Alternative to Crashdata

Generally the repair ECUs. A cheaper alternative to replacements which is what most garages will do.
I've not personally used, so no personal reccommendation

I used Crashdata in the end. Very quick service. Posted 2pm Tuesday and delivered back to me by 11am Thursday.
The analysis that came back was everything ok but battery at 14.4v. Battery outside of spec both high and low power. I called them to ask for advice and got a particularly unhelpful and fairly brusque woman tell me to get my battery checked. I explained it is only one year old and asked what might cause the issue but she was not helpful and would not let me speak to anyone technical.
So my question is given that the MH is pretty much permanently on EHU could this cause a spike in the battery voltage?
Also should I disconnect the EHU for a period before starting the engine?

Just had the same issue but my voltage spike was 14.2 according to CTD.
I thought up to 14.4 was normal when the alternator was engaged.
sounds like a common fault, just hope it’s not one that raises its head to often.

I have read that the spikes are caused by having a low battery, not sure how that works to be honest. Also It has been spoken about on here to turn the ignition on and wait a while before trying to start.
Even though it is quite new your starter battery might be faulty; or, one of its terminal clamps was a bit loose when the event happened.
I had a similar printout from CrashData. In my case the most likely cause was 4 year old battery, not holding charge too well, in a van that had been undriven for 10 days. The voltage must have dropped too far even though the engine seemed to start OK. Later I did a test to see if I could replicate what happened. Nominal voltage 12.7v so that seemed OK. The glow plugs and starter motor load caused the battery voltage to drop to below 10v before the engine started. Then it went up to 14.2v when the alternator kicked in. Maybe that swing in the voltage caused the airbag ECU to have a head fit. After CrashData repaired the ECU, I decided to replace the old battery anyway.
I can't comment on whether you should disconnect the EHU before starting the engine as a matter of good practice. I always disconnect it and put the EHU lead away first, so there is certainly a delay of 10 minutes or longer that would allow the battery voltage to fall from about 13.2v although perhaps still a bit above 12.7v by the time the starter motor is engaged. As a belt-and-braces approach I like to put the van on EHU for about 3 or 4 hours to ensure that the starter battery is fully charged, at least the day before I am going to drive the van again.
