Hi All,
Im a newbie here looking for a bot of advice please.
Ive had a diesel PX1 for 6 years and it's done 110, 000kms and it's hardly missed a beat until this week... Black smoke pouring out of the exhaust under load which is noticeable more with a hot engine.
it had a new EGR last year.
The engine idles perfect with no missfires and I can still hear the turbo whistle when it should with no abnormal noises anywhere.​ Is it worth trying cleaner additives?
The Air filter seems fine and I've tried running without it for a test with no change.
My son has just started driving and he may have driven it a bit harder than me!
Any ideas please before I part with $1000's here in NZ for a mechanic.
Thanks
Steve.
