Finally someone working on the same engine as mine 👍 good video you have helped me out mine are starting to go bad idle on cold start is all over the place
Warm up the engine first then soak the plugs in WD40 for 10 mins then remove them, tighten to correct torque (they are over tightened on this video) replace all four at same time even if only one is faulty.
Thanks glad you enjoyed the video. From what I know it's a bit harder to know exactly which one is at fault unless your engine is misfiring then it would be easier to identify which one is causing you problems. Most of the time all of them go bad roughly around the same time, so if you have any symptoms of your glow plugs being bad you should replace all of them at the same time not just 1 of them. You could also take them out of the car and physically check them to see what one is in very bad condition maybe 1 of them would look a lot worse than the others then you'd know to keep an eye on that one. It was a while back but I think I only paid £15 for all 4 of my glow plugs, I bought them on Ebay brand new, from what I saw they were not very expensive.
I would say if you haven't changed them in a very, very long time or if you drive alot of miles each year and haven't changed them in a long time then it would be good to do so. If you notice any of these symptoms its also I good idea to change them. Hard starting. A hard starting engine is the most common indicator of damaged glow plugs. ... Engine misfiring. ... Rough idling. ... Decreased fuel efficiency. ... White smoke. ... Black smoke. At the end of the day if you do change them you at least have that piece of mind that everything should be ok for a while. Hope this helped 👍
If they are still going strong then I guess theres no need to change them but if you want that peace of mind that they will last another 90+k miles then I'd go for it. No harm in changing them early 😁👍
@@RCS_716 ah hard choice tbf, they can last up to 150k miles from what I've seen, or more... do not want to spend money unnecessarily lol. Would enjoy a full coolant change guide for the 6R if you know how to🙂
Just a question.. i have a polo tdi 1.2. Few months ago it used to rough idle. I poured fuel system cleaner and the rough idle/misfire was fixed.. But then After few weeks it came back. I us3d the cleaner again it got fixed again but now it just came back again. Do you think its the glow plug, the fuel filter or fuel injector?
I'm not too sure which it could be as it could be any of them, mine has a rough idle aswell but when I turn the A/C on it stops then when i turn it off it starts the rough idle again. It's weird lol ( I'll have to look more into it ) As I'm not too sure the best advice i can give would be to go the trial and error route and try all the options until it works, or you could bring it to a mechanic and see if they can diagnose the problem. The only downside is that both methods might be a bit pricey though.
@@RCS_716 i just changed the fuel filter and i hope that was the issue. In your case don't u think its the egr valve?. Did some research on it and i think mine needs cleaning cos i hear a noise occasionally when idling but it goes when i put on the AC. Problem is, its very hard to clean/replace
I've currently got my egr blanked so mine isn't even really doing anything at the moment but it still does the rough idle sometimes, it still did it before it was blanked aswell so that makes me think that it's bot the egr but I could be wrong
@@RCS_716 strange. Idlijg problem are very common on polos Just a question. Since i bought my car few months back i never noticed the engine light never showed up when putting the ignition on. Just yesterday on my mot the mechanic told me. Engine seems to be running fine tho since i cleaned injectors and changed filters. Im assuming the sellers hidden it before selling it. Do ypu have any clue on how to bring it back. Mrchanic told me its an electrician job and would charge me £140
I'm not too familiar with golf's as I dont have one but I tried to do a little research into it and from what I found I believe on some golfs there is 1 or 2 cylinders that the glow plug is different because they have pressure sensors on them ( this makes them cost considerably more than your normal glow plug ) I'll link you to a forum that I found with a video that might be able to help you out 👍

I got Passat 2.0 tdi diesel one glow plug needs to change but I’m gonna change 4 of them but it’s shit on the fuel What do u think cause of the glow plug??
I've looked online and found a few reasons why your glow plugs could have failed, I'll share them below. You have the wrong glow plugs for your engine Your engine excessively overheats Your engine operates at voltages that are too high Your power supply is too long (often due to a stuck relay) Your pistons are damaged Your valves are broken You have a seized piston ring The injectors have dripped onto the glow plugs and eroded them. Another common cause of damaged glow plugs is high-amperage battery chargers, which are used to improve engine starting. These chargers can provide a voltage high enough to explode the glow plug tips. Also I'll link this website that I was also on that provides pictures of different glow plugs and there conditions and the causes for the different glow plugs. www.roughtrax4x4.com/blog/common-glow-plug-failure-causes/ Not sure if this is what you were asking for but I hope it helps 👍
I haven't got a straight forward answer for you sorry. When I changed my glow plugs I thought they were the problem because the glow plug light was on, on my dash. ( I replaced them and the light was still on ) I then used a scanning tool to scan for the problem and turned out the reason why the glow plug light was on was because of my dpf filter. I then did some more research and it turns out that there are many problems that can cause your glow plug light to illuminate on your dash ( and the glow plugs wont even be what's wrong ) But if your glow plugs are the problem ( I can only make a guess here, so don't take my word for it ) then the light will probably go away once you change them, it it stays on then it might disappear after 5 or 10 mins. If you do change the glow plugs and the light is still on your dash then you've got something else wrong with your car. If you've got a scanning tool or anything like that I would use that first just to see what code it gives you so that you know exactly what the problem is. Sorry that this probably isn't the answer you were looking for but I hope it at least helps a bit 👍
In my case yes I managed to get the problem fixed, it was due to my dpf filter getting blocked so eventually my car went into a limp mode. To fix the problem I had to take it to halfords and get them to clean the dpf filter for me, cost £85 which was much cheaper than everywhere else I looked. The car has been perfect ever since.
It isn't mandatory but it is highly recommended. Chances are if one is bad the rest are probably also bad or very close to being bad. ( its unlikely but ) Sometimes with things like these the car can act a bit weird if they are not all the same, so if your going to change them I'd recommend that you change them all at the same time.
Glow plugs are so cheap its hardly worth doing the work for one and putting the car back together without doing the others. The others will probably fail soon if one has one so its a false economy.
It's weird because I've had the glow plug light come on but the problem was my dpf, and I've had my check engine light come on by itself and the problem was my glow plug. If you have some sort of obd reader you can use it when your check engine light pops up to see what the problem is easily without having to guess or test a bunch of different things. 👍
Hi one of my glow plug few months ago seized so had it replace due to it not allowing the engine to regen itself.the same problem is happening again why does the glow plug seize?
To be completely honest I'm not too sure why that is happening. Maybe its not the right glow plugs for your car etc. Or maybe theres a problem with something else and that is causing your glow plugs to fail.
Hello brother, myself from India , mine is a diesel vw polo 1.2 tdi driven for 1lac18k kilometres From December 2011 to Aug 2021 till date , should I also change my car's glow plugs ? As there is no warning light till date ⚠️, but my car starts after very long cranking , especially when outside temperature 🌡️ is below 30degree celsius , when outside temperature is 34 to 35 it starts off easily , I was thinking maybe my battery (60ah) was bad as it was fitted 5 year ago since October 2016. So confused wat the symptoms are ? As the battery guy checked the acid gravity and voltage output both the values were fine , but he didn't have equipment and know how , to check (CCA) cold cranking amps , can't really make out when I turns the key to start and crank several times all the dash meter lights go off and then we have to push the car with someone's help and then crank to start Plz advise 🙏
It's hard to know exactly what the problem is as it could be a number of things like the glow plugs, battery or the fuel system etc. But if you've got the money to spend I'd reccomend trying the new glow plugs to see if that solves your issue. And it's a bit of peace of mind knowing that you wont have any problems with them in the near future. Sorry if this isn't the answer that you were looking for but I hope it helped 👍
@@RCS_716 thankyou brother , my car battery was weak as I got it checked today from an authorised battery workshop , it's voltage came down to 8volts instead of 10.5 or 11volts on cranking the starter, meaning thereby the CCA of the battery has reduced drastically resulting in poor starting or not starting
Good video but I was cringing when you tightened them up. Around 10-15nm for glow plugs. Some cars are only 8nm. Fortunately, VW used 10mm plugs instead of 8mm so a bit stronger.
Thanks glad you enjoyed. I don't think that I even owned a torque wrench back then 🤣 ( I also cringe at some of my older videos ) But I'm better now I promise 😅 ( still not great but im learning as i go ), now I try to research things properly and I get some helpful comments like yours which give me good information for the next time I tackle a similar job. I appreciate the advice 🙏 anything that helps I'll take on board, and it helps others that scroll the comments aswell :)
I would replace them just so that I won't have to worry about it in the future. But if you have an obd scanner etc you could use one of those to see what the problem is or what cylinder has the bad glow plug, that way you could keep an eye on it just incase that particular cylinder keeps acting up.
What about showing how to clean the glow plug seating holes(without pushing any rubbish into the cylinder head!!!!! )More importantly how to replace the new copper washers!!!!.(which you didnt mention).for future reference the glow plug to cylinder head torque settings are 18nm or 13 lbf ft..if your going to show the procedure then do it correctly and show the whole job .You can cause some serious damage..more so if you cross thread the plugs in the cylinder head or worse still if they snap when trying to remove them.Its not a straight forward job as you make it.
I needed to replace my glow plugs and thought I might aswell make a video on it. I'm by no means an expert on this stuff, just someone who likes to work on my car If the job isn't too hard. Perhaps replacing glow plugs is a more involved job than I made it look like but I did it how you saw in the video and my car is still good so I must have done something right lol. I appreciate the comment though, you've come through with some good knowledge and myself and others reading can learn from it so thank you 😁
@@RCS_716 it was not meant as nit picking .it was meant to help in a constructive manner.What can seem to be an easy job could and sometimes does end up being a very costly garage job, if not done correctly .It can be made a lot easier by spraying wd 40 round the glow plugs a couple of times over a day or two before changing .Not forgetting to clean round the plugs with a stiff brush to remove any dirt and crud (that always builds up over time)and wiped away,before attempting removal.Although the copper washer set is not essential they should be an automatic renewal as this only improves contact between plug and cylinder head and are not expensive to buy.Hope this helps
