Hi there folks,
Im finding that my 1.7 DTi astra estate with the Izuzu engine is beginning to get quite smokey. I have 155,000 on the clock and use it as a taxi but have had no previous problems with anything on the car or engine except for normal wear and tear.
The car is service every 15000 with a full service kit and was just service 2 weeks ago but this has made very little difference. Used a can or redex first but difference was questionable now used a can or forte and still no joy in smoke reduction. I suspect it may just be the mileage on the engine kicking in but im unsure. Engine runs very well with good acceleration and smooth operation but taxi test is due soon and im unsure if it will pass a smoke test as it is.
May just be paranoid but just checking to see if anyone has any ideas incase i could clean anything etc for example the injectors or whatever. was also thinking it may be a ecu timing abnormality so i was gonna disconnect the battery to reset the ecu back to default injection timings also no fault codes from the ecu either.
Any help would be great.
