Hi folks,
I bought a crafter last week but it has an issue….
I’m trying to understand what is going wrong but I need some help.
I have a copy of vcds but if I’m honest I’m a little out of my depth with it and need some guidance.
Yes, I should take it to a garage, but right now I’m out of cash.
I got a basic obd scanner, it first threw up a po40100 code- insufficient egr flow , I cleared the code and the lights went out.
I drove it and it drove fine , smooth engine, all normal, felt like turbo was kicking in , but as soon as I went over about 2.5k rpm it throws its hand in and goes back to limp mode, engin man light and pig tail flashing,
Clear the codes, Same again. But now the po40100 insufficient egr flow code isn’t there, instead I’ve now got po299- under boost. Boost control pressure not met.
It starts ok, it ticks over ok. But it reeks to high heaven of over fueling or exhaust fume.
Real bad.
So, given the initial egr related code, I stripped the egr valve off, expecting to find it clogged.
It wasn’t, infact it was surprisingly clean. It certainly didn’t feel right that the egr was the issue, so I put it back in the cooler and refitted it.
I tested the egr solenoid and can see it motoring fine. I happy that it opens and closes, seats correctly and is not blocked.
Ive then looked carefully for vacuum leaks, I can’t see or hear anything.
I then got a lead and installed a copy of vcds.
Cleared codes, ran the van until fault appeared at 2.5k rpm, and re read codes. Again I got po299.
With the stink of the van I’m certain it over fueling itself .
I’ don’t know enough of the technicalities of vcds to test the n75 or Maf or map sensors…
I’ve ordered a map sensor to try as they are cheap, but I can’t even find where it’s located![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Where is it?
I went to try the n75 valve and it looks like there are two ? Which confused me even more ….
Finally, tonight I tried to blow smoke up the inlet hose to see if I could spy any leak anywhere, but the smoke I was pumping in the air didn’t want to flow in, like I had a blockage ……should that happen or would that indicate something is wrong with the turbo? Something stuck shut ?
Guys, I know I’m out of my depth, but I’m just trying to learn more and see if anything obvious shows it self…..
any advice is welcomed
