Morning peeps,,

wondered if anyone could help regarding type of brake fluid I’d need or can use in my 2010 vRS 2.0 ltrive had a look on halfrauds and euro poop parts and they all say DOT4 ESP brake and clutch ??? 

can I not just a DOT4 or does it have to be ESP assuming that’s electronic stability program 

Any recommendations on what brand or stick with genuine skoda 

thanks peeps

That's correct, but ESP has no effect on which type of brake fluid you need.

Just pay the bit extra for the lower viscosity Dot 4 ESP.

It is there for cars with ESP, and for lower temperature places, so that is hardly relevant here. 

I've always used good quality Dot 5.1

Can I mix it with DOT 4 ,, it’s literally to do a fluid flush so it would be flushed out or at least a major majority of it 🤣,,

looked at mine at the weekend and it’s practically black 🤣

5.1 does mix, (5.0 can't just to confuse things)

This is an interesting doc I found on the web that mentions Dot 4 ESP, that does seem different with esp use at lower temperatures. I never even knew about it before looking up on your post.

I believe the correct fluid to be the LV Low Viscosity ESP type  VW 501.14

However I'm certainly not worried about the fact I used Dot 5.1. I live in London and that's not subject to extremely low temperatures. Maybe next time I'll use the LV type. The Comma Dot 5.1 I used is speced at 850 cST at -40°C, not much higher than the 700 cST of their DOT 4 ESP and as said London's doesn't get that cold.

 

Forget genuine Skoda or VW, they're just labels.  If you've got a VRS and you drive it then why not stick with the asked for ESP Brake Fluid DOT 4 but you don't have to if you don't want to, particularly if you're taking your car on a track or towing something heavy down many steep roads, then perhaps DoT 5.1.  If you want a recommendation of brand I like this (local-ish to you) British oil blending company and you can sometimes see their products on special offer prices at some suppliers (particularly when like other companies they change the labels on their bottles and cans to draw attention).  You are ahead of many by actually changing the brake fluid.

 

They're in Brighouse, West Yorkshire HD6 3DP.

 

Other brands are available.

DoT 5.0 (silicone) - not used in these cars

You would not use 5.0 (silicone) in these cars but having had various over-priced and over-valued old cars called "classic" as daily drivers for 30+ years I've seen and heard a lot about what you can and can't and must do with 5.0 (silicone) in the cars that can use it and have read about "classic" owners that have used it for years and decades.  One that discovered there was a mix of 5.0 silicone and DoT 3 or 4  in his when he drained the system.  A mate who's had it it in his classics, Sunday "classic" for 25+ years and other two 'dailies' and doesn't drive any of them like the standard old-fart "classic" owners, so decades of real life experience with it.

So I can say there's a lot of twaddle about on 5.0 silicone, including  from some brake manufacturers, refurbishers and non-5.0 silicone makers and sellers.  But as with oils and other things in life there are beliefs and people don't often change their beliefs.

edited to make mores sense and include DoT 5.1

Right then gents 

decided to buy some comma DOT4 esp bought 2 litres and flush through just over a litre,, I also bought one of those pump pressure bleeders and I must say this made life a whole lot easier,, did drivers front first just so it was shortest distance for fluid to come out of the reservoir then I just did the other 3 pipes,, all clean and look much nicer. Definitely recommend the pump thing so much quicker

Always what I use on the Yeti.  Agreed they are the way to do it. Sometimes I do the ABS Bleed procedure too using VCDS but that no doubt really is unnecessary, but with both front nipples accessible makes little difference other than needing 4L of Fluid.

Personally I have never been a fan of  pressure bleeders, I assume (always dangerous) that is a "pushy bleeder" (as opposed to a "draggy bleeder") and I wonder about the small amount left in the ABS block.  @aubrey would you mind putting a quick description of what the VCDS tells you to do for ABS bleeding please.  I'm all for a good flush/rinse through but 4 litres sounds a lot, how big are the pipes on a Yeti. 😄

 

I loathe the cheap nasty motor trade solution of using cheap nasty brake fluid (in the 20th century let alone 21st) and always had a filled watering can and wet cloths nearby as I  once dripped some down the wing without noticing quick enough and it left it's mark (cellulose paint) doh!.

I’ve not done the ABS bleed procedure on my Octavia. But I did on my Mondeo ST using forscan, that was just a case of all wheels off start the procedure and it told you what wheel and you just open the bleed nipple,, backs never really did anything as I assume they not connected to the ABS pump,, but when it said fronts forscan made the ABS pump switch on this allowing the fluid to flow through i think anyway 🤣 it made a whirring noise,,

had to do the bleed due to front brake pipe wearing through and breaking half whilst driving 🤣

The car itself does not take anywhere near 4L, it just gets wasted and pumped though as part the procedure. The procedure is you hook up a pressure bleeder with a good amount of fluid, mines a 2.5L one but I often have to add a little more at the end. You have both front wheels off and at least 1L bottle on each tubed to the bleed nipple with an 11mm Spanner Ready.

Start with both bleed nipples shut.  You simply follow what VCDS Says. Mines the ESP MK60EC1 H46 0175 ECU btw, it could be different on others. My old Roomster for example had the ABS 8.0 front H05 0002 and that needed access to all 4 bleed nipples.
On VCDS go into Module ABS, Basic Settings and on the drop down list it has Brake Bleeding
This will Repeat 10 Times, it tells you what to do on the screen. I may have the sequence muddled a bit but something like :

  Press and hold brake pedal, you hear the ABS motor kick in and the brake pedal try to push back on you, hold it in place with a firm foot hold (it's a fairly strong push back)

  Open both front bleed nipples

  Pump brake pedal 10 times

  Close both front bleed nipples

When you've done that 10 times it say pre-bleed complete. I also recall half way though another message appears but is basically the above repeated 10 times.

I then bleed 300ml out of each rear wheel nipple to complete the overall brake bleed task. 

I did a search on good old YouTube and there are quite a few examples i.e.

Thanks I thought that was the case as I read some instructions on another scan tool but we weren't do the brakes at the time, I was just curious.  Probably a belt 'n' braces and string 'n' chewing gum exercise to use it but with the cost of the ABS units and possibly some of their locations to use it or not  is possible Sod's Law 50/50 lose/win if you do or don't. 😆

 

I can't remember it being Forscan on what we looking at for a mate but Ian Duncan-Smith (well that's how I remember it) not that it mattered as the vehicle just had the Ford engine and computer bits and didn't have ABS (or servo) or electric windows or other stuff, but we had only one connector (wrong shape IIRC) out of the two and only one socket that my mate could find, week later he found the other socket tucked to the side out of sight, I stored that for the next time I done something stupid with him.  😆  Like the time I done one side and he done the other side of a bit of simple front suspension work and he finished first and I said rushing was how mistakes were made, I looked at his side then mine, I'd done mine wrong way up. 😄

Thanks.  Wow, proper modern car farting about.  I can't think a Dealership does all that at a brake fluid change, but perhaps they do (for £75?).  Video seemed good.
