Dead Laguna 2

[Guest Hooli]

Help!

 

New member here hoping you lot of shite'sperts will know what's wrong with my damn Renault.

 

It's a 2001 Laguna 1.8 and the problem is...

 

All the dash lights are on all the time, it won't start, just spins on the starter. The dash lights are on even when the car is locked & key out etc. There was a buzzing like a flickering relay from the throttle body but that'd gone now the battery is almost flat.

 

i've found the driver's footwell is soaking, so I'm suspecting it's the sunroof drains (sunroof is/was gaffer taped up but some has come off) or some other leak is soaking the electrics behind the dash. I believe there is a control unit in that area that controls just about everything & I can't disconnect it or it'll need reprogramming?

 

How do I use the emergency key that pulls out of the keycard? If I take the battery off to charge the car then I can't lock it without knowing where the secret keyhole is.

 

I've found a free radio code generator for my phone, handy that as the radio code didn't come with the car.

 

Oh & this is where I say 'great forum, love the humour & knowledge' to make you all like me & give useful answers right?

I wouldn't have a clue, but have you tried removing the battery and let the car dry out for a day or two?

Sentence rearranged for clarity

 

It sounds like water might have got into an ECU to me, but I know as little as possible about French cars so that might not be helpful at all. I'm sure one of our Renner fondlers will be along shortly to give you proper advice & collegial sympathy though. Best of luck with it!

Emergency key hole is accessed by popping off the cap on the door handle. Should be a little indentation underneath, can't remember if it's both or passenger only.

 

That will give you access to open the door so you can pour petrol on the seats and light it. I honestly can't think of much else to do with a Laguna 2 with electrical faults.

[dollywobbler]

Passenger door only I think.

What was it James Brown shouted repeatedly on Sex Machine?

[overrun]

If bridging the ungrateful ferrous bastard is too much bother, just recharge the battery and let nature take its course.

A natural fire is surely imminent.

[Pete-M]

Laguna electrics make a Zafira look about as flammable as granite.

Sounds like water has got in the UCH (Body Control Module). It lives attached to the fusebox in the interior. Deattach the battery, remove the UCH, take the lid off and give it a good dry, use isopropyl alcohol (maplins) to give it a good clean. Reverse to reassemble.

 

Got a sunroof? If so probably blocked drains that cause it to leak through.

 

Wet body control modules isnt a thing that is Renault only. Audi A4/Passat/etc are notorious for their scuttle drains becoming blocked, water filling up and eventually going in thru the cabin air intake. Gives the blower motor a good soaking and the BCM nearby.

[cort16]

Shite battery, bad earth, wiring made out of spaghetti hoops?

[scaryoldcortina]

Welcome to the club....

It does sound like a drenched BCM causing the trouble - there is an access flap on the end of the dashboard (near the driver's door hinges) where you can peer in and despair. Actually getting the thing out of there is another issue entirely!

[SiC]

Also be aware that they hold the immobiliser information, along with the engine ECU. So you can't just swap the part out with a second hand one, without copying that immo data across.

Ah... the Godfather of Shite...

 

[Guest Hooli]

Lol thanks for the welcome guys.

 

I have to agree about not liking french cars, I'd never pay for one myself either. It's oddly decent to drive though, I was beginning to think they weren't too bad until this.

 

Batt is out n on charge. Shame I can't lock the drivers door now, lucky we live in a quiet place. Plan is to take that end of the dash apart n dry it all out. Might even look for the sunroof drains n clear them out.

 

Guess the fact you can never drive these cars is why insurance is so cheap? Can't crash it when it doesn't move after all.

[Partridge]

My Pug 605 did a similar thing (sans le leakage et le water dans le footwelle). As Cavcraft suggested, try disconnecting the battery and see what it does. I disconnected mine and came back and hour later to re-connect it and it whooshed into life. I'd not want to leave it much longer though, as can't disconnected a battery for more than a few hours sometimes balls a car up? At least it does to Rover 800s.

[dollywobbler]

I would like to point out that not all French cars have terrible electrics. I thought they did, but Renault really have taken things to a whole new level.

[Twiggy]

I saw a Laguna proceeding rapidly up the M5 on Tuesday - is this a record ?

 

No, it wasn`t being towed, nor was it on the back of a truck.

 

It was under its own power.

 

I think.

 

It was going downhill at the time though.

[SiC]

I saw a Laguna proceeding rapidly up the M5 on Tuesday - is this a record ?

Rapidly, because the owner wanted to get to their destination quickly before it conked out again?

[Guest Hooli]

Well boys n girls, I have news.

 

I've charged the battery and the beast lives today. Still got a few dash lights on all the time so I've left the battery off and as much dashboard apart as I can. That along with a good dose of wd40 to dry it out.

Looks like the water gets in near the top of the dash, highest wet bit I can find is the heater tube to the vent. Looks like a two day job yo get the dash out n back so I'm trying to find an easier way to work out where the leak is. I'm guessing a rubber grommet around wiring or similar.

 

I was tempted to dry it with fire, but petrol n matches cost too much.

Hi,

my brother got a free Laguna 1.6 that ECU and UCH replaced due to water damage coming from the sunroof. I recommend you to do this:

Meanwhile also clean out the space behind the front wheel. It will be full of dirt.

If all else fails you could always try and verify the 5* Euro NCAP rating with a local concrete bollard.

Real cars don't have modules.

 

I bet that's helpful...

[SiC]

Real cars don't have modules.

 

I bet that's helpful...

Does that mean this is a proper car then?

[trigger]

I bet that would get you down to the end of the street quicker than a Laguna.

[Junkman]

I bet that would get you down to the end of the street, which isn't guaranteed with a Laguna.

[chaseracer]

This is a better way of sorting out a Laguna's problems...

Ah, the Laguna Problem.

[Junkman]

Is the Laguna the new Autoshite Vauxhall?
