Hi, nice video :-) How many KM / how old ist the AGR Cooler an is it better for it to drive high speed oder moderate speed ?

[@kennedysgarage3281]

They seem to fail at around 4 to 5 years and I don’t think driving style matter’s too much, it is just part & parcel of modern engine design unfortunately ☹️👍

[@kickersubspwn]

Would it not be easier dropping the gearbox to gain more access? My dpf light came on a few days ago so I'm gonna have to tackle this eventually and I've only just changed the clutch and flywheel 😓

[@kennedysgarage3281]

It might be a good access point but there is quite a bit of work at the side of the engine also. It could work though 🤔 Let me know how you get on 👍

[@antonnilsson7100]

working in a dealer ship i can confirm this is not easy, it took me 1 and 1/2 day, i took it all from up side the engine bay only

[@kennedysgarage3281]

It is quite an awkward job Anton, this was my 1st one and I just thought it would be easier from underneath. But well done on doing it and thanks for watching & commenting 🙏🙏👍

[@Vorrester]

Has Audi ever updated this cooler to be less sensitive to failure? I heard somewhere that they supposedly added a hole somewhere so that it wouldn't clog so easily, but from what I can tell the parts number index has always been "AA" for most cars.

[@kennedysgarage3281]

The internal holes in the cooler have gotten slightly bigger and square rather than round in shape. This is supposedly going to resolve the issue 🤞🤞🤞

[@Vorrester]

@@kennedysgarage3281 Very interesting, thanks. My original did 170k kms or 105k miles. So quite likely the new one will have enough life until the rest of the car needs to be scrapped.

How much did it cost ??

[@kennedysgarage3281]

An EGR cooler replacement on one of these is going to cost in the region of €1500. Not cheap by any means 😬😬

[@evansmarts775]

What a nightmare job mate, I know I am asking for too much but any chance you could include the code or data or smptoms that led you to change the cooler, other then that video is top notch very detailed thanks alot Kennedy 👍👍

[@kennedysgarage3281]

It was my first one so I might tackle the next one different . I can’t remember the exact codes but they were Catalyst efficiency codes, I’ll try to remember to check scan tool for codes etc. tomorrow or so 👍

That's criminal Audi know about this problems it happens on every A6 after shocking 40k miles and Audi didn't fix the problem even the car is under warranty they said it's a taxi so you do too many city miles even I'm airport taxi so no town miles so they void the warranty and had to pay thousands in different garage for this Audi Cambridge babraham rd, thank you.

That is awful 🤷🏼‍♂️

Hi mate did you get it sorted

[@sylwek130]

Do you have to change egr valve also? Asking cause have the same issue

[@kennedysgarage3281]

I haven’t ever needed to change the EGR valve itself, it is only the cooler that blocks 👍👍😉

[@sylwek130]

One more question cooler will be changed next week. Also I fell fumes inside on idling especially. Turbo is covered with the soot also is that because of the egr cooler? Thank you

[@kennedysgarage3281]

@@sylwek130 possibly not, that seems like a leak somewhere around the exhaust manifold. This leak could be your problem & not the cooler or f it is leaking that bad 🤔🤔

[@sylwek130]

@@kennedysgarage3281 went to Audi and they diagnose the car and said that egr cooler. That's the fault code I have in the car P2002 Diesel Particulate Filter Efficiency Below Threshold Hopefully they are right. The smell is not always and especially when is cold.

@@sylwek130 that all sounds correct but make sure whoever repairs it does the exhaust system leak while working in that area 👍👍👍

[@ionprocopenco204]

Hello, recently i had a very common problem (like many posts on this forum) with the egr cooler. But after replacement with an NRF (firm) part, i found that everyday i lose about 100-200 mililiters of coolant and it's going to the exhaust (somehow). If i drive 100-200 miles a day, at the end of the day i see that coolant level is a little bit lower than in the morning... but next day it's 2-3 times lower... In the morning the exhaust is white smoking (hard enough to make a difference from smoke and mist) for about 5-10 minutes. And the smoke smells like coolant. So i don't know, is the problem in NRF egr cooler? Because before changing my car was not losing any coolant ( i check coolant level everyday). And it is 100% internal leaking. It started in the first 5 minutes after egr cooler replacement. But i don't know, it's the cooler itself, or boys from the service didn't put back some gasket... I asked them, they said they used old gaskets.

[@kennedysgarage3281]

There are 2 water hoses that join onto the cooler externally, a feed & a return. So if you feel it is leaking into the exhaust it is more than likely going to be the cooler itself & definitely not a gasket. Hopefully this helps 🤞👍

[@JDNSAUDIS]

Watching this realising i didnt need to drop the engine to replace the turbo 😂

Massively I work on these a lot this is the second one I’ve done where I’ve dropped the engine, I was just too pessimistic and said that’s not gonna come out of that hole, I prefer the 3.0 tdi turbos 😂
