Forced Regen by Lexia

[Stickyfinger]

Hi guys

OK...planning a Forced ReGen (via Lexia) of the nasty box in the exhaust as I get a "risk of particular filter blockage" warning and the motorway Italian tune up does not seen to of worked.
I get NO other warnings
So, ?

Is it a good thing to do ?
if so
? What prep work to do ? to make it all safe and effective.

Oil change, Extra cooling fan, fire extinguisher, ear plugs, filter mask, nuke suit, engine grenade resistant shelter ?

IF this does not work, I plan on attacking it with a BIG Drill , whats the best remap service you guys have found ?

Cheers

I think Lexia gives some guidance when you open up the screen... google it though! Make sure you have a decent hard standing (NOT tarmac!) and there is nothing behind the car. Painful to watch by all accounts....

This is on a Mazda, but shouldn't be massively different. Looks like ordinary tarmac hard standing . Doesn't look like much prep goes into the procedure.

\\\\\\hi

\well that does not look too painful


This one however frightens the life out of me !

Common Faults and Operations
There are two common situations whic
h occur with the
Particle Filter.
Both will cause the Particle Filter Warning Lamp to come on or flash indicating that
there is a fault
with the system.
Whenever the Warning Lamp comes on or starts flashing It is advisable to enter the
Additive ECU diagnostic with the Scan Tool and use the Read DTCs function to find
out why the light is on. It is also advis
able to enter the appropriate Engine ECU
diagnostic with the Scan Tool and perform a Read DTCs operation. DTCs are usually
stored on both the Additive ECU and the E
ngine ECU when there is a fault with the
filter. The descriptions of
the DTCs should match.
1.
‘Minimum Level’ DTC: If the DTC disp
layed is a ‘Minimum Level’ DTC this
indicates that the reservoir must be re-filled
or topped up. In this case the Additive
Reset function should be used (see below).
2.
‘Filter Clogged’ or ‘Filter Blocked’ DTC:
If the DTC displayed is a ‘Filter Clogged’
or ‘Filter Blocked’ DTC this indicates that
the filter itself has either reached the
end of its life or is dirty and has not be
en regenerated recently. In this case the
technician should perform the Regenerat
ion function using the Engine ECU
diagnostics on the Scan Tool (see below).
If the Regeneration function is not
successful, or the DTC is still present af
ter a Regeneration, the filter must be
replaced (using the Additive Reset function below).
3.
In the situation where both ‘Minimum Level’ and ‘Filter Blocked or Clogged’ DTCs
are present both the filter
and the Additive should be replaced. The Additive
Reset function should then be carried out (see below).
Regeneration
Regeneration is managed by the EMS system.
Entry to this function must therefore
be done by selecting EMS
and the appropriate system.
The function of Regeneration is to burn pa
rticles which have been caught in the filter
in order to clean it. This is achieved by raising the temperature inside the filter to
around 450°C. An additive is used to reduc
e the natural combus
tion temperature of
the particles to around 450°C.
Under normal driving conditions regenerati
on takes place automatically, every 400 to
500 km (250 to 300 miles). However, some dr
iving conditions, such as urban driving,
are unfavourable to automatic regeneration. In
these cases it is necessary to force a
Regeneration using this function.
The following is recommended practice for forced Regeneration:
1.
The exhaust and its direct environment MUST be clean.
2.
Exhaust gas extraction devices must NO
T be connected to the exhaust pipe.
3.
No-one should go near the exhaust pipe during Regeneration.

4.
The engine must be running and the engine coolant temperature must be above
70°C for a successful regeneration to take place.
5.
The fuel tank must be at least ¼ full.
The Scan tool will guide the technician through the process.
The technician should perform a Clear DTCs function followed by a Read DTCs
function after a Regeneration to check the va
lidity of the process. In some cases the
filter may have been damaged prior to Regen
eration. A ‘Filter Blocked’ or ‘Filter
Clogged’ DTC being present after a Regenerati
on indicates that the filter has reached
the end of its life and must be replaced (use the Additive Reset function below for this
operation).
NOTE: When the technician
is asked to start the engine the Scan tool may reset
depending on the state of vehicle's battery.
If this occurs the engine should be kept
running and the technician should re-sta
rt the Scan tool and re-select the
'Regeneration' option

Best option have it removed.

Best option have it removed.

could be

So...assuming the regen does NOT work. (If it does work no need for now fingers crossed)

1. Fit New ? Cheapest option ?
2. Knock it out and nothing more..? What problems ?
3. knock it out and ECU Remap...Cost ?? Problems ?
4. Knock it out, blank EGR, remap to stage one, Cost ?

Best way

Tips for doing a forced regen are most importantly make sure the oil level is dead on maximum & not overfilled.
Make sure the timing belt is not due for renewal.
This more applies to the DW engines as the filter is underneath but probably a good idea anyway is have the car in high suspension setting make sure not parked on tarmac as it can start melting.
Make sure the exhaust is well clear with nothing (or people) behind it, you sometimes get little hot embers coming out the exhaust.
Just follow all the onscreen prompts & yes it is painfull to watch.

A friend of mine has done his and we are going to do mine.
He did his by removing DPF and CAT.
The way the sensor works is by pressure going into and out of the filter he put a rivet with center removed into, in pipe to increase pressure slightly.
Put all back together working fine with no warnings.
He then filled Eolys tank with diesel.
We plan to do mine by removing DPF sensor from the ECU using Lexia (hopefully) we have to work if we can first if not maybe using another program such as WinOls.

If we suss it out hope to do picture tutorial.

Or you could remove wash with very hot soapy water and then pressure wash before refitting.

When I have done regens on Lexia, it has never worked, in fact the last one I did on a C8 made the pressure differential larger, not sure how
If you have a 1.6 hdi, you need to get it removed correctly, I have much experience with these, and you cannot easily "trick" the car into thinking all is well. Remember the car will still try to regen itself if nothing is changed, so fuel consumption will suffer.
Personally I would get all the DPF removed, blank of the EGR, and change the oil & flush several times. You may just save your turbo before its too late.

Um, the dark side view ...

I understand, mt plan is to remove/blank IF it does not work....

So.anyone know a good but cheap re-mapper in the southwest
