Hi All, Looking for some advice and possibly a friendly enthusiast in the Southern Highlands NSW

The issue: Some months ago my pug broke down, Low pressure on injector rail. Also at same time DPF additive + )i think) ECG warning.
I managed to narrow down the fuel filter had it tested and which failed. Price for part btwn $1400-2200. With 500K km's on it:
a) is it worth replacing given I may end up with trouble on trouble
b) What's involved in going thru repairing the DPF/ECG?
c) is there anyone who knows more in my area that would be open to collaborating on fixing it with me?
d) should I just send it to a wrecker or sell it (given it's not going to fetch a great deal of money)?

I've owned it since new and it's been a dream car. I kind of want to see if I can get it to 1 million but that's a big time investment for someone who really wants to get into an Electric vehicle ASAP.

The final issue is it's rego exxpired yesterday and I have a 2nd car so I basically have 90 days before it becomes a hassle to get back on the road...

Any thoughts or advice greatly appreciated.,
 
Is that a 2.0 HDI RHR engine? You can get more than 500,000 out of one of them.

I don't know how a filter fails, except by getting clogged up. Do you have more information?

If you put in more particle filter additive, it needs the computer to be told. This needs appropriate software on a laptop.

The particle filter if clogged may only need a forced regeneration ordered by the computer, again needing the software. Diesels need regular open road/motorway runs or the inbuilt regen won't occur. It may not need "repair" as such.

Have the OBD codes been read? You need these to make sense of trouble. If you don't have a reader Supercheap places can do it for a fee. There is one at Mittagong. A pity the rego has expired. You can buy a cheap reader for $60 or a bit more.

Is ECG exhaust gas recirculation? I'm wondering too if you have the famous plastic Y piece crack in the vacuum line at the front, which plagues older RHR engines. The fix is trivial.

@seasink I hadn't logged back in and thought that I would get an alert or something if someone replied. Thanks for your feedback. No I realised I said "Fuel filter" is wrong. The High Pressure fuel pump failed. The OBD codes were: P1207 fuel pressure regulator control. Rail pressure too low on starting & P0087–Fuel rail/system pressure–too low bank 1.

Its RHR-JT7–Generation 1 (2007–2021)2.0 L DW10B I4. before the fuel pump went it had a dpf warning. The car has lived on the highway, possibly why it's been so low maintenance all of it's life.

Not sure how to determine if it's gas reticulation or about the Y piece vacuum line (is this the line that is part of the top engine cover?).

Still haven't made a final decision on what to do, getting it registered again isn't too daunting have just been rather lethargic about making a decision... Thanks for the previous input and any other input you might have.
 
It does have too low a fuel rail pressure P0087, but P1207 is an operating range fault with the fuel pressure regulation solenoid at the HP pump. These are a separate part.

Get onto someone like Dapco Auto France with the VIN.
 
Thanks, I'll try Dapco for the complete part. I left the pump with the person who tested it for me (or didn't). I resolved the next step was to replace the entire pump inc solenoid. Should have asked questions here a long time ago.
 
@seasink Thanks for the Dapco suggestion. They are great. My next question/issue is with the new pump installed does the new pump need to be programmed/coded before it will work? I'm now getting some fuel to the rail but it's def not at high pressure. anyone got any suggestions?
 
A new pump? There are a large bunch of precautions and cleanliness stuff before dismantling HP systems and seals. I know the DW10F has a pump timing procedure, but I don't know of a DW10B timing procedure.

Only tighten the HP connection to torque when the assembly is in place. Check for leaks and bleed the fuel system.
 
Yes a new original pump from Dapco. No idea about the timing, I took the pump out ages ago and just installed the new one in same position as the old (FIngers crossed maybe).

RE leaks, can't see any but as for bleeding, the only bleed spot I see is the filter. I tried to bleed air out of the injector rail by backing off fuel line at one injector. there is fuel in the rail but it doesn't appear to be at pressure.
