DPF removal on E250 CDI - UPDATE

[subzero]

After getting in touch with several companies who could not do the DPF delete on my car I came across extreme remap based in Gloucester. I mentioned to the owner Craig that I have tried so many places but no one is able to do a DPF delete. He confirmed that he couldn't do it either but they were working on it, a few weeks later he called me & I booked in an appointment.

1 week after the removal, the car is a lot quicker, although I haven't noticed any improvement in economy. I will look into having an economy remap soon as the standard 204bhp is quick enough for me.

Anyway, I just thought I would let all know, anyone with a Delphi ECU code CRD2.61 - if you are looking for DPF removal & delete Craig at Extreme remap in Gloucester is your man.

Very helpful as cars get on this is an expensive component to replace if it fails and the car needs a Map as it will throw all sorts of errors if the DPF is removed.

BTW, if you soley do fast A/B and Mway driving, will a DPF ever fail if get the chance to regenerate?

 

[subzero]

I am not sure if your style of driving will prompt the regeneration process. Before I had mine removed I went on a 30 mile run at 70-80mph with the rev counter showing around 3000rpm, this wasn't enough to start the regeneration.

I also paid someone £100 to clean & regenerate which they supposedly did but it didn't take long for the engine management light to kick in.

I was shown the filter after it had been removed, it was in pieces but I could clearly see ash falling out, so I'm glad I had it removed & I’m pretty sure nothing could have cured it!

I am being a bit thick here.


But what downsides/implications are there to removing it?

how much did a removal cost?

 

[GAD Tuning LTD]

It benefits the car so much having it removed! Lower EGT's, faster turbo spool, increased performance, increased economy and also DPF's go wrong all the time and are extremely costly to replace.

Once its out it will never go wrong again.

I paid £400 to have mine removed. As far as I know this is the only guy so far who can remap the ECU (DPF Delete) on these models.

 

[GAD Tuning LTD]

No this is not true as we have removed the DPF from these ECU's on many vehicles. Was that £400 for the software? Or was hardware removed also?

Believe me, if you have the problems I have had with a DPF deleted car that I have in at the moment you would either leave it as standard or fix it properly. Yet another DPF deleted car to add to the list on running issues caused by these remaps.

I know this may be unfavorable to some peoples business but this is the 3rd car this year to be suffering from performance issues after a remap.

 

[GAD Tuning LTD]

Steve@Avantgarde you are completely correct! We get a lot of work fixing other tuning companies work! Its a terrible thing really. Some tuning companies will increase fueling to much to the point where DPF blockage is inevitable (also issues with EGR valves clogging)

so steve - you would not recommned someone happily plodding away in a E220 2010 model looking for bit better fuel economy to do something like this?

Not if you want the issues that cannot be identified on star diagnosis to take a while to be fixed and at a cost that is likely to outweigh any future savings on economy!! Ive got one here at the moment stuck in limp mode generating no fault codes as the trigger points for fault codes have been infinately mapped. The software they have also installed has corrupted the EIS switch so I cant even reflash it back to factory settings.

So to even obtain a fault code I need a new EIS and green key at around £450, I have wasted around 8 hours trying to manually diagnose it with scopes etc and all in all for a gain of 4-6mpg and about 20bhp.

So in my humble and technical opinion, its a complete waste of time and money. Unless of course you have some one like GAD close by who appear to know what they are doing!!

Another question I would raise is, if you arent a high mileage user, why buy a diesel? Surely the cost of fuel vs economy debate would rule in favour of petrol variant?

 

[GAD Tuning LTD]

Why thank you Steve@Avantgarde!

It sounds like to us that a patch has been applied which will disable fault codes and EML. It also sounds like they have "protected" the file so that it cant be re-flashed.

It appears to be no one removing the DPF structure or performing a regen before removal as so to reset the ash counter.

i do a fair bit of miles - 18-20K a year, by plodding means i don't drive it sportily, it is an estate and my wife thinks it is a old grandads car.........so i probably drive like miss daisy to suit the car!!!

thanks for the impartial advice. i might leave it out for now

 

[Steve@Avantgarde]

This is a weird one Gary, it had no DPF in it, all the sensors were cable tied out the way. Its in limp but has no engine management light on and the 30 day exhaust filter service light is on. If you disconnect any of the reliant sensors the ECU still usually uses like the DPF pressure sensor or the MAF it records no fault code. Randomly it will come out of limp and the exhaust filter light will go off and it goes fine and then when it limps again you may get a fault code for MAF sensor signal too small. The MAF is new by the way which was fitted by the customer.

I have fitted a replacement DPF and attempted a reflash as usually this works and you can then generate a fault code in which to fix the issue but the EIS has been corrupted, the print out from star says to replace component EIS before reflashing. I have cross referenced this and a mate of mine who works at main dealer has had this issue before as well and he had to go down the route of a new EIS and then all was ok.

Whoever has done it has done a terrible job, all the exhaust fixings were loose or missing, they have obviously done an exhaust manifold gasket as none of original studs are fitted just normal M8 13mm bolts which aren't even high tensile. I would love to name and shame these monkeys.

I have to be honest and I know this will fly in the face of what you do for a living but I'm not much of a fan of shunting and modding, I prefer to fix whatever is there properly and keep it as it should be.

Not unless a good company can change my mind.....???!!!

I understand. Plodding a car with a DPF is fine, if you use it for more than 20mins on a journey it should regenerate enough not to cause you any issues. In fact many of the issues we get on DPFs on MB's tend to be where the CAT breaks up first and damages the DPF, its not the DPF that causes the issue!

£400 was for the removal of the DPF from the vehicle, DPF delete from ECU & smoke correction. I have been drving the car for around 3 weeks now, performance is better, economy is better & the engine managament light has never showed since.

I did try you guys but it was confirmed that the ECU on these cars cannot be done & the only option was a emulator.

I'm only sharing my experiences with people so anyone who is in my past situation with a E250cdi ECU Delphi CRD2.61 now knows where they can get their DPF issues sorted.

 

[T5R+]

My E250CDi 2010 60K just out of warranty has kicked out three codes

• crank shaft sensor
• exhaust temperature sensor
• dpf blocked

Not impressed with MB who "may need it for a day to full diagnostics" :lol:

If I end up down the delete dpf route......is there anyone based in/around Manchester/Leeds/M62 that is "nearly as good" as some of posters on here. Thanks

 

[GAD Tuning LTD]

Morning,

I would highly recommend Eliteremaps based in Leeds! He really knows his stuff and never uses any form of patching he always removes properly.

Anthony

 

[GAD Tuning LTD]

Or of course you could always pop down to us!

Probably the temperature sensor is fault. Did one on a C250 the other day and I believe this is getting a common issue, MB have sold quite a few in the last 6 months when I checked.. The sensor is £71 and takes about 20 mins to fit.
