Gurus.. Engine running rough throwing cel. 239 is cyl 2 misfire 145 is cam position circuit a bank 1 circuit open, 21 is small leak on evap emissions but what is error code 1?
I'm looking for the leak which apparently it is a vacuum hose but I'm having no luck finding. I did locate a small crack in rubber boot after maf which I have temporarily patched. Your suggestions?? My Bentley manual doesn't show a dme 1 error code ???
EdJack thanks! I noticed these are for e46 which has a m54 engine in it with a DME 43 version compared to my m52tu with DME 42 vs. The engines look identical from what I can see (my son has the e46 m54). So the codes should be relevant for both?
Here's the update: I found a small leak on the boot after the MAF sensor where the vacuum hose connects on top? I sealed this and 2 of the codes went away. I'm now left with DME error code 1 and 239 both a result of cyl 2 not firing. I labeled ignition coils from front to back a-f corresponding with cyl 1-6 and then switched out ignition coil A with B. The results were errors 1, 239, 238 and 29. Now misfire on cyls 1&2. I cleared the codes then switched back the coils. Error code is now back to 1 & 239, cyl 2 misfire. I leaning towards the ignition coil "B" on cyl 2 is bad. Your thoughts guys ??
