Thread: Fuel pressure regulator?

Any smoke?

Hi all,

Thanks for the many replies. Such a great forum.

So to answer / confirm some questions.

TD5 Auto
360k kmsTurbo hoses recently replaced with silicon ones
turbo wastegate not sticky as far as I can tell - have also shortened actuator rod
No smoke
Starts first time on the button
No EGR
Cleaned the MAP
Cleaned and tested without MAF
Not heard of AAP so will investigate this
2001 so no nanocom unfortunately... (would a hawkeye tell me as much? Not seen much info on these...)

I've ordered a turbo pressure gauge so will get that hooked up as well to see if anything dodgy going on there.

Cheers

Nanocom will work. It's model dependent, not year dependent.
If you can chase up someone with a nanocom in your area to help.

As I remember it, adjusting the wastegate rod won't actually do all that much in the end.
The majority of the wastegate control is done with the WGM(wastegate module), a small electronic device just below the thermostat housing with three 'vacuum'(actually boost) hoses coming off it.
It's common for them to play up and not give you full boost.
From what I've read tho, the typical symptom you will notice is boost surging.
Happened to my brother's TD5, it would surge, go into overboost and(I think) the ECU would then set a lower boost routine(so it doesn't surge) and it's then down on power.
But again, you'd feel this on every start up, and it'd be noticeable.

Brother's had a nice smooth power delivery but only up to about 3-3.5 K RPM, then it felt strangled. You could rev past this rev range, but it felt 'wrong'.
Once I'd changed the WGM, power came in very nice all the way to 4K .. that I felt was more than enough for me to push too, considering it's not my car.

Nanocom works on my 99. You need 2 unlock codes, one for the body stuff, and one for the Td5 ecu.
Just a process of eliminating possible issues. Still needs fuel, air in the right mix, and instead of ignition timing, you have injector pulses.

If it has had an overboost logged (very likely with shortened rod), you will need to clear the fault for starters.
It will have reduced fueling and slow acceleration following an overboost condition.

Hmmm! OK I somehow got the impression the nanocom only worked with 2002 onwards.

Looks like I have some saving to do.!

Although that has just complicated decision making on what to spend on next...

No it hasn't - Nanocom 1st - will save you heaps in the long run!!!

It does when it comes to remap via OBD but for all the rest it works on all
