Usually you would have an error (engine failsafe) before it would go into limp mode.
I wonder if it's a plugged fuel filter?

But, it was a big initial hit, not gradual, then gradually got worse real fast. Doesn't seem like a filter, unless the pump sucked up something all at once.

Check that code. Nothing else to suggest without them.

Mine did that about 2 years ago, all iI could manage was 100km if I nursed it along had about 500km to get home. The trans felt like it was shifting all over the place used fuel like it was going out of fashon. I replaced the fuel filter, no fault lights came on. I took it into BMW and tested it, Faulty Air Flow Meter

I concur with Slick, code would put us in a direction instead of a motor tear
down.

mine did that about 6 mts ago, turned out to be a vaccuum hose split to do with turbo as mine is a 3.0d, but I presume yours wouldnt have same type system?

This isn't a turbo, so probably not the same thing.
I'll get the codes read and see what I can find. The "used a lot of fuel" comment reminded me, it was using an extreme amount of fuel when limping along. |

OK I read the codes: P0491, P0492, P0440, P0171, P0174.
491 and 492 are same code, different bank - secondary air injection system 171 and 174 are same code, different bank - system too lean 440 - evporative emission system I would guess the the first 2 sets of codes are related to each other, and most likely the 440 code is too. But, what do I look for now?? |

Those codes in combo normally lead to a vacuum leak somewhere. Thinks to check are:
MAF Vacuum hoses Air intake tube Gaskets (Manifold) Valve cover. (Normally a leak can form in the rear corner) Start there since those are the easiest to trace. Someone will also offer some more helpful hints.
