I bought a seriously cheap hdi estate 2001 towbar ect it was too good to pass on! knowing it had problems I set to work Now I've managed to work through a fair list I'm starting to see the light! BUT .......
Always a bloody but isn't there!
Engine runs fine burns clean but lacks low end grunt
Scans fine but that's with an Autel I'm sure something is not showing
Maf makes no difference
No eml even when maf is unplugged?????
Im going to blank the egr over the weekend
Pretty sure the turbo is on its way lovely noises this morning on spool
Later 3 plug Bosch Ecu
Am I missing something what's the best scanning software?
I could pull my hair out at times I have no luck but I guess it's to be expected with over 200k

I would suggest getting a copy of PP2000 and get that on there. That way you can see all the live data and work out if something is starting to fail.

With that mileage it's probably a combination of things wearing.
MAF doesn't show the EML on later HDis.
I would say it's a stick EGR or a boost leak somewhere else tbh.

That's interesting to know I just assumed with the maf unplugged it would show a fault! In that cause there's no difference unplugged so there's my first fault found!
That's the problem at the min I can't see live data so I'm guessing!
PP2000 it is then! I will blank the egr tomorrow that was one of my first thoughts as for boost leaks I'll need to strip it all down and inspect without the intercooler there's only one pipe lol

It's not just one pipe really though, that has silicone joiners each end that leak, plus the inlet elbow to Mani join will be leaking as well.
But yeah sounds like you've got a dead maf!

If MAF is unplugged, it's still slow and it doesn't smoke like hell, there's no EGR problem.
Plug into pp2k and note the MAF rate and Injection Quantity.

Actually, just thought, it's a later one, ensure the doser valve isn't jammed/jamming as that would cause issues although I'd be surprised if with the MAF unplugged it doesn't smoke like hell...

Seriously, if the MAF is unplugged, it uses default airflow values that give pretty much full power... If unplugging it makes no difference, there's something else at fault.
If there was a fault anywhere causing lower airflow than is required for full power (I. E. EGR jammed open, doser jammed shut) unplugging it would cause bad smoke (since substitute airflow values give full fuel).

Well isn't this going to be fun! 2nd guessing it must be a fuel injection fault! it runs as clean as a whistle! Not sure why no dtc's showing I'll get myself pp2k that's the only way I'm going to get to the bottom of it as my autel doesn't support live data! I'll check over everything else just incase I'm still going to blank the egr off! Would you remove the air doser? Anything else you can think of I'm not much of a hdi expert?

Hi sorry if this is a bit of a hijack but since pp2000 has been mentioned can anyone recommend a supplier that is reliable and not a cheap chinese job, when I spoke to hdi tuning they said only buy the one with I think phillips chipset or summat like that
Thanks Simon
