you mean EML light looks like a engine block, need to scan the car see what codes are stored in ecu,,, eml light could mean anything its just there to tell you it needs scanning,,, no point using a cheap a handheld scanner most wont read P-codes dealer only,, cheapest scan tool that will autocom cdp plus on ebay works well, or wurth snooper same thing £50 on ebay without next to no chance to know whats going on
Turbo stop and back
Good morning group! I have a issue wit my Cooper S 2008 when I accelerate strongly and let the turbo have a large discharge and always turn on the injection light and the turbo stops working, if I do the same from low RPM accelerates (with the light turned on totally without the turbo) until high RPM and let them lower RPM, the turbo works again and the injection light goes out.
If I have a progressive acceleration, and quickly change the gear (without the turbo discharge) this does not happen.
The car has blow off valve and was remapped, but this issue appeared before these modifications.

Hey Mike, thanks for you help. Well the car was in the mechanic for 3 days in a official BMW and Mini place and they couldn’t finde anything, but for me looks like they didn’t check nothing. They said for me as the car has “modifications” it's hard to check it, the car has only the blow off valve and remap and this mistake was made before that to make both.
But yes you’re right need to be scanned and what is the historyI will try to find a different place to check this here in Dublin.
But in the main time maybe someone has the same erro or knows what can be.
Thank you!

having a remap wont effect EML warnings unless with in the mods the self check eml file for that controller has been pulled off ecu,, ie on say a egr or cat some of the files when these are removed ie i have decat on mine so the map was wrote to convince the upstream and down stream 02 sensors there is a slight difference in the signal voltages so ecu thinks the cat is still there ie if cat was there still there would be a difference in signal voltages,, when when t removed they will read same voltages,
as for remapping a broken car before fixing the broken part is a hard one not something i would do run all kinds of risks with hurting it for a start,, also will like you are now in nowhere land with knowing whats going on,, is it possible to reload the standard map then code read it again see what it flags up would be what we would do,,,
that said just because a car has been mapped or mods its normally possible to worl out whats doing what by a live data run or two but like said before need a good scanner,,
as for your approach of as anyone else had same issues and what could it be,,, so many things on them that will give same outcomes,, so needs to be scanned correctly and a number of tests done,, ie smoke test the boost side of pipework, smoke test the vac side of it,,, one thing very common on n14 engines is under the inlet manifold right at bottom of the engine block there is a vac expansion tank it had two small vac pipes going to it it also has a recess that collects any oil leaked from pcv or vanos valve at rear of engine this over time makes the rubber go soft this dumps the vac thats needed for the waste gate on turbo...failing this then put a vac gauge on the turbo wastegate check that it gets to max travels at 14psi on bump stop and stays there ie no leaks, failing that map sensor ie n14 has two one on inlet manifold and one on pipe at top, with diagnostics ca see what boost is actual and prescribed figures, ,

I have a Ultra Gauge EM Plus v1.2 OBD2 Live Data Scanner and there i can see the PSI in maximum accelerations the scanner show me 19psi. So I have good pressure but im after you say that should be around 14psi now im wondering if if 19psi is not is too much? .... All this problem can be relelated with the "Docas Turbocharger Diverter Electronic Position Sensor" ? I heard that the diaphragm that bring inside breaks very often. But im not missing power just the all turbo when the error appear haha?
to check the turbo wastegate pressure on control vac circuit will need like below is cheap
use it to pump the wastegate and see if it holds its pressure as well,, also like i said before the wastegates tend to hit the vac bump stops at 14psi-19psi depends on car and turbo
