We have a issue with this golf,came to us with dpf light on and coil light,code stored.

p2002 particulate trap bank 1 below thresold.

we replaced dpf 2 months ago as came in with dpf fault[not vw part]before dpf was fitted customer had fitted a new egr,we have checked cooler and actuating valve,air flow meter,until these codes clear car will not re gen itself.found blown fuse 4 which was wiring rubbed through on air con switch,on egr valve we have blue wire but cant see if it should be a feed or signal wire or earth.

Hi,
Test the DPF pressure sensor, I've had a few of these faulty?
Always what scanner are you using ?

if EGR cooler is restricted you would get that code , a test i like to do is bring up in live data MAF g/s and EGR data,

look at the MAF and the % EGR at idle , the transporters i use this test on will command 60 to 70 % EGR at idle for a few mins before they go to 0

when its at 60% or so operate the EGR cooler Bypass valve (The vacuum operated black plastic actuator on the top) and see if the MAF g/s goes down by a significant amount, .
if it does it shows that the cooler is restricted.

this test will not work on vehicles that do not command EGR at idle and i am not sure how good it would be at higher RPM's as i have not tried it.

Seen a few DPF faults now with non genuine units that aren't up to the job.
Same with so called aftermarket cats even the approved ones,
Couple of months ago we had a car that couldn't even pass an MOT straight after a new cat fitted.
Gave up and fitted a genuine one then it went straight through.
We only have profession cleans done or replace with Genuine now.
