I was losing coolant in the V of my Audi Q7 TDI. I tore it apart and found a cut in the coolant hose going to the oil cooler. So that was simple. The question I have here is does anyone know of a kit to reseal all the components in the V? or what all seals do I need to do this? What else would you recommend doing considering that i have it tore apart?
Thanks

it is a 2013
Here is the comprehensive list of every seal you need for a valley job. Includes intact tract hoses which are theoretically optional but good to add

There are several options for cooler delete if you want to go that route. The time to do is it when you are already valley anyway resealing everything.

$220 (US) - SUS TDI (me) https://sustdi.com/product/3lg2egrkit/
$250 (US) - TDIUpgrades -> linked by Danmin
$290 (UK) - Darkside https://www.darksidedevelopments.co.uk/products/egr-cooler-delete-kit-for-3-0-tdi-v6-vehicles.html
$1250 + Brain Hemorrhage - German diesel motorwerks - No website or brain cells. Just call them 10 times and then wait 6 months for invoice.


Notes if you buy TDI Upgrades:
* Throw the clamps in the garbage. Buy sleeved silicone
* Throw the gasket in the garbage, buy OEM circular seal or leave stock
* Hoses are not cut to size and also due to routing will rub on the manifold or support bracket and eventually rupture 100% guaranteed. Suggest to buy a 90 degree elbow and follow sustdi routing.


Notes if you buy Darkside delete:

why does the website say RESEAL KITS ARE NOT CURRENTLY AVAILABLE!

I'm looking at the following kit.
Gen2 EGR Cooler Delete Kit (3.0 TDI Gen2 2013-2016)

Also curious if the above kit also includes the following kit? or don't i need that?
Full Billet Delete for Coolant Bypass (3.0 TDI Gen2 2013-2016)
Thanks for all the help!

no ETA on restocking those as it is extremely long lead time to get qty of each parts.

its optional add-on to egr cooler kit but not included in the $220. but majority of people get it. its possible to replace this valve without removing intake manifold once egr cooler is gone so you can also defer this part of the job to later if you really like.
