Just curious, like...

[Rustinho]

Has anyone out there in Surfland removed a DPF (diesel particulate filter) from an exhaust system and re-programmed an ECU (using something like Galletto) at all?

Just curious 'cos the sort of cars I'm looking at seem to have problems related to this kinda thing (going into "limp mode" cos the ECU detects a problem).

If anyone has dealt with this kinda thing I'd really appreciate it if you could share your thoughts & experiences so I can walk into this with my eyes fully open to any problems.

I've already done a fair bit of reading around various owners forums but it can be difficult to gauge the relevance of peoples opinions when you aren't so familiar with their regular posts, etc...

Thanks in advance for any contributions, folks.

A DPF is similar to the EGR system on a Surf isn't it?
Depends if the car has a DPF warning light as to whether the ECU will throw a wobbly I guess.

What cars are you looking at?

Mostly Peugeot 406 diesel estates cos there seems to be tons of them around and they look pretty reliable but I'm not ruling anything in or out at the moment.

The DPF is a perforated ceramic insert at the engine end of the exhaust system.

The theory goes that you whip the DPF out, drill through it with a core drill to remove it, disconnect the sensors and then re-program the ECU to get rid of the DPF (and usually while you're at it improve power, torque & fuel economy!)

Reading through a "how-to" guide on the Peugeot owners club forum it looks *fairly* straightforward to do as long as you follow the instructions and have a copy of the right ECU files available but I was interested to know what it might be like in the real world if anyone on here has done anything like that.

Peugeot?!

[Rustinho]

Peugeot?!

Yeah, yeah! I know! lol

I've seen quite a few of them with 350-450,000 miles on the clock so they can't be that bad (apart from maybe slightly dodgy electrics in some cases) and there are loads of 406/407 diesel taxis around here (The three main cars used as taxis here are diesel Pugs, Toyota Avensis and Skodas).

My first car was a 1.6 Peugeot 309 and it was great apart from having a problem with the mechanical fuel pump. There was a seal gone in it somewhere so if it was left for more than a few hours the petrol would drain back into the fuel tank. I lived with this by carrying around a syringe and injecting enough petrol directly into the fuel pump to get the car started cos once it was running it was fine. Used to get me a few odd glances from folks on the car park at work!

Just don't get the HDI engine Pug.

Why?

[BUSHWHACKER]

Why?

They seem to brake down a lot.

Type 'HDI problems' into Google.

diesel+reliability+power+econo my = BMW 330D 184+bhp 42mpg just dont show it snow or ice!! I had one for 4 years and loved it for 10 months out of 12, cursed it for the other 2

Someone has to fight the pug's corner I suppose, it may as well be me

I have an X reg 406 2.0 HDi estate, had it for 2 years and 40000 miles so far and in honesty it's been brilliant, huge boot space with the back seats down, drives at least as well as any modern car, high 40's mpg on average, 50+ mpg on a run. All it's needed in the last 2 years other than servicing is a front coil spring and a set of tyres.

Mine had been well looked after when I got it, it has just over 130k on the clock now and I can't see why it wouldn't do that again. They don't all have a DPF (mine hasn't) so just look for a good one without.

Hope that helps

Interesting. There will always be nightmare stories (just like Surf cracked heads) and thats what people will tend to write about.

However, almost none of the results on the first few pages are anything to do with 406s with the 2.0 HDI engine. Maybe they're the best bet for them or the sort of folks that drive them look after them a wee bit better...?

I'd already read about problems with the smaller (& bigger) HDI engines.

I'm still undecided though. It's just a matter of dropping in on the right car at the right price.

We see a few peugeot hdi diesels come throw my work . The only major problems I have seen are front coil springs failing ,injector seals leaking and if you buy one with a dpf filter check the service history to make sure it has been serviced with good quality low ash engine on normal oil will cause the dpf to block . Hope this helps

For what it's worth, if you're looking for economy, some of the older pugs are very tolerant of high concentrations of veg oil. If memory serves its the 405s that are favoured but I could be wrong.

If its of interest to you have a gander at the vegetableoildiesel forum. I think some over there discuss the mod you mention too.

As long as it was a Bosch pump, The lucas pump won't tolerate veg oil but it will be ok with bio diesel, I've had a few 1.9 XUD engined cars apart from head gaskets failing at around 95,000mls The engine has been well proven, The HDI does have a tendency to put number two conrod through the engine casing if you drive it hard normal use it should be fine, The HDI is also not too tolerant of vegoil either from what i've been led to believe.

I once had a 406, The brakes were fine.
