Help! I was sold a car not suitable for the type of journey I do

Doesn't matter - it could equally be hollow from collapsing internally and blowing its contents out the back. As far as the test is concerned it's still visually present.

You keep repeating it all you want, doesn't make you correct.

Seen many DPFs that have "collapsed" internally blowing their "contents" out the back?

Have you actually seen what a DPF looks like?

I assume you are happy to indemnify any forum member that takes you at your word?

a dpf software emulator is better than sending the chimmley sweep up the dpf i would have thought
its quite common to cut out the extra injector on the ad blue with an ali extra
ps if you dont understand all this jargon then dont worry

A DPF emulator simply fools the ECU into thinking the DPF is still there. They were used by some on the 2.7 diesel engine in the S Type, probably used in the XF and XJ with the same engine but to be honest they were never particularly good.

And since AdBlue is usually only fitted to the very latest Euro6 engines it isn't that relevant to an oldish Golf.

once your car is hot you can force a regen by siting in neutral in a quiet car park and revving the engine to a steady 3000rpm (or whatever it requires). When it regenerates you will know because of the clouds of foul black smoke coming out the back. Some models actually recognise what your doing and the engine management takes control, you can floor the throttle and the rpm remains exactly at the specified rpm for a regen. It is more effective than trying to complete a regen on crowded roads. Must be worth a try.

I've never heard of that - a forced regen usually has to be initiated by using a diagnostic tool attached to the ECU. Also a normal regen shouldn't cause any smoke. OP - I suggest you give the above advice a sitff ignoring.

I've read somewhere that the new fleet of Fiat Diabolical vans on Royal Mail have been fitted with some kind of system where the driver can initiate and complete a forced regen out on the road, never heard of it being possible in the standard hardly fit for purpose fodder the modern car buying public choose for themselves.

You can buy Dongles that go in the diagnostic socket that do that.

Apparently Carly for BMWs now has that functionality.

Most cars have the functionality to be put into Regen when stationary via diagnostics.

When I did a forced Regen on my Jaguar using Snap On diagnostics I had to take it for a run. It even instructed you to do so.

The Jaguar system (3.0 tdv6 specifically) will not Regen when below a certain speed, I was told that the Land Rover/Range Rover system is the same but when using a clients Range Rover Sport it would Regen at slow speed, would also smoke a fair bit when it did so.

Personally never had a problem with dpfs and rarely use the motorway.
I do fairly high speed runs however, lots of 60mph roads but also plenty of stop starting.

The phrase 'drive it like a petrol' i agree with totally.

Its about knowing under what conditions your car will regen and keeping an eye on the oil level if you are doing plenty of stop start driving. Not very economical (well around 40 average in my mazda5) but its worth dropping a gear regularly. In fact i have hardly ever used 6th gear even on a motorway in mine, its just a dpf light waiting to happen!(unless im doing at least 85 which i never do)

Also im aware of plenty of people who swear by the forte dpf cleaner and regenerator when the dpf light comes on.Try that and change your driving style

Drive it like you nicked it, never fails!

Main lesson from this thread seems to be never by a diesel! Who knew it could be such a pain.. well at least I (and the OP I guess) didn't.

Complete rubbish conclusion - I think that you should go back to post #1 and read this complete thread again.

The lesson that you should get is that people need to choose the correct car for the type of driving they do.

Short journeys - engine never gets really up to full temperature - buy a petrol.

Longer journeys - lots of motorway work - get a diesel.

I have a diesel - it's a trans-continental mileater - for me a petrol engined car would be just plain stupid.

Before buying any car you need to do a bit of research.
