Scirocco Central

Looks like a map sensor, i think in thé compressed air line after thé turbo.

If the cannister is top mounted on the engine then it has simillair drain function.

Correct the oil in the filter housing flows into the sump when you untighten the filter+cap+spindle. On the end of the spindle sits an o-ring that blocks of this port when the filter is installed.

Have also checked the bolted fuses that are mounted on thé front of the engine bay fusebox? SA1 till SA6?

Voltage regulator is behind the glovebox compartment.

On mine I had 2 leaks from the cabin air vents in both corners in the boot. The seals around it can start to leak.
I also had a leak on top of the wheel arch on a connector. I think where normally the dcc shocks electronics are wired through.

And the antenna on the roof, maybe worth to check.

My dmf is also in a bad state.
If you start it cold it’s quite loud but as soon as you put it in drive the sound goes away.

What happens when you crank up the heat to 30 C?
TDI should have an additional electric heater also that will kick in if you ask a lot of heat.
You can check thé temperature sensors with vcds.

Other possibility could be high pressure fuel pump leaking fuel into your engine block oil.

The thermostat 13 is clamped between the engine block and the coolant pipe 11.

On lhd Its above the relay carier.
Behind that little drawer in the dash.
3 big connectors go in from the bottom.

Dual mass flywheel is a weak point on this cars.
Check if you hear a rattling noise when you cold start the engine in neutral or park. If you are looking for an automatic transmission, also check it to shift smoothly.

If you let it in gear it will just slowly come to a stop.
In neutral it will slow down even less fast.
Also the road gradiënt is a big factor, if you are running down a slope my engine is sometimes stationary and needs to engage the brakes to not overspeed.

That is normal with dsg, it will coast when you lift the accelerator pedal completely.

Sounds like the cooling fans are running, AC was on?
And at start up it also heats up the cat.
Noticed a small hickup sound also.

You can adjust the bump stops with an allen key and pull them out (stronger) or push them in (weaker). Have you tried that?

What happens when you: Byte 14 bit 3 uncheck bi-xenon with shutters installed? Byte 25 bit 2 uncheck high beam via shutter active installed Try different combinations and see what it does. Also be sure headlight switch is in auto position. C43/A2 put is listed as undefined in the pinout list. And al...

That AFS is not correct, cornering lights are operated different on that one. Not by can-bus if im correct.
