Yes it is definitely a weakness on these 2.2 hondas and it's a pain in the backside sometimes a clean and reset will still only last a couple months

A thing to check is that you don't have the oil too full, a level halfway between the dipstick min and max marks on level ground is the limit. For some reason this affects the DPF regeneration, forced regens are fairly stressful for the engine and exhaust so if you can avoid them it is a good thing. I'd suggest getting an OBD tool that can monitor the differential DPF pressure, if that starts to increase then you can try adding some DPF cleaner and then go for a half hour drive at 2,000 rpm or so on a decent dual carriageway. However, sometimes there is no substitute for Jimmy and his Launch Tech gun and fluid. My 264,000 mile Accord 8th gen iDTEC has just had this treatment and it's back to great performance again. Worth the money certainly.

@@BrianMorrison Hi Brian, thanks for that. At this point I've tried almost everything I can think of, including frequent oil changes with recommended 0w30 ACEA C2... Even the dealership are at a loss beyond replacing the DPF. I've got a scanner but it is fairly limited even with live data, showing no fault codes and low pressure with low particulate matter. Just an absolute nightmare of a car. At least it has heated seats though! 🤦

@@mingtooter My backside stays cold I'm afraid. If you can get it to Jimmy then you may find things get better.

Cheers

He drove around 60 miles to me 😬

Wouldn't say the scan tools are useless but no matter what tech you have it all comes down to experience at the end of the day 👍🏻

Most vehicles now calculate ash and catalyst /DPF age & miles and will just chuck a code saying it needs to be replaced. Luckily like I show here it's rarely ever true 👍🏻
