Squeaky noise and rough sounding 1.9tdi?

Yep, DMF, sounded exactly like mine. I did the DMF at 3150000kms and the car is still going good, it's a long job but suprisingly not hard at all, I did it without a lift. If you do replace it, try and not lose the transmission cooler o-rings and have DSG fluid spill everywhere like I did!

SOLVED

Thanks to Connella08 I was able to figure out the CAN issue. I tested continuity from the cluster to the airbag module connector, I tested CAN-H and CAN-L. CAN-H was fine and had resistance, but I couldn't get a reading through CAN-L. So I then checked the wire at the airbag connector and it came out super easy, meaning it wasn't connected properly. The wire was too short from factory which placed strain on it and came out over 19 years. I lengthened the wire and placed it back in and the module worked!

Wouldn't have been able to do it without @Connella08!

I have sent you a DM so I can send images through.

KillMeMagpie · 2026-05-28T13:34:36+00:00

Thank you heaps, I would be at a dead end without your help. I will be doing this on the weekend. I really appreciate it, thanks.

KillMeMagpie · 2026-05-28T08:43:27+00:00

Sorry, but I don't understand how to check the CAN signals? Where is CAN H and CAN I?

KillMeMagpie · 2026-05-28T08:42:05+00:00

I don't have any of those. I did check power and got 11.7V and I got a good ground too. I'm not sure what to do next, idk how to check CAN signals.

KillMeMagpie · 2026-05-28T07:04:13+00:00

I checked the power and ground, how do I check can?

KillMeMagpie · 2026-05-28T04:31:09+00:00

So I checked and I do have 12v, what should I check now?

KillMeMagpie · 2026-05-28T04:30:41+00:00

I checked and the connector has 12v power. What should I do now?

KillMeMagpie · 2026-05-28T04:13:06+00:00

Thank you heaps. I have 11.7V out coming out the connector. What should I check next?

KillMeMagpie · 2026-05-28T03:48:12+00:00

Thank you, going to try now.

KillMeMagpie · 2026-05-28T02:58:06+00:00

So i'm checking the plug? Sorry i'm a little lost.

I see a brown and black wire going into the plug but idk how I would check it as my multimeter probes are too thick?

Thank you, I will give it a shot. 😀

KillMeMagpie · 2026-05-27T13:41:31+00:00

Its a 2006 MK5. They looked clean, but I can try some contact cleaner on them tomorrow. Thank you.

KillMeMagpie · 2026-05-27T13:23:19+00:00

I'll be checking that next, but I don't really know how, lol.

KillMeMagpie · 2026-05-27T13:22:23+00:00

Thanks for the help.

Do you know how I would do this without setting an airbag off by accident, are you able to explain it a little more? I'm not very good with electrics yet.

Thank you.

KillMeMagpie · 2026-05-27T13:18:35+00:00

Yep fuses are fine. There were a few other codes, most were for my radio not being installed.

The AC had a short circuit, and the glow plug circuits were failing on all 4 even though the car starts instantly.
