VAG 1.9pd engine- what year DPF introduced and which to get?

[tomwoodis]

As per title, I mostly do short runs to work but every now and again do a long run to parents in law and would like the benefit of diesel economy when I do so. Knowing about the issues with DMFs/DPFs or whatever they are called and the fact that short journeys aren't really good for cars fitted with one, I was wondering if someone can tell me what year they started being added to the 1.9pd engine?

I'd be keen to try and get hold of a golf or passat that predates this if I can.

Also, I'm sure its been asked before but which one is the one to go for, 115, 130 etc?

Cheers in advance,

Tom

I have a 56 plate (2007) Golf with the 1.9PD engine. No DPF on mine. It is only the 105bhp engine but has plenty of go to keep up with traffic. Not rocket fast but adequate. I got 530 miles last tank averaging a real world 53mpg.

Interesting, didn't know you could get one that new and dodge the DPF, that's good to know. I presume that means that all of the 2.0 tdi's you see of the same era do have the DPF?

DMF and DPF are 2 totally different things.

DMF is Dual Mass Flywheel and DPF is Diesel Particle Filter. The latter is the one that blocks up with frequent short journeys. The former can be problematic but you will have difficulty avoiding them as most model diesels and some petrol cars have them

I would imagine so but don't quote me on it. I just phoned up the local VW parts department, and asked nicely with the reg number.

Sorry your quite right, I'm being stupid, Its the DPF I'm trying to avoid

AFAIK the 1.9 never had a DPF fitted as it was being phased out when the emissions carp was starting.

I think the 2.0Tdi 140 engine did not have a DPF until it switched from PD to Common Rail injection. The 170 had it from the start.

As an aside, if they journeys are only ever short they may not see an economical advantage from the diesel, DPF or not.

I had a Leon FR 170 with a DPF and did not have any major problems but it was ran on the motorway for the most part.

Just get yourself a decent petrol car and forget these stupid diesels. I bought a 1.9 diesel Vauxhall Signum in April last year, in 8 months of ownership I spent £4k in repairs. The diesel particle filter was the 1st thing to go. But so many other things also went wrong, it spent more time in the garage than on the road. the Dual Mass Flywheel was also on the way out, so it had to go. For short runs, forget diesels, they aren't worth it, just too much hassle. Never again for me.

I have the 140ps 2.0TDi PD in a late 2006 Octavia, and mine does not have a DPF.

Sounds like I might have the facts right for once then!

Think th op is exaggerating the dpf issue . Some diesel fords have dmf issues while vag had the injectors go on some 2005-2007 cars, all that fixed or refunded by dealers and it seems newer cars dont have same problems as their predecessors

Dpf is a non issue

Boring techncal bit. Because of the different ways the PD and CR engines step up the fuel pressure, a PD engine is not well suited to supplying the extra fuel required for the DPF regeneration cycle. What ever you think about DPFs in common rail cars, the cludges required to make then work in PD cars probably expains why most PD engines don't have a DPF.

I know common rails engines are cheaper to build and offer better emission controls for the future, but I'm more than happy to keep my simpler PD engine for years to come. The VAG injector issue was due to injectors manufactured by one supplier, and was pretty much limited to the 170ps engines and some 140ps Passats.

i have just bought a 1.9 2005 golf tdi ..its a bit noisey on idle ..does this relate to any known problems with this mark ?

No petrol cars have DPF, you are normally spot on, having a bad morning?

Lol

Lets not get things muddy here , you would have spent the same amount on petrol vauxhal . Next time don't buy bottom of the pile and expect trouble free motoring . Please go away now cuz you told everyone how a sty signum keeps breaking down therefor all diesel are crap

Not quite right, my 2008 Octavia Scout 2.0 TDI PD had a DPF. I think they fitted them to all 2.0 TDi cars from some time in 2007. The models changed from PD to CR over about a 12 month period, VRS went first, Scout last.

No he isn't - he said former (Flywheel) and is correct.

Never good on a Monday morning but please read the sentence again, I never said petrol cars had DPFs. When I refer to diesel and petrol, I'm talking about DMFs

Don't know about the 1.9 lump, but the 2.0l 103kW diesels had DPF as an option from 2006, and non-option in 2007. One thing you could look at is the motor ident. number. BKD is 16v without DPF, BMM is 8v with DPF. I was told that the 16v engine isn't suitable for use with a DPF, so the DPF is only fitted to the 8v version, and of course the CR's, with motor ident CBAB

Depends on whether it is a PD or Common Rail as explained in detail by a poster above. A fair few PD cars have had issues as the tech was patched on as a temporary fix, whereas it was designed in to the revised common rail engine.

AS with any known problem for a particular car or engine, it is never going to affect every car.
