Dpf help

[Muppet010109]

Hi guys.

Just wondering if anyone could possibly help me.

I've noticed an increase in black sut from my exhaust and a decrease in power and was thinking my dpf might need cleaning. I haven't been doing very big journeys lately so it's not been getting a good enough run to clean itself.

However, I haven't done this yet so I don't know where the dpf is located.

Any help would be greatly appreciated, pics too

I have a "57 plate, 2.0tdi, black edition sportback" for reference.

Thanks in advance

I’ve obviously a petrol but just started using redex advanced cleaner on the S3, and so far I can tell you it’s a big thumbs up.

Worth a try for your DPF issues maybe?? Why not look at their write up on how to resolve DPF issues: https://www.holtsauto.com/redex/support/can-i-just-take-car-mechanic-clear-dpf/

Ah, redex. I didn't even think of that.
I'll look into it
Thankyou

Take it for a Italian tune in 4/5 gear for 20 mins. This may regenerate the dpf.

Excessive soot could also mean that the car is over fuelling, so injector issues etc.

Best way it to get is scanned to see if there alre any codes. If there was a dpf issue the dash light would be on.

I didn’t think diesel 2007 cars had a DPF unless it’s a 170 engine.

I wouldn't expect to see much evidence of a black soot build-up on the exhaust tips on a modern diesel with DPF. Typically, the exhaust tips stay clean unless the DPF has been removed. Soot is trapped in the DPF where it is burned and ejected as very small ash particles. You get more exhaust tip soot build-up on modern petrol engines. If you're not getting any warning lights on the dash, as suggested above I would first try some cleaner in the system followed by a good run with the revs kept high to create plenty of cleansing heat.
