A lot of hate for KW&Halfords. Understand the hate on kwick fit but only ever had great service from Halfords. (Even got a discount)

go to a local garage, maybe recommended on the good garage scheme? I refuse to take my skoda to skoda for repairs due to the huge cost compared to independent garages using skoda parts at a much lower price!

Suspension noises are very difficult to diagnose from just a description of crunching over rough surfaces, now if it was a knock over bumps then we would say its the drop links or anti-roll bar bushes, but crunching could be any number of bushes or the springs/shockers themselves.  I had creaking over bumps in my Hyundai and it was just ARB bushes that needed lubricating. I also had creaking/crunching on a Honda which was a wheel bearing that needed tightening up, so many possibilities.

There is a half decent garage near big John's on the ring road in brum, under the railway arches on the way to the blues ground.

Take it in there if you can

Thanks that is interesting read however I have a feeling that the mechanic will say that all these possible causes will need to be replaced unless someone on these forums with knowledge of Skoda cars can guide me that this possible cause 90% likely and other possible cause is 70% likely so I know mechanic wont cheat me. Like I said I am not after a 100% Diagnosis online. You gave me a list of the whole suspension system that if I take that list to mechanic meaning £££ for the happy mechanic. If I go into the garage armed with knowledge then mechanic will think twice before pulling a fast one.

Can you provide a link that they are backed up by good customer reviews online? I am only interested if they backed up by good customer reviews.

Not all garages are "Rip-off Merchants"! 

 

There's some recommendations here:-

My experience of the VAG specialists in Nottm has been very positive and I see no reason why the good folk of the West Midlands should be any different. I have found the garages I've used to be very knowledgeable and professional.

I can see on skoda dealership invoice that both rear damper gaitors have been replaced last march. I assume the previous owner took it to the skoda dealership for this problem noise and dealer did this replacement however its not the rear damper gaitors.

 

Are official dealerships that bad?

 From what guys are saying possible broken spring/s. Could also be a rubber bush on the bottom arm that's worn as well

This is the second thread that you have started that has gone the same way as the first one. Throughout BOTH threads you have been advised to seek professional advise from an independent (that is NOT a main dealer)

 

The reason for this is that a VAG independent knows the cars they are dealing with, and will not risk bad publicity by doing shoddy or dishonest work. Dealers are well known for trying to pull the wool over the customers eyes, and will have no morals at all about charging for doing just that.

 

Without sounding disrespectful, your car is 9 years old, and as such has 9 years of use and mileage, and it simply isn't cost effective to use main dealers for repairs on a vehicle this age. I have two Octavias, 7 and 10 years old, and neither of those will ever see a dealership again as far as repairs or service goes.  You have stated that you are not clued up about cars, and as such, the dealers would not hesitate in ripping you off -- many, as yours has, will even charge you a "diagnostic fee" of nearly £100 just to look at it -- and that is before they have removed so much as a wheeltrim! You REALLY need to find an independent and learn to trust them -- I certainly wouldn't rely on dealers unless your car is covered by a Skoda warranty.

 

Also, as I posted on your other thread, it is impossible to tell you what is wrong without seeing your car -- any mechanic or person who says they can diagnose a problem like this without seeing it for themselves is a liar, and could well diagnose it totally wrong with the result that unnecessary money is spent. 

 

If you told us that your car had a flat tyre, and nothing else, then that could be caused by a puncture, a leaking valve, a badly seated or damaged or corroded rim -- nobody could tell you what the issue was. But if you told us there is a nail in it, the problem  can be diagnosed straight away. Without SEEING what the issue is, you simply cannot suggest what is wrong, and that is where someone who knows what they are doing comes in. We are all on this forum for one common purpose, that is to help each other where we can with a view to saving money. And that is why you are constantly being steered towards an independent rather than a main dealer.

The only reason I booked an appointment at the dealer because the new parts the dealer fitted are still under the 2 year warranty otherwise I wouldn't go to them plus I cant see anywhere on the skoda terms and conditions of a £96 investigative charge for warranty claims. If someone can show me this I will cancel the appointment at the dealers.

Edited 21 March, 201511 yr by Laureen1979

Another question.  When the parts were fitted and a two year warranty given,  did you own the car at the time? Or was it a previous owner who paid for the job to be done? If the job was done before you got the car the warranty probably wouldn't carry over to you as the new owner, unless the job was done as part of an official manufacturer's recall.

 

What mileage has your car done? If there is a big mileage on it you can absolutely guarantee that the issue will be older original parts being worn rather than new ones fitted within the last two years - parts with no warranty anyway.

My car has done around 83000 miles.

Don't feel comfortable going to a garage after what I experienced from kwik fit. I feel more confident if I know what are the likely causes of a creaking/crunching noise when going over speed humps so I can say this is the possible problems so mechanic cant say I need new this and that unless you can vouch a trustworthy mechanic in my area. Please list the causes of these noises and we can rule out one by one. We already ruled out broken springs as I did that test suggested above. Please advise.

Kwik Fit isn't really a garage - it's a supermarket where you get your car fixed.  I've worked for similar establishments in the past and they quote the worst case scenario & hope you'll get some of it done.

 

 

As others have said, find an independant VAG specialist in your local area.  You could even post a thread asking for recommendations as that would be more useful than a lot of your other threads (sorry, I realise you are trying to learn but you need to know the actual problem before asking what parts to buy).

 

There is absolutely no point buying parts & going to the garage & saying "fit these" becuase the next conversation you'll have is "you didn't fix the noise I diagnosed on the internet".

Been to a local garage few days ago for this issue. When they put it on a ramp and lifted the car up I can notice the rear passenger tray cover is hanging a bit loose due to fixings/screws not there and they must have fallen off. Garage said they don't have these fixings/screws in stock.

 

What are these fixings/screws and where do I buy them from?

Hi there - does the crunching noise go when it is raining?

 

If so I'd bet it's the rubber bushes in the suspension that are dry and just need lubricating with some spray grease.

 

Easy to get at without any dismantling - just put the wheels on full lock, look for where the bushes mount to the chassis and given them a spray with some spray grease (making sure you don't get anything else like brake disks at the same time).  then do the same on the other side, reverse the lock and do the others you can see.

There are no fixings as such. The tray simply fixes with screws to the wheel arch liners at the side (4 each side) and 3 screws at the rearmost edge which go straight into the subframe.

 

For the garage to tell you that they don;t have the fixings and screws in stock is ludicrous. As said there are no fixings to buy, and all garages carry screws and bolts of different sizes. You certainly don't need to go to a main agent of garage to buy those!

 

Mike

 

Ok the under-tray covers fitted underneath my car. Can I just tell someone to take them off? Do I need them? Why are they attached to the wheel arch liners? How do I prevent screws falling off again? Thanks,

Laureen1979 - can you confirm exactly which bit you noticed was loose?  Posters here seem to have interpreted it as being the engine undertray, which is obviously fitted underneath the engine at the front of the vehicle - but this doesn't seem to tally with your description of "rear passenger tray cover".  I'm a bit confused.

Yes it looks like a engine undertray cover but at the rear. Just the passenger side of it is loose. If someone can link a pic/diagram I can show which one.

It is not really ideal to remove the tray, because once it is in place it holds the front wheel arch liners rigid.

 

I have never known the screws just falling out.  The only two reasons they will be missing is either the tray is broken or the screws haven't been replaced when the tray has been removed in the past at service. 

 

The only fixings are simple metal clips which slide over the edge of the wheel arch liner which allow a self tapping screw tighten.  They are called speed nuts and every garage in the country should carry these. 

 

Mike 

Ok from what I understanding the speed nuts are the fixings for the wheel arch liners and normal screws for the engine under tray covers?

sorry I meant its not the edge of the tray towards the rear wheels, its towards the rear by the exhaust.

As the weather has improved I noticed that the crunching/creaking noise is gone as I couldn't hear it recently . From this can we rule out the coil springs?

Could've just been your brakes,less rain and cold = less rust build up on discs,mine were grinding and crunching all winter till the sun came out last week now theyre so much quieter ,its like driving a completly different car .

Your brakes only make crunching/creaking noises when going over speed humps?
