Hi there, we bought a 2nd hand 4 year old Skoda Yeti 18 months ago. About 3 weeks ago there started a banging/ticking noise from the engine. VW garage (Skoda had disappeared) said we needed a new flywheel clutch and timing belt. £2000 please! We are not wealthy people. Took it to two local garages who quoted far less. 
so, work completed. Same noise as before HELP. This effing car will bankrupt us. Any ideas?

Did the local garage who did the work hear the noise and also diagnose the clutch, flywheel, timing belt etc. or did you just give them the car and tell them to do the work?

We told them as 3 mechanics had already said what it was. This garage said if they’d heard it they would have said it was the flywheel etc. 
Apart from”’oo said what to oo” any ideas on the noise front?

So has the clutch, flywheel and timing belt been replaced and you still have the noise?

Would help if you said what engine your Yeti has.

Nobody can have any idea what a noise is just from a description of banging/ticking, you will need to be more specific, engine type, where approximately the noise is coming from, under what conditions, revving, idling, driving, accelerating, over-run etc.

 

The ideal would be to post a video with sound from a mobile phone.

Hi Kenny, it’s a 2L diesel. Yes they’ve all be changed.

JR it makes noise under all conditions but particularly when accelerating. Can’t post vid as car is in garage. Rather inconvenient as we live in the back of beyond with no public transport.

You said originally a "banging ticking noise".  Did the problem start quietly with a ticking noise and progress to a banging noise or was it both from the start?

 

Has there been any loss of performance?

 

Same sort of noise from start. Husband informs me that if you open bonnet the noise is horrific. No loss of performance. Thinking of just scrapping it as we can’t throw good money after bad. Will NEVER buy a car with a VW engine again!

It’s probably going to turn out to be something simple and a cheap fix, but you throwing  money on a cambelt, clutch and flywheel that wasn’t required doesn’t make sense, especially your last comment.

Our mechanic just got back to us. Not a cheap fault. The car is ****ed. Balance shaft bearing support unit. Known fault. Legal battle begins but thanks for your input.

@Insectwoman Sorry to hear,

but who is the legal battle going to be with on a used car bought 18 months ago?

?

How many miles on the car when you bought it and how many miles now?

Should that not be never go to anybody that cannot diagnose the fault and just changes expensive parts until they get it right.

Get some balance!
In the 11 years I have been involved with Yeti's I have never seen that fault reported, so how the hell can it be a "known fault"?
 

Legal battle over a 5 year old car bought second hand 18months ago.

 

Good luck with that one.

If the Legal Battle is to be with whoever did the Timing Belt which was due a change and the Clutch & Flywheel which might have needed doing and after being removed should be showing if they were needing replaced.

So you tell a garage what work you want them to do because other garages have said that is what is causing the noise, the noise remains so you take the garage to court for doing as they were instructed.

 

Glad I stopped working for customers when I did.

Perhaps it's time to cut a little slack and allow a rant, I've even been known to say things in haste myself and been wrong 

In case it helps understand the balance shaft function: 

 

"Two cylinder block housed balance shafts are used to counteract unwanted vibration at engine speeds above 4000 rpm from being transmitted to the car body.The balance shafts run at twice the engine speed in opposite direction from one another. The direction of the second shaft is reversed by an idler gear. The horizontally staggered arrangement of the balance shafts also helps reduce vibration.The balance shafts are made from spheroidal graphite cast iron and run in three bearings."

 

In essence, these are rotating eccentric iron weights which produce a vibration equal and opposite to the engine's secondary vibration, which therefore cancels it out for smoother running.  This refinement in engine design tends to be used for larger capacity 4 cylinder engines, and has been around since Lanchester invented it many decades ago.

 

The shafts are buried fairly deeply within the cylinder block, and are normally a reliable component unless there has been a problem with the lubrication of their bearings.

It seems there was once a problem with balance shaft bearings on vag diesels - but on PD engines as used in Skodas made before the Yeti (that uses a CR engine) was born.
