PolarFIS - Where to find CAN Gateway (J533)?

[lexc]

Hi all,

Does anyone know if our cars have a separate CAN Gateway/ J533 module like most of the other VAG passenger cars?

I have stripped almost everything on the driver's side interior (RHD) and have not yet found it (in my Audi TTS this is located behind the instrument cluster). I did find the Body Control Module though.

After comparing HW part numbers (7E0 937 090) from a VCDS scan as well as looking through SSP 561 it seems that J533 and J519 (the Body Control Module) share a part number, and might even be integrated inside the same unit?

The below image is what I am looking for/ expecting to find when looking for a J533 / CAN gateway


Below is what I found BCM (7E0 937 090)

Its part of the BCM, not a separate module

Thanks @Pauly, happy to know I've not gone crazy.

My next quest now is to find a pinout for this unit as I will need to make a custom adaptor for my PolarFIS which uses the 10 pin connector that's usually found on the J533 units.

Polar advised the unit is compatible with this vehicle after I sent them A VCDS scan, but I suspect they did not realise the harness would be different.

That's very interesting... looks like you need hook up databuses.

Just to update everyone, I will attempt to build this cable as soon as I order the OEM connectors. But I think I have had success with the pinouts and have added them below.

Will update on part numbers for connectors to build the adaptor cable once I get there

EDIT: "6R0 937 700 A (white)" is the male connector that is needed. I am a but stumped for the female connector as that's essentially part of the BCM's moulding. Might need to find a dead BCM and hack that piece out of there.

J533		J519 + J533 BCM combined
1	Battery (terminal 30)	39
5	CAN LOW Comfort	21
6	CAN LOW Powertrain	18
9	CAN LOW DIAG	22
10	CAN LOW INFO	57
11	Ground (Terminal 31)	38
15	CAN HIGH Comfort	20
16	CAN HIGH Powertrain	19
19	CAN HIGH DIAG	23
20	CAN HIGH INFO	54

Any update on this?

Any update on this?

Found it a bit of a struggle to source connectors without paying €90 shipping on a €0.50 part so decided to just clip and splice into the harness.

Might attempt this tomorrow and will let you know outcome.

It is a bit pricy approach but I am curious about your experience with PolarFIS.

Has Still nobody ever tried this out ?
