so on the way home last night my bargain basement 2006 Renault Laguna 2.0 dci dynamique died

fault on the dash check injectors

a quick obd scan returns the following

P0235: Turbo/Super Charger Boost Sensor "A" Circuit
P0403: Exhaust Gas Recirculation Control Circuit
P0409: Exhaust Gas Recirculation Sensor "A" Circuit
P2002: Particulate Trap Efficiency Below Threshold bank1

Pending Fault Log
------------------
P0089: Suction control valve stuck
P0340: Camshaft Position Sensor "A" Circuit (Bank 1 or Single Sensor)

when you turn it over you get what i cash only describe as a weak sounding ignition

im thinking map sensor.

anyone got any ideas other than scrap the *****

Whats it like on fuel,
How much oil have you used.

DPF wants cleaning,, get under the car, find the two hoses pull one off, any of them.
See if your car will now start..

Does your scanner read live data, if yes, crank the engine with scanner on, see if you get a RPM signal..
Not many sensors stop a car from starting. Same sensors that will make it fail while driving cam or crank sensor..To be fair, its really only two sensors or a fuel issue..
See if you can get a reading, ..

All above faults..

P0235: Turbo /Super Charger Boost Sensor "A" Circuit = Usually a MAF sensor issue
P0403: Exhaust Gas Recirculation Control Circuit = Stuck open
P0409: Exhaust Gas Recirculation Sensor "A" Circuit = Stuck open
P2002: Particulate Trap Efficiency Below Threshold bank1 = too much ash in DPF
unlikely any will stop your car while driving. MIGHT stop your car from restarting.
