injector fault - error df053 1.5 dci 2005
Posted: Thu Feb 16, 2017 7:21 pm
Hi all,
I must say first of all the information you´ve shared in this forum is priceless!
The story of my car... bought it couple of months, a 1.5 dci with 65k miles on the clock and full service history.
4 weeks ago I replaced the cambelt, auxiliary belt and water pump as it was time.
2 weeks ago, after the weekend, it took longer than usually to start, but I thought it was related with the weather; but the issue became more obvious every day it passed, to the point it took a couple of attempts to start the engine. then the injector fault + STOP message appeared in the dashboard for a couple of seconds while driving and dissapeared.
After 4 days of issues with starting the car refused to start with the same message appearing on the dashboard (injector fault + STOP).
Knowing the delphi pumps of that time were reknown for their ability to break down, I replaced the diesel filter and I only found clean diesel and no metal particles ( which was a relief), so I decided to do an injector flow test. I found 1 and 4 gave a greater return, so I took them all out and cleaned them with acetone and ether (by letting the tip to soak in the solvents). New washers and the injectors back made the car start with no problem. I drove it 20 miles or so and went back home. 2 days after refused to start again by cranking.
If I use carb cleaner to start, the car will start and run "fine", with a clicking noise from the engine. Today the mechanic plugged the clip and it returned the error code df053, related to the rail pressure. The mechanic believes it is either air coming in through the HP seals, pipework or knackered injector.
I don´t see how a blocked injector cannot let the pressure to reach the level it requires to start... but I will do another injector flow test again although I am unsure what it can tell...
Any idea?
cheers!
