check this by disconnecting the battery while the car is idling. If the car wants to shut off or actually shuts off, then the alternator is bad. Hope this helps. Please keep me posted

[@kimterry9525]

So how did you get the lights to go out? Did you disconnect the battery for a period of time?

[@chillymooose]

Yes you can disconnect the battery over night or reset the computer with the OBD 2. If you don’t have one you can go to an auto parts store and have them reset it for you

[@everettknight8591]

Very Helpful Thank U !!

[@chillymooose]

No problem. My pleasure

[@rongdizhu8807]

Thats the helpful video that I ve been looking for !!!!! thanks !!!

[@ExtractFilms]

This worked for me! Thanks!!

[@chillymooose]

Great! glad it helped out. thanks for watching

[@calmz2343]

So how do you get rid of that check engine sign?

[@chillymooose]

You would need a code reader to erase the code. Or depending on where you live, you can go to an auto parts store and they can erase the code for you. If you need the name brand of a good code reader, let me know. I have a really good one.

[@AliVapeReviews]

I’ve got a Cylinder number two miss fire i was with a friend and I just said for the he’ll of it read to see if there’s any coils as I had a code for Air system insignificant flow bank one which I don’t know how to fix that and said I had a cylinder number two miss fire I’m hoping it’s just the coils and spark plugs because since I bought the car I haven’t got new ones and I’ve had my 2014 vw cc 2.0T sport in red for only 8 months which is Cylinder two the second from the oil cap side ?

[@chillymooose]

Yes that is correct, cylinder two is second one from oil cap.

[@AliVapeReviews]

chilly moose well I guess you can call it a test so I had the car running pulled out every coil one by one and if I ran different of changed the idle it was a good coil so I did that to all and all are fine spark plugs are all fine just a little black so not from the coils but I don’t have a check engine light for it anymore and I cleared the codes and only one came back was a p0491 which I don’t know where to start with that code as I’m new to vw this is my first vw car and German car damm is it a pain in the ass I can sure say that but love it drives nice mine only has 72k mikes 2014 vw cc in red I’ve got the sport sadly when I bought it couldn’t find a r line or the other one in my state

[@chillymooose]

Yes... they are good cars just high maintenance. Good luck with it.

[@marwanadam6060]

Hi, I have Passat cc 2013 TDI, automatic gearbox, the issue is- when the engine is running I hear a sound in the engine kind a little vibration or probably engine’s cover shaking, but once I put my foot on the accelerator the sound goes away immediately, also today when I parked the car on a (P) gear the engine shut down by itself, and that all happened after I floored the gas pedal on the high way. Hope you can give some advices about why this is happening. Thank you

[@chillymooose]

Marwan Adam, there can be many things going on... but off the top of my head, it looks like you may have blown a head gasket. A couple of questions I have is... is the check engine light on? If so, what’s the code? Is there a loss of power during acceleration? Let me know. And thanks for the question

[@marwanadam6060]

@@chillymooose thanks for your reply, there’s no check engine light on neither a loose of power during acceleration, the little engine vibration goes also away when I shift the gear from P to R,N,D, so that happens only when the car is stopped, kind a rough idling of engine, jerking and once I push the gas paddle the sound/vibration goes away. I doubt is the coils and sparks plugs causing this idling? Or should the check engine light shows in the dashboard in that case?

[@chillymooose]

Oh ok, sounds to me like you have a very slight vacuum leak. This is common in the VW’s. I would check PCV valve. You can also search “VW rough idle” here on KZbin.

[@briancardenas7352]

Did check engine get removed over time or how can u remove it?

[@chillymooose]

It will go away over time Or you can erase the code if you have a code reader. Some cars you can disconnect the battery overnight and it will erase the code from the dashboard but never tried it with the VW because i have a code reader.

[@keithyiu5710]

hi. May I know if we need to reprogram after replacing the coils?

[@chillymooose]

Hello No you will not need to reprogram after replacing the coils. Thanks

[@joshuatoe2323]

Hey Chilly happens to come across this video as I was doing some research into buying a 09 vw cc. As it seems you have experience working with this make/model. Would you suggested it at all or should I steer clear. Ironically enough my second option happens to be an optima which you have in your driveway lol…thanks for any insights!

[@chillymooose]

The VW is a nice fun car that gives great gas mileage. Unfortunately the turbo is very high maintenance. The engine compression is so high that engine oil would make its way into the turbo. If you don’t mind all the maintenance on the turbo its a great car. I just didn’t have time for all of that. Thanks for the comment and hope this helps.

[@joshuatoe2323]

@@chillymooose thanks for your response…that lines up with what I’ve found especially with oil consumption, timing chain issues, and carbon build up. So would you say that the optima is a better option then, still offering some fun but not with the high maintenance costs and time?

[@chillymooose]

@@joshuatoe2323 absolutely, slightly less gas mileage but the low maintenance definitely makes up for it. I have about 120k miles on the optima and it still runs as if it just rolled off the lot.

On my European cars all German with the exception of 3 Saab's and 2 Volvo's, I NEVER use aftermarket parts as I'd rather pay more for the accurate OEM parts to ensure no problems with the car. Was that coil an OEM Volkswagon coil that you bought on Amazon or was it Chinese made aftermarket? Loved the train horn in the background!

[@chillymooose]

I agree… genuine parts are the way to go. However, it a cheap way to confirm that it’s the proper fix for the do-it your selfer.

[@bhigdaddymark]

@@chillymooose Thanks for your response. I've got another question for you, what's the best/least expensive way to address the carbon buildup on those 2.0 TSI engines as the dealer (in my area) wants $2,700 to clean out the carbon buildup. I'm getting a 2010 CC in January (haven't had a German car since 2010) and I'm not looking forward to going back to buying 93 Octane gas and the potential maintenance headaches with said German cars, it'll be my 5th VW and 7th VW product (I've had two Audi's) so I'm a bit concerned as at my age, all that I want is trouble-free car ownership (I should be getting a Toyota or Honda instead lol). Thanks for the informative video.

[@chillymooose]

@mark i am not to familiar with any procedures where you can clean the internals of the valve assembly inside the head. I have seen some advertised head flush procedures at the local jiffy lube and places like that but i have never opened up a head assembly and verified the results of said head flush. Only way i know of is the old fashion way, of taking the head / valve assembly apart and hand cleaning them. Hope this helps. And thanks for the support on the channel. Good luck with the CC. They are great cars.

[@bhigdaddymark]

@@chillymooose Thanks again and you said EXACTLY what the service advisor at the dealership said nearly word for word. Thanks, hope you and your family had a great Thanksgiving.

[@CaddyBrokeDown]

I’ve replaced all my coils 3 times in 1 year

[@chillymooose]

What brand are you using? Just curious

[@maxo.1062]

Good day chilly, so my car misfires, exactly same as this in the video. Sometimes it drives good & sometimes, gives the warning sound the moment it starts misfiring. So i have couple of questions, how do i determine if it is the coil or plug that is causing it ? Secondly, how long do i drive it for in it's current condition before it becomes really bad news for me?

[@chillymooose]

Max O. Perform the coil check procedure as i have shown in the video. With the car on, unplug each coil one by one. If there is no change in the rpm dropping, then that is your bad coil. I would not drive it like this too long. Because you can risk damaging the cylinder. It might be a good idea to change all the spark plugs. These are not too expensive and will help in diagnosing if the problem is actually the coil or the spark plug. Let me know if this helps. Good luck

[@maxo.1062]

So, i unplugged i did check the coils exactly as shown in your video & it turned out each coil caused change in the rpm dropping. For that reason, i came to a conclusion that it isnt the coils so i entirely unplugged everything & checked one of the spark plugs & screwed it back in, blew out dirts in each of the coil holes then replugged them. For like 4 days straight ever since, i havent seen recurrence of the engine so far & no signs of misfiring but then i dont wanna be entirely comfortable as i still look to clean the entire spark plugs & if i may ask, what cleaning agent for plugs do you thing i should get for that purpose? Thanks a million

[@chillymooose]

Max O. I use regular carburetor cleaner for the spark plugs.

[@maxo.1062]

@@chillymooose Thanks, will keep u updated

[@maxo.1062]

Hello Mr Chilly, so my car started misfiring really bad after the last update as it was only working on one cylinder & that scared me a lot so i decided to changed the entire spark plugs with irrinium ix & still left the old coils as according to your demonstrations, they are still working. So now the car engine sounds perfect but the EPC & Engine lights are still on the dash board, how can i clear them with OBD device?

[@golfmaniac007]

VW is finicky with their parts. $13 part from Amazon is gonna have issues later on in short time

[@chillymooose]

@@golfmaniac007 agreed thanks for the feedback, 7 years later and still working well. But it’s a gamble as to the parts you get
