Crank but no start after 48hrs 2.0 Ecoblue 2017

2.0 ecoblue 2017
Ran for few miles after purchase, then would not start. After clearing codes P062D/U0140/U3000,the car started up. Ran for few miles after dpf warning said drive for more miles. We did that also a forced regeneration and dpf was clear and fine. Took it on another 3 mile run and ran perfectly. Left the van for 48hrs and when I returned it's just cranking again and not starting up. Any help would be much appreciated, I've only had the van a week, not happy...Thanks in advance.

U0140/U3000 are body control module faults, to have them both occur together with the P062D suggests to me that you have an electrical problem related to low voltage.

That would be battery or batteries no good or low on charge, should read at least 12.2 volts with engine stopped and something like 13.5 or over with engine running (the charging voltage can go up to 15 volts, and sometimes peak at 18 volts briefly , as its a smart alternator model .. i have no idea how smart alternators work, so only general info given) note: very important vehicle is fitted with the correct battery with this type of alternator!

Anyway .....check those voltages and if they are not right ..well.. do some other checks on the earths, positives, battery terminals, earths to engine .. and connections to alternator .. take off , de-rust , clean ... and then see how it is then.

This is what google AI says about P062D .... found whilst i was looking up the codes ... don't worry about what it says below, until you go through the electrical earths [/b], positives and charging system.

AI Overview
The OBD-II code P062D indicates a problem with the fuel injector driver circuit performance on engine bank 1. This suggests a fault in the circuit that controls the fuel injectors, leading to inconsistent injection commands or a lack of confirmation signals. Symptoms can include a check engine light, poor engine performance, or the engine not starting. The issue could stem from an open or short in the circuit, a faulty fuel injector, or problems with the injector driver module (EDU) or the Powertrain Control Module (PCM) itself.
Understanding the Code
P062D:
The code specifies a performance issue within the fuel injector driver circuit.
Bank 1:
This refers to the bank of the engine that contains the number one cylinder.
DTC (Diagnostic Trouble Code):
This is the specific error code stored by the vehicle's onboard computer when a problem is detected.
Symptoms Check Engine Light illuminated, Poor engine performance, Engine stalling or difficulty starting, and Rough engine idle.
Potential Causes
Open or short in the fuel injector driver circuit: A broken wire or a wire that is touching another component.
Faulty fuel injector: The injector itself may not be functioning correctly.
Problem with the Fuel Injector Driver (EDU): This is the electronic unit that controls the injectors.
Issues with the Powertrain Control Module (PCM/ECM): The main engine control computer may have a fault.
Low battery voltage: Can sometimes trigger the code, so check the charging system first.
Troubleshooting Steps
1. Check for other related codes:
This can provide more specific information about the problem.
2. Inspect the fuel injector wiring loom:
Look for any signs of damage, corrosion, or loose connections, especially around the affected engine bank.
3. Test the fuel injector circuit:
Using a multimeter or test light to check for continuity and proper voltage supply to the circuit components.
4. Check the fuel pump control module and relay:
These components are related to fuel delivery and can be a source of problems.
5. Consult a professional:
If you are unable to identify the issue or perform the necessary diagnostics, it's best to have the vehicle inspected by a qualified mechanic or ECU specialist.

Thank you Mark
The battery is a new one from halfords this year 03/25. Even though the model I've got is not a start and stop, will this be the correct battery. The battery must of been put on by previous owner,and maybe my problem was known to them around March time and they have tried putting a new battery on.
Itwasfrom halfords,so to be honest if they have fitted it on I've not much faith in them when it comes to vans.what battery would my van definitely need, I can put the battery thats on here if you need me to. Thaks

i don't know what battery it takes, there is a little catalogue on each section at Halfords that lists the specifications .. one for oils, one for brake fluids .. and i would imagine one for batteries.
To be honest i don't know much in relation to smart alternators and batteries and how they are matched, NOTE : the info about matching batteries that comes up on google is always specific to camper vans for some reason or other. think google thinks i have one .

i would not worry about the battery if its newish ... i think .. the info is for longevity and lifespan of a battery when being charged by a smart alternator - maybe shortened, by its wacky charging if its ther wrong type .

Concentrate on checking the earths, positives .. reading the voltages etc at rest and when running.
Noting ... from a little research i done last night .. a smart alternator cuts almost completely off when the battery is fully charged .. so may read something like 12.8 volts with engine running on occasions.
So when testing you can make sure it doesn't do this; by leaving the lights on for 10 mins with engine stopped to drain the battery .. then it will have to give its charge to the battery and not give you the confusing 12.8 volts info when you do the engine running test.
