Red diesel seems to knacker the injectors on these. Not sure why, guessing there's not as much lubrication or just the conditions it's stored under. Common rail + red = problems.
If you're going to shell out for a new set then stop using it, or just keep replacing them with cheap injectors.

It's a car I bought cheap hoping I can repair it cheaply or I'll break it, had red diesel in when I bought it
RE: White smoke running shit UPDATED - mcglynn - 06-02-2014
Depends on the quality of the diesel. If you are buying it off a reputable company red wont ruin injectors.
I doubt farmers would run hundreds of thousands of pounds worth of equipment on it if it was harmful

That is a good one to consider looking at.
BUT, I know HDi110's can be very picky over all this stuff and usually instantly throw up codes to do with EGR expected vs actual received flows... if something was way out here then I'm surprised it hasn't thrown a code.
Best way to check EGR is to just watch the valve at idle and blip the throttle a bit. If it's moving chances are it's fine.
In any case diesel out the back means rich running (EGR stuck open), or simply not burning through compression ignition in one cylinder, which might explain the very rough running.
Hard to diagnose over the internet of course... just keep checking stuff and I'm sure it'll become clear

I'm going to nip and borrow a scanner tomorrow see if it comes up with anything
It's nigh on impossible to diagnose Over the Internet but any advice pointing me in the right direction is muchly appreciated
There is a vacuum solenoid near the battery that I believe is for the egr? There is no electrical plug goin to it.
Before I bought it the car had a engine Chang and hasn't run right since
Such cowboys pipes hanging everywhere things not plugged in
RE: White smoke running shit UPDATED - Toms306 - 06-02-2014
Sounds like a decent buy then Danny....
RE: White smoke running shit UPDATED - Danny2009 - 06-02-2014
52 plate 307 hdi on 120k with sp kit and challangers for £200 couldn't say no
I did intend to break it but it's really clean so wouldn't mind fixing it and selling it on
RE: White smoke running shit UPDATED - Toms306 - 06-02-2014
Ah that is a good price, fair play!
RE: White smoke running shit UPDATED - mark306 - 06-02-2014
It could be heating oil not red diesel as used by farmers, this has much less lubrication than red or wight diesel and can cause loads of problems long term.
Either way don't get caught using it on the highway, loss of car, big fine and big tax bill is what you'll face.
RE: White smoke running shit UPDATED - Danny2009 - 06-02-2014
i know its illegal mate i didnt put it in, thanks for the heads up
Isnt red, heating oil, gas oil all the same stuff?

You may not have put it in but it's you or the next owner if you sell it that could pay the price.
I'm not having a dig at you, just making sure anyone that reads this thread understands the implications.
Red and gas oil are the same thing but heating oil comes in grades, 28 or 32 second (or something like that), it a viscosity rating.
As it's designed to be used in a burner not a compression ignition engine it doesn't have the same lubrication properties or additives to help clean burning, this could cause pump and injector damage.
RE: White smoke running shit UPDATED - Danny2009 - 06-02-2014
ahh rite i didnt know that i just assumed it was just different names for the same thing.
Yea if i end up fixing it and selling it on i will be draining the tank and refilling it.

To remove all traces you'll need to steam clean the tank, change the fuel filter and flush the whole fuel system, even then some may still be detectable.
RE: White smoke running shit UPDATED - Danny2009 - 06-02-2014
So if it's been ran on heating oil it could have f*cked the high pressure pump and injectors?
RE: White smoke running shit UPDATED - mcglynn - 07-02-2014
If its been ran on kerosene it probably will. Its similiar to running veg on newer cars.
If its red then its gas oil (red diesel). They will run fine on this unless its been washed down with kerosene, eg diluted.
RE: White smoke running shit UPDATED - Danny2009 - 07-02-2014
God knows going to end up breaking it at this rate
RE: White smoke running shit UPDATED - Tom - 07-02-2014
Have you not just tried it on diesel Danny? Just out of a can... Actually thats probably a pain with a lift pump and stuff :/
RE: White smoke running shit UPDATED - mcglynn - 07-02-2014
Get a set of known good injectors, and try them. Worst case you can sell the Injectors on if they dont sort it. Im near certain its them.
RE: White smoke running shit UPDATED - Danny2009 - 07-02-2014
Fuking hate hdi give me a xud any day
As you say be a royal pain in the arse with the lift pump ect
Wouldn't there be signs it's injectors with the leak off test?
RE: White smoke running shit UPDATED - mcglynn - 07-02-2014
I never done a leak off test myself, but mine would spew a shit load of smoke out over 3k but ran perfect under that. I doubt a leak off would show that fault as at idle the car was perfect.
RE: White smoke running shit UPDATED - Danny2009 - 07-02-2014
Yea fair point that going to check egr if that's fine buy a set of injectors off eBay and if that Dosent sort it well it's getting stripped lol
RE: White smoke running shit UPDATED - mcglynn - 07-02-2014
Aye worst case scenario you can flog the injectors on again. Get a set of washers for them too to be on the safe side
RE: White smoke running shit UPDATED - mattgreene - 07-02-2014
HDI's will not run on red!, tried and tested, found out the hard way, drain the tank, change the filter refill with 5 liters of white, run till stops then refill with white diesel. All my hdis wont run on red!!
RE: White smoke running shit UPDATED - Danny2009 - 07-02-2014
It runs though just unburnt fuel out of the exhaust
Going to get scanner on it tomorrow if there's no codes it's getting stripped

My HDI ran 30k+ on red still pulled 133bhp on the dyno. No problems at all bar a engine loom burning out. Lucas pump on a xud tho i dry'd the pump out on the motorway struggled to run and when it eventually did die took some getting going again on white. Never ran right since then. Hdi tho perfectly fine
You can always just get 1 injector if its just the 1 that's likely to be dodgy. I would maybe try running it on a can of white with some injector cleaner in.
White smoke running shit UPDATED - mattgreene - 07-02-2014
Ah right, must have just been my motors then!! I always used to run on it but now I've got a bit older lol I don't bother
RE: White smoke running shit UPDATED - mcglynn - 07-02-2014
Its probably washed with kerosene.
I know of a few that love red
