So what are your cars symptoms when the EML comes on ?

From what i can see its constantly the ignition path
either the fuel suply, fuel ignition are in trouble
Maybe the one thing that's controlling it ? the ECU ?

my car goes into limp mode and doesnt go about 2000rpm. peugeot told me it was just the coils that needed changing even though i had already had them changed twice. it could possibly be the ECU my car is currently in the garage again waiting to be tested again, but from the sounds of it, it could be the ECU. thank you for your advise i will pass this on to the mechanic to see if he can check all of the above.

Coil packs do fail,but not on a regular basis. It does sound like the ECU might be behind the issues. But a full diagnostic from Peugeot should really show u- the actual issue. (In theory).

Hello there , did you get to the bottom of this as I also have the same problem ?

MAF or Map sensor checked poss. vacuum leak on the air intake side?
Throttle position sensor?
Fuse or relay malfunction as per a BCM issue
Crank sensor ?
fuel pressure sensor or dirt in fuel rails system?
never rule out anything that sounds unreasonable when the car is continuously in limp mode
