Unless these Product Codes are for the identical Sachs front springs that match build code L58, then eurocarparts would appear to have made a mistake. Also, eurocarparts are showing that both Product Code: 62744130 and Product Code: 627790480 match build code L59. Unless these Product Codes are for the identical Sachs front springs that match build code L59, then eurocarparts would appear to have made another mistake. On eurocarparts, to see the listings of the Sachs springs that show the L58 and L59 build codes it appears that you have to select the Octavia MK2 2.0 diesel. eurocarparts product codes 627447560 and 627780520 are listed against both the Octavia MK2 2.0 petrol and Octavia MK2 2.0 diesel cars, whereas all the above four product codes are listed against the Octavia MK2 2.0 diesel cars. It appears that eurocarparts don't list Sachs 998411 that matches 1K0411105DA.

Sachs 998 412 matches 1K0411105EB which isn't listed as an Octavia MK2 VRS front spring. However, the specification of 1K0411105EB is similar to 1K0411105DB. Sachs 993 053 matches 1K0411105DB. On autodoc, Sachs list the 1K0411105DA for the petrol VRS with manual gearbox. On autodoc, Sachs list the 1K0411105DB for the diesel VRS with manual gearbox and petrol VRS with automatic gearbox. On autodoc, Sachs list the 1K0411105DC for the diesel VRS with automatic gearbox. However, it's always worth checking the car's build codes to find out what front springs the car actually left the factory with as this could be different from what Sachs or any other aftermarket spring brand recommends.

It sounds like the brakes are freeing up with a little use. Maybe just use the car normally for the next week or so and see if things continue to improve. The fact that your brakes are now at a much reduced temperature sounds very promising.

Not using the car regularly, ie. weeks or months, could cause the brake calipers to start to stick especially on an older car. The MOT checks for wheel bearing play, and would fail if significant wheel bearing play was felt. I doubt that is what is causing the smell and heat. Do the foot brake test with the engine running first and see how you get on. After you've done the footbrake test, you could also apply the handbrake and then release to see if that is causing the problem, ie. a sticking handbrake.

Many people buy secondhand cars and won't know if their car has a slightly different tyre size to what is approved. If your advice is taken to the logical conclusion then maybe half the cars on the road aren't insured due to a slight discrepancy. Fortunately, UK insurance companies are governed by the UK courts, and I think you will find that a modification that doesn't make a material difference to the risk can't be used as a get out clause by the insurance companies...or they would all be doing it. Even in the same size, tyres vary enormously in their performance. It wasn't long ago that UK insurance companies were expecting drivers to use summer tyres in the snow (even though that increases the risk of an accident) or if drivers used the most suitable winter tyres in the snow they faced an increase in their insurance premiums because the UK insurance industry unilaterally decided that using winter tyres in the winter was a modification. However, the UK courts soon put the UK insurance industry in their place when they found out about what they had been doing. It's about time a law was passed that banned insurance companies from interfering in drivers' choice of tyres because they simply don't have the expertise to make rational decisions on the subject, as was shown by the summer/winter tyres fiasco.

I suspect a sticking brake caliper and/or brake caliper piston, or a faulty flexible rubber brake hose. Sometimes a flexible rubber brake hose can swell internally, so that brake fluid can pass at high pressure such as when you operate the foot brake, but when you release the foot brake the brake fluid doesn't return easily due to the internal swelling...hence causing the brakes to stick. Jack the car up so that at least the wheel that gets hot is off the ground. Start the engine and aApply the footbrake firmly, then see if you can easily turn the wheel by hand. The engine is started because the brake are only power assisted with the engine running. If the wheel doesn't turn easily by hand, then you have a problem.

If you have a shock absorber that is "misting" I suggest you wait to see if it passes the MOT. If it fails, it's a leak.

That website is wrong because it doesn't know that you have 312mm diameter front brake discs. It shouldn't be showing the rim touching the brakes. 205/55R16 is a factory option on some Superb MK2 cars with 312mm front brakes. If you had a lower powered Superb MK2 with the smaller 288mm diameter front brakes discs, that website would still show the rim touching the brakes even though there would be loads of room. If you compare 225/45R17 with 205/55R16, that website shows that there's plenty of room between the brakes and rim. However, that website is worse than useless at showing whether the brakes will touch the rim because it is misleading. It's not actually designed to show whether the rim will clear the brakes as it doesn't have the data to come to a rational conclusion.

The Superb MK2 uses either 288mm, 312mm, or 340mm diameter front brake discs. 15" rims will fit over 288mm front brake discs. 16" rims will fit over 312mm front brake discs. 17" rims will fit over 340mm front brake discs. Only the 3.6FSI 256HP engine uses the 340mm front brake discs. 16" steel rims will easily fit over 312mm front brake discs, because steel is much stronger than cast aluminium so there will be more clearance when a 16" steel rim is used. Superb MK2 brakes https://www.lllparts.co.uk/catalogs/skoda/CZ/SUP/768/6 For further proof, you can look at the Audi TT 1st generation. The smallest front discs they used were 312mm, yet they often came out of the factory with 16" rims. On autodoc, Jurid shows that the Superb MK2 with 2.0TDI and 1.8TSI engines have 312mm front discs. wheel-size.com show that these cars had a 16" wheel factory option. You can see that the below cars had a 16" factory wheel option. Even the Superb MK3 can be fitted with 16" wheels, except for the 2.0TSI 272HP/280HP 4x4 versions that are fitted with the big 340mm front brakes. Skoda dealers even sell a 205/55R16 spare wheel for the Superb MK3 that fits all versions except the 340mm big brake cars. Bear in mind that the front brakes fitted to the Superb MK3 are never less than 312mm. Some versions of the Superb MK2 come with smaller 288mm front brakes, and 15" rims will clear their front brake calipers. 288mm front brakes are even marked as compatible with 15" rims in the "skoda parts catalogue" 288mm front discs are marked as compatible with 15" rims Floating caliper brake Brake caliper housing calliper carrier Brake disc (vented) front TEVES 288X25MM 15" https://www.lllparts.co.uk/catalogs/skoda/CZ/SUP/768/6/615/615025 Skoda Superb 2014 1.8TSI – Generation: II B6 (3T) [2008 .. 2017] – Power: 150 hp | 112 kW | 152 PS – Engine: 1.8L, CDAB, I4, Petrol – Center Bore: 57.1 mm – PCD: 5x112 Tire Rim 205/55R16 94V 7Jx16 ET45 2.3 / 2.1 225/45R17 94W 7.5Jx17 ET49 2.4 / 2.2 Skoda Superb 2014 1.8TSI – Generation: II B6 (3T) [2008 .. 2017] – Power: 158 hp | 118 kW | 160 PS – Engine: 1.8L, CDAA, I4, Petrol – Center Bore: 57.1 mm – PCD: 5x112 Tire Rim 205/55R16 94V 7Jx16 ET45 2.3 / 2.1 225/45ZR17 94W 7.5Jx17 ET49 2.4 / 2.2 Skoda Superb 2014 2.0TDI – Generation: II B6 (3T) [2008 .. 2017] – Power: 138 hp | 103 kW | 140 PS – Engine: 2.0L, I4, Diesel – Center Bore: 57.1 mm – PCD: 5x112 Tire Rim 205/55R16 94V 6Jx16 ET50 2.3 / 2.1 205/55R16 94V 7Jx16 ET45 2.3 / 2.1 https://www.wheel-size.com/size/skoda/superb/2014/ Audi TT 1st generation uses 312mm front brake discs 98N0615301A Brake disc (vented) 312X25MM 5/100 https://www.lllparts.co.uk/catalogs/audi/RDW/ATT/229/6/615/615025 Audi TT 1st generation uses 16" wheels 2 8N0601025C Aluminium rim 7 JX16H2 ET31 5/100 4 PR-C4M 8N0601025C Z17 Avus silver https://www.lllparts.co.uk/catalogs/audi/RDW/ATT/229/6/601/601050

I suggest you change your wheel size (tyres and rims). There's a good market on ebay for secondhand wheels, so you shouldn't have too much difficulty shifting your old wheels if they are in reasonably good condition. If you're looking at new tyres and rims, 16" will work out cheaper than 17" because steel rims are available in suitable 16" sizes, whereas suitable rims for the 225/45R17 tyre size will only be available in aluminium. 205/55R16 tyres will be cheaper than 225/45R17 tyres. 205/55R16 tyres will be noticeably more comfortable than 225/45R17 tyres. 205/55R16 are generally quieter than the wider 225/45R17 tyre size. 205/55R16 will reduce the fuel consumption a little, compared to the wider 225/45R17 tyre size due to less weight and reduced drag. So lots of benefits in going to the narrower 205/55R16 tyre size compared to 225/45R17. Michelin CrossClimate 2 205/55R16 https://www.blackcircles.com/tyres/205-55-16?seasonal=allseason&manufacturer=michelin&delivery=1&id=11377 Michelin CrossClimate 2 225/45R17 https://www.blackcircles.com/tyres/225-45-17?seasonal=AllSeason&manufacturer=michelin&delivery=1&id=11377 The above 16" Michelins are labelled at 69dB and the above 17" Michelins are labelled at 71dB. So the 16" Michelins are quieter than the wider 17" Michelins. You can see on mytyres that both 6Jx16 ET50 5/112 57.1 steel rims and 7Jx16 ET45 5/112 57.1 steel rims are available. The narrower 6J rims are a winter tyre size, but would be ideal for use with all-season tyres because they are officially winter rated due to their 3PMSF (3 Peak Mountain Snow Flake) symbol. This means that they have passed a test for good traction in the snow, which is why they are winter rated. The narrower 6J rim will also provide more comfort than the wider 7J rim. This is because the tyre sidewalls flex more easily when fitted to narrower rims. 16" steel rims https://www.mytyres.co.uk/rims/rim-selector?type=steel&vehicle_ids=182113210420171888%3A%3A0001 The main reason for going to 17" over 16" is the appearance. However, you can get some attractive wheel trims in the 16" size. The below is a VW wheel trim, but Skoda wheel trims are also available. https://www.amazon.de/-/en/Original-Pieces-Complete-Sportsvan-1T0071456A/dp/B01C22X3HK/ref=sr_1_3?crid=1N7LZK92TCZFN&keywords=vw+16+zoll+radkappen&qid=1663075781&sprefix=vw+16+%2Caps%2C81&sr=8-3 Skoda Octavia MK3 steel rims (6.5Jx16 ET46 and 6Jx16 ET48) https://www.mytyres.co.uk/rims/rim-selector?type=steel&vehicle_ids=185949956245308528%3A%3A0001 Skoda Octavia MK3 wheel trim for 6Jx16 ET48 steel rim https://eshop.skoda-auto.cz/cs_CZ/celoplosne-kryty-kol-nordic-16/p/5E0071456E Skoda Octavia MK3 alloy rims (6.5Jx16 ET46 and 6Jx16 ET48) https://eshop.skoda-auto.cz/cs_CZ/hlinikove-disky/c/alloyWheels?sort=priceAsc&q=%3AscoreDesc%3AcarType%3AOctavia%2BIII%2B%282017%2B%29&show=Page# I've included links to Octavia MK3 rims because they are a similar specification (but not identical) to Superb MK2 rims, ie. 6.5Jx16 ET46 and 6Jx16 ET48 for the Octavia MK3, and 7Jx16 ET45 and 6Jx16 ET50 for the Superb MK2. This opens up a lot more options. "skoda eshop cz", for example, are no longer listing any alloy rims for the Superb MK2 but are still showing plenty of Octavia MK3 alloy rims.

Many folks buy secondhand cars and won't be aware if their car has a non-standard tyre size. Ultimately, UK insurance is governed by UK courts. I suspect that any insurance company would have to show that the modification has made a material difference to the risk. This may explain why my insurance company once told me that they were happy for me to change my tyres by one size as long as it didn't increase the performance. Also, it's not uncommon for tyre fitters to fit the next nearest size if they don't have the correct size in stock, without even telling the customer. I would have thought that it's far worse for a driver to be driving around with faulty brakes, than have one size difference in their tyres. Also, even the same size tyres vary hugely in performance. You can fit the cheapest, worst performing Chinese remoulds on your car and apparently your car is still fully insured. It's strange how no one from the UK insurance industry clears up all this confusion. Although not long ago, they were encouraging drivers to drive in the snow on summer tyres...or they would increase their premiums if they fitted winter tyres.

If you mean size 215/50R18, they are widely available. However, the Karoq 4x4 uses the slightly bigger 225/50R18 size.

See this youtube video starting at 2 minutes 16 seconds, where the autodoc mechanic uses a wind back tool with an adaptor. It looks like he has taken my advice about being careful not to rotate the piston, because he has left the piston side brake pad in place while he pushes the piston back. thi

It does. Where is the discrepancy?

As long as you can do the job without damaging anything. Using a wind back tool on a brake caliper piston that is not designed to be rotated could damage the outer dust seal. Although an adaptor would be used with the wind back tool, unless the adaptor's bearings are incredibly smooth (not likely with cheap Chinese tools) this would create a twisting force on the brake caliper piston and rotate the piston possibly damaging or stressing the outer dust seal. A damaged brake caliper piston seal will let in water and cause the piston to seize, resulting in the need for an expensive brake caliper rebuild or replacement. Very common "piston wind back tool" set probably all made in the same Chinese factory

You can get a disc brake spreader tool on ebay/amazon. This is a very popular design which is sold under various brand names and also unbranded. They are probably all made in the same factory in China and are available from just over £8 including postage. The tool enables you to push the front brake caliper piston back before removing the old front brake pads. https://www.ebay.co.uk/sch/i.html?_from=R40&_nkw=disc+brake+spreader+tool&_sacat=0&_sop=15&rt=nc&LH_ItemCondition=3

In the 2022 auto bild summer tyre test, the Turanza T005 could only do 62.25% of the mileage of the winning Goodyear EfficientGrip Performance 2. I doubt the T006 will be much better if any in that regard. 2022 auto bild summer tyre test https://www.tyrereviews.com/Article/2022-Auto-Bild-Summer-Tyre-Test.htm

If your top gear was currently pulling 29mph/1,000rpm, then a 3.5% increase in gearing would mean that your top gear was now pulling 30mph/1,000rpm, ie. a 3.5% increase in gearing. Of course this increase in gearing applies to all the gears.

The 17" rims also come in the narrower 7J width. Fitted with a 225/45R17 tyre, you would get a more comfortable ride and better rim protection from kerbing damage.

Maybe you could weigh one to check this. If you are going to change the tyres, perhaps weigh the wheel (rim and tyre) before the change. Then when the old tyre has been removed from the rim, weigh that and deduct that weight from the weight of the complete wheel before the old tyre was removed. The below alloy rim weighs about 7.3kg, ie. half the weight of the above rim. The reason that it's so light is because it's made from forged aluminium, whereas most car alloy rims are made from much heavier sand cast aluminium. 7Jx16 ET45 5/112 forged alloy rim (from Audi A4/A6 cars around the year 2000) 9 8D0601025K Aluminium rim 7Jx16 ET45 5/112 8D0601025K Z17 Avus silver https://www.lllparts.co.uk/catalogs/audi/RDW/A4/223/6/601/601060

Compared to 205/55R16, 225/45R18 will raise the gearing by 4.4%. Compared to 225/45R17, 225/45R18 will raise the gearing by 4.0%. Compared to 225/40R18, 225/45R18 will raise the gearing by 3.5%. If you look at the below chart, 205/55R16 is the best value and 69dB is quiet. However, out of 225/45R17 and 225/45R18, the 17" tyre is the better value and keeps the gearing standard.

The shims are there to reduce brake noise. Many aftermarket brake pads don't include them because they are not noisy even without the shims. If your brakes aren't noisy without them, then you don't need them.

If you do try 3Q0511115M rear springs, I suggest you measure the wire diameter before fitting. I've seen these 3Q0511115M springs listed on autodoc with three different thicknesses, 12.5mm, 12.75mm, and 13.0mm. Most were listed at 12.75mm. If they have a wire diameter of only 12.5mm it might be better to return them to the seller for a full refund and not fit them, as I wouldn't expect them to be stiffer than 3Q0511115AL just longer...perhaps around 6mm longer. So your rear end might be raised 6mm but the stiffness might be the same as the 3Q0511115AL springs. Unfortunately, Kilen and Lesjofors don't list the specification of their springs. The Eibach R21093 is the only 3Q0511115M rear spring listed with a claimed wire diameter of 13.0mm, so that one might be worth trying as it should be the stiffest 3Q0511115M spring if the claimed 13.0mm wire diameter is true. 3Q0511115M https://www.autodoc.co.uk/car-parts/oem/3q0511115m?search=OEN 3Q0511115M
