I have hunted around here and can not find a direct injectors thread.

 

In a few other websites and possibly here I have seen that Skoda injectors have been giving problems and in about 2011/2012 they were recalled for replacement.

 

I have had my first external service outside of warranty. 3 years or a billion km... or whichever comes first and the mechanic immediately rang me and said the noise of the engine is pointing to injector problems and possible failure. He says he has a spate of fails coming in recently across many brands not just skoda.

 

I am driving a superb registered in early 2012 (possible 2011 made) with a miserable 65,000 km on it. I am trying to deal with skoda Ireland to see what fall back I have on this. I am officially out of warranty but curious if anyone here as part of this emissions scandal campaign has had their injectors changed out.

 

My injector code is 03L130277B

 

Thanks.

There isn't an injector switch out as part of the emissions recalls.

 

The 2.0 EA189 engines are software only - as are the 1.2 EA 89 engines.

 

VAG mooted an injector replacement for the 1.6 EA189 diesels in the early days of the scandal. They then backed away from that and say they will propose fitting a flow rectifier in from of the MAF instead.

 

The final, definitive fix for the 1.6 has not been officially agreed yet - it is only stated that it is expected "soon". The flow rectifier solution is still with the Federal German Transport Authority (KBA) awaiting approval (stated in the press yesterday when approval for the 1.2 fix on 460,000 cars was announced).

Hi robink. This is about the injectors not the emission swap out. Different post.

Are these injectors good, bad, on recall, ever recalled? Why are they failing after 4 years 63 k km. I have a Skoda Octavia 2005 with 190 k km and never any trouble with it. :(

The injector recall was for the VAG "PD" Pumpe Duse 2.0 diesel engine where injectors were shorting electrically causing the engine to cut out - not good on the outside lane!

 

Your injector code is for the later VAG "CR" Common Rail diesel - totally different engine - I think?

I'd be very slow to spend 2 grand on injector replacement based on the mechanic's opinion of the engine's sound. Take the car to an injection specialist if you think there's a problem with them and get them to test the injection system. A quick search on google suggest 2 or 3 options in Dublin.

 

Poor injector performance could as easily be a problem with the high pressure fuel pump, the common rail, any number of sensors, etc. Replacing all of those until you fix the problem is going to be an expensive game. You're better off paying for a few hours diagnostic time at an injection specialist and go from there.

I not heard anything from the trade about 2l injector problems, at least nothing more than any other brands. Get it scanned before doing anything and see what shows up. There's a lot of low quality fuel around at the moment causing fuel injection problems, stick with a reputable brand.

Sorry - I saw you mentioned an injector swap out as part of the emissions campaign and thought you were asking a similar question.

 

As mentioned above - there was a recall on injectors for the Superb for the 2 litre "pumpe duse" / PD version of the engine. One of the members here, silver1011 I think, said the injector recall screwed up his car worse than the fix it was supposed to provide...

 

From the part number you posted, I think you have the later common rail engine as that is a Siemens injector for the 1.6 diesel.  If you could post your engine code (should be in the service book and/or on the sticker where the spare wheel is kept) then we can be sure what you have and someone may be able to point you at any known issue. If it is the 1.6 you have then the code is probably CAYC (fitted from 2010 onwards I think - the 1.6 CR / TDI engine replaced the old 1.9 PD / TDI on the production line).

 

That said - I'm not aware of any specific problems with the injectors except where people used bio diesel or were unlucky enough to have used contaminated diesel. You know yourself, there are 1.6 litre VAG diesels being taxied to huge mileages all over Ireland and your car is pretty low on the mileage side. 

Thanks. Yes the car is a superb elegance ecoline 2012. 1.6 l engine. CAYC is the number. Mechanic has serviced it and will arrange diagnostics if I want to proceed. Its a nasty ta ta ta as I accelerate. He had it for a test run as I came to collect it. I heard it from around the corner. :( its fine apart from that.

I would prefer to find a reason why these are failing. Perhaps it is cheap diesel! We try stay large brands but the cheapest of those.

Exhaust manifold? EGR valves fail on these engines and are a pig to replace. If replaced things could have been mis-fitted

It has not had any work done on it yet.

I dont want to open a new topic so i write here.

Could anyone noticed an engine noise for cr170 ?

I have more rattle diesel engine noise for the first run in the morning , but after some minutes drive and restart it is much smoother, called perfect diesel noise

I can reproduce this nearly every morning....

I read something similar before but can not remember where and what was the solution....

This is normal for this time of year as the temperatures drop, it got down to 2 degrees Celsius here yesterday at 06:00am.

 

I've noticed fresh oil quietens my CR140 down during the first few minutes after a cold start, more noticeable in the winter.

The only injector issue I'm aware of is with the PD170 engine fitted to the MkII Octavia vRS. A VOSA recall saw a lot of VAG cars get new injectors and wiring looms.

 

Unfortunately my dealer screwed the change up, diesel fuel leaked past the new injectors and diluted the engine oil. This then very quickly killed the DPF and three turbo's in quick succession.

 

Cold starting became a huge issue too with extended cranking required and rough running. Then there was the hidden damage from the degraded engine oil.

 

This issue at the time wasn't isolated either, lots and lots of other members experienced one or more of the symptoms I suffered.

 

All in all a complete disaster. The only positive was selling the Octavia and getting into the Superb!

Sounds like the mechanic needs the sales...

But the point is that after restarting the engine (still cold after 2 minutes run)), the clank from the engine during acceleration is not any more there.

In other words, the restart in a short way is smoothening the engine noise.

I agree with Silver above.  This is normal.  I've had this on both the 170s I've had  Very noisy on initial start and very quickly quietens down and is very temperature dependant

run some Forte through em

Even after 2 minutes running the oil is now warmed slightly and has been circulated up out of the sump and around the engine.

 

This is why the second cold start isn't as noisy.

 

Assuming the first cold start is first thing in the morning then it is likely the engine oil is all sat down in the sump, it's had the best part of 12 hours to settle.

 

The older (thicker) the oil the harder / longer it takes for the pump to circulate it around the engine.

Okey i understood but one more thing, that if i not restart my engine , the noise is nearly all time available until i restart. Thats why i feel it could be some problem.

Why would hot/cold oil make any difference to injector noise?...they arent lubricated

I dont know, maybe it is not injector, just placed this discussion here;)

It doesn't, the thread is old and was revived. I wasn't answering the OP, but post #12.

Mine is also quite noisy until the engine is fully warm, in the winter it can take several miles before the thermostat reaches 90 degrees and the oil temperature (via Maxidot) gets anywhere near 100 degrees.

 

The noise I would describe is a clicking or 'tapperty' noise.

 

During my lunch at work I take a walk around the block, I can always tell a VAG 2.0 TDi engine approaching from behind, they have a unique sound when cold, even more so when listened to from outside the car.

These engines have hydraulic tappets which can be a bit clackety when cold. That said, once the oil is up to pressure after startup they should quieten down pretty quickly.
