Renault Laguna 1.9 DCi 2006 Dynamique - DPF warning light on #

Posted by Geoff Taylor on May 26, 2012, 2:45 pm

Year of Manufacture *: 2006
Engine Size and Code *: 1.9 DCi

dpf warning light on.
as i am semi retired and help a mate out i would appreciate any up to date help with this subject.after attending the MECHANEX SHOW at event city this week and gathering info it left me only alittle wiser as all the different manufacturers seem to have different aproaches on maintenance and regeneration.

Then the various firms offering solutions chemically so any thoughts and experinces you guys have had on this subject would be helpful.surprisingly on my return a lady turned up the day after the show with the Laguna so is booked in next friday for evaluation on the understanding that I WOULD DO SOME HOMEWORK on the subject.

We have the autodiagnos mt pro but this doesnt have renault dpf regeneration system on it, could anyone tell me if the MODIS or TEXA have this loaded as I may be able to borrow one.sorry if this post is a little unspecific but I feel the more info I gather before proceeding is wise.

Thanks in anticipaction GEOFF TAYLOR.

I have Texa but find it difficult to actually know what it can or can't do without plugging into the car.

Application lists arent' the best either but i will say Texa is fairly good on Renault but if it can do this taks i couldn't say.

Probably best to ask Texa UK if it can if they know or will tell you because its often difficult to find out any info if your not paying for subscription.

Snap-on scan line would also be the best option for tech info on what the MODSI will do but make sure you have the software version to hand before ringing them.

Geoff.

Two different EDC 15 systems, and one EDC 16 available on these and lots of variations of each systems, so i don,t think you will know untill you try.

Do you know any-one with Clip/Alliance ?

Code read first, a good motorway run may get it to do re-gen if that,s the problem.

Be very careful doing a static re-gen (if possible), lots of heat generated.

Check the pressure diff hoses they can become very brittle through heat and become porus esp on this model Seen many split and disintergated, HTH Kevin

One of the problems with these is the 6 speed gearbox. very nice for economy but prevents the engine holding high revs for long on the motorway.

Last one I had I put two Forte Diesel treatments in it, cleared the codes and took it for a high speed (and revs run). Then advised the customer to use a lower gear from time to time to generate heat and bring the DPF into regen mode. (He does a 40 mile motorway commute)

The warning came on once breifly the following week and has been fine since.

progress report
found a post in diagnostic equipment and tools forum dated march 20 2012 from tony attwood which has valuable info in post.with details of treatment with TUNAP products, also before and after readings from screen of what appears to be a bosch kts?.
particulate filter soot impact
particulate filter differ pressure
exhaust gas volumetric flow
all these decrease after treatment.
I have managed to borrow a texa axone which is saying in applications menu that dpf regen is possible on the 1.9dci laguna,so am hoping this will be able to display same readings .then can decide what next best action to take after checking DTCs and visible detections etc,will report back after this friday hopefully

I had one of these in last week and it was the pressure sensor pipes had fallen to bits. Couldnt see it until the dpf was off though. Next time I will be clamping them off and testing with mittyvac :-)

well got car in yesterday only to discover it wasnt the DPF warning light on but the Mil light and spanner symbol light. so checked for fault codes in eobd P2002 DPF efficiency below threshold bank 1.
at this stage raised vehicle inspected the pipes as suggested by kevin and discovered one leading from front l/h side of dpf to sensor on a bracket in eng bay was split.so rang renault dealer for price and was horrified to be told £172 plus vat as it is supplied complete with sensor,so proceeded to cut off split section and spliced in new section of hose. then erased fault code told owner to try over next few weeks and report back hopefully fixed.
