Is it worth to repair? 4 Injectors gone, high pressure fuel pump, probably engine compression issues...

I was told fuel filter is ok to change on every second oil change. So it wasn't changed with the recent oil change last week.

You had me googling in excitement for a while though, I am currently selling my UK property and will be transferring the funds into Euros.

I really don't think in Euros, so while I was slightly surprised to misread the 1.9:1 rate, it didn't ring any alarm bells for me. 😄

As Ecomatt says, Change the filter & look for metal in the bowl, If clear get the actual fuel pressure checked. Any Competent diesel guy can do that even in Kerry !!!

I used to live in Derry nane on The Ring 

I wish I had a place to make these tasks. I don't have any private place to make myself busy with my car.. 

 

Actually I ended up in situation where I can just wait for results. Should be major update tommorow. Lets hope for good news.

 

Anyway it won't be cheap, I already prepared myself for that. Just sad that 4 years old car can break so hard.. Really didn't expected that. 

 

[Client76]

In other words I'm giving up - will let do wathewer they think needs to be done.

All my knowledge about this repair mainly from this topic. Good chunk of info, but definitely not enough to make wise decisions by myself. So, thanks for all ideas, and suggestions I'll keep you updated when repairs gets done. If someone interested for results.

Good luck with your Octavia. Interesting read. I have similar car on 62000 miles. Always good to read about owner experiences with same cars. 

[Client76]

Ok. this not really an update but thats where I'm at. 

From now on I won't be dealing with an offcial dealer (at least for this matter). All below will be related with independant garage. As dealing with dealer garage could cost me half a car 😄 Dealing with a private garage is a pain, everything moves slow (but way cheaper) 

What I have today:

• One injector dead, so had to be replaced.
• Unable to check engine compression because of something (I'm  not an advanced car guy). They can't remove something from the engine to check it because part need to be removed is burnt in to (engine?). By forsing to remove the part there is big chance to brake engine head (or something like that). So this check (compression check) has been moved to the very last step of repair if nothing below helps.
• Rest three injector were cleaned and was ok on testing site. Appears one still not good enough. (Thats pauses all the works for  few days). 
• Man who cleaned injectors spotted a metal particle in it. 
  • The is a thing: independant garage contacted official Skode dealer, and official dealer suguestion was to replace the whole fuel system - from fuel tank to high pressure pump part only about €5000.
• We agreed just to clean the wholefuel system which saves a lot of money.
• If all good after that should be able to escape form garage with €2000 bill.
• If not - back to engine compression issue. Fix that and happy days. (for how long?) 

Basically trying to fix broken parts instead of replacing with new ones. I just could imagine official dealer taking 3000 thousand and then saying oh wait, we need 5000 more for aditional parts and also will charge you for work and on top of that we need to replace two more injectors thats one more thousand to the bill. Thats (over 8000) already a half price of the car... 

 

PS. Just caugth myself on this: Advert: Car for sale, plenty of extras, running like a clock. 😄 Really considering that option. As most parts will be fixed (not replaced in to new ones) wondering how long I will drive until it happens again... 1 year, 2 years?...

I forgot to finalise this story. I had two injector repaired, two brand new. Also cleaned all fuel system cleaned, fuel pump repaired. I believe cleaning fuel system was a scam, but anyway. I was told that man who checked injectors found a microscopic metal particles, so they can appear in the fuel system aswell. I asked how did you cleaned the fuel system? He said "Oh... we cleaned the whole tank with clothes, and blowed the fuel pipes with compressed air". My thoughts: microscopic particles cleaned with a cloth? Blowing? Really? Even particles are in the fuel system, then what is the purpose of the fuel filter? 🤔 But anyway. That's the end of this story. Problem solved anyway. Even if suspect garage scam.

[J.R.]

It's not the end of the story, you have not said if the compression test was good, if the car now runs, that you have had it back for a week or two and everything appears fine.

 

[Client76]

Oh.. My bad 😊 They didn't run a compression test as injectors solved the problem... Testing compression was in the case if injectors and fuel pump will not solve the problem. And I'm kind of happy they didn't check, as there was some sort of problems with checking compression. With engine head. They can't remove something from engine, it was burnt in to it or something like that.

 

Have to admit a few things: As I said I have no experience/knowledge about cars in deeper level, and english is not my native language. That's why I struggle to explain some things about compression (because I struggle to understand what they told to me 😜) 

 

Anyway, everything was fine, but alternator bearing gone in a few weeks, had it replaced yesterday and today I got another problem 

That wobbling hose... what the purpose of that hose? She is vibrating very hard, and on about 1000-1100rpm making really loud and scary noise.. Wondering can I drive to work tommorow..

I'm really "lucky" skoda owner...

Been a while and I'd need to trace it but is that a water hose? Vibration looks normal to me. If the natural frequency is about 1k revs you should be ok as most of your driving will be above that. Do any of the hard lines it's connected to have obvious play?

Diesel in oil = DPF regen issues

 

Not always the cause but was a sign of issues in older/different brands.

 

Or injector seals.

Metal particles will normally be from the high pressure pump breaking up, so after the filter, but they can go back to the tank via the return hose. 

 

Modern diesel can get algae growing in it, so giving the tank a wipe out can't hurt and might make your lift pump last longer.

My understanding is that if all excess of fuel going back to the tank, then same fuel will go trough the fuel filter again.. Unless the fuel filter can't filter these particles? And yes you right and I agree with you high fuel problem was the main reason of the problem. Just thinking what the fuel filter able to filter then... 🤔 Never heard about algae. So, if that's done for sure - at least for good then 🙂

Frame rate in the video ruined a video. (Same as you see propelers of helicopter not spinning on the fly) In reality it is crazy vibration just above 1000 rpm up to 1100-1200. I spotted it on highway traffic when had to slow down from 100 to about 60kmh and then had to keep that speed. Didn't happen for rest driving until get to town and then same moving off at roundabout or traffic lights. So stopped at parking to investigate. Wife not good at keeping revs even, so not easy to spot on the video again. Best moment to spot it somewhere about in 35th second in the video. Hope I'll be ok for today's work-home drive. My garage almost across the street at home 😃 

 

Sorry didn't get that part of question.. "Do any of the hard lines it's connected to have obvious play?" 😵‍💫😊

The returned fuel will get filtered next time it does round. The stuff that gets sent to the injectors won't get filtered between the damaged pump and the injectors.

The hose looks like an air conditioning hose to me with the crimped end and what looks like aluminium solid sections.

 

If you trace the solid sections back and forth you should see a test connection port which should be covered by a black cap, if its been in the garage its probably missing.

 

I think it is probably missing a fixing on a retaining bracket but could be a pump problem, does the noise stop if you turn off the AC?

[J.R.]

I can see the test port on the pipe just in front and underneath the one in question, I reckon it is air con.

I'm trying to get out of the habbit to abandon discussion without updates, but still keep forgetting to come back... I took car back to service next daybor so, told and show what's going on. Man took all the cars out of the garage, got mine, lifted and tighten something. I've asked how much for the fix, Mechanic offered some coffee for me instead 🙃 I didn't even asked what that was. It took literally 2 minutes. He probably forgot something. 

To complete your answer - no, AC on/off didn't make any difference. And I didn't checked hoses as you suguested, hadn't enough time, and later forgot about it..

I'm not sure about it.. AC on ir off it didn't made any difference. If I remember right worse was in betwen 1000 - 15000 rpm. Normal driving didn't cause any vibrations. Anyway, it is fixed by now 🙃

[Client76]

Even my repair story is ended. Few days ago I got the very first signs of problem coming back. Nothing major for now, just slight shake on cold start.. But I know where it will go in month or two... Really considering change the car...
