Q4 ABS pump and module

Post by Alfamuppet »

Hi all

I am still suffering with an issue with my Q4 ABS pump

Does anybody have a contact who might have a spare??

The car is off the road since 3 years now and I really want to fix it!!

Best regards

If you believe it is the pump unit, I would suggest to have an expert look at it.

Otherwise Ed Alfist is my best suggestion for a spare unit.

For me it’s definitely the Electronic module that is the issue

So any help would be appreciated finding a functioning part or suggestions on who may be able to look at it with a view to repair

I saw earlier this week on FB that Ed has more Q4's, so might be worth contacting him again.

I had all sorts of weird issues with mine, in the Marelli tester it came up as faulty ABS module. Long story short, the culprit was a bad contact on the main ABS fuse. Be sure to check that out!

The module itself, besides a possibility to physically separate from the pump (6-pin plug), is NOT openable. When you don't know what's what, it's extremely easy to damage the fragile wires inside. The PCB itself is also covered in gel, and is very rarely the culprit.

I suggest to first check the main fuse (consult tech drawings, main was under the hood bolted to the bulkhead, it's the G416 60A main supply fuse for the ABS), then check the connectors (main loom to the ABS unit, and 6-pin to the pump), then check the 6 wires leading from the connector on the ABS module to the ABS pump (in mine one wire was stripped from rubbing on the pump body).

Check those threads for more details:

It should do the trick. Best of luck!

Hi, i have one 0 265 204 006 numbered completed NOS unit for sale in ebay. I am not sure if it fits Q4 but to other 164 models it does.

I don't recall the number, but am quite sure that it is different because of the 4WD.

It is a however a good price for your unit 👍

It's beautiful and if it only was Q4 compatible I would probably snag it :D Sadly, as Alfan said, Q4 has a dedicated module 0 265 204 007, later substituted by 0 265 204 008.
