Audi TT 1.8T 225 thermostat change guide how to BAM APX 

Haha… well here I am… 3 years after buying my first TT mk1. I first watched this years ago. Lots of these early videos are 100% re-doing with what you know now. 💙🇦🇺🤜🏼🤛🏼😎🍀☮️☮️☮️☮️

Great video. Very helpful. Just some considerations... I replaced mine yesterday. It took me 3 hours. I didn't have any major problem. I did it with the car road ready. The access to the screw holding the lower part of the thermostat housing is very difficult. Also to remove the alternator cable holding screw. I would advise having tool with magnetic properties. The probability of screws falling in to the engine compartment is very big. It happened to me. Also the oil plastic pipe was already broken, but it was not visible before starting taking things apart and as I pulled it out it broke in pieces. So just have one ready if yours was never changed. Not impossible, but not easy task. Arrange for the right tool before starting and have agile fingers. Good luck.

Very useful video, need to do mine soon so this makes it so much easier.

Well,i dont know how to thank you,mate...this was extremely helpful..thanks,once more!!

Well done for doing it all one handed 👍👍👍

Great video and props for doing it one handed 👍

Very helpful, thanks mate!

Excellent guide, job was completed and using the wobble head/ hinged extension to remove the thermostat housing 10mm bolts, I’ll see if I’ve seated the O-ring correctly, my only concern, very helpful BWS.

Great video all the way from start to finish. Thank you very much.

Really useful video, thanks.

This video saved me $280. Couldn't get the wobble socket to work. Used a crazy screwdriver/socket/adapter combination to get the bottom screw from the housing. Can be done though. Thanks for the video.

Perfect Manual, i have to change in few days

Excellent how too !! Very accurate ,, deffo do get the wobble extension tho , did mine in less than an hour

Quality video, cheers.

Good video. Many thanks

super video !!!! THANKS

hi and thanks for your interesting videos. do you know why in a couple of manuals I read that the valve arch must be positioned vertically? Thank you

Great video, thanks for sharing.

Having seen your other excellent video on removing the alternator, I did that first. With the alternator out of the way this job is a breeze ;-)

Have you got a video on water coolent sensor as i ve got a p1296 code on my tt cheers mate

Cheers dude, followed and fairly simple. An electric ratchet makes light work of this job. Done in under an hour.

can you help me understand the direction of coolant flow through these engines, is it: cooled water in through thermostat opening and hot out via coolant flange at side of head? or the other way round? - thanks

This looks way easier on video when you have the whole front end off, I tried this without taking the radiator and fans off and damn is it hard, way too tight to fit my hands. I initially wanted to comment that you must have small hands (or maybe I have larger hands?), but in any case the bottom bolt on the thermostat housing was extremely difficult to get to, even just to put on the socket to tighten/loosen it! Marco Cadima also brought up a good point, the alternator cable holding screw was very hard to get off/on. On to other fixes on my tt now, water pump, timing belt, friction plate and clutch slave cylinder, wish me luck! Cheers!

Many thanks

Good video ,not as difficult as Haynes makes out !

Is the thermostat in the Same Spot By the 1,6l?

Hello mate got a code come up p1296 after the eml light come on ,i ve changed the the sensor and still got the eml on could it be the thermostat stuck open as well ?? Cheers mate love the vids

How can i find the metal pipe that connects on the right of the thermostat? Any idea on the part number

Hi mate once disconnecting the battery will you lose all memory I.e radio airbag etc.

Great Video Brian, did mine last night and only took a couple of hours. Quick question, how tight should the bolts be done up on the thermostat, the bottom a lot harder to tighten the top one?

PLEASE HELP! I was considering using a lower radiator hose heater because it is very cold where i live. My question is, Does the thermostat go between the lower radiator hose and the block? (is it located on the suction side or hot side?) im told saturn and audi are known for suction side thermostats that will prevent the flow of a lower hose heater.

Where is the coolant drain nozzle on the radiator? I’m trying to do a coolant flush and I can’t seem to find where it completely drains from.

Just changed to Bora , it Took 2h, 1h to find tools from around engine:)

Another job I had planned today that after watching the video realise won't beable to do it because of my stupid fin hands. It's like even little stuff is a nightmare on these . Just praying mine goes through its mot OK ( had it checked and done the bits that might come up) so hoping it'll pass . But you never know itz a different garage. I'm juts hoping it does. All my eggs are In the hope it keeps running unitll I can afford a different car basket now haha

thanks

I’ve done this before but can’t remember fully. My car has just had its coolant redone as I had a leak, now the leak has been sorted the thermostat has gone (normal), could I get away with just taking the hose off, replacing the thermostat and the housing with an aluminium one without draining the whole system? Can I just top up any fluids that do leak out while changing? Cheers.

Just dropped my bottom bolt down behind the alternator mounting bracket 😬 m7 ?

😎 cool

Did mine today. Helpful video. Note: there’s space under the alt if you use a longer extension which is nice if you don’t have a wiggly bit.

My job tomorrow. Hopefully my head gaslit hasn’t gone

hi , do you have any guidence for replacing the waterpump on this car ?

I do have a tt myself. Watching this tells me not to try and do any work myself .just book it into my local garage and pay. Not the easiest of engines to work on

4 years later... What thermostat do you use? Looking on Euros but there's a few different brands... Cheers

My thermostat is stuck open. I’m assuming I’m gonna loose a lot of coolant lol.

The bolts can also be taken off with a short allen wrench ;)

Damn, I need to remove the entire front end to replace a thermostat?

Why don’t you invest in a camera that clips on topOf your head via Bluetooth make life easy

buy some decent tools :/
