Timing chain skip on M54?
Hi all,
I bought a 2005 525i with an M54, 282k km on it, about three weeks ago. I thought it lacked some power during the test drive but I drove there in an EV and so I thought I might just have been spoiled. The evening after I took it home I floored it when entering the highway and at 5k rpm in 3rd gear it went into limp mode. Everything went away after a restart. Read out the odb, got P0011 and P0014. By this point after reading some common problems I was thinking it may be the vanos solenoids, replaced the intake one and felt a bit more torque until 1.8k rpm (can't really get to the exhaust that easily). Still, went to a mechanic with it and he tells me the timing chain has probably skipped a tooth, and that the aftermarket solenoids I bought are probably worse than what's already in there. Now both the dealer I bought it from and a trusted friend tell me this (timing skip) is impossible, and that it would run horribly if it was the case (it runs well, smooth idle, just not the power I expected from 190hp, mechanic agreed it was missing power). Do you guys think the chain may have skipped a tooth? If not, any ideas on what may be the issue? The mechanic also sent me these images which should implicate the skipped tooth, but I don't really understand what I am looking at (see attached). |
