While change the oil filter on my 2011 TDI Q7 one of the plastic coolant Tees broke. Any help with sourcing information is greatly appreciated!

Assuming there is no hidden check valve, any proper sized T from an auto parts store would do. Don't forget the spring pinch clamps.

Better it broke in the garage than in the middle of some highway.

So below is the sourcing information for the coolant hose.

PN 059121086Q








VW part# is the same

Pretty sure they call this the "part designed to break when owner tries to change their own oil"

One of the things that drew me to German cars was that BMW puts their oil filter, easily accessed on the top of the engine. Audi, as I'm finding, is not BMW. They do the same, then block the oil filter with a rat's nest of cables, wires, and piping, defeating the purpose of putting the oil filter there.

Is there not a way to edit a post here?

I had a follow up question, to this, if this pipe breaking can insert air into the system, requiring it to all be bled after repair ? Seeing some A/C issues post repairing this myself with an aftermarket T and coolant host that is the same inside diameter.

I use a vacuum fill tool to refill coolant. It prevents a lot of the air trap problems in some of these engines with complex coolant passages. From a cheap version such as to more expensive name brands are available. You do need a decent air compressor with good CFMs, but a pancake 2.3 cfm seems to work ok, could be better.

It is too bad German manufacturers cheap out by using these plastic parts. For a tee like this, I agree a parts store or Home Depot brass tee would be a better replacement, but that would be too expensive for Audi.

Thanks for the reply. It's funny, I'll do almost any repair on a vehicle, but pressurized coolant systems scare me. If you screw it up, it can really damage the vehicle.
