Where is the body ecu located

It is inside the transmission.

I’m happy to help further over the phone at https://www.6ya.com/expert/anthony_dda4e0152e94f3c0

hi, the airbag ecu is in the bottom of the center of the dash.
cheers

I am sorry but we have no way to cross reference that information, contact the MB dealer parts dept to verify, but off the top of my head i would say no, the Germans would not make it that easy.

have heating in my peugeot 406 hdi when car is ticking over but when i drive for few mins the heater goes cold

If you mean the vin #, yes, probably. Vin #'s do show the engine code, but you might want to visit a peugeot forum to find it.

I would change your throttle position sensor (TPS) or at least check all related wiring, fuses and relays concerning this device. It is located on the outside of the throttle body at the end of the throttle plate shaft. Its function is to send a an electrical signal to the ECU that correspnds to the position of the throttle plate. Your TPS is not sending a signal to the ECU so the ECU does not know to inject more fuel in response to the throttle being opened. The call for more fuel in the absence of immediate input from the TPS is being made to the ECU by the Manifold air pressure sensor but this can a take a second or two to respond to pressure changes, hence the hesitation in acceleration. One really quick way to check is to simply disconnect the TPS electrical connector. If it were running normally you will notice an immediate change in engine idle, as your is faulty you will notice no difference

your ecu monitor.. emissions control unit mod is done! i dont think this is a cheap fix. either wait for warmer weather,, sell the car or find a dealer to fix this diesel puppy...word of advice .. dont buy peugeot in this country .. or any country...joke.!!

see the headlight regulator on the driver's side. You'll then see a plastic Bolt. Turn 90 degree counter clockwise with a 2 Pence coin and open the Flap. Voilla the OBDII Plug is there.

you shouldnt have to reprogram the ecu but it wont hurt to reset it. To reset the computer take the positive cable from the car off the battery and give it 3-5min to discharge then touch the positive cable from the car to the negative cable (still attached to the battery) for about 5 seconds and then hook back up the positive post and that will reset the computer. not sure how much difference it will make but like i said it wont hurn anything.
