citroen xsara 2l hdi 66kw siemens cold start problems

[dawnofwar]

hello, i have problem with my xsara and i dont know what to do. Diagnostic dont show any problems. There is video when starting engine at +10C. Also there are some blue smoke, it smels like diesel.

Glow plugs ?

EDIT: ignore, read it as -10 deg

Wouldn't have thought so at +10?C on an HDi,

Plugs were my first thought but i've read they only really kick in at low temps!

The diesel smelling smoke means it isn't combusting properly or theres an injector leaking

i have tested plugs already and one changed but nothing changed. Btw soon i will upload one more video.

Can you get it on diagnostics & read the fuel rail pressure when it's not starting ? Needs a bare minimum of 110 bar to think about starting.

If my memory is correct, the HDi engine needs 150bar on the fuel rail before the injectors are allowed to work. This is according to this document I found;

Well i dont have diagnostics tools so i dont know i need to ask that guy which did diagnostics to my car but for next 2 weeks iam going to be very busy and i will not have time to do it. but as i remember he did diagnostics without working engine.

p.s. sorry for my bad english hope you guys understand me.

Also iam thinking to buy Non Return Valves tomorrow maybe it can help?

The document says it needs minimum 120 bar to operate the injectors, the 150 bar is when pressure regulation starts

The requirements for all common rail diesels are similar but there can be variations between different engines and different injection systems. I am quite familiar with the various quirks and failings of the bosch common rail injection on certain psa and mb engines. Even though i am driving a 2l hdi with Siemens injection and have put over 190000miles on it, i know nothing about the Siemens system and i hope it stays that way. You need to look at the live data with your car attempting to start and when running. Check rail pressure, intake air temp, coolant temp and injector corrections or trim.

hello guys. please look the latest video and you will hear there is weird sound from engine but no one know exactly from where i think it can cause my problem but iam not sure.
You can hear it perfect at 0.2-0,3 min also i have bought new battery but it didnt help.
Non Return Valve also didnt help. Tomorrow iam going to check engines cylinder compression and i willl give more info.

Sorry, check now.

engine compressiong too low. 4-19,5 Bar, 3-20 bar, 2-20 bar, 1-22 bar.
