P0093 Help Needed To Decipher Data

[AF_Tim]

I replaced the #2 injector today.  Leak-off test went great, ran it for a minute and bottles were pretty much empty.

I had about 4 oz after running it for 20 seconds last time.  Tomorrow will be the big test to see if it's fixed. 

I didn't get the new banjo washers for the return lines yet, so think I have a small leak from them. Really don't want to pay £36 for 4 washers. May just use some M8 crush washers.

well done it sounds like it is now sorted,  good luck.

So far so good...mostly. Limp mode is. I longer. Mileage went from 34 up to 37mpg. 1500 mile road trip to France and. Ack this weekend. I'm sure mileage will still go up a bit. 

VSC still pops up for DPF though. Options:

1. Ignore it

2. Remove and soak in DPF cleaner/reinstall

3. Have a company eliminate DPF altogether and remap ecu. £400+.

Remove dpf & egr and make a remap. I made it for mine and now this is a "new" car...

[AF_Tim]

I'm going to search for a thread on the DPF removal.  Don't want to hi-jack this anymore from the injector issue which is now solved.  Thanks for the help everyone, this forum was a life saver.

Last update on this (hopefully), did a 1500 mile road trip this weekend to France and back.  No issues injector wise and Limp mode has yet to come back.  I averaged 37 MPG on the way there at about 80-85mph.  Faster I went mileage went down as to be expected.

Can anybody show me how to do the leak off test I have the same problem and fault codes :( thanks in advance 

[AF_Tim]

Although you can’t see much, you basically need to make a contraption like this.

If one bottle is substantially more full than the others, it would be the injector that needs replacing. I ordered one from a breaker for around £140. It’s worked for 6 months without issue. 

[AF_Tim]

You’ll need to hookup the hoses here, after you unscrew the caps. 

[Elphick91]

Awesome so I take of from the spanner part and not the Allen key.. and do I take around the tubing? I have 5mm tubeing..

[Elphick91]

Also thanks for fast reply. :)

[AF_Tim]

I used connectors like these to shove in the injector and connect to the tubes. I had a hard time just shoving the tubes in to get a seal otherwise. 

[Elphick91]

Awesome i will grab some tomorrow and sort it . Thankyou very much :)

amazing you guys hats off to you all & all the troubles & problems you’ve solved to get the right out come.. i’ve got all the same problems with VSC & P0093.. 

 

going to price up injectors after doing the leak test.. & wow yeah the stress of this problem ii know how you all felt.. thank you very much & very much enjoyed reading this for over an hour.. hats off to you all.. mrdeanhollis 

[Mattu]

Did you manage to resolve this problem as I have exactly the same problem

[AxL.PL]

I read all the answers on this topic.  I am struggling with the same (I think) problem.  The car enters emergency mode but at high speed and high engine revs.  With normal driving, there is no chance of p0093 error.  The only symptom that something is wrong is jumping rpm's (not always) which can lead to the engine off.  The overflow test showed that injector 2 gives up too much fuel.  This injector was replaced as first. It turned out that mine has a cracked atomizer, visible in the photo.  Result after replacement? Nothing at all.  The true is that I have no space to accelerate the car so that it shows p0093, but when stationary, the engine rpm is still jumping.  The overflow test also showed that the injector No. 3 does not give off fuel completely (as if it all went to the cylinder).  For the peace of mind, I also replaced the SCV pressure valve Couse it's cheap. For even more peace of mind car been running only on Liqui Molly diesel injector cleaner for 2h. In short circuit. Result on picture. I'm slowly losing my patient..

Excellent write up from all contributors. Well done and on the other hand so sorry for your loss trying to fix this issue.

Having smoking issue but car doesn't go into limp mode, suspect injector/s and will try the leak test as clearly described 😍

 

Thank you All.

Any help at all would be very appropriated ...I'm thinking it's now leaking injector .I've tried to remove them before but could not get them out
