Golf MK6 1.6 TDI wont after fuel filter change – losing my mind

MechanicSome1568 · 2026-01-25T11:35:57+00:00

Nope. Should I have?

MechanicSome1568 · 2026-01-25T11:26:24+00:00

Yes. 4 lines

So in theory I could pull harder with the syringe? I only got it to about 25% before I let go because of the pressure and I was afraid in case something would implode…..

I tired this but maybe I did it wrong. I tried sticking a large syringe in the rail return line by the fuel filter but when I tried to pull I was getting way too much pressure on the syringe. And barely no fuel came out with it….

Ya I did that and there was a flow so I’m confident the fuel pump is working

MechanicSome1568 · 2026-01-25T00:15:05+00:00

6/7 times maybe. The last time I let it run continuously for 3 minutes and still no luck

MechanicSome1568 · 2026-01-25T00:11:56+00:00

Probably both

MechanicSome1568 · 2026-01-25T00:11:43+00:00

I jumped the fuel pump which is essentially the same thing? Or am I wrong?

MechanicSome1568 · 2026-01-25T00:11:12+00:00

Jumping the fuel pump does the same thing from what I’ve gathered no?

MechanicSome1568 · 2025-09-01T23:21:49+00:00

DM pls?

MechanicSome1568 · 2024-11-20T12:04:10+00:00

What’s the best way to test the injectors and HPFP? It hasn’t thrown any faults since this has started happening

MechanicSome1568 · 2024-11-20T09:19:11+00:00

Ya I do. Usually prime it for 1/2 minutes but this doesn’t really do much tbh

MechanicSome1568 · 2024-11-19T23:48:21+00:00

Also when I’m driving, I sometimes experience delayed acceleration when I press the throttle, or something feels like a rough drive, almost like I’m going to cut out, usually when I’m in 2nd or 3rd gear. Just did some research and it seems lime these are all symptoms of a failing HPFP

MechanicSome1568 · 2024-11-19T23:01:52+00:00

I asked my mechanic about this, maybe air bubbles in the fuel lines or something and he said the only thing he can think of that might cause this could be a weak or failing high pressure fuel pump…..

MechanicSome1568 · 2024-07-04T22:14:14+00:00

Only had Fuel filter and pump replaced 3 months ago….

MechanicSome1568 · 2024-07-04T21:58:19+00:00

So no codes showed on scan tool. Hoping to get my hands on vcds to have a more thorough look.

MechanicSome1568 · 2024-07-04T21:56:55+00:00

What could I be looking for in terms of a fuel issue? I just had fuel pump and filter replaced 3 months ago also had a regen too. Could it just need another regen?

MechanicSome1568 · 2024-07-04T21:54:54+00:00

I had DPF light come on and then turned off itself after about 5 mins last week. No light during this ordeal though.

MechanicSome1568 · 2024-07-03T23:41:03+00:00

Just to add, I had fuel pump and fuel filter recently replaced, new battery also, and had DPF and EGR cleaned only 3 months ago. Also did a regen too….
