Thinking of changing my car soon, but a little worried about the dpf on the 1.6 CR tdi, anyone had any problems with it on higher mileage cars, would like the green-line if one becomes available in my budget

I've not heard of any and I read most DPF threads with interest (due to a few niggles with mine on my PD170).

Saying that the 1.6 CR105 TDi is still a relatively new engine so there won't be as many high mileage ones around.

I do remember one DPF thread where a taxi firm had swapped most of their non-DPF equipped 1.9 PD105 TDi Octavia's to the newer 1.6 CR and had no end of DPF issues, enough for most of the drivers to change brand away from Skoda.

I don't think there is anyone who can remove and remap the DPF on a 1.6 yet either?

Maybe the 2.0 PD or CR would be a better buy, you'll just have to live without the gimikey stop/start feature,

I suppose it depends upon the type of driving you'll be doing. If its a lot of stop start driving, like the taxis in Silver1011's example, then you could very well experience problems.

If, on the other hand, you are travelling up and down the motorway then you'll probably be ok. It seems that DPF's become problematic if only driven on short journeys.

I do not have the greenline version, but any model with this engine needs to be pushed sometimes.

No need to go into highway, just push a few gears.( 2º reaches +80km/h, 3ª+130km/h)

If you are going for the best mpg all the time and donnot pass the 2000rpm range, the car can have either 500km or 50000km the filter light may come up.

If it does, then all you need to do drive on the highway above 2500rpm.(don´t have to go in fifth)

When you feel the car is regenerating try not to interrupt.

Mine has 54000km and bem averaging 5 to 6 liters per 100km.

It´s now been reprogramed and passed from 110hp to 140hp.

Look at it this way. The DPF is more likely to clog up if you don't drive the engine hard enough. You are more likely to give the 1.6 a bit of a good blast, more often, than the 2.0. Therefore more likely to clean it out. So its a choice to be made depending on how you see yourself using the motor.

I have got a 2.0 CR 140 and my good friend has a 1.6 CR 105 Greenline but they are both less than a year old. No DPF issues yet.

1.6 TDI/ DSG, 35,000 miles, most weeks multiple short runs.

Longer runs at weekend, mostly a liesurly style of driving but sit at 80 odd on the Motorway.

I do not know the DPF exists.

The DSG software is happy to pootle about at 1500rpm pulling 50mph in 7th gear.

One does NOT require to thrash this engine or hold her in artifically low gears btw, EVEN to clear the DPF if the warning light comes on......as per the Manual.

I would wholeheartdly agree.

My 1.6 CR TDI is just shy of 2.5 yrs old. Currently at 35,200. Daily commute is either 11 miles town or 24 miles 40/50mph. Once or twice a month, there's a motorway trip of 300-500 miles.

Overall I would say 'no issues with the DPF' but in the interest of full disclosure, there was a cold morning last November when the DPF symbol lit up on the way to work, so I detoured up the motorway and back for 25 minutes, nothing harsh, just sat at 60mph. The light went out and hasn't been back since.

I give the engine a blast every now and then - but that's down to my heavy foot rather than any conscious effort to stave off DPF issues. Besides, given the protocol for clearing a partially blocked DPF (i.e. sustained driving above 40mph), I not sure a 'quick blast now and then' would do anything to keep the DPF healthy?

It will be used as a taxi, so can give it some welly every now and then, I wonder if Ben has managed to do a delete on the 1.6 tdi yet??

The DPF on the 1.6 CR is closer to the engine and has a catalyst that keeps it hotter for longer.

In my 2.0 PD I can be sat on the motorway at 80mph and have the DPF light come on. To clear it I have to drop to 4th / 3,000rpm for approx. one mile to clear it.

So on some models it IS neccessary to increase the revs.

All you are trying to do is increase the temperature of the DPF, the quickest and easiest way to do this is to increase the RPM of the engine for long enough for the temperature to rise high enough and the active regen process to complete.

Ok, good information, that puts right my assumption on revs vs. time vs. DPF health. Also explains why mine was easy to fix.

Is the 2.0CR more like the 1.6CR, or the 2.0PD regarding engine/catalyst proximity?

The 2.0CR has the catalyst too, the 2.0PD doesn't.

Only recently reprograming became an option.

Mar car tested from 110-113hp and +/- 270nm (around 200lb/ft) this original

After tuned it came out with 140hp and 320nm (around 235lb/ft)

Now the tuner is working on how to eliminate recirculation system ( EGR), but no delete filter, not yet anyway.
