my 2002/03 diesel range rover wont switch off, its very hot under the bonnet, and there is noise coming from either the ECU, environmental box, or glow plug relay, three hours after parking for the night.

it's been using a lot of coolant, needing a litre a day the last two weeks,

does anyone have any suggestions?

cheers

1 - problematic ECU - get it on diagnostics, check ECU box for any dampness

1 - you have a coolant leak - fix it ! Don't keep filling it up. Can you physically see the coolant leaking ?

It's booked into landrover on Monday for the coolant issue, they are too full to see it before then, and no I can't see the leak, I had it at a local garage earlier this week and they said it was either a cracked cylinder or head gasket issue and I was as well to replace the engine. So I thought I'd get a second opinion from LR,

The ECU issue, I was just worried about it exploding on the driveway

, should I disconnect the battery? Thanks for replying

Oh right, that's not good news is it !

Sounds expensive ! Lol

That might be a good idea to disconnect until the garage takes a look at it

That's a standard rip off garage response. Just as likely to be a leaking RAD or header tank if it's running OK.

He said he 'can't' see the leak, :brick:

I know its a differant car but my wifes vectra was running fine but useing about half pint of cooant a day 40mile round trip. Couldent "see" a leak then eather. Turned out it was leaking directly onto the exhaust manifold then evaporating before making it to the ground
However as you clearly have a serious electrical problem at the same time i would think its leaking into the cabin somewere (possably the heater matrix) then the becm got wet
Were is the becm on a l322

a litre a day, into the cabin,? Are your feet wet maggie, is your screen misting up?

myfirstl322 · Aug 24, 2013

Is there water in the oil, have you had expansion tank tested for C02?

myfirstl322 · Aug 24, 2013

White smoke from exhaust?

I know a liter is alot but sounds logical

The bcu on the l322 is under the passenger seat. Unlikely to get wet from a coolant leak. The hoses at the rear of the engine often leak as they are unseen and neglected, they leak directly onto the gearbox so it evaporates before it hits the deck

TCubed · Aug 24, 2013

Do you get any white smoke from the exhausts?

myfirstl322 · Aug 24, 2013

i just think it is important to elimate head gasket first and foremost, quite simply have a garage stick their exhaust gas analyser into header tank, check oil for contamination, pressure test coolant system, and at least check exhaust visually for white steam.....

If that shows nothing then move backwards......

and onto a flatbed:behindsofa:

Not heard of HGF or cracked heads on this engine.

Maggie. If the garage you took it too suggests that the engine should be replaced because they 'suspect' head gasket failure, then take it too another garage. End of.

I agree, lazy ####s

+1 once a garage "thinks" its something even if hes wrong he is unlikly to change his mind.
Get a second and even third and dont tell any of them what the other garages have told you cos then thell just agree

myfirstl322 · Aug 24, 2013

It is vital to get head gasket ( or crack in head) diagnosed properly, pressure test procedure, CO2 in coolant, exhaust smoke, also, if thermostat failed closed, this may have been the contributing factor to the whole fiasco. It won't fix itself, alas..
