DPF Troubles - break, sell or fix?

You can get the DPF removed and bypassed completely. Its about £600 notes and apparently you get more power and better mpg and no more problems.

On the peugeot 407 its about £100.

All you do it remove the old one take it to a local metal fabrications place who cuts it open and removes the guts then welds it back up again. IIRC you then just short out the sensor

Or do it yourself if you can.

Out of interest is the diesel mazda 6 particularly bad for dpf issues? My brother in law has one and is having this problem

Yea, they are a pain in the back side. To top it off, the design of the thing means that if the car attempts a regen in the right conditions and it fails, the unburnt fuel is dumped into the fking oil sump!

This means its not long from a failed regen to an oil change. I had half a dozen oil changes along with dpf troubleshooting before I finally gave up and through the sack of st on eBay. Bought for 3550, kept 6 months and sold with dpf light flashing for 2000.

At one point I was manually clearing fault codes whilst on the move to try and clear the fking thing out.

Biggest car mistake I ever made and will never have another piece of that wky bks engineering again.

I hope to hell the tech gets better before my PD octavia is no longer usable.

Your Octavia should run and run. If it's a PD130 or early 105. Rough old engines but bulletproof IF properly serviced as per the Teutonic mindset.

Yep, its the PD130. It's my second octavia, only upset by the interlude of the bloody Mazda. the first one I took from 77k to 176k and it was still as tight as ever. Sadly I wrote it off. this one is showing no signs of slowing yet

I stand to be corrected, but I think its a shared engine but individual exhaust/ dpf system. Mazda's was ste, ford learnt from their mistake and made it less ste

they just fked everything else up.
