BS6 Isuzu D-Max EGR issues: Had to be cleaned 7 times in a year!

We are advised to go for long fast cruises but in a mountainous region with winding roads and a 50 km/h speed limit, it is both illegal and dangerous.

BHPian country_road recently shared this with other enthusiasts.

Hoping to get some advice on how to handle a recurring EGR problem.

My BS6 D-Max S-Cab has clocked around 15,500 km (in a little more than a year since I purchased it) but in that time, my EGR has required cleaning (following a check engine light and scanning) at least 7 times! And the EGR valve has even been replaced thrice in addition! So at least 10 trips to the service centre here in Thimphu. And at almost every one of these trips I've met others who require frequent, but not as mine, EGR cleanings. However, it has been done at no charge to me which is appreciated, although obviously, the hours I've lost at the workshop have been adding up with each visit averaging 3-4 hours.

For a long time here, BS6 owners and mechanics have and continue to remain confused and frustrated at the lack of a long-term solution.

Isuzu India has apparently done some research on the issue, according to Isuzu Bhutan, and claimed albeit not publicly, or informed us owners, that the culprit could be diesel with higher sulphur content. As far as I know, the fuel at the pumps here is already BS6.

Occasionally, we're also advised to drive at higher RPMs and go for long fast cruises but in a mountainous country with winding roads and a 50km speed limit, this is both illegal and suicide.

My question is if any fellow Isuzu owners in India are facing the same problem and how you might be handling it. Or if anyone with knowledge on the issue could please advise.

My thanks in advance.

Here's what BHPian SH1N1G4MI had to say about the matter:

So, this is going to be quite the controversial opinion but see a tuner and get an EGR delete. Can't have EGR issues if it's turned off. It's a feasible solution and will keep the engine healthier in the long term.

Here's what BHPian country_road replied:

Yes, the mechanics here did tell me that blanking or installation of an EGR delete kit would make me fail the emissions test. But it is starting to sound like a viable option compared to having to visit the workshop every 1,000km or so for a time-consuming cleaning.
