Weird faults

Hi all, my TD5 has been acting up recently, and things keep getting weirder.

So I replaced my battery a year ago with a specified Bosch unit. Recently had the Bosch go dead and read only 7.75v. Charged it up battery held fine at 12.6 started. Took it in a 70 mile trip to work, then back no issues with it until I had to use the boost box of shame to get it turn over again.

Alternator output ok at 14.5v engine running. Culprit for the drain is most likely to be either be my DashCam triggering and recording (what drained the last battery which seems to be ok when I charged it up now) or possibly a vehicle tracker that I had for my old employer.

Strangely enough at the fuel station today and tried to start up and single clicks the first couple of attempts in ignition 2. Gave it a couple of seconds and turned over normally.

It’s also Exacerbated what I thought was a little quirk. After long runs I’ll pull up and park.
Start up again and usually at the first dead stop I’ll do. Car looses power and stalls. Am I looking at a possible ECU fault or maybe MAF going up the creek?

Anyone had any similar issues? I'm on IG: https://www.instagram.com/osloblue42/

How irritating and frustrating. I have been there with Miffy.

Low hanging fruit first.

This sounds like the starter solenoid needs a refurb kit. It is easy to do but the starter has to come out on to a bench.

Next. Earths, always the earths. Go around and double check that all the body earths are clean and it is worth smearing some contact grease over them to maintain the good connection.

Now for the not so easy news.

This sounds very much like your topside switch in the ECU is on the way out. The only solution is a refurb or replacement ECU I am afraid.

Do you have a nano com or other to check for fault codes?

Yes think the starters probably gone owing to trying to crank on low voltage/boost voltage to start. I had a new nippon denso fitted five years ago and that was burnt out to the point that the replacing the solonoid was no longer an option.

Yes the symptoms fit. Luckily got a little money set aside to spend on restoration and refurbishment this year, luckily empire tuning is just up the roman road in colly and they can deal with top switch faults.

I have a multimeter but don't think its worth probably ruining the rest of my ECU to test the capacitors.

What i don't get is i've had the symptoms for over five years and getting the car to stall out always requires long runs of hard motorway driving... Maybe experienced this half a dozen times in the past five years. At least one in 2018, then maybe twice a year 2019-2022 but have had it three times in the past six months.

I guess i'm just a little worried i'll stall out and get stuck.

Thanks! I'm on IG: https://www.instagram.com/osloblue42/

disconnect all items you added like the tracker etc for the moment, and then check clean all earths. My rover metro was having some right old trouble starting, turned out it was an earth on the gear box had gone bad. The simple things 1st before you go into the major stuff, like ECUs.

Oh to have just the one Land Rover garage close by

It'd be like having beer on tap
