I've got a 2.2 DTi (Y22DTR). 60Kish on the clock. '04. Regularly serviced
Every time I switch on the ignition (unless the engine is still hot) the EML light comes on an stays until I give it a blip of the throttle.
More recently thought it starts going into limp mode while driving which sometimes goes away of its own accord in 30 secs or a power cycle with the key clears it out.
I've had some probs already that I thought had sorted everything. I've replaced all three of the turbo boost pipes (larger pipes) as I had splits developing. I've had the EGR out and cleaned with carb cleaner, I've done the same with the boost sensor. For more background I'm running the airbox mod with a K&N. I also ran 10K boost though, I've a sneaking suspicion a bit of it trickled back down the air intake to the MAF, though not 100% certain.
Anyways, I've been to the dealers today and the following fault codes were there:
1) 0234(5A) Boost pressure control circuit negative deviation
2) 0380(0B) Glow device circuit low voltage
3) 0400(F8) Exhaust gas recirculation valve feedback signal malfunction
4) 1105(FA) Barometric pressure not plausible with boost pressure
5) 0105(FA) Barometric pressure not plausible with boost pressure
The mechanic cleared out the codes, went to for a 3 mile test drive and only the last two remained on the system. They've said the following though:
1) Can be fixed with ECU reprogram
2) Glow plugs probably need changing
3) I started the engine without the EGR valve in to blow the crap out, and this might have caused this, hopefully it won't come back
4&5) They said this could be a few things (split hoses etc) and could book me in for an hour investigation
Otherwise the car drives normal though. Good mpg, no smoke that I can see, maybe a bit missing on the throttle sometimes but could just be in my head.
So the question is, does anyone have any experience with 4&5. I'm keen not to burn money where I don't have to but would definitely like to get it fixed. The only post I could see with the codes on here was one where the guy's car was pretty much dying... hoping I can avoid that.
I was going to replace all of the boost hoses (http://www.vectra-c.com/forum/showth...ght=boost+hose) and see if I can clean out the MAF (not actually looked properly), any other advice so I can start ruling stuff out?
