What do you think could be the problem?
Its so strange how blanking my EGR has had the complete opposite effect to what 99.9% of people experience.
Could it be my injectors out of sync or something along them lines and if so, how do I find that out?
Should I remove the blank and have the DPF removed and ecu remap but NOT remove the EGR software?
Glad (in a friendly way) that yours also sounds like a tractor in this weather! LOL
Couldn't tell you tbh, and not sure what I'd do regarding the EGR blanking either.
It just seems to me that it clogs way too quickly, even if you're only doing short journeys.
Regarding the other comments about smoke, surely the fact that you've no smoke could be a result of the DPF catching it all, and clogging?
If anyone knows more about this than I do then it'd be good to hear. Touch wood I'm still OK with mine, but one day I may need some of this advice myself!
The turbo on mine seems a little more whistly in winter too, I rather like it! Still have that weird aux-belt tssh tssh noise but that wears off by the time I've got to Middleton
I wouldn't be surprised if it smokes like hell when you've had the DPF removed. I think you have another problem, which is not throwing up codes, but is clogging your DPF. I don't think your DPF is faulty at all, I think it's doing it's job.
Time will tell of course - I could well be wrong!
P.S. Mine sounds like a tractor in this weather also!
Diesels with a DPF produce no/negligible soot. You can see this by looking at the exhaust of a DPF-equipped diesel and comparing to a non-DPF one. Immediately obvious. As such, if they adapt the smoke test to look for soot (not just accumulated, but actually smoke being produced while the engine is running), and find it on a car that is meant to be DPF-equipped, then surely that indicates either no DPF or faulty DPF, and therefore fail?
All of the above could be done as a "visual check". I agree, the OBD sounds way too complicated/unlikely in my opinion, at least for the early stages.
If they do just check for the canister, I'd be disappointed. If diesels are kicking out all this rubbish which is bad for us, and something can be done but people are bypassing it, and getting away with it, it's a bad state of affairs.
The biggest issue is mis-selling. I went into buying a DPF-equipped diesel eyes open. I don't do any of the nonsense I hear about; it rarely goes above 2K RPM, put it in 5th on the motorway as soon as sensible, gets used on short journeys all the time (used to not go on the motorway for weeks at a time, getting me to and from work every weekday with stop/start 10 min journeys each way). Never had a single issue with the DPF in over 20,000 miles. Had the Eolys fluid topped up at 37,500, cost me £100 which I've easily saved in tax. From what I gather, needn't have got the fluid topped up so early, as I've seen reports of people not topping up until 50/60K. Not worth the risk with the EML and extra charge for "diagnostics" though IMO.
I acknowledge that people have issues with these things, but there must be another issue that'd otherwise cause excessive smoke, but is instead blocking the DPF, or the car is just wrong for the types of journeys they do. As I said, probably been mis-sold.
Can't remember the exact dates, but the later mk 2.5 models had a coated DPF. The date was definitely in 2009, as I just missed it (mine's a December 2008 model).
Anyway - @exponential - I'd look at the other issues. Based on your driving, and my experience (along with someone else I know who has the 2006 model), I do not think you should even notice your DPF is there.
On the black oil front, I've found mine is instantly black, within around 100 miles (if not even less) of a service. Have proved this as well, checked it before I left the garage, then a short while after. I believe this is normal for a diesel. The smelly thing might give you a clue though!
Regarding the turbo going, I think you're referring to the banjo bolt that used to clog starving the turbo of oil? This was definitely fixed in later models, and saying that, I know of two other 1.6 diesels that did have this issue, and the turbo's still going on one, (90,000 miles) and went at around 120,000 on the other.
Sometimes mine sounds tractor like, sometimes it sounds refined. Often related to being cold, but sometimes it's just different on different days. Sometimes my ears are blocked a little also! (No joke, this really makes a difference to me!).
