D2 2.8 No Start Issue
Car wont start!
In the 9 years I have had this car (on the road and off) it has never once had an issue starting, until today. OK, wash time. Jumped in, Started fine for positioning in the driveway for washing. Floyd kicked in on the CD so happy days. Pre-wash, power wash and rinse, Snow foam (Bilt Hamber), 10-15 min soak, power wash off. All as usual. Left for 30 mins, Jumped in. Started up. Re positioned in the driveway. Whilst sat and idling and just before turning off, no Floyd, sound system off, battery warning on, airbag warning light on, ABS warning on, engine starts idling like a pig, electric windows moving but extremely slowly. HVAC still running although a bit haphazard. Hmmm water ingress! Just about to turn off to investigate and the engine switched up to idle at approx 1200 rpm and running smooth, but no response to the peddle. Must be water Turned off. Checked: HVAC drain - Nope OK. Checked passenger footwell, dry. Checked below Botangs for any water seepage, none. Relays and electrics in footwell all dry. Checked battery (yes its a Yuasa) but came back healthy. Checked engine and gearbox ECU, dry. Tried starting up again and nothing Not checked: Fuses. Junction box offside wheel area - could it be this? - Im in no inclination to be scrabbling under the car today. Or any other suggestions please.

it could be the alternator junction box under driver side front wheel arch yes.
whats the battery voltage whilst the engine is off? whats the charging current with engine on? how much fuel do you have? does your alternator have a freewheel clutch? mine failed and spun bot ways freely not charging the car.. Last edited by Ronin; 31st October 2021 at 03:06 PM. |

It's natural to assume that your cleaning has triggered this and look for related areas of disturbance, but maybe not?
The symptoms while running sound very weird, beyond my pay grade to say what might cause that, but I'd go back to basics with a multimeter: Check battery (you imply that seems OK) and the connections to it. Then move on the circuits that are live all the time and test voltages. Brake lights spring to mind there - I'm pretty sure they're always live. Not sure about cigar lighters? Remote locking is one obviously, does that work? Then measure other circuits, starting at the fuse boxes or under the front passengers feet. Hopefully someone with a deeper understanding will be along soon to point you more precisely. Just not starting can have many causes.

Cannot measure charging voltage (engine not running) Fuel level 70% full (always keep it over half when standing for long periods) Not a clue about the alternator. I have some time tomorrow, weather permitting, and will check junction box and alternator along with anything else I can glean. I'm convinced I have stuffed the junction box when vigorously spraying with my jet wash or just hoping it's a quick fix.

The junction box should be behind a cover, and even if that's missing you can't spray it directly with the wheel on. There is a 2-pin connector clipped to the side of the junction box which carries the starter solenoid and alternator field connections. If that is loose or corroded then that could cause a no-start / no-charge situation.
It does sound like a low voltage issue, and tbh I wouldn't trust the Yuasa as far as I can throw it. Their usual failure mode is to test just fine but be unable to supply decent current for starting. Does anything happen at all when you try to start it? Dimming dash lights etc? Its not uncommon for the F125 to prevent starting, but that wouldn't come with all the other symptoms. |

I'd put the battery on charge overnight (if you can) and see how things are tomorrow.

Just checked again and I think the battery has pooped itself. Good voltage but not enough cranking power, chattering starter and flashing dash lights.. but i will check the connections on the box first before i condemn it. I had a yuasa on my other D2 and that was only 3 years old and it just gave up.. Guess it's a Bosch going forward.

Varta and Bosch are the same batteries, but the label on the Varta appears to be £10 or so cheaper
