How much do I have to worry about this clogging up?

I have just changed jobs and my mileage will drop from 25k pa to probably less than 10k of short journeys. So I am a little concerned that I'll start to have problems.

Does anyone have any experience of this?

Have you had the emissions so called fix ?

I didn't think the b8 needed it. Does it?

No, it doesn't.

Short journeys will slowly kill your DPF, consider selling it for a petrol car.

Egr causes increased soot for the dpf get rid or both .

What's the minimum type of journey I should make to prevent problems? I could probably take the car out for a bit of a run a weekends.

Once a week, 60mph in 4th gear for 30 mins will suffice.

I'd be selling it and getting a petrol car as you'll pay more for fuel and a cold Diesel engine isn't fuel efficient.

You say that but my 1.9 tdi estate indicates 34 mpg short run to the shops from cold .

The previous car was smaller , lighter with a 1.7 petrol that would adverage overall 30mpg in a labritory !

Try doing that same run in a modern diesel.

You don't realise how heavy the 3G Passat is also and it's sheer size, short runs lugging around weight won't help.

A 3G can be upto 85kg lighter than the equivalent 3C ;)

My current car was purchased 2nd hand with 36k on the clocks. It has now done 76k, 95% of which has been short 10 mile journeys with only 2-3 miles of that on a 50 MPH dual carriage way. Only had 1 DPF issue, which was when the EGR failed and it couldn't regen. Once that was fixed the car was able to do a regen and been fine since. That happened in May last year when the car had circa 65k on the clocks.

In short I wouldn't worry about it too much.
