Hi guys,
New member and first-time poster. Having received a lot of insight from this forum and a Civic forum these past few weeks, I wanted to share my recent experience and if possible, seek help and help others out.
A little bit of background on my DPF issue:
I have a 2015 1.6 i-DTEC - EX Sensing (160hp, 9 speed AT, 115k km - 30k km of which are mine, 100km daily return commute on 100km/h road).
A couple of weeks back I started encountering issues. One morning the car wouldn’t start. Engine cranked but never fired up. No warning lights or trouble codes present at first. However, after a while of trying to start the car, I managed to pull DTC error code: P065A. I believed this was possibly related to a low battery (likely my many attempts at starting the car causing it to drain). I hooked up a battery charger and left it overnight.
The following morning, I checked the battery was fully charged, cleared the error code and started the car successfully 1st attempt. I suspected the cold nights here (-23c the night before the trouble started) had caused some battery drain, so thought no more of it once the car was running again.
However, after running the usual 50km trip on a 100 km/h road into town, the ACC light illuminated on the dash telling me the adaptive cruise control was disabled. Once stopped, I tried scanning for error codes, but none were present.
On the return trip I got my first indication of the real problem, the dreaded DPF! light, the one with (!). I found this odd because from everything I have read, it seems more often the case that the DPF light without the (!) illuminates first, warning that a regen is needed and once the light with (!) illuminates, the car usually goes into limp mode. Mine never did and still hasn’t gone into limp mode.
My basic ELM scanner and app couldn’t retrieve much in the way of info or stats for DPF status other than P24A4 code (PM accumulation quantity excess) and a code that I cannot find much info on U3F00 (40)? I tried clearing both codes but the P24A4 remained present.
Searching online I came across a very helpful thread on a Civic forum with many people sharing similar experiences.
Long story short, I opted to buy one of the HDS HIM boxes from Aliexpress and setup the vintage hardware to run it!
The stats pulled from the car show a calculated PM value of 31.5g and 1136km since the last regen.
I wondered if the ‘non starting’ a few weeks earlier was the first sign of a clogged DPF as that PM value is rather high? I am of the understanding that passive regens happen somewhere around 7-10g.
So, now to my present situation.
I have data suggesting a clogged DPF is the first issue at hand.
I can force a regeneration using the HDS HIM box but feel doing only that, would be in vain. I’m considering removing the DPF after the regeneration to perform a thorough clean and flush. The idea of running the forced regen first is to turn the clogged crap into ash, thus making the flush more effective??
The Civic forum thread has a few examples of guys having done the removal, and if the DPF location on the 1.6 Civic engine is the same as the 1.6 CR-V engine, then removal seems a relatively simple process.
After doing this I guess I will learn if there is another underlying cause for the DPF issue by monitoring the data regularly.
So, the questions I would like to ask are:
Firstly, am I getting ahead of myself and missing something, a possible underlying issue linked with or causing the failure to start or the jump straight to a DPF (!) light?
Does anyone know of any danger/damage that may or may not be caused to the engine by forcing a regeneration with a high calculated PM (31.5g)?
Has anyone here performed a removal of their DPF for cleaning? If so, is the process as simple as the Civic, done from the top of the engine?
Alternatively, although not my preferred choice given the high level of PM in my DPF, has anyone tried something like the ‘on car’ deep clean JLM 2 part clean/flush, which is blown into the DPF under pressure (5 bar)?
Thanks in advance for any help and advice.
