you can replace just the ECM if I remember correctly. However, if you're buying this used, they often come attached and sold as 'one'.

You'll need someone quite handy to code it all in once you're done.
Yeah, I've been looking for a used one and they're all sold as one. Cheapest I could find is like $300. I can just remove the module and use just that one. Thing is, if I just switch out the module then I've to have the exact same one(number) as my old one. But if I switch out the whole unit with the pump, then there's a couple of alternatives I think.

All you need to have to code it in is VCDS no?

I'm sure I've got a couple of modules as Spares so if you can post your modules exact codes then I'll have a look

It's better to have the part numbers match, as there is less to go wrong. I think there are other units you can use but you must read up first.

programming should have (in theory) been a straight forward task, but the garage could not do it.

In the end I called a chap over who does all VAG coding and he sorted it. It's worth pulling the code first before you swap/replace.

My car would often throw up ABS module codes - loads of other related bits would be affected.

Yeah, I'm waiting to get my module back from the 2nd repair attempt. If that doesn't work I'm crossing my fingers that @Architex_mA8tey has one laying around

I think I got the coding part figured out so that shouldn't be a problem

Hello again. Got the module back from repair and it works Managed to get rid of all the warning lights in the middle display and fault codes regarding the module.

However, a new problem showed up. After I calibrated the air suspension(successfully), a new fault code showed up in the ABS module:

01435 - Brake Pressure Sensor 1 (G201)
012 - Electrical Fault in Circuit

Wonder if it was because I did several calibration attempts and the car was going up and down, maybe the wiring couldn't take it. I checked in VCDS and it has a constant pressure of 291 bars, regardless of if I press the brake pedal or not. According to VCDS that means "short to plus". I tried to remove the connector from the sensor and it still showed 291 bars. Does that mean it's the wiring or could it be the sensor?

Also, the ABS light(yellow), ESP light and parking brake warning light now appears. The only code in the parking brake module refers to the ABS module and the only code in the ABS module is the pressure sensor code. So could all of these warning lights be because of the pressure sensor code?

Isn't the sensor internal in ABS pump? So not sure what you unplugged.

After searching online it looks like it is separate sensor on that can be changed on ABS pump on D3. You can probably measure resistance at the pins. I don't know what the values should be but if it is short or open you can be pretty sure it's faulty.

You mean checking the resistance between the 3 pins on the sensor?

Yeah, replacing the pressure sensor didn't solve the problem. If that wasn't enough, all the brake fluid went seeya from the ABS unit so I had to bleed it all. YAY! It's all pointing to the ABS module. One problem gone, a new one shows up. Guess it's time to try find a new/used module

Phaeton ones look the same but are much cheaper, I wonder what the difference is ? Their part number starts 3D0.
