the first process you did of security access>adaptation>bleed cooling circuit... is that basically opening up the whole system so i can achieve a full vacuum before filling with coolant tool? service manual states i need to do something like this before filling system with coolant. thank you

That first process is setting into bleed mode, so yes - I would do that before applying pressure from a pneumatic bleed tool for sure, I think you’re definitely on the right lines there..

Hello, can a coolant or radiator flush be performed withoot using VCDS at all? this seems so complicated or rather confusing. why didn't you show what you were doing to drain the system while using the VCDs so is DIYers could learn visually? Thank you for the video btw!!

Unfortunately not on modern VAG cars buddy. It’s because they don’t just have one mechanical water pump - there’s 2 electrical water pumps too. The ONLY way to get past those is the activate the bleeding process.

Should the Expansion Tank be open during the process ?

@cropyros5363 Really good point - yes absolutely and regularly monitored / topped up.

Jon, the coolant in a Skoda Octavia collapsed. I need the replace it. I added a coolant cleaner to the cooling system. Now I need to drain the whole cooling system to remove the cleaner and the old coolant. But, just 3 l (Skoda manual says coolant is 8,4 l) came out. How to get the rest out of the system? Which hose needs to be removed to drain everyhting? I removed the hose at the right side of the cooler because it's the lowest point. Coolant should follow gravity by no avail. Thx for help.

Hiya, sounds to me as though you may have drained the coolant while the engine is cold? If so unfortunately your only way forward is to refill the coolant, start the engine and then drain when warmed up.. Hope that helps? Let me know how you get on..

Do i start this with the expansion tank cap off. With the engine cold.... or run it up to temp with the cap off then start or just do it with the cap on the whole time thanks

Best to do it with the engine warm and the filler cap off. Sorry I missed that in the video.. Hope that helps?

hello, useful video. I would like to replace the coolant in my vw tsi engine (two cooling circuits.) what I want to do is to drain as much coolant as possible. fill the expansion tank with fresh coolant. use the car while keeping an eye on the coolant temperature. top-up the expansion tank if needed. is there any risk in doing so? should I bleed the two cooling systems with VCDS instead? what do you suggest? thank you

@safewaycart Thanks for your comment - really glad it helped :-) I have heard of this being done. Personally I would not be comfortable running the cooling circuit dry with the engine running. I think the two electric coolant pumps are pretty intolerant to running dry and the engine will seriously overheat and distort the cylinder head if left without coolant for any length of time. Personally I would drain and then refill / top up while bleeding with VCDS. Hope that helps a little?

@@FixItWithJon yes, it helps (a little) thank you. it is not clear how can I possibly have a dry cooling circuit if I try to do my best at keeping the expansion tank coolantful, under strict observation, stationary car with the engine running. I mean gravity should do his job to a certain extent. I know that there are some valves in the coolant circuit and with a cold engine in theory they should all be closed in order to permit a faster warm up time. personally I dont like the VCDS method, sorry. it is difficult to demonstrate if it really works or not and you don't have a visual confirmation of how effective it is at filling all the cavities. you just have to trust the system 😒

Do this procedure when engine is cold?

Good question - no do it when the engine is warm & the thermostat is open 👍

I also had the same issue today - it would not accept 27971. It then said wait 10 minutes with Ignition on before trying again after entering an incorrect code. I haven’t tried the other codes as my VCDS offered up 27971 in the prompt bubble 💭

@madallinaturca5607 that’s really strange - I’ve honestly not sure what would cause that I’m afraid. The only problem I had with it on mine was that I had a fault code relating to one of the electric coolant pumps which prevented the second bleeding procedure from occurring - but it gave me an error message rather than just doing nothing. Maybe check your fault codes and clear them first?
