Chaps the CR170 engine management light popped on a couple of weeks back, turns out an exhaust pressure sensor had went south (had this before at 9K) but my local garage also required to do a particulate particle regeneration. Car milage is currently at 19K. Made me think what milage the DPF issues start with the CR170 engine. Still love my 09 LE, but I'd consider that very low milage for a DPF issue to appear. Anyone else with a lower milage?

hi also have a le octavia vrs my sensor went at 22k & i also had forced regen in london gateway carpark . done another 20k since then & no probs with dpf at all .most of my milage is motorway so gets a good blast every month to keep it clean. love mine too

The very fact you are doing low mileage means you are more likely to suffer DPF issues.

How long did you drive the car with the EML on?

If the exhaust pressure sensor wasn't working then the DPF won't have been able to regen. This then allows the soot to build up in the DPF and the car can't do anything about it.

Normally after the sensor has been replaced the car will regen naturally as soon as it can. The fact you've had to have a forced regen suggests that the DPF was close to full.

As long as you haven't had the DPF warning light on then you'll have nothing to worry about.

1 week with light on till I could get it in garage. I've always read on here it is the type of driving you do that causes the DPF issues, ie town driving rather than low milage silver. I do a mixed variety of driving with the VRS town and 50-70 mph every day.

It's strange considering that the VW DPFs do a regen every 400-700 miles anyway, regardless of soot content.

That's right, usually low mileage means short journeys.

Motorway driving is bad for DPF's too. 70mph at 2,000RPM isn't enough either - so Skoda tell me.

I commute 130 mile a day which is a mix of fast A roads and dual carriageways and still have had DPF issues in the past.

Mines a PD though, your CR is much better at getting heat into the DPF but more importantly keeping it there.

As I said if you haven't yet seen the DPF light then you have nothing to worry about, your car is clearing it's DPF just fine.

I drive on the motorway every day, at 70mph. It seems enough to keep mine clear, my soot content is always minute, and that's only because I have a bunch of country road and town driving after I get off the motorway.

I remember reading that the regenerations are more frequent once the mileage goes above 30k.

That's because they get clogged more easily as ash content builds up.

The advantages of the CR system.

I have now covered 63,000 miles from new in my CR vRS and I had only ever noticed it doing a regen 3 or 4 times during all those miles. The light had never come on either until about a month ago, when it stayed on and eventually went into limp mode. Turned out to be a faulty sensor - half a day at the dealer's and it's back to normal. I do mostly motorway driving though so would not expect any real DPF issues.

22k roughly on a 2009 '59' and never had an issue (so far)

Vrs ltd ed 09 exhaust sensor 2 months ago now a DPF sensor and a regen required not impressed at all. 33k on the clock

And the drivers will be completely unaware unless they try to stop the car halfway through.

 

I can plug VCDS into mine and it'll tell me when the last regen was.  But I've never been able to pick one when driving.  I was on an A4 once, flat road cruising and you could watch the fuel consumption pick up, then taper back down again when it was finished.  But I've yet to spot that on the Skoda.
