Hi

I wonder if anyone else has experienced this or can advise...

Since engine replacement (short engine) I have noticed a chain like noise from the engine. Typical scenario is, give it some power in 2nd or 3rd gear come off the accelerator completely. As the car slows itself down the car makes this chain / buzzing metallic noise as it drops between 4000 and 3000 revs for about 2/3 seconds. I say 2nd and 3rd as with road noise it's hard to hear above the speeds these gears allow. It always seems to happen at this particular point in the rev counter and doesn't sound smooth as it should.

My nearest dealers junior technician agreed there was a noise there and said it didn't sound normal to him. I took their "master tech" out who I was suprised to see was only young himself and although I made the car make the same noise he said he could not hear anything and accused me of "worrying too much". Despite doing it over and over again and making the noise he wouldn't open his ears. He said he had done 33 engine replacements and that he thinks he knows them inside out. Now seeing who done the job I am even more concerned...

They took the car in and plugged it in and apparently checked the engine mounts and couldn't find any faults. I said to the service manager what about mechanical faults which wouldn't log a fault code. He said well you need to demonstrate the fault and that his senior guy can't hear the fault his junior and I have... Round in circles.

I took a friend out who is also in the trade and he said it doesn't sound right and sounds like the chain is either a little slack or there could be an issue with a tensioner causing it to rattle slightly at a sweet spot in the revs.

I then went to my next closest dealer and made a booking for next week (27/05/14). I then took there vRS demo for a spin to confirm that it was or wasn't normal. The demo did not make the same noise.

So any ideas on this or advise?

Appreciated as always.

Skoda UK have said via Dan Wilson. They do not supply short engines.it is remumufactured engines.

Dan Wilson? I noticed a yellow sticker on the left side of the engine the other day which is written in German apart from the bottom line saying made in Germany. I will have to translate the other words and find out what they mean.

Dan Wilson deals with fibs when Tom Chadwick is off and Alasdair Stewart is running skoda uk

Professional bull ########'s

As they say, "none so deaf for those that don't want to hear' ..

Just posted on MattGreens thread "Lumpy fast idle following misfire" as mine ran rough like his video this morning.

Thanks for input above. I guess the technician doesn't want to receive any criticism for his work...

My car does exactly the same thing as you let off the throttle. Seems to be only for a short time, could it be something to do with the supercharger belt? I'm never really sure when it disengages. This is also a replacement engine for me, I can't recall if the original did it too but it might have.

It's strange how ours do but others don't and also strange how both of us have replaced engines. It definitely doesn't sound right to me. The engine should run smoothly especially running on 99 octane fuel...

 

My original engine definitely didn't do it and the noise is new to this engine. Combined with the rough running and rocking on the spot start ups there is something not quite right with some of these engines.

 

As I have said the demonstrator I tried at the weekend didn't make this noise, however I noticed that on a short 5/6 mile run the oil temperature rocketed up to above 104 degrees celcius just with a quick blip up the motorway and back. The outside air temperature was about 18 degrees. My cars oil temp was sitting comfortably at 85 degrees having done similar miles to the dealership. The demo also felt less responsive and not as quick, possibly from being run on 95 RON fuel? The chap in the service department was more concerned about me not doing too many miles and going too far in their filthy demo car than the issue itself.

 

I've been in touch with Tom Chadwick and Alasdair Stewart again this morning.

 

With the dealers adamant you must demonstrate these faults something which can sometimes be difficult as they are intermittent and other times when you do demonstrate them and their technicians play deaf. How on earth are you meant to get things sorted...

My suggestion is.

 

'Ask the SKODA UK Customer Services to talk with SKODA TECHNICAL EXPERTS, about the Remanufactured CAVE Engines with CTHE parts,

& the ECU & ECU Upgrades - MAP,

is the Engine Management and Fueling actually Correct, ???

Do the Technicians Fitting Replacement Engines need to Code the ECU, Install Updates or the likes?

 

Why do Skoda UK not get a Master Technician & a Factory Technical Expert to check the Installation of your Replacement Engine  - Vehicle

& see if there are Problems with the Units, Remanufactured Engine/ECU or Dealership Installations?

 

Seems Simple enough, & all good knowledge for them,

since there are quite a few issues with replacement Engines in the UK.

 

Vorsprung Durch Technik as it should be applied.   'Learn through their failures'.

A littel off topic here guys but do any of you have any sort of contact information for Dan Wilson or Tom Chadwick? I've searched up and down google but can't find anything on them!

You address your communication to,

For the Attention of,

Alasdair Stewart Brand Director Skoda UK

VIA Skoda UK Customer Services,

so  For the attention of, by Email, Registered Post Royal Mail, or a Solicitors Letter gets their attention.

They can get back to you.

 

If you are unhappy with the person at Skoda UK Customer Services that has been assigned to you,

best ask to have someone else to talk with you,

go through the current situation and the stance being taken by Skoda-Skoda UK.

Be sure to get everything in Writing from them.

 

Trading Standards & Legal Advice will really be required if they are refusing to deal with the known problems with the Vehicles and Engines they manufactured.

Sure enough when I started her up this morning no rough running! Nice and smooth (well as smooth as its ever been). Then went on to change the plugs, which was definitely an eye opener! Firstly I made a coil pack tool using a coat hanger which worked ok but I would get a tool if Im going to be changing plugs regularly. After much fiddling with the Drivers side (#1 cylinder I believe) all plugs were removed to find them dirty and covered in what can only be described as mould (I know it isn't, but it looks like it) I will try and get more pics with my camera at some point. 

 

Car seems to run smoother at pickup and when pulling away from a stop. Time will tell if it has made any difference to rough starts, economy etc. but I'm sure its not going to affect the rattle noise. 

 

What sparky's did you change them for?

daz1412,  

when they install your new engine it will have new plugs in,

while it is drinking oil, you could change the plugs if they are in a bad way,

i would not bother,  best get Skoda onto getting the engine replaced. 

I'm keeping onto them as much as I can without being a pest. they're promising calls which I never end up receving! yesterday the lady told me she would ring back in 10 minutes and still never called back. It's getting a little beyond a joke now and the oil consumption is getting worst and worst. At this rate It could be months until I see any progress what so ever. I'm having to hire a work car at the moment as I can't even take her on long journeys.

 

so if changing the spakrs means it makes the problem better by just 5% then i'll do it cause I feel that my chances of getting a new engine are next to none.

I put in some NGK BKR7EIX which seems to be the common plug of use around these Brisky parts. Managed to get a set from some guy doing a shed clearance for €20, bargain. Glad I did now! 

 

Best of luck with the engine though mate, I know it can be a pain in the behind. Hope the tips you get for Skoda will help make the process quicker!

daz1412,  

you would be better spending £40 for a Free First Appointment with a Solicitor & then get a Letter off to Skoda,

than buying 4 Spark Plugs.

 

You said before that your mate is a Skoda Specialist, can he not check the Spark Plugs.?

I can check spark plugs myself, will do it tomorrow!

 

Praying to god that I dont have to go down the legal route, time will tell!

daz1412 - if they are making promises and not sticking to them then you should bring your case to the attention of Alasdair Stewart (or his team on PA's) if you haven't already done so. It seems to be the only way of getting things moving with Skoda UK.

Just to keep this updated. I've finally got my car in the dealers. Took a technician out to demonstrate this noise. His initial thoughts were that it is transmission related as it only occurs when in overdrive. Can someone explain what he means by overdrive?

It occurs after full throttle (not hitting the button under the accelerator - overdrive??) when the car winds down just under 3500 revs.

There is no overdrive so that was guff from him.  (He maybe meant Overrun.)

 

The Supercharger can be on below 3,500 rpm, engaged on demand,

so above 3,500 the Engine has Turbo.

So maybe Supercharger engaged and disengaged.    or just the DSG.

 

?

So is it still in 7th, decelerating,  

off the throttle, and dropping the revs to below 3,500 rpm?

 

No idea what it is, but i have told you that before,

 i do know

'Overdrive has nothing to do with anything on your car'.

 

Them replacing the Engine probably has,

so they should maybe get a Skoda Special Technical Team Technician in.

 

??

Did you say before they said your DSG had the Service Campaign work done,

Mineral Oil in the DSG and the ECU update?

Their conclusion - it is the way I drive the car... Apparently.

No it hasn't had the oil change campaign.

The technician said it sounds transmission related but no says he has run a diagnostic and can't find a fault. They are not prepared to do anymore. What about mechanical issues which wouldn't log a fault code... To which they said you will need to take that up with the dealer who completed the engine replacement.

Only noticeable in 2nd and 3rd gear but maybe muffled by road noise at any higher speed.

Their conclusion - it is the way I drive the car... Apparently.

Oh right. Its your fault then. What a surprise...

Basically, he doesnt know.

Best check with Skoda UK if your vehicles VIN shows it requires the DSG Service Campaign Field Action.

 

Obviously the Engine is replaced, but if it has the Original DSG,

they should know if it needs the Synthetic Oil Changed to Mineral., & the ECU Update.

 

When that is being done, hopefully a Fully Trained Technician can check the Mechatronics Control Unit

is not also needing Replaced.

They are not Cheap, but all the New Zealamd cars had that done as part of the Skoda NZ Sevice Campaign

(Recall) and as far as i know, these are the same Gearboxes,

used in a similar environment.

 

That Tech can then Road Test the car after the DSG Field Action.

The Engine Replacement is Covered by Skoda for the Warranty,

if they can not find Qualified and Competent Skoda employees to diagnose faults on Engine Instalments,

or with the VW Built Gearboxes,

they will just have to Commission Independent Gearbox Specialists.
