The Audi Thread

Well it looks melted on the one side and the other side it looks like someone got angry with an ice pick.
The side where the valve indents are I’m not sure. The bottom side is from detonation. I’m surmising that the one valve stem seal was leaky, and oil kept being ingested into the engine which lowers the octane rating of the fuel. Just a guess but that’s definitely on the way to a fully melted piston
 
What would cause that?

That looks like damage from a 'foreign object' finding it's way in to the combustion chamber and being constantly squashed between the head and piston as well as finding it's way down the side of the piston. So either the engine ingested something it shouldn't have or something came apart inside like a valve lip, spark plug tip or more likely the ring landing which is a common failure point on these engines.

That was my thinking as well which makes perfect sense, but the melted part is really strange and worrisome.
 
the piston looks just as shocked about things as we are.

How do the valves look seeing they took a knock.
Valves looked okay, but they all had wear around where they pass through to the combustion chamber (where the seals normally sit) so they were replaced
 
Turns out my high oil pressure issue was real.

I used an Equus gauge that I borrowed that can measure up to 8 bar, and the needle shot off the gauge face when I cranked the car:ROFL: so definitely have a high oil pressure situation that I need to sort out. I'm hoping that I can make it work using a 2.0 FSI oil filter housing as these seem to have pressure release valves built in which the TFSI oil filter housing does not have. There are some small differences, like the mounting of the oil pressure switch being mounted on another spot and the crank case breather hose being on top as opposed to the side, but those can be worked around as the housings are similar enough.

I think I detailed the reason for my high oil pressure previously but basically, the original EA113 oil pump with balance shafts was removed and a 1.8T pump was installed instead. These do not have pressure regulators in them though, so somewhere in the system a relief valve needs to be introduced, which I am hoping the FSI housing will remedy.

I got the bumper buttoned back up today and gave the car a good wash, then took it for a trip to the local Takealot depot to pick up some goodies and to see how it behaved on its maiden voyage.

It felt really strange sitting so low (compared to the wife's Picanto) but it pulls well and the trip went well with no drama. I'm still running it in (got a piece of masking tape on my cluster reminding me thereof) so I'll be taking it easy for the next 1000km, after which it will get another oil and filter change.

At a later stage I will sort out the cosmetics, but for now I am all too happy to have it up and running again.

Great alignment on those opened windows.
 
Had to enable that in VCDS on my B6.
Awaiting my clutch kit next week
Where did you end up ordering from? I see there’s a B6 Avant being stripped at a company somewhere in Sidwell, might go hunting for some compatible parts soon as I need a few odds and ends that never made it back to me after I got the car back
 
Went with Goldwagen in the end.
Saw one advertised on FB Marketplace being stripped, but what I was after already sold.
 

What Is VCDS and Why Every VW and Audi Owner Needs It - MUO​

If you own an Audi or a VW, this software could save you thousands every year.

VCDS by Ross-Tech is a diagnostic software tool specifically designed for Volkswagen Group brands. Its name stands for VAG-COM Diagnostic System.

As suggested by the name, it is a highly specialized tool, offering dealership-quality diagnostic functionality for regular consumers.

This makes it much more capable than standard OBD-II scanners.

VCDS is a must with VAG cars, not only for diagnostics but also for tweaking stuff like how many times your indicator flashes when using the comfort flasher, how long your coming-home lights stay on, disabling features you don't need (headlight washers) etc.

It's pretty pricey though, I think around R4k for one with a three-VIN limit. But well worth it if you are planning on doing your own repairs
