I have recently acquired a 2003 Vauxhall Combo 1.7 (Isuzu Engine) Diesel Van, previously to me owning it the previous owner had changed the MAF sensor, for reasons un-known, i carried out a engine service on it, all the filters, oil, air and fuel, as well as pollen, after sealing the bulkhead for a common known water ingress issue, dried the interior out, whilst having the vehicle running, had a orange spanner light appear and remain on, initially i thought it might of been a service light, but it wasn't as had already reset that, then on pressing the brake and accelerator with ign on eng off, flashed a code 0105 , un-sure of the code at time it referred to boost pressure/Barometric Pressure not plausible with Boost Pressure, but i hadn't touched anything like that, though i had the battery dis-connected, on sorting the bulkhead concern out, on checking around I noticed a fuel leak, via the fuel advance timing solenoid valve, again a common fault on this particular vehicle, and on doing home work (looking on forums on line) before commencing the replacement of the solenoid valve, alot of people were saying contamination of the loom and poss edu, but no real issue found with loom or edu when cleaning diesel from loom, replaced the solenoid valve, with out removing the fuel injection pump, replaced the timing belt (kit) at same time, got engine running and ran very sweet for a Di engine and at this point the spanner light was out, BUT then i spoke too soon, as it came on, now bearing mind the vehicle hadn't really moved and was only idling, I carried out a pedal test again, again 0105, I tried reading the code with my elm327 code reader, it wasn't able to communicate with vehicle ecu, got a mate of mine to read it with a snap-on solus scanner, cleared to code, though code came straight back with in minutes, and came to conclusion poss fault with the boost pressure converter at the back of the engine, as a lot of the forums online were saying was a MAP sensor fault but this vehicle does not have one anyway that i have found so i keep hitting dead ends, as only have a MAF, checked the pipe work to and from it, and to the similar valve that controls the egr valve, replaced and made secure the pipes to these valves, though original idea was going to swap the valves, ran the vehicle and gave it a good hard road test, as previously the vehicle had been stood for a while, performance improved, drove like a dream, no light on for all the time i road tested, but when left idling, the spanner light came on and same code on pedal test, next suspected the pressure converter, got replacement pressure converter, light went off and performance again good and once got to normal engine temp and left on idle, light straight on again, next thing to look at, in ref to forums, was the EGR valve, as we all know how reliable these are ,lol, removed it, low and behold, sooted up, cleaned out with brake cleaner, was able to move the valve ok, though wasn't able to vacuum it, re-fitted and ran, spanner light on again, though road tested vehicle and performance improved and turbo boosting as it should, checked, which is what i should of done before replacing pressure converter, feed and earth to this, battery voltage and good earth, so blank drawn there, as really don't know where to go with it now, as i do appreciate, really need a decent code reader to remove the code and poss read live data, but in a way feel this vehicle is too early for obd2, part of me thinks clearing the code may cure it but not convinced, worst case sinario is the edu, as some have said about a dry solder joint, but don't have the code for the spill value.
Again forums and Links to this vehicle has drawn a blank and not relevant to the concern i have, as they all mostly refer to a MAP sensor, which is where i click off the link, i am really hoping some one out there is able to relate to this and may poss have the solution to this problematic concern with this particular vehicle.
Thank you
