Hey, long story short.

Car: 2008 PD170 vRS (BMN)

 

I'm getting the DPF/EGR gutted/blanked as I do very little miles and to perform some preventative maintenance. Not in the market for a petrol just yet. Have a few questions.

 

There's nobody local to me that can do all under one roof. So, ill be getting my local mechanic to do the physical aspect -The removal.

 

Unfortunately, the tuner/remapper is over an hour away from my mechanic. The question is, will the car be OK to drive with everything removed and won't go into limp mode or am I stuck between a rock and hard place? I'm not sure of the symptoms of limp mode but from the stories I heard l'd never make it there if that results. Hopefully someone on here has had something similar or knows the best way to approach my problem!

 

Thanks for any help, it'll be greatly appreciated!

Get a mobile remapper to come to you or take the car to someone that can do all the work?

Id say I'm fine anyways. Looked into the configuration of the DPF and the differential pressure sensor will be the only thing affected so that'll cause the EML to come on as it'll notice a low pressure warning due to the lack of a filter but won't affect the power etc. But thanks anyways! 

That aside if the EGR is blocked it will generate a fault code and/or go into the limited operating strategy because the readings from the mass airflow sensor will not reduce as expected when EGR is commanded by the ECU.

 

That is the reason for the existence of EGR emulator/simulators, they fiddle with the output of the MAF when EGR is commanded thus telling the ECU what it wants to hear rather than the truth.

 

When I fitted an EGR blanking plate to my MK2 Octavia I had to drill a hole in the centre of it to stop the engine going into limp mode, I gradually went up one drill size at a time until it did not happen under all RPM/Throttle opening conditions.

 

Maybe you could have a blanking plate with a hole for the journey to the remapper and a plain one for afterwards?

 

Can't advise on the DPF monitoring sensors, mine was pre DPF.

 

I totally understand why you are doing this!

I understand. Was chatting to a few other members who removed their DPFs and blocked the egr but only got an EML and one never even got them remapped after it. The code was for the EGR as you say but no limp mode.

 

Where I live theres very little tuners or good mechanics hence the awkwardness in my situation! I'll be grand once its removed/deleted itll be remapped right away. Thanks for the explanation!

I editted my posting at the time yours was written, read it again as there is more in it now.

Ah see it now thanks! My mechanic says he can retain the EGR without having to put in any delete pipes. Dont know how exactly he's doing it but I must contact him about this. The mate I had done it and deleted it but never had any issues but I suppose like you done itll be trial and error!

 

The main reason I'm doing it is as the car doesn't do as many miles but I'm not willing to buy petrol just yet to see how things are going to go with the climate of electric/hybrid vehicles so definitely not going throw 20k/30k at a car and a new regulation comes in destroying the value of it! Plus love diesel torque for lugging large bulk around!

Damn seen the issues you had there on another thread. Thats the reason I'd never get an all in one or a mobile mapper to do the work. My mechanic has done loads of dpf removals and egr deletes and has never had any issues. The typical all in one that does remapping and dpf removal will be doing it on a cost basis-- by which i mean the quicker its done the quicker another customer is in the door.

 

I've also seen the mobile 'Laptop Kids' come out in transits claiming to do this and that and I've seen the results first hand on my mates cars. I do diagnostics myself and coding on VAG cars just not remapping as of yet! Had a mate with a PD105 Jetta that was supposed to be 145bhp mapped and that thing was way over 170bhp atleast! Would sway and burn rubber in 3rd! Saying that she started sh*ting bricks not long after that map (Turbo, injectors etc) and were talking about a bullet proof 06 1.9 TDi engine! Just thought I'd give some input as I read you owned a nice WRX too! But definitely the BMN should pass the smoke/emissions test as its within the Euro 4 which ran until mid 2009 where DPFs were not mandatory. DPFs are mandatory in all vehicles 2009 and upwards under Euro 5.
