[Engine] Fuel pressure regulator lexia

[Kc1979#]

Hi

Would anyone know why when I test the fuel pressure regulator with lexia it does not vibrate. I replaced it and it still didn't vibrate. I applied 12v directly to both on a bench and neither clicked in or out. Could I have brought a brand new dud.....£60.

I don't want keep throwing £60 away trying to solve.


Many thanks

While it's possible that you've bought a dud unit, it does seem strange that both old and new items don't click when voltage applied? What is the actual p/no of the item you are testing/trying to replace? What is the fault with your vehicle that led to to that component?

Hi 

Thank you you for your response.

Part number is A2C59506225  2.0hdi siemens system

The symptoms was going into limp mode under full load, but very intermittently, the van drove fine and idles well. It threw no codes from what I can see? The limp mode clears on its own after about 20 mins???  

I was just paying with lexia when I found the option to test the fuel regulator  (no vibration) and the other item did vibrate, I forget its name but next to the fuel regulator. 

That fact the fault only happens I'm certain conditions makes it hard to pin point. I prefer it when things just break with a big bang, you know where to look then lol.

Haven't had much experience with the 2.0Hdi engine [which is different to the later 1.6Hdi] but the 2.0Hdi is normally a lot more reliable [I had the 2.0Hdi is my Xsara Picasso in the past and it never gave any problems]

From what I've seem on this forum, the most likely culprits are the EGR valve and the MAF sensor. The EGR valve on the 2.0Hdi is a purely mechanical affair and there have been reports of the sticking open and MAF sensors have been know to give problems on all models.
