Hi guys/girls,

We have lost all comms with the engine control unit on our Seat Ibiza.

It all started with an internal fault in the ABS module. The fault was 01201 - ABS pump supply voltage. we ran diagnostics and checked the loom and all was fine there, including supply voltages, so it was clear that there as a problem with the ABS module. We then sent the module away for repair which we had done many times without many issues. When the module came back we plugged it in and the fault was still present. However, this time we have no communication with the ECU at all. The battery was disconnected every time a module was unplugged/plugged in. We have checked the loom at the ECU, ABS module and between the two and everything looks as it should be.

We contacted the company who done the repair and we sent the pump back. They then said the pump wasn't repairable so we had to have a new one. We explained that there was no issues with ECU comms before the pump repair and after a few conversations with them, they supplied another recon pump free of charge.

The recon unit has been fitted and coded this morning as we would usually do but we still aren't able to communicate with the ECU. Is it possible that a faulty repair on the last unit has killed the ECU?

Below is a log from this mornings scan. The ABS supply voltage fault is now gone but the comms issue is there


Any help would be appreciated


Many thanks

Do you have the autoscan of when the ECU was communicating?

ok, hat tip to @NEtech , there is probably nothing wrong with your engine controller, other than having fault codes that you can't read at the moment. The working scan was done with a HEX+CAN, and the non-working scan with a HEX-NET which apparently still has issues connecting to those half-length marelli ECUs. I've ordered one off eBay, but in the meantime, try "Bypass CAN" in the options, and if that does not work, try removing battery power for a minutes, then bypass CAN. Let us know if that improves things as far as engine communication. The rest of the controllers, being on the CAN bus, will not answer with the "bypass CAN" option checked.

Ah ok. We upgraded our machine a couple of months ago, that's why the two scans are different.

So I tried everything that you suggested but I still have no comms with the ECU. What step would you suggest next?

I'm very grateful for your response :) Thank you

I just tried our problematic marelli here (03C 906 014 G) and it works with both HEX-USB+CAN and HEX-NET. I'm afraid until we get the 03C 906 024 BK from ebay, I don't have a solution for you other than use another interface...

Probably not helping, but it does not cost much to test.
Try and enable "Bypass DoIP" option.

did you recheck fuses ? Perhaps a short circuit happened when you replugged the repaired module back in ? Did you try and unplug abs unit and see if ECU communicate ? And please take each fuse out and check it visually :thumbs:

Thanks for your replies. I will try your suggestions today. I did check all the fuses again but I will do that again just to be 100% sure. I have tried communicating with it with the ABS module unplugged with no joy.

I will also try to use several other machines and change the options and see what happens today.

I will update the thread once I've tried the above but if there are anymore suggestions in the meantime, write them down and I'll add them to this to do list.

Thanks again for the replies :)

If you were able to communicate with the ECU before replacing the ABS module and now cannot communicate even with the new ABS module unplugged then that suggests either a fuse has blown or maybe some wiring to the ECU has been disturbed.

All fuses were checked again and are ok. The only difference between when we initially done the first scan and the scan after the unit was replaced was that we were using a new genuine VCDS interface. The previous scan was done using an older genuine VCDS interface.

Understood, which is why we're trying to get a hold of such an ECU to see if there might be some incompatibility between it and the newer interfaces.
