Problem: P120X And P020X Codes

injectors

I didn't mention the jerks especially because I was having just the same problems as you wrote in your first post. My car is still awaiting diagnosis from a diesel specialist, the first injector which was changed/removed was assessed today by United Diesel (I posted it to them) and they said basically the piezo mechanism had worn out and it was common with high mileages - mine is 145k, what is yours?

 

The injector specialist has reported today that the second injector has also failed electrically, basically worn out, and needs replacing. Apparently it's common, but I am still very curious why it happened straight away after the other one was replaced. And wondering if 3 and 4 will go very soon.

 

One thing he clarified - the Siemens injectors do not need coding, I believe they are fitted to later vehicles around 2005/06 onwards, so not all the 1.8 TDCi Lynx engines are the same.

Hi guys,

 

Do you know how to identify the injectors by their numbers? I mean when I look at the engine then which one is 1, 2, 3 and 4?

 

Greetings,

cauchy

 

PS. I am also about to replace one of my injectors since it started to produce the "check engine" codes every 100 m. I will report how it worked.

You would need to check Google as I'm not sure personally, someone may be able to tell you.

I tried finding this on the web with no success. But I'm pretty sure they're 1 to 4 from left to right looking at the engine.

I hope not, because I was having injector no. 2 replaced, and the new one (shiny and clean!) was 2nd from left.

After a bit of thought: X in "P102X" means the cylinder number and cylinders are ordered from the left to right (right?), so the injector number does not seem to matter.

Just for future reference. Replacing a single injector (on cylinder 3) fixed the issue. More than 500km without a single jerk or error. Thanks for help!
