Skoda Centre Caps 5E0601151 FOD (206.99CZK is about £7.10) https://eshop.skoda-auto.cz/cs_CZ/ozdobny-stred-kola-/p/5E0601151++FOD You should be able to order from a Skoda dealer using the above OEM part number.

As you can see in the autodoc link below, there are two types. 440N and 460N for the Octavia MK2 hatchback. The 460N is when you have a rear wiper as it add a little weight to the tailgate and therefore needs a little extra force. Stabilus are OEM quality. The "N" in 440N and 460N means Newtons, which is a measurement of force. 1kg is about 10N, so these give about 44kg and 46kg of force respectively. They both have a length of 584mm, and a stroke of 240mm. Using struts from the wrong car, is likely to give you the wrong force, the wrong length, and the wrong stroke. If you make a note of the part number, you can probably find them on ebay and amazon, etc. You can see how easy they are to fit by watching a video on youtube. Or just examine the new ones carefully, to understand what you have to do to get them to clip on and off.

As you can see in the charts and links below, the Audi TT had different 6Jx16 ET31 and 7Jx16 ET31 alloy rims depending on whether it was an earlier 1999-2002 car or a later 2003-2006 car. The earlier 6J rims were a 12-spoke design, and the earlier 7J design were a 5-spoke design. Both the later 6J and 7J rims were a 7-spoke design. The narrower 6Jx16 ET31 rims were for winter tyres and would have been suitable for use with snow chains on the Audi TT.

For the Roomster, I would go with 185/65R14 fitted to either 5Jx14 ET35 or 6Jx14 ET37 steel rims. mytyres are listing both of these standard rim sizes, and the 6Jx15 ET43 size. 175/70R14 and 185/65R14 are both standard tyre sizes on the Roomster. 185/65R14 gives better grip than 175/70R14. 195/55R15 could be used on the 6Jx15 ET43 rim, but the ride would be noticeably harder than the 14" tyres, and it's a more expensive size. 5Jx14 ET35, 6Jx14 ET37, 6Jx15 ET43 Steel Rims listed on mytyres https://www.mytyres.co.uk/rims/rim-selector?type=steel&vehicle_ids=183698156431610980%3A%3Aundefined Vredestein Quatrac 5 185/65R14 86T All-Season Tyres with the 3PMSF symbol https://www.camskill.co.uk/m137b0s7980p144832/Vredestein_Tyres_All_Season_Car_Vredestein_Quatrac5_Vredestein_Quatrac_5_-_185_65_R14_86T_TL_Fuel_Eff_%3A_E_Wet_Grip%3A_C_NoiseClass%3A_1_Noise%3A_68dB

This should help you with the physical size. https://www.yuasa.co.uk/batteries/automotive/ybx9000-agm-batteries.html If it's around 60Ah, it's probably this size. Length 242mm Width 175mm Height 190mm The link is for AGM batteries which aren't suitable for cars that are not stop-start, but the physical size of those L1 to L6 batteries should help you identify what size you have.

The rim width and offset partly depends on the tyre size. Narrower tyre tends to have less offset. Wider tyre tends to have more offset. Take a look at wheel-size.com to see what rim widths and offsets the Fabia MK2 uses as standard. https://www.wheel-size.com/size/skoda/fabia/2010/ wheel-size.com does often make mistakes, but you should get the general idea. Also, take a look at these 15" Audi A1 rims. You can see rims with 6Jx15 ET29 and 6.5Jx15 ET34 specifications. https://audi.7zap.com/en/rdw/audi+a1/a1/2014-708/6/601-601050/ 185/55R15 fitted to 6Jx15 ET29 or 195/50R15 fitted to 6.5Jx15 ET34 might be a good starting point for that flush with the outside of the wheel arch look. 6Jx15 ET29 steel rims on mytyres https://www.mytyres.co.uk/rims/rim-selector?type=steel&vehicle_ids=46711651994440804

What is the date code on the tyres? Rubber hardens and cracks with age. It's not a good idea to use winter tyres that are more than 7 years old, so always check the date code on tyres before purchase. As you can see from the chart below, these 7Jx16 ET42 5/112 alloy rims have OEM part number 8E0601025F Z17 and were originally fitted to cars such as the Audi A4. The Z17 colour code means that they were avus silver before someone painted them black. The Octavia MK3 Scout 4x4 usually comes with 225/50R17 tyres fitted to 7Jx17 ET45 5/112 rims. The Scout isn't usually fitted with 16" wheels. The outside diameter of 205/55R16 tyres is too small for the Scout. The standard 225/50R17 tyre size has about a 3.9% bigger outside diameter than 205/55R16.

This is the 278mm long model. The sizes either side have a length of 242mm and 317mm, ie. 36mm shorter and 39mm longer...so you don't have to measure your current one exactly to find the same size.

My AGM has always undercharged in a conventional charging system. 12.1V is the maximum it has ever charged to.

I have used an AGM in an older car than yours. After 2 years, it's still working well. However, next time I would probably buy a regular SLA battery as they usually last me over 10 years and are quite a bit cheaper. I suggest you only purchase a top brand of battery such as Varta. Is that the correct physical size for your car that you have linked to? Length 278mm Width 175mm Height 190mm

There's many inaccuracies in your post. I usually refer to the 245/45R18 as slightly oversize, never as a standard fitment because its not. I haven't suggested anyone fit standard load index 235/40R19 tyres. I have used the standard load index in all tyre sizes to assess comfort levels and tyre pressures, as this creates a level playing field for the comparisons. Comparing a 245/45R18 96 SL (Standard Load) index tyre with a 235/40R19 96 XL (eXtra Load) index tyre would be meaningless, because the standard load index tyre gets its load index from 44psi (3Bar), whereas the XL index tyre gets its load index from 51psi (3.5Bar). 235/40R19 with a standard load index aren't necessarily cheap. For example, by far the cheapest tyre in that size currently listed on mytyres is an XL tyre. However, I've never encouraged the use of cheap, poor performing tyres as it's a very bad idea. In fact, I'm a big fan of top performing all-season tyres with the 3PMSF symbol that work well in all conditions. From a point of safety, a 235/40R19 standard load index tyre can support the same weight as an XL tyre in the same size when they are inflated to the same pressure up to 44psi (3Bar), eg. both tyres can support the same 630kg weight when inflated to 44psi (3Bar). The XL index tyre can only support more weight than the SL index tyre when inflated above 44psi (3Bar).

It's not incorrect. I gave the standard load index, not the XL (eXtra Load) index. I used it to compare the comfort levels and assess the tyre pressures between different tyre sizes. You can't compare comfort levels and tyre pressures from one size to another, if you use the standard load index on one tyre size and the XL index on the other tyre size. Going by the tyre label inside the fuel filler flap, the Superb MK3 fitted with slightly oversize 245/45R18 tyres would need 32psi (2.2Bar) front and 32psi (2.2Bar) rear with a lightly loaded car, and 35psi (2.4Bar) front and 39psi (2.7Bar) rear with a heavily loaded car. These figures are obtained by comparing the recommended tyre pressures and standard load indexes (not XL) of the 235/40R19 tyre size and the slightly oversize 245/45R18 tyre size. The 235/40R19 tyre size can support 630kg when inflated to 3Bar, and the slightly oversize 245/45R18 tyre size can support 710kg when inflated to 3Bar. Bear in mind, that the weight a tyre can support is proportional to the tyre pressure. For example, halve the tyre pressure and the weight it can support is halved...and vice-versa...double the tyre pressure and the weight it can support is doubled. You can't inflate a tyre to more than it's recommended tyre pressure, and you can't support more weight than recommended by the tyre manufacturer.

I've corrected the 2nd sentence below. I meant the only 16" rim size approved by Skoda for the Yeti is 7Jx16 ET45. I've also added a 3rd sentence so that the Superb MK3 is included, as that also uses a 215/60R16 tyre size. Notice that all three vehicles are using different rim widths and offsets even though they are all using the same 215/60R16 tyre size. You wouldn't necessarily expect all three vehicles to use the same offset, but it's surprising that they are all using different rim widths for the same tyre size. The only 16" rim size approved by Skoda for the Karoq is 6Jx16 ET43. The only 16" rim size approved by Skoda for the Yeti is 7Jx16 ET45. The only 16" rim size approved by Skoda for the Superb MK3 is 6.5Jx16 ET41.

The only 16" rim size approved by Skoda for the Karoq is 6Jx16 ET43. The only 16" rim size approved by Skoda for the Karoq is 7Jx16 ET45. It sounds like you have been driving around on rims with a different width and/or offset to the approved sizes. The ride quality on 215/60R16 tyres fitted to relatively narrow 6J rims should be much better than 215/55R17 tyres fitted to relatively wide 7J rims. Relative rim width has a significant effect on ride quality, because the sidewalls of a tyre fitted to a relatively narrower rim flex more easily.

What are the official tyre pressures with the 235/40R19 and 235/45R18 tyre sizes, and are you using them? You might find the official tyre pressures on a label inside the fuel filler flap. Standard load index (ie. not XL) 215/60R16 95 215/55R17 94 235/45R18 94 235/40R19 92 245/45R18 96 Notice that the standard load index on 245/45R18 is 4 higher than 235/40R19. This means that you can use about 4psi lower tyre pressures on the 245/45R18 size compared to 235/40R19. Running underinflated 19" tyres in a desperate attempt to match the comfort of slightly over-sized 18" tyres is not the answer, as the rims could be far more easily damaged by potholes, and under-inflation has an adverse effect on handling. Plus it's illegal to run under-inflated tyres and dangerous. Severely under-inflated tyres can lead to a blow-out due to overheating at high speed.

Most all-season tyres have the 3PMSF (3 Peak Mountain Snow Flake) symbol marked on their sidewalls. Having the 3PMSF symbol is the technical definition of a winter tyre. In the photo below, you can see the 3PMSF symbol. It's the triangle shaped symbol, with the 3 peaks. Winter Tyres 3PMSF https://en.wikipedia.org/wiki/Snow_tire

Low profile tyre weren't invented until 1968 when Dunlop brought out the 70 series tyre, and the Jaguar E-Type had their 185/80R15 tyres upgraded to 205/70R15. The basic 16" Karoq tyre size is 215/60R16, and this is an upgrade to the 205/70R15 tyre size, as 205/70R15 and 215/60R16 have the same outside diameter and are interchangeable. Therefore, I'm not surprised Ken is finding his "basic" 16" Karoq tyres rather good...they certainly aren't low performance. The Jaguar E-Type would have loved them. https://en.wikipedia.org/wiki/Jaguar_E-Type#/media/File:Jaguar_E-Type_series_1_coupé_1964.jpg

Changing from 235/40R19 on 8J rims to 245/45R18 on 8J rims would make a noticeable improvement to ride comfort, especially if you drop the tyre pressures by 3psi-4psi. You can drop the tyre pressures because 245/45R18 has a higher load index than 235/40R19, so doesn't need as much pressure to support the same weight. Notice on the below links that the 18" tyre is £165.25 cheaper for 5 tyres than the 19" tyre, and has less rolling resistance.

5mm difference in spring length is insignificant, bearing in mind that the same springs with the same OEM part numbers could vary by 10mm in length even if ordered from a Skoda dealer. Different batch, different factory, etc. Also, the actual ride height will vary enormously depending on the load you are carrying...there will be much more than a 5mm difference in rear ride height between a lightly loaded car and a heavily loaded car. For example, a car with just 1 or 2 front passenger may have the rear axle supporting 600kg...but a car with 2 or 3 rear passengers, all of their luggage, and maybe a caravan in tow could have the rear axle supporting 900kg...ie. a 50% increase. This is a big difference for the rear springs to cope with. The rear springs in a lightly loaded car could feel too hard, but when the car is fully loaded the same rear springs could feel too soft...such is the compromise of choosing suitable rear springs.

Eurocarparts are selling 4 valve cores for £1.09 https://www.eurocarparts.com/p/valve-cores-short-BAR321 Halfords are selling 4 valve cores for £5 https://www.halfords.com/tools/garage-equipment/breakdown-essentials/halfords-valve-cores-171862.html A pack of 5 valve cores might be better, as some owners still have a spare wheel and might want to change all 5 valves cores on their car. However, I can't remember ever having to change one, although I always use valve caps (like you're suppose to) which keeps the dirt out of the valves.

If spit just formed a film, without an air bubble forming...then there's no air escaping...and therefore the valve is working. If air is escaping, then you need to change the valve core. This is the kind of tool that you need to change the valve core. There's no need to overtighten the valve core, so don't use too much force. https://www.ebay.co.uk/itm/184589472431?epid=1805249469&hash=item2afa63d2af:i:184589472431 10 valve cores (99p including postage) https://www.ebay.co.uk/itm/160958141509?hash=item2579da5445:g:GRoAAMXQUY1Q~tNd

Pump the tyre up and see if air is leaking out of the valve. You can put a bit of soapy water on the end of the valve to check for air bubbles, if you can't hear or feel air coming out of the valve. It's the valve core that is designed to stop the air leaking, not the valve cap. The valve cap's job is to stop dirt getting into the valve core, although the valve cap does provide a secondary seal.

Below 0 degrees Centrigrade, the Kleber Quadraxer 2 outperforms most all-season tyres. Handling in the snow is better than the CrossClimate 2. At under £130 including shipping, it's a lot less than the Michelin. Kleber is a Michelin brand, and should give similar high mileage. Think of the Quadraxer 2 as a winter tyre, that can also be used in the summer...ie, a winterised all-season tyre, so like the Nokian all-season tyres that are also winter focused. 245/45R18 is a good alternative to the standard 235/45R18 tyre size on the Superb MK3's 8J rims. The sidewalls on 245/45R18 will bulge out a little more than the 235/45R18 size, thereby giving a little more rim protection from kerbing damage. The ride should be slightly improved too. 245/45R18 is a more common and cheaper size than 235/45R18.
