E46 Limp Mode 320D
Posted 28 October 2012 - 07:12 PM
My 320d developed a problem where its got no boost under full throttle. it feels dead, it just started to day, i removed the plug for the maf and it didnt make any difference. I have inpa is there anything that can be done there? the dde3.0 doesnt work with inpa on my car but. anything it could be, my car was really low on fuel at the time but i doubt that would make a difference, anything i can check ior anyway of getting codes via inpa without going into dde module. There are no EML lights etc

egr valave was cleaned and then disconnected a few months ago,
How do i read the codes with inpa if the DDE 3.0 unit isnt comaptible with my 136bhp m47, is there somewhere else i can see it, or get live readings through the instrument cluster module with inpa?

Have you tried plugging the egr back in? It def sounds like you needs the codes read and cleared

It's a shame you're so far north, i'm in Co Kerry at the moment, and you could have copied my install media.

You can confirm it by unplugging the maf because if it's not connected the car runs on preset values, if it runs better with the maf disconnected it will confirm you need to replace it.
damn, just read the codes it says air mass meter too small, if i clear it, the error stays away until i rev the car a bit, then rescan for codes it reappers as air mass meter, error currently active. replace the MAF then.

I have the same engine as you and my maf reading in inpa is 32.36 at idle,but my car is going grand.What is that dde3.0 compatibility thing you mentioned?There is a change to the inpa cfg file that will allow
it kind of runs the same, but witout the chugging, i was looking at the live data from inpa before i patched in the dde 3.0 ECU compatability, the maf was reading a crazy value like !20.33 etc and not changign with revving, unlike the other sensors
dde3.0 to show in inpa but the menus will be in german.

When i need a new maf i will be going for the pierburg maf sensor.Apparently it gives good results in the m47 engine.

a local bmw specialist quoted me €120 for a bosch Maf and i thought that wasnt bad but then he said actually that for a used one, a used one on ebay is like €40, i didnt buy OEM or peirburg, i bought o generic one with a 2yr warranty as i dont think ill have the car for longer after xmas anyway.
