Hi All,

 

I'm hoping someone can help, or at least put my mind at ease. I've decided to replace the rear coil springs on my 2008 Superb hatchback. I don't think they've ever been replaced, and I'm up to 310,000km at this stage, so they probably need doing at this point. I might replace the shock absorbers as well, but I haven't made my mind up on that yet. The front springs I think I'll let a garage replace at some point - had a look at videos and read the procedure on here and really think it sounds like something that could do horribly wrong in my hands!

 

Anyways, I jacked the car up, took off the wheel and had a look at the colour code on the existing springs. 3 paint marks: 1 white, 2 orange (well, more brown to me but the parts table don't list that combination as an option, so I'm sticking with orange! I've added a pic in case anyone wants to debate brown versus orange...). According to this site, that equates to part number 1K0511115BH. I also checked it on this site, and that says the same thing (using the same database I think). So I search for 1K0511115BH on various websites looking for the cheapest price etc. So far so good. I get lots of results back: Sachs, BE, Febi etc. Marvellous. Here's the problem: different suppliers seem to think the springs are completely different dimensions! For example, Sachs think the springs are 364mm in length, 12mm thick. Febi think the springs are 355mm long and 12.5mm thick. Most of the manufacturers seem to fall into one of those two sizing camps.

 

So I'm confused! Is it just a case of duff information being supplied by the manufacturers (the dimensions seem to be consistent across different websites by manufacturer), or are they actually supplying different length springs and I should measure what I have before ordering anything? I really don't want to have to go to the hassle of removing one of the springs to measure it before ordering. Plus, if they have compressed over the years, how would I even know what the orginal length was?

 

Basically what I'm asking is: should I just go ahead and order my chosen brand based on the colour code and PR code that I've found, or what should I do? I was leaning towards Sachs for no real reason other than I recognise the name and they've not extortionate (about €38 per spring). But by the same token I was also considering Febi. Does anyone have a recommendation? I'm trying to order from a stockist in Ireland or the EU, rather than the UK because I want to avoid Brexit-related postal delays if at all possible!

 

Thanks in advance for all replies. And a happy new year to one and all.

Do you have a Vernier caliper or micrometer to measure the thickness of the rear springs on the car?

 

What Sachs part number are you looking at? 

 

According to the 7zap site, 994329 should be the equivalent Sachs part:

 

@Carlston is the man when it comes to spring dimensions and equivalents though.

 

I've feck all in the way of measuring tools.

 

Yep, 994329 is the Sachs number I'm looking at. Like I say, I just find it disconcerting that other manufacturers have different measurements all using the same product code.

The first thing to do is make sure you know the OEM part number of the rear springs that you have on the car.

 

You have a 2008 Superb MK2 hatchback. But what engine? Automatic or manual gearbox? Is it a greenline model (which would usually mean 15mm lowered springs)? Did it have a factory fitted towbar (which would usually mean stiffer rear springs)? Is it 2WD or 4WD?

 

Edited 29 December, 20205 yr by Carlston

The paint marks as shown in the photo would be enough to ID the OEM spring as the part number number the OP quotes, I think?

 

 

Another thing to think about is that if the springs are both intact, and not unduly rusty at any point, they are probably actually fine.  Rears don't tend to fail anything like as often as fronts, in my experience.

 

We don't know what the coloured dots are. We are guessing. Is the first dot white or silver? Are the 2nd and 3rd dots the same colour?

 

1 white 2 orange 1K0511115BH which has build code PR-0YD

 

1 white 2 green 1K0511115BL which has build code PR-0YK

 

According to gknautomotive's online catalogue it looks like it is 1K0511115BH for most engine variants.

 

Specification of 1K0511115BH according to gknautomotive

 

Spring Design	Coil spring with constant wire diameter
Fitting Position	Rear Axle
Thickness	12,00 mm
Length	364 mm
Outer diameter	117 mm
Weight	2,10 kg

 

Optimal, Sachs, Spidan, Suplex, and TRW, are all giving similar specifications for this OEM number.

 

You could also consider Kilen who also appear to do an exact replacement for this OEM number.

 

Edited 29 December, 20205 yr by Carlston

The 0YD PR code might appear on the boot-floor build data sticker, with a bit of luck.   @Declan O'Shaughnessy could you have a look?

I'm pretty happy that I have the correct PR code. There's only three paint marks. Silver isn't listed as a "colour way" on the websites I used to find the PR number, so I'm happy that the first colour is white. I'm also happy that the next two colours are the same. My only (slightly tongue-in-cheek) comment was that the colour could as easily be orange as brown. But given that none of the colour codes list brown as appearing more than once, and none list brown and orange both appearing once in a three-colour variation, I am happy to go with the colour code and PR code that I originally listed.

 

My original question was why a single PR code would be associated with springs of differing dimensions (according to the listed measurements). My best guess is that it's duff information loaded onto a central server that all the other websites use. I might be wrong on that, but I can't see what else would be the case.

@Wino That's interesting, thanks. I was under the impression, from reading posts on here, that it was a miracle that I had any spring left on my car at all. I looked at both springs earlier and couldn't see any rusting at all, they looked in remarkably good nick. But, having used the information supplied by @chimaera on one of his posts, my back end definitely seems to be sagging a little from the official specs.

@Carlston Thanks for that, it's helpful. I'm happy that I have 1K0511115BH  on the car, and those specs match those listed by Sachs, so I'm happier now that the Sachs would safe to buy.

 

Thanks for the help guys. If I go ahead with the job, I have a couple of questions about the procedure, but I'll save those for another day (the wife wants to watch Harry Potter now, which means I will be watching Harry Potter now!).

I think you might end up replacing springs unnecessarily, but if you hang onto the old ones, at least you'll have spares in case of breakage of new ones.

 

The answer to why some manufacturers (or re-branders) may quote different dimensions is that they probably rationalise the many, many slightly different OE springs down to a subset of a few "that'll do".

 

Just to point out PR code is not the same as part number, you seem to be using them interchangeably.

Part number is the 1K0511115BH. 

PR codes are three characters, usually a mix of numerals and letters, such as the 0YD that specifies one aspect of the rear suspension. A number of these PR codes appear on the build data sticker in the boot. A full set can be had by asking a co-operative dealership parts person for the full 'car data' from the VIN.

 

 

Edited 29 December, 20205 yr by Wino

I summarised as much information on the rear suspension setup on these cars as I could find in the post linked below: 1x White 2x Orange is the part number you found (1K0 511 115 BH) for PR 0YD which is weight range 4 (very low). I would suggest in the first instance if your suspension is sagging that you replace the dampers. These have a sealed gas capsule in them that adds some spring stiffness and ride height. Eventually the capsule leaks and the dampers sag which makes the car sag. Your car is probably the standard chassis which is PR 1JA for damping meaning the p/n for your dampers is 1K0 513 029 JE. You'll need to replace the bolts securing the top of the damper to the body, and the wishbone pinch bolt at the bottom (I can't recall p/ns offhand for these but a dealer can get them easily for you).

 

I found even with new springs and dampers on my car, it was still sagging a little, as it's only weight range 6 and carrying a towbar. I added a set of MAD helper springs as suggested by @3T51704x4 in one of their threads on suspension. They have restored the rear to its correct ride height.

 

sorry to hitch a ride on this topic but I own a Superb mk2 combi (not in Europe) that came with aftermarket B12 kit.

 

Being a family wagon, we found it too low with a full load luggage and kids and would like to revert back to original springs and shocks.. maybe shocks I would go for the B6 kit for better handling.

 

Is there anyway to check the springs specs from the VIN no?

 

Thanks in advance..

There is a box to search by the VIN number on this website. I don't know if it works.

The following front and rear Bilstein B6 shock absorbers appear to fit any Skoda Superb MK2 with standard or sports suspension. It's a one size fits all approach.

Thanks for the replies. Will this website also work for VIN codes outside Europe?

 

I am getting errors from both sites when I enter my car's VIN.

 

Thanks

There are two suspension setups on the Superb 2, standard and sport. I've just replaced the rear dampers on my S2, I had to decode my options list to see what setup I have. I then had to cross reference my code (G50) with the Sach website to see if it's standard or sport (standard). From what I could work out virtually everything is standard with just the occasional G07 sport setup. 

There are also two rough road setups with higher ground clearance.

The build code G50 relates to the front shock absorbers as shown below, ie. build code G50 means that the front shock absorbers have OEM part number 3C0413031BD. It doesn't tell you (by reference to the Skoda online parts catalogue) what the front and rear springs are, or what the rear shock absorbers are. Other build codes are needed to work out those details.

Your absolutely right, I had G50 stuck in my head because I was considering biting the bullet and doing all 4 shocks. For some reason I remembered the front code.

Hi, 

 

Following up from my earlier post.

 

I own a skoda superb Mk2 2.0TSI. It came used with a set of B12 suspension kit.

I have several options I would like to explore to keep the height and handling workable as the B12 is too low once the family and luggage goes in....

 

1. revert back to original springs and shocks.

2.  b6 shocks with original springs.

3. b6 shocks with original spec "sports springs"... drop of abt 15 to 20mm.

 

Firstly can I get help to decode the original part numbers for my car for the front and rear shocks/springs.

 

Also can i use the sport spring parts to catch the B6 dampers. 

 

Thanks in advance guys...

Annoyingly, the build label on the Superbs only ever lists the front suspension PR codes, never the rear. On top of that, the description for the front PR codes is the same for all the variations (I've checked). As @Wino says, you'll need to get the rear PR codes either from a dealer, or by signing up to erWin (https://erwin.skoda-auto.cz/erwin/showHome.do). An hour's sub is cheap - what you're looking for is the 'Vehicle Specific Information'. You can download service manuals here too, the 24 h subscription might be better for this.

 

This list will provide you with the original specification for the rear suspension and then you can decide what to do with your car. The weight range will be the most useful PR code (it'll start with 0Y). The G07 code tells us you're on the standard chassis, rather than sport or one of the two rough-road options. The PR code for this option is 1JA. One of my earlier posts in this thread links to a thread where I've summarised the various rear suspension options in a matrix. Once you know what the weight range originally specified for your car is, we can see what might work for you. Anything else at this point would be guesswork.

Thanks all for the insight and info..

 

My local skoda dealer refused to provide me with part numbers stating Company policy... I guess. if do not buy from them then then they will not help. 

 

I will try a 24 subscription and see what I can pull out.

 

But am keen to see what the sports springs can match with the std dampers.

 

Cheers all...

Has your local Skoda dealer given you a price on standard shock absorbers, as that might be the way to go?

 

The problem with most aftermarket shock absorbers is that there's usually a one size fits all approach.

 

For example, Bilstein B4 22-151056 aren't just sold to replace 3C0413031AT but all of the following OEM part numbers (there are others).
