Leon FR 170 DPF Help - VCDS

[DuV]

Hi all, recently bought a 56 plate leon fr tdi for my wife, and only afterwards read more into the dpf - oops!

Anyway - is anyone able to help me with the following screen shot:

as it confuses me in that its stating its never had a successful regen, that its regened 0.0s ago?!

also with it being on 47mg and the limit being 60? What happens when it hits 60? DPF removal time?

thanks in advance!

ps if anyone is local to me (Leicester) im happy to repay any help with plugging into VCDS

wiki.ross-tech.com/wiki/index.php/Diesel_Particle_Filter_Emergency_Regeneration have you followed this procedure?

Couldn't yet put link as not enough posts, read through here and this will help.

Ignore LisaFR's post, that has nothing to do with your screenshot.

I'll wait for someone more experience to come along. On my FL CR engine you can't view that menu only advanced measuring blocks. It's possible you can't view that reading though.

Ok thanks ;-)

 

[lisafr]

You can if it is not a pikey version.

That link will tell you how to regenerate your dpf and this will bring the dpf load down to zero, if it doesn't chances are you would have a fault but that would be listed in the dtc's.

Done a regen. All cool on that. It's more the fact it states successful regen = 0 that's all

 

[lisafr]

Also Duv if you want help we have a garage in Burton upon Trent and you are welcome to come over and we can show you what to do.

 

[lisafr]

If you have done the logging code and regenerated properly then the load should be at 0.

 

[lisafr]

If logging code was not done at time of regen then the car will not go into the forced regeneration mode.

 

[DuV]

Yea its at 0. It's just the other field that's still on 47 mg. forced regen was done properly. Light came on. Drive at right speed etc. light goes out and at 0 thanks for offer! Burton not far and have friends there!

Oh sorry just relooked at screen shot and seen it was the particle filter carbon mass not particle load as I was busy when I first looked at it.

It looks like you have regenerated it correctly, the level of carbon deposit in the particulate filter is constantly monitored by the engine control unit which calculates the flow resistance of the filter. To determine the flow resistance, the exhaust gas volume before the particulate filter is compared with the pressure difference before and after the particulate filter and is recorded as a ratio. With this in mind you may have an underlying problem with your dpf exhaust gas pressure sensor and I know this is a common problem.

I heard this was a recall at one stage so it might be worth speaking to your local dealer to check.

what's the fault codes on the screen shot, if there are any? I have the fault codes from mine on email, I recently had the exhaust pressure or dpf sensor as its sometimes called, replaced

one of the symptoms I had was 4 regens in 6 days due to there being a massive difference in the readings from 2 of the sensors
