Audi TT Mk1 - Replacing Auxiliary Coolant Pump - secondary coolant pump replacement on Audi TT Mk1

[@RichardBrown121]

Thanks Andy for another fantastic and informative video. I'm learning so much from your videos and also gaining the confidence to try some of the repairs myself.

[@andycharger]

Wow! That’s for your kind words Richard! I’m so glad my videos are helping people and giving them the confidence to give it a go. 👍 stay tuned for more!!!😉

[@stephenhancock2974]

You still stand out with all your instructions! I did come up with a twist on your process that made my removal and installation a piece of cake. Being an avid cyclist, I retrieved a micro-mini ratchet from my bike tools that not only slipped easily into place but left ample space to operate one-handed during the removal and reinstallation of the mounting screws. I would caution you to trace your hoses forward and aft before calling it a day to make sure you have not accidentally kinked a hose and hampered the circulation of the coolant! Andy, You Da Man!

[@andycharger]

Thank you Stephen and great additional advice! I to am a keen cyclist but do not have one of those mini rachets. I will have to get myself one!

[@stephenhancock2974]

@@andycharger Welcome, but now I've reached the other end of the rainbow! After performing beautifully on a 40km test ride I went out again today and now the pump won't turn off. What sorcery is this Mr. Wizard?

[@andycharger]

@@stephenhancock2974 it will run on for around 5 minutes after engine switch off. That is its function. It continues to cool the turbo after switch off so runs (you can hear the whine) for an additional 5 mins.

[@hrg3design905]

This worked like a charm! Took 20 minute, took longer to warm up the TT to get all the fans on to check the fan control module. Did the old screwdriver stethoscope thing and the new pump is running just fine. Great video!

[@andycharger]

Thank you buddy. I am glad it worked for you!

[@danpettipher2440]

I swapped mine out today Andy. Your excellent guide video gave me the confidence to attempt this myself. All sorted!👍🏼

[@andycharger]

Great to hear I was able to help you through the power of video Dan! Keep watching the channel and drop it a sub if you have not already done so! Thanks for your support! 👍

[@dimitriskatsalouliss3]

before we put the pump in, do we have to fill it with coolant? I saw another video and as soon as he changed it and started the engine, it made a loud noise for a few minutes.

[@andycharger]

I did not fill my pump but that does not mean it is not a good idea. It would at least ensure the pump does not run dry at all.

[@Al-qv5vs]

Thank you Andy. Your timing is spot-on. I have found out my pump is not working. So that's the next job. On crutches at the moment so it will have to wait. Good video!

[@CraigyGInDaHut1993]

Cheers. This is something im going to look into as I don't think my pump is doing anything. I don't hear it after I have turned the engine off even after driving hard. I didn't even know it had a second pump till recently. Noticed it the othher day and its quite rusty looking.

[@andycharger]

Definitely get it checked. It should have a definite whine noise coming from it after ignition is switched off.

[@CraigyGInDaHut1993]

@@andycharger it's something I'll look into. Only had the car for 2 months and it's not my daily so its not driven all the time. Been trying to sort other things out 1st

[@stevenharpervw]

I remember when I got my car the pump started to make really bad noises… and then it stopped making any noises . I ended up opening the pump motor up and cleaning the brushes. Maybe a new pump would of been better but it was a ASAP fix. Thanks so much for the shout out. I was totally surprised 😮

[@alanbaja6505]

Dear Andy, does this auxiliarry water pump should be on all the time? In my tt 225, it starts to sound even before starting the engine . And after driving remains on for around 10 minutes ?

[@andycharger]

Hi Alan. There is some “after run” for the aux pump after the engine is turned off. I believe this is to continue cooling components such as the turbo after the engine is switched off. This kicks in, even if you turn the engine on and then switch it off immediately. So I think this could cause a fair bit of battery drain on my particular car! It is normal though.

[@chrismawa]

Great video thanks! Saved me from thinking I was going to need to drain the system.

[@andycharger]

No worries Chris! I am glad it helped you!

[@monoton9597]

Do they throw code if they go bad? I heard some sort of buzzing sound when I turned my key to acc mod or after engine off but now I can’t hear it.

[@andycharger]

Yes you will hear the buzz for around 5 mins after turning ignition off that is very normal for it to go off after this time.

[@monoton9597]

@@andycharger aha, then I guess my pump is died, my engine is not buzzing anymore.

Love to see you do a thermostat change, with the clear way you explain things.

[@andycharger]

When it fails ( or if I buy a project with a failed one) I will be sure to tag you! Thanks for your supportive comments, it means a lot 👍

[@Randomtivity220]

Do you think that the auxiliary pump link would cause overheating?

[@andycharger]

It’s used mainly to run afterwards to cool the turbo I believe rather than be the main pump. I guess it could but unlikely

[@K3azzy]

does the pump fit 2000 tt

[@andycharger]

If the car is a 225, yes. The 150 and 180 does not have one.

[@paulp96275]

Great Andy simple ,straight forward instructions off to get my grandson age 7 it’s about time he did something for Pops 😂👍👨🏻‍🏭

[@andycharger]

I’m sure he can do it if you give him the torx keys. Smaller fingers to get in the engine bay! 😂

[@Bristol_boxing]

Does it run for 10 mins after u switch the engine off? Myne does not run and this weekend I will try and find the fault.. Any ideas?

[@andycharger]

Pretty much yes. Even if you switch the engine on then immediately off, it will do this. The car is trying to cool the turbo down after switch off of the engine.

[@Bristol_boxing]

@@andycharger in that case myne is not working at all no fans are on.. Only when I put the heating on they both spin..temo sits at 90 though.. But not heard the fans kick in yet when idling.. Il leave it longer tomorrow and hopefully they kick in

[@blakkno666]

Great video, mines packed up so will be doing it later.. looks easy enough (for a change!) 👍

[@andycharger]

Yep it’s a nice easy swap out this one! Thanks for the comment!

[@eddherring4972]

Going to do this on my Lilac 225. Does the 180 have an auxiliary coolant pump? I’m not sure it does….

[@andycharger]

Hi. No it does not have one on the 180 or 150 as they run a smaller turbo that does not get as hot. This pump is use to cool the turbo post spool down when you turn the car off. Good luck with the job. It’s pretty straightforward! 👍

[@eddherring4972]

Thanks for the vid, it took 10 mins because I removed the slam panel trim for easier access/visibility. The bracket that holds the pump was rusted onto the old pump on mine so I gave it a few taps with a rubber mallet around the bolt side then peeled it off the back, there are two tiny spot welds holding the bracket together and these failed so I put the bracket on the pump and zip tied it tight to make putting the mounting screws in easier. A dab of penetrating fluid definitely helps with getting the screws back in. Thanks again 👍

[@CarChris82]

great guide mate and defiantly fit a new pump as they are not that expensive. top job 👍

[@ibiochateau3263]

Hi Andy, I'm looking for the pump and I can't find it, my TT 180cv. carry? or no, Santander Cantabria, thanks friend.

[@andycharger]

Hi there. The 180 does not have the secondary pump. The reason is that Audi only included it as a “run on” pump to cool the turbo after the engine is switched off. You can hear it run after engine is off. I guess they believed this cooling was not needed for the smaller K03 turbo on the 150 and 180 cars. So don’t worry that you cannot find it. It’s not there my friend!

[@ibiochateau3263]

hahaha and I was looking for the pump like a madman, when you turned it off you could hear a beep for a while but now you can't hear anything, Greetings and thanks

[@eliwalker8410]

Trying to figure this out without paying someone and I find someone saying the 225 has an auxhillary pump but the 180 does not, does anyone know if this is true

[@andycharger]

You should be able to see the pump if it has one. I will check for you and let you know!

[@andycharger]

Hello Eli. I checked with the guru (Dom from @theparrottbros) and he advised you do not have one on the 180. Only the 225 and V6 have a secondary or Auxiliary water pump. I hope that helps!

[@pigeonguardgames507]

Had no idea there was an auxilliary coolant pump! looks like an easy job though, great vid....does the V6 have one i wonder? Looking forward to your new project car Andy, hope its a V6 ;)

[@andycharger]

Ha ha! I would love a V6. I just need to find one that is a suitable "project" as I would not want to take one on that is in perfect working order. I want to bring one back to life! I was looking at one on FB where a very nice lady was looking to sell her MOT failure but might have missed out on that. Just a 225 BAM though but that is fine by me!

[@pigeonguardgames507]

@@andycharger Andy, everyone has a 225 ;) I think a V6 is the way to go here...unless you want to mod the hell out of it then its a 225, if you want to bring one back and restore it to original I think V6, I don't think you'd regret the sound or the driving experience.....its just finding one......i doubt there are any in perfect working order, all will need a lot of work hahahahahha

[@andycharger]

You make a very good point sir! Although I am a soft top driver, I do prefer the hard top shape (shoot me down!). Anyway, you are 100% right on the V6 if i can find one for the right money. Its one to look after for the future for sure. I will see what I can find!

Hi Andy! The link for Steven is not working. I searched for him and the correct channel link would be with: harpersteven! Great video! Just bought a TT, and your videos are a big help already! If there will be a coolant leak I will know where to look! Also. There are some TT-s with no onboard computer controls on the windshield wiper arms. I know yours have those buttons, but do you know if there is a way to see fuel consumption on these cars? (I have a '99 front wheel drive 179HP, with a cluster screen witch has a line in the middle) Or maybe these are the "dumb" ones? :D

Is this the pump that sounds like a vacuum cleaner when I start my car? :)

[@andycharger]

I’m not sure. From what I understand something keeps running after turning the engine off to ensure the turbo is cooled down safely. So maybe it is this doing the work? Thanks for you comment! 👍

Yeah andy was the pump leaking because it wasnt working? Also yeah do a v6 not much content about repairing them on here thanks anyway

Hi! Thanks for the feedback. The car was throwing no errors and was not getting overly hot so i think it worked ok, just leaky!

My secondary pump just grenaded. All the coolant drained out over 100m

[@andycharger]

Ah that’s a tough break. Is the car ok?

[@90Duck]

Thanks Andy - I have a 2001 Roadster Quattro that I recently acquired, so your videos are very helpful. My auxiliary coolant pump is fine (for now) but coincidentally I just watched a video last night on the Car Wizard channel where he went through a whole litany of issues needing fixed on a 2002 coupe, including the same coolant pump. His parts and labor quote for that repair was $450, so this is definitely something I will now be willing to take on myself when the time comes! Link to the Car Wizard video below: kzbin.info/www/bejne/qpfYf2WeeNeYb6M

[@andycharger]

Wowzers! $450 to get that done? I say Amazon is your friend in this instance. Buy your own, crack open the toolbox and save yourself a fortune. Thanks for the video link, I will check it against mine to make sure he is doing the same repair. I must be in the wrong job, there seems good money to be made from the simple jobs! thanks for your support.

lots of irrelevant chatter, pitching of other youtube videos, and irrelevant pan removal. Why they put car on lift and remove bottom pan when pump is at the top is beyond me.
