My 2012 Octavia II FL Estate 2.0TDI 140BHP has just failed its MOT on a broken offside rear spring. The garage wants £280 inc vat to replace both rear springs with genuine spare parts. Each spring is quoted at £74 + vat. I know that I am perfecty capable of doing the job as I do my own servicing and repairs and I fitted MAD assister springs to the rear of the car soon after I had bought it. The problem that I am having is trying to buy new springs that are the same length and spring rate as the original ones. I have tried the usual sites of Euro Car Parts, GSF, Ebay etc. but after I enter my registration number I am offered a selection of springs at various price by the same manufacturer. Some are marked "heavy duty" others are "without sports suspension" and some are just not specified. Other than going to the main dealer, and paying an arm and a leg, or finding a TPS branch, my local would be Stockport, that will serve members of the public these days is there any way of deciding which aftermarket spring is a direct replacement for the ones currently on my car. The sticker in the boot has a "L13 - Suspension Range 13 installation control only, no equirement forcast" whatever that means. I do not want to raise of lower the car or alter the ride I just want like for like!

I got the parts numbers from 7zap.com although I wanted uprated, if you already have the helper springs then you definitely want to find standard ones.

 

Mine were Lesjofors & cost €24 each delivered, probably the simplest job ever to do on the vehicle as you will already know from having fitted the helper springs.

There are loads of slightly different springs. Take a closer look and you should find some paint marks on the spring, they should match with the parts catalogue to give an exact part number.

 

This page will probably help for a 2012 estate with standard suspension: https://www.ilcats.ru/skoda/?function=getParts&market=CZ&model=OCT&modelcode=663&year=2012&group=5&subgroup=511&part=511001&pid=3181&language=en

Thanks to you both for the info. I will try to find some paint marks tomorrow.

 

However I have just looked on the www.onlinecarparts.co.uk website for one of the 10 springs listed in @langers2k post. On this webpage https://www.onlinecarparts.co.uk/oenumber/1k0511115bm.html I find that the stated lengths vary from 329mm to 370mm long! It should not be this difficult to buy a new spring.

You'll probably find that aftermarket spring producers just make one or two springs rather than the full range Skoda has 😕

 

i can recommend Kilen springs as I replaced a front spring and they were spot on, 

 

just check out the springs part number you need on their website and then source on ebay

Here's one I made earlier (I don't know why it's not a sticky to assist everyone)

 

 

Check the vehicle options via the VIN decoder.  Using the graphical diagrams, search and cross reference the part number(s) to be sure and then search that part number online on any sales site such as the bay sorted by lowest price.

 

Double check and cross reference before purchase.

The rear springs are slightly stiffer when a factory fitted towbar is fitted.

 

The OEM part number for the front spring is:

Sometimes I prefer Spidan or Suplex to Sachs. It often depends what matches up well to the original spring OEM part numbers. Spidan and Suplex appear to be covering the front spring on the Skoda Octavia MK2 Estate 2.0 TDI with a slightly harder front spring than standard with OEM part number 1K0411105BD. If you want slightly harder front springs then Spidan and Suplex are also options.

 

The difference in stiffness between the two rear springs is quite small, as it looks like the towbar spring has about half-a-turn less. Maybe 6-and-a-half coil spring turns instead of 7 coil spring turns. Maybe between 5% and 10% difference, but probably nearer to only 5% difference. One indication to the spring stiffnesses being fairly close, is in the OEM part numbers. The car without the towbar ends in F, and the car with the towbar ends in G, ie. only one alphanumeric number difference. Apart from the number of coil spring turns, the specification of the two rear springs is almost identical.

 

Spidan, Suplex, Sachs, Optimal, TRW are all good quality German made springs. Spidan, TRW, and Optimal aren't often sold in the UK market or are expensive, leaving Sachs or Suplex. Spidan springs are often sold on ebay.de but the postage to the UK is usually expensive.

I have checked on the car and both sides have the colours White-Yellow-Yellow which according to the webpage in @langers2k post is part number 1K0511115BE. This relates to a Kilen part number of 63117 and I have ordered a pair of springs of Ebay. I have also ordered new bolts and nuts from Skoda for the stretch bolt that I will have to remove. Thanks to all for your help and here is a photo of where the spring has broken.

Good choice with the Kilen 63117 spring.

 

White-Yellow-Yellow does appear to be 1K0511115BE. This is the OEM part number for the Hatchback not the Estate.

 

However, the Kilen 63117 uses a one size fits all approach as it replaces both the 1K0511115BE and 1K0511115BF OEM part numbers. This means that the Kilen 63117 will probably match the stiffer spring of these two OEM part numbers which is OEM part number 1K0511115BF. This is quite handy, as 1K0511115BF is the stiffer version for the Estate and not the softer version for the Hatchback.

 

It looks like Kilen 23110 would be the front spring as it matches OEM part number 1K0411105BC

If the Kilen 63117 is a stiffer spring than the one originally fitted do you think that I would still need the MAD auxiliary springs or will the ride be too hard when empty?  I do not tow a caravan anymore, we have sold it, but I do sometimes fit a Bosal towbar mounted bike rack with two bikes and a bootful of luggage for holidays in France although there is normally only 2 of use in the car these days.

I've found stiffer rear springs that will fit the estate. OEM part number 1K0511115BH. This is used on some Skoda Octavia MK2 hatchbacks and some VW Golf MK5 hatchbacks with factory fitted towbars. I would rather have these, than auxiliary springs.

 

OEM part number: 1K0511115BH

Specification: Thickness 12.00mm, Length 364mm, Outer diameter 117mm, Weight 2.10kg

Kilen 63131

 

https://www.ebay.co.uk/itm/2-x-NEW-KILEN-REAR-AXLE-COIL-SPRING-PAIR-SET-SPRINGS-GENUINE-OE-QUALITY-63131/254293095078?hash=item3b350cb2a6:g:h7cAAOSw3YtdJv2c

 

Compare that to the standard estate rear springs

OEM part number: 1K0511115BF

Specification: Thickness 11.75mm, Length 354mm, Outer diameter 113mm, Weight 1.95kg

Kilen 63117

 

As you can see, the heavier duty rear spring has a 0.25mm increase in thickness, a 10mm increase in length, and a 0.15kg increase in weight.
