My BMW is in limp mode

A NON USA CAR, where is it what country? (engines and EFI vary by, countries sold to) (2 engines in 2001) near same but....what/?
1.3 L M13A I4 (petrol) with VVT
1.5 L M15A I4 (petrol) with VVT (VVT can fail and lose power too)


well, you did not do the right tests.
not using a scan tool first is #1 cause of going astray, do that first.
Fuel consumption low tell me it, the ECU is in limp mode. and the ECU has lots of DTC errors you are ignoring.
low power has many causes. not just one #10 filter. inside the tank
let me list them to you , in no order, and is ASE class 101 basics, all the way,

1. low fuel pressure, bad filter,bad pump bad FPR fuel pressure regulator. we use a hand tool gage to find that.
2. bad MAF sensor has this, NO ENGINE STATED BY YOU!
3. bad spark if misfiring, ever do a tune up in 60,000 miles.????
4. Bad fuel ,
5. clogged or leaking fuel injectors.
6. bad engine, is compression at spec? (more tools)
7. CAT Melted, (ignoring those DTC error caused this)

that is about it, can go more, but you have no tools to test, so find a shop , to fix this car, as they SURE DO HAVE all tools to do that job right and fast.

and you don't trust the dealer? Is that what you're saying?

need to plug it into diagnostic machine to get further
fault code and go from there

You can't reset the limp home mode, you must take it to the dealer and find out why the computer control is asking for limp to be engaged.

limp mode is initiated by the ECM when a major problem occurs in the engine or transmission
such things as low oil ,over heating, inability to select ratios --basically the very costly items to replace --
run the fault codes to determine the sensor/s that have set the ECM off

You put it in park and turn off and it resets. You turn it on and it runs awhile and zeros out. Try looking at the parking sensors and the on board computer.

Hi
this is the Variable valve timing (VVT), bank 1 - limp-home mode - full stroke position not reached P1062 and the P1050 is the VVT control unit itself, try checking the connections to it make sure they are secure, if all looks good, then you might have to change the unit as this will keep making the vehicle go into limp mode.
hope that helps

check the oil level in the sump, coolant level, coolant temperature (overheating), transmission oil level if auto. The limp mode is energised by any number of sensors that register a fault that is detrimental to the engine/ gear box. Run the fault codes and repair any faulty units . Reset the CPU with a scanner .

Now if i knew what you meant by blew ?? then i might have a idea --most turbo faults are caused by dirty oil and changing the engine oil every 5000miles with a filter every third oil change will stop this problem .The other problem is the turbine vanes breaking off or being damaged by grit where the air filter is missing or a pipe loose or split allowing the thing to suck in unfiltered air but i do know someone with one of these and he sold it in the end and bought a transit as the turbo gave up quite often ,but without taking the turbo apart then i couldnt tell you why they are failing but i do know he kept a small hand held diagnostic machine in the cab and when it went into limp mode he cleared the codes and off he went again .Seem to remember as well the waste gate operating piston playing up i think a rubber tube perished so it didnt open and the increase in pressure as the engine revved up caused the thing to go into limp mode as too much pressure was being generated ,the rubber tube goes from the pressure side of the turbo to the piston its about 4cms long so as the air pressure builds up it this pressure pushes the piston which opens the waste gate which is a little flap on the exhaust side of the turbo into the exhaust manifold so when it opens it allows the exhaust gas pressure to go straight down the exhaust pipe releaving pressure on the turbo vanes .If the pressure in the inlet side goes too high then a sensor will put the engine into limp mode .Hope you understand this technical jargon ?
