Skoda Superb Broken Injector Bolt | Know Your Limitations

- Previously i showed you all the Skoda Superb Broken Injector Bolt and it was time to tackle the job.
I've tried to remove the bolt with a punch first in hope that the bolt would spin out, then i decided to drill it out which didn't worked and finally plan C.
I got in contact with Dave a Local engineer specialized in removing broken bolts and re-threading, it was the best decision to be honest Dave has a ton of experience and the tools for the job.
Unfortunately after turning the engine on it's noticeable that something isn't right internally , it was time to pull the Picoscope and check timing ...
Like i metion guys i am a bit green with the scope stuff and learning it slowly but surely, i believe i should have put it the first 0° ruler by the raise of the first square waveform and i've sent the waveform to @MechanicMindset and he confirmed it was actually 10° degress out , Cheers Darren 👍
I hope you guys enjoy this one ...

Was definitely a good call...
You can't always have all the tools when you only need them once in a blue moon...
👍👍👍
I couldn’t agree more mate Dave kindly offered giving me instructions in the future But I think i prefer to keep his number on the speed dial 😊🤣👍👍👍
Very detailed demo. Your bolt removal man very good to know his number. Thanks for taking the time to film. All the best Pete
Thanks mate ... Dave he was a life saver very knowledgeable man 👍👍👍 cheers
Always love to watch your all videos till end. Last week diesel specialist did same job on my seat altea xl 2.0tdi cfhc engine. He changed two injectors. One was seized no 2. Before starting work he told me buy two new stretch Bolts/injector clamp bolts. He told me that stretch bolt once we take out no use again even look ok.
What a brilliant video which has allowed me to understand why our Golf Mk6 1.6TDI has packed up. No sign of top half of clamping bolt and not yet sure if it unscrewed or sheared. Garage looking at problem tomorrow. Thank you.
Seen this fault before on a Audi A3 2.0Tdi It went back to the dealer as it had only just left there after having work carried out that required injector removal. Never found out the cause.
Definitely the right decision to get Dave round.
Thanks for the feedback mate ... indeed Dave was the right decision I’ve got his number in speed dial now 😊👍👍👍 cheers
Done a few of these, rocker off, cam bearing cover off, can leave timing belt on, with bearing frame off you can screw out by hand.
What causes the bolt to snap like that.
@@eddydar bolt is stretch to yield so one use only, either a new bolt not torqued to specs or a bolt reused.
I have just done the same job, very small chisel on top of broken bolt and unscrewed with flathead screwdriver👍🏽
good job and i will miss that car !!
Great job Igor & Dave! Shame about the end but that car has served him well and kept you busy too 👍😂😂😂
Lol she sure did 😊... a bit of a shame but it was time I think , and guess what the new car was around mine today already for some really minor repair 😋 👍👍👍 cheers Xx
@@CarsExposed oh goody! 😝🤣🤣🤣
Good explanation and excelent video.... cheers from Portugal and Stay safe!!!
Cheers Ricardo you too mate ... where abouts are you in Portugal 🇵🇹?
It’s alominum you don’t need drilling, the broken piece is sitting loose there , just use the snapped nut to unscrew the bolt from head or screw driver.
I wouldn't have liked to drill that broken bolt out, that was a good repair. It will be interesting to see the next part to this video.
I thought the same thing mate 😊... Dave the engineer that extracted the bolt was fantastic and quick very experienced chap ... we will see hopefully we have some more videos 👍👍👍🙌
Great job Igor 👍
Thanks mate 👍👍👍
Good work man
Wow what a failure. Definitely a job for a specialist to get that bolt out. The why it happened will be interesting to know. Great job mate
Indeed I never seen that happened before , yeah I didn’t want to risk it no gear and no ideia 😊 Dave was the right choice . We will see hopefully I’ll have the chance to dig a little bit deeper 👍👍👍🍻 cheers mate
So the broken injector bolt was the cause of misfiring?
This is great thanks. I literally have the EXACT same thing on my Skoda Octavia from Boxing day, nightmare. But did't have any engine issues beforehand so I hope that replacing the bolts will do it. I'm in Wiltshire and will be phoning the thread wizard tomorrow to extract the broken bolt, hope he's still going. Did you ever find out why yours sheared? I have the EGR blocked off, do you think that could cause excess back pressure!? Thanks again.
Wise...know when to pick up the phone. Best of luck if you move forward with it. Cheers Igor 👍
Always nice to have a helping hand 😊 Thanks mate 👍👍👍🙌
How this Bolt broke ? I need to change 4 injektors gasket but i dont have moment key .. is it possible do without it ? Where i need to be carefull
Great video Igor, do a Cranking amps or set scope to ac over battery terminals and look for odd man or men out!!!
Thanks Sandy , the vehicle has been replaced now it was time to retire it after covering nearly 500k ... we will see what my friend wants to do with it, I’ll do a relative compression test if I have the opportunity 👍👍👍 🍻 cheers
Good work mate
Thanks mate 👍👍👍
This happened to my car third time i dont know what to do now any suggestions?
Dpf blocked, can cause the back pressure
Thanks for the suggestion , I’m not really sure yet if the car will get fixed but we were planning to time the engine and if that happens I’ll check for dpf blocked 👍👍👍 cheers
Did u hear anything back from dpf ?
I was wondering if it could be a block exhaust. I have herd of the cat braking down and plugging the exhaust. it causes a similar issue and sound as the exhaust gasses can escape.
That’s a good shout , I’m not sure yet but we will probably time the engine and thanks for your suggestion I’ll check for dpf/exhaust restriction 👍👍👍 cheers
Wouldn't that trip a DPF pressure difference code?
It should give some error for dpf pressure but I scanned the car and no codes I believe we have a valve problem 👍👍👍
How's she goin'? This was a difficult repair. Great that you had access to a guy like David to extract the broken bolt. As you were trying to think of ways to get the broken bolt out I was wondering what caused the bolt to break in the first place. And then the engine was running and making that scary noise, I was more interested in why it broke. Then you mentioned the timing being off perhaps and exhaust not going out the tailpipe. Well it has to go somewhere and popping out the injectors is probably what happened. Good diagnoses Igor on a difficult problem to resolve. Take care!!
Hiya Mike yeah this one was quite interesting lots of development after I had the engine running , unfortunately It’s time to retire the old girl ... cheers mate 👍👍👍
@@CarsExposed Is the owner junking it?
@@ast5515 yeah he is replacing it now too many miles 👍👍👍
nice one bro xx
Thanks mate 😘🍻👍
How do you fix injectors cylinders for seat leon mk2 fr 2.0 Diesel
Something similar happened to my Caddy which as the same engine. In about 2019 two of the injector came out and the car was recovered. The idiots who "fixed" it just tightened the bolt down (which you should not do). It came out again a few days latter. They then claimed to have replaced the bolt but three years later the bolt they replaced snapped. They had almost certainly over tightened it. Took out 2 injects and cost me £600 the muppets.
ohhhh man I was hoping for some drilling and bolt extraction :) just kidding mate, glad you got it sorted, it looks like some massive back pressure there, you got a welder ? drill some pre and post holes and hammer in some brake tubing for pressure testing pre and post DPF :) that sucker has the symptoms of needing some Pepto bismol.... :P
🤣🤣🤣 yeah man I was hoping the engineer would be cool about me filming but unfortunately no... I haven’t got a welder but hopefully I should be able to measure the pressure removing the sensor in front of the dpf ... P.S. I just googled Pepto Bismol 🤣🤣🤣👍🍻
Do you think the reason could be over torgueing the bolt or bolts when the injectors were replaced? I had the same problem on my DS4 and even the brackets were broken! Then I read somewhere that 2 stage-torqueing is necessary like 7nm at first and an additional 50 degrees tightening.
I believe the main reason is injector removal and no replacement of the bolt. Some time ago he had the whole fuel system replaced paid by Tesco including injectors and I don't believe they replaced the bolts which is one time use.
Thanks dude.@@CarsExposed
great video!
Thanks mate 👍👍👍
Hi, did you found the cause of this? I have a Skoda Fabia 3 1.4 tdi and i had the bolt broken, 2 injectors out on the highway. I got the bolt drilled out and injectors put back at a service. The car seems to work for the moment, it passed 1 week, but now im afraid to make long trips with my car. People from auto service say they cant tell the reason why the bolt broke. The car have 215k km
They generally break if you remove the injector and don’t replace them bolts. The injector clamp bolts have to be replaced every time you remove them.
@@CarsExposed today my car made a sound like someone was trying to whistle and then cut the engine power a little bit. I was 2km away from home. By the time i arrived home the engine does not pass 2k rotations. The service is in front of my home, they checked for errors but not errors found during the diagnose, but the car simply does not have power to accelerate.
Great video Igor, what will he buy for a replacement for the old girl?
They bought a Hyundai IONIQ Hybrid today ... , nearly 500k miles later it was time to retire the old girl 😊👍👍👍
@@CarsExposed I hope my Superb that has 155k miles serves me that long :D
Yours has a long to go you should be fine 😊👍👍👍
Igor, yet another great video, plenty of good descriptions and camera angles are always good too so we can actually see exactly where you’re working. Such a shame I live so far from you, I think we all need a mechanic like you nearby. RIP Superb, she was a good ol girl
@@johnmc2888 thanks mate I really appreciate it , yeah she been really good until now 👍👍👍 cheers
Same happend today,luckily the nut wasnt too tight,went out with two screwdrivers.
Its VW saran 2013 do i need to reprogram the new injector(the numbers are same on the new one) ? 🤔
Oh no man ... well the injector normally needs to be coded now if it’s the same it’s ok👍
How long does a job like this typically take?
i’m wondering to buy one of this with 83k miles 1.6 tdi 2011, what do u think? should i buy it? i love the interior of this cars but i know a lot of people have problems with the injectors
Personally I wouldn’t buy one. I have seen so many issues that I don’t like specially oil leaks. But I have to agree they have a really nice interior. 👍
Might be good to check for any blocks in the exhaust system before doing all the work probably don't want to do all that work than same thing happens again learnt the hard way on that good video wants again tho keep up the good work
Thanks mate I appreciate it I’ll check the exhaust/dpf system 👍👍👍
I got the thing today customer brought me mk6 golf 1.6tdi cayc engine and I got broken bold that holds down injector 1&2. it’s been running the same little glmpy and killed 9 injector in courses of 2 years 🙄🙄.
Another thing i forget to tell you that Lookers skoda/seat dealers same stretch bolt if they go through seat system they sell for £7 +. If same bolt skoda system then £3.70 and same price £3.70 from vw.
Do the injectors need recoding as they have been out? Maybe mixed up ?
Thanks for the suggestion bud... I’ve numbered the injectors with a paint marker before removing them therefore no need for coding 👍👍👍
What’s the mileage on the car ?
How to change skoda octavia thermostat and flush whole coolent from system any video link plz share thanks
Unfortunately I haven’t got a video on that mate ... what year and engine is it ?
@@CarsExposed 2013 skoda octavia 1.6 dsg
Ah ok what’s the issue exactly?
@@CarsExposed so basically i changed the heater matrix as had heating issue after chnaging it was fine for week and then not getting enough heating when fan is on full blast only get heat when fan is on number 2/3 u get good heat when its on windscreen it wont get any heat .
Now trying to change heater matrix and thermostat but needs to flush the whole system so looking for how to flush coolent system and refill it so any debris in there will come out and get heating hope i clear everything.
Its causes by vw specialists when i took the car to them to fix secondary water pump underneath raditor bit they put silicone sachets in it and it burst inside and start having me heating since then and coolent overflow and keep loosing coolent aswell after couple of days now but engine oil is ok car is not over heating or anything so coolent is overflowing as i can see on coolent bottle marks of coolent overflowed.
@@syedsubtainhaider4785 have you driven the vehicle on a dual carriageway or motorway and noticed the temperature gauge on the dash drooping lower lower than 90°? I’m only asking that because there is a secondary thermostat on top of this dsg gearboxes just before the cooler ...
How much was the injector seals my mate was charged £300 with fitting on his 20 litre audi tdi diesel 54 plate
£300 ouch... The copper injector seal were about £6 each I needed 4 and the valve cover seal were £8.50 each I replaced 2 👍👍👍
Sad it was retired, poor girl.. is that a common problem on these engines sith bolts snapping ?
I don’t think it’s a common problem although Dave said he has done quite few of them but they normally break when torquing the bolt , Only one bolt snapped but I decided to change both just in case as it was pretty cheap ...
@@CarsExposed gotcha ok, should the bolts be replaced as a maintenance thing, wonder if they snap due to age.. then again if its not broke dont fix it I suppose
I wouldn’t worry about it unless you have some work done where the injector will need to come out then definitely replace them as they are stretch bolts ... this car had the whole fuel system replaced £7500 of work (I don’t think they’ve changed this stretch bolts) around 3 years ago after filling up with what should be diesel at the local Tesco station , Tesco on that day had the underground tanks cleaned and they left some sort of paint stripper behind which damaged a lot of cars that filled up the tanks on that evening over a million pounds worth of damage that Tesco paid for everyone ...
@@CarsExposed jaysus feck sake, least tesco covered it all, I dont knkw previous history of my car so was just wondering. Its going in to skoda tomorrow for timing belt and waterpump, maybe I should ask them to change the bolts, or feck it leave it
@@ronangsr www.bbc.com/news/uk-england-dorset-35484180 here is the news at the time ... but ended up being hundreds of vehicles repairs and replacement cars bill...
Well it’s hard to say I don’t think it’s a common problem personally I would leave it but you can always check with Skoda the price and everything my only concern is if the technicians will follow the procedure properly changing the bolt ...
Which is with the engine this damage. i have the same 2.0 TDI 125 kw. CBBB code. It's a great car.
I’m not 100% yet but I believe there is some valve damage ... it has been a great car here aswell nearly 500k miles
@@CarsExposed What is the engine code?
@@berykent4598 cffb
@@CarsExposed thanks
Great video mate,what tool did you use to extract the injectors please as I believe one of my rockers has snapped so I have to take the injectors out to get the rocker cover off and mine is the cffb engine with 340,000 on the old girl.
Thanks
Thanks mate , I didn’t use any special tool in this case I just removed the fuel line and put a socket that fits over the fuel inlet connector with an extension and started wiggling the injector bit by bit and it became loose but they can be a right pain 👍
@@CarsExposed thanks that information I will give it a go as I can’t get a mechanic to do it after somebody replaced the water pump and timing belt it won’t start and suspects a rocker has gone 😬 Tanks once again for your help and keep up the good work 👍
Cars Exposed Thanks for your tip regarding the removal of the injectors as it worked a treat 👍🏻,could you tell me if it would be possible to replace the Brocken rockers while the cam is still in place.Thanks for your help.Chris
@@skywalker070369 to be honest I haven’t done this job before mate sorry
Cars Exposed No problem and thanks again
Auto data states 8nm + 270 degrees
I wouldn’t dare to go that 270° , I’ve done quite few like the procedure showed in the video with success much more than that I feel like something got to give 👍
@@CarsExposed I do exactly the same as you mate 270 is way too much 180 feel like it’s on the edge haha
Have you got daves number
It is in the video description below 👍
