How to tell DPF from normal

[mattbeef]

Afternoon people

Just a quick one for you all. How can you tell the DPF TDI from the normal TDI in the Leon FR?

Mum has just put a deposit down for one and my old man was asking. Im guessing it will be via the engine code like all other VAGs

I believe on the 170ps/hp TDI has the DPF in it. the 140hp does not.

 

[mattbeef]

Sorry maybe i should have made it clearer.

With the bonnet open how can you tell which engine your looking at?

 

[DanGB]

Not sure but the 170hp is only in the FR and the 140hp is in the sport, ref sport and stylance.

Yep, exactly.

Only the TDI FR has the 170Bhp engine in it, and this is the only one with the DPF, all other 2.0 TDI's are 140Bhp non-DPF engines.

Ahh thanks for that guys looks like the dealer was talkin from the wrong end then as he was saying that it can come with either engine

the 140bhp 2.0 tdi is now listed as having a dpf aswell on the seat site

Just as an aside and a bit off topic but there was a brief article in Whatcar? this month saying that the RAC had done some work looking into DPF's in cars and they concluded that you need to be doing at least one 50 mile motorway run a week to keep your DPF clear and stop it blocking up.

If you don't this will cause problems with it and reliability can suffer.

Thats worrying becuase I'm doing town driving most of the time. Still, in a 1000 miles I've not had a problem..... maybe my heavy right foot helps!

You sure?
Have you got a link or can you point me to where it is?

Do you know which type of DPF they were talking about though?

There's at least 4 variations of a DPF each have their own unique problems and advantages.

I'll dig out the magazine tonight and have a look. If I remember correctly it just referred to cars with DPF's in general.

I'm not to up on diesel technology, I take it this is a recent feature of modern diesel engines??

From what i can recall:

Renault = Some sort of paper filter changed every 10,000 miles at service.

Skoda = 140Bhp engines have a regeneration additive (a bottle of liquid in the boot) which gets added to the thing to help burn of the particles caught.

VW 170Bhp engines have a self regenerating fuel cell which starts of the generation process without an additive.

Pugeot = had a similar method to Renault - but different - cannot remember now.


There was a really big article on the TDI section about all this - but lost it now (think it might have linked to the skoda forums)

 

[mattbeef]

Thanks for all the advice as mum will be using it to go to work and back so if it needs a good blast ill have to take it out.
What a shame

 

[k4ith]

50 miles? they should come with a warning before you buy them then. I reckom a good blast will help....... or thats what i keep telling myself.

cant find it now on uk site might have been on there main site will look again

Right got it and a few clarification of the facts but message is broadly the same. This is word for word what it says - as I say, not a big article:

Drivers who buy diesel cars with particulate filters to trap soot from their exhausts gases run the risk of reliability problems if they cover only short journeys. Fleet operator Lex has warned its customers that such cars need to do 50 miles at motorway speeds every couple of weeks to avoid clogging up the fileter.

Also here's the link to the full article on the lex leasing site:

Hope this helps

The Superb uses the additive but that is a 140 bhp 2.0 8V PD engine, that system is not used in any other vehicle (good job as well).

The VW's now have a 140 DPF and 170 DPF as do Skoda so i wouldnt be suprised if SEAT did the same.

 

[Michael B]

Does the DPF have any negative effect on performance - I won't be putting a through pipe on, but is it possible to do this with out ****ing up the ECU?

Also, what about red diesel, probably wouldn't be good on the DPF?

 

[chippenhamwilts]

Red diesel (tax free) is only a dye additive, as far as i am aware there are no real performance differences to taxed diesel.
