My D Max keeps going into regen, short trips mainly, but can do it twice in an 8 mile trip, it’s 67 plate done just over 30000 miles, any ideas, dealer can’t see it till the end of next week.

It’s not done it before when I’ve done short runs, took it for a 30 minute blow out, thought it was sorted but doing it again now.

First thing check your oil level regulary, frequent regens can raise your oil level very fast.
second I would recommend asking an isuzu main dealer to run diagnostics, a good dealer shouldn’t charge it doesn’t take long.
Over fueling injectors are a common problem and this will block the dpf and then cause frequent regens which makes matters worse.
Mine needed 2 new injectors because they was overfueling and Iv pulled it back from 30ml regens to 100-110mls.
People normally recommend dpf and egr delete programs but this still won’t cure overfueling injectors.
It could be a faulty £100 dpf sensor or the £400 sensor also apparently.

Took the truck back to the dealer yesterday.
They changed the oil, as there was too much in the truck.
Found the turbo wasn’t boosting, so repaired the vacuum line (blocked/kinked).
Forced a slow regen
Removed and checked egr.
Charged £226.67 plus vat.

Picked it up, drove 10 minutes and regen light was back on, came on 4 times in the hour and 20 minutes drive home, taking it back today.

Have they checked the injectors do you know?

Just out of interest how much were the new injectors?

They are saying injectors are fine?
not sure how they test them more than off the laptop?
That’s how they test them. Mine were only a little out of tolerance but they checked them a few times over a number of weeks and then decided they were out enough to make a difference.

Apparently mine are in tolerance.
Saying they thinks it’s the dpf itself

Whats the ash content of the dpf at?

A dpf is just a filter. It doesn't not 'work' - your issue is :

a) the engine is producing way too much soot so plugging up the dpf sooner than it should.

Or b) the ecu thinks its plugged up and keeps wanting to regenerate the dpf

Or c) something is preventing the dpf reaching burn off temperature

Bugger, dealers are talking to Isuzu now.
Tbh it’s been good for 9 years but getting very rusty underneath, and getting noisy in 4wd ( gets a hard life) and when my last jap pickup went bang ( Nissan)and had to be wrote off at a fairly young age, I vowed not to keep them as long. Seem to get a money pit at 10 years plus. Previous Isuzu ( trooper) had engine problems so I have decided rightly or wrongly only to buy European from now on so a 2 year vw is on its way. No doubt it will have its issues aswell😂

Written by William Kellett from Agriland

A man has pleaded guilty at Newtownards Magistrates’ Court to waste offences relating to a bonfire next to the electrical sub-station on the Circular Road in Newtownards, Co. Down.

Gareth Gill (51) of Abbot’s Walk, Newtownards pleaded guilty to two charges under the Waste and Contaminated Land (Northern Ireland) Order 1997, for which he was fined £150 each and ordered to pay a £15 offender’s levy

On June 25, 2018, PSNI officers went to Gill’s yard, where they found a large amount of waste consisting of scrap wood, pallets, carpet and underlay.

Discussion with Northern Ireland Environment Agency (NIEA) officers confirmed the site...
