Alternative to Pump Duse 2.0 TDi

[HiTorque]

I just wonder if there is a diesel engine more reliable and cost less to maintain than PD 2L. I was reading that new CR is more efficient and running with less compression but having DPF made it even less attractive than PD. Has anyone got any experience with Peugeot/BMW or Hyundai diesels? Do they suffer from soot in EGR system at the same rate as VW?
My car is 6 y.o. and I started thinking towards newer one but don't really want another VW.

The newer the diesel, the more EGR involved to meet the emissions of the day. The further back you go, the less pollution control, but so too the less power and economy. If you're happy with a gutless tractor, you can indeed avoid a sooty intake tract.

I'm afraid year for year they all suffer the same soot and buildup issues, and to be honest VW is doing a WHOLE lot better than the Jappers and euro Fords. If you don't want a VW I'd suggest a Beemer, but the pricetag is obviously a factor, and it's going to be eating it's own soot just like a dub!

It's a common downside to all modern diesels.

Is your golf unreliable?

I kind of get where your coming from (ok maybe not really) but unless your golf has had a lot of problems, I don't know how any new car would be cheaper, even if you could get one that didnt have any emissions related problems.

What I mean is - isnt your 6 year old car still cheaper than a new car? I've recently battled my own concience on the matter of a new car, as I'm at the stage where I can afford one - but when my mk3 is still comfortable, performs reasonably well and doesnt leave me stranded on the side of the road, even if I had to spend $4k a year doing repairs (which I don't) its still cheaper than owning a new vehicle, of any sort.

Well, I can change my car and I didn't usually keep japs cars for more than six years, but six years ago I hoped VW diesel could last three times longer . without much hassle. I can fix some stuff and do basic service, but I found it takes now too much time and to some extent money as well. As far as reliability is concerned I don't think Golf mkV was bad, but wasn't good either. I might end up keeping the car longer but my OP was about other manufacturers newer diesel technology, so pls anyone tell me that. I have friends with Nissan Patrol diesel and old Merc 240D that travelled 300K+ and never heard about EGR/soot/ other BS issues we have. I talked to pugs guys and Peugeot 308 HDi has DPF with just different name - FAP, but from pugs local forum could not find anyone fitting Provent into one.

- because people don't know about the Provent - and once they do it's a no brainer - look at the actual Nissan Patrol 4x4 forum, once one guy got onto it, they all followed, but it's one of the few other forums I've found have discovered Provent, and the sheer need for it. It's a common problem, I guess Pug doesn't have many tinkerer's? I've had lengthy discussions with Mann and Hummel who make Provent about the issue, and they have let me know it's a very common problem, and they are keen to try and get Provent out there, but have no real marketing dept to do so. From those discussions I found out that Ford, Mazda and Toyota were all having major soot issues, and they had been onto Mann and Hummel about it. I guess you're lucky to be aware, most new diesel owners have no idea what their pride and joy is choking itself on, and service centres across the country deal with sludge every day on their diesels.

- a 240D had to meet FAR less strict emissions, so doubt it even had EGR, it just pumped ALL it's crap out the tailpipe! ahh the good ol' days !

- The less complex the engine, the less moving parts in the intake, and the less sludge buildup will affect it. Bigger capacity engines too have bigger airways, and again are less affected by narrowing due to buildup. I would expect a 3.0 L plus diesel to be less affected than a high tech, high power 2.0. Remember 320nm is good for a 6 cylinder!

- The Pug DPF has catalyst added, so it regenerates an entirely different way. It will still eventually block, and has the added cost of catalyst whereas at least the SiC ones VW uses are free to run while they work!

Can't comment on other brand diesels beyond that, but I expect there to be quite an issue in the next few years dealing with all these common problems as they start cropping up across the board.

Dads 240D has no emission control at all (same era as mk1 golf). Dads old 240D is also still running just dandy after more than 500,000km and never been opened up.

My opinion of diesels at the moment is that if you want one to keep for a long time, you should buy one thats about 15 years old. All the manufacturers have to comply with the same regulations, and althoug they are all dealing with it in slightly different ways, its all much of a muchness. EGR has been a problem with diesels since the mid nineties, and the next big problem is certainly the DPF.

But if I was in your situation, I reckon I'd persist with your mk5. No-one could argue that its a bad car in any way I don't think. :shrug:

[HiTorque]

Yep, I have to agree with you and I don't have DPF

MultiAir inlet valve actuation will solve the EGR issue since it can be achieved with valve overlap. Since Fiat also developed the CR technology, we really should be thankful to their engineering department.

And hopefully, better DPF designs will developed to help make the diesel as reliable as it used to be.
