Just had the call...

[Guest Hooli]

My Gooona is deaded.

 

The UCH/Body Control Module is fooked. Dealer only part so not even worth asking for a price I suspect.

 

Anyone want it for parts? virtually new rear discs on it for starters & it's a good 80-85k engine (can't remember exactly).

 

Oh & it's got a bloody full tank of fuel!

I'll take the fuel please. Pop it in an jiffy bag and sent it to PO Box 9989, Portsmouth Po1 1AB

Which half of the UCH is dead?

 

 

The fuse section (right) is easily replacable.

 

 

The other side isn't as much, because it has all the immo data in it. But it should be, in theory, possible to get a donor unit and copy the data from the old one to the new one. Let me know if you're interested.

I love this place.  It's even possible here to salvage Renault electronics!  Who would have thought it?

Hi,
I don't know how the rest of the car is...

There are companies which can virginze a UCH from a scrapyard.

I'd also google to find it if you can't use the engine ecu + keycard + UCH from a scrap vehicle...
I did that with a 2000 laguna 1 with an engine ecu full of salty water... Admittedly, in a Lag2 there might be more components coded directly to the UCH - for example the electronic steering lock. The card reader, however, is not.

It also codes new Chinese keycards which can be bought for 30 quid and look identical to those from Renault for 120...

That's true and a good call, a ECU set will do the trick - probably the easiest and quickest option if the UCH is dead, dead. I've seen ones much cheaper than that though. Just make sure that the steering column bolt is unlocked before trying to undo it - its also a left-handed thread.

 

A complete set is: ECU, UCH, keycard and steering lock. If you can get the first 3, then the steering lock box is mega easy to virgin (write FF to the EEPROM) and will code itself to the code when put with a ECU+UCH that match themselves up.

 

Renault say you can't recode from one car to another, once they have been programmed in once. The immo data is stored in the main controller IC (rather than a separate chip). However I have got some data on how to read out the eeprom data from the UCH. Never done it before, so only in theory it works. If it didn't, the other option is to desolder the main chip from one and solder it to a new working one.

 

But a ECU set still will be the easiest option to do - providing it works enough to get the steering lock disengaged.

[SiC]

But check to see which half is damaged. IIRC, from your previous pictures, it appeared to be mostly the fusebox part that got wet and suffered the corrosion?

[SiC]

IIRC yours is a 1.9 dci?

If you swap the fusebox half, double check the jumpers/metal links on top are in the correct location.

[Bren]

Lots of useful info regarding this.

 

What I will say is this - thank fuck Renault never got involved in aerospace or the space programme.

 

We would be buried under aluminium.

[Dave_Q]

If the ecu set for a pez Gooner is worth double the retail value of the car, I'm retiring to become a Goona_Breaker.

[Guest Hooli]

It's a 1.8 petrol.

 

Diagnostics couldn't contact the UCH so I assume it's the circuit board part? Will ask the garage who did the diagnostics when I pay them for that tonight.

 

Ways to fix sound interesting, pissed off with the money wasted so far & feel like scrapping it is pouring money down the drain. Tell me more....

 

 

ECU kit doesn't look too expensive & the steering lock is laying in the passenger footwell as I removed it so as to be able to tow it to the garage. I'll have a good look on ebay later.

 

Cheers for the ideas so far guys.

Most of the circuit board section is powered off the fusebox part. Main feeds come into the fusebox first. When you pulled the UCH apart last time, was the circuit board part (black box) wet at all?

[Guest Hooli]

The circuit board was dipping when I last removed it.

 

Been to the garage to pay them tonight, will collect the heap monday.

 

The circuit board in the UCH has visible damage that I'd missed when I looked at it, so it is that that's dead. I'll look for a cheaper ECU set than the one above, but tbh £120 doesn't seem to bad to fix it in my head.

 

If I sent you the dead UCH SiC what sort of timescale do you think you could copy the data over? I realise you haven't done it before etc. I might well go that way if it wouldn't take too long for you to try your idea out.  I don't need the car everyday, but I am sick if seeing it parked up dead.

I reckon it'll make you a very poor man as in two years' time they'll all have grenaded themselves to extinction, taking your market with them.

[SiC]

But 8 years time they'll be a classic and such parts will be worth ££££.

 

Probably a market for keeping current modern dead car electric boxes and storing them for 10-20 years. When they become classics, these parts will be like gold dust and are critical to make the cars work properly.

Meanwhile endure a divorce when your love of collecting mk3 Mondeo starter motors gets out of hand.

[Pillock]

You can probably be sure of a BBC4 documentary, exploring the life of a man who collected ECUs, carefully stored them and waited for the phone to ring. Every so often he would catalogue them into an Excel spreadsheet, dust them and research which types are becoming hard to obtain.

Waiting for his fortune to be made, supplying parts to car enthusiasts where the manufacturers have long since moved on and abandoned them. 

 

Waiting.

Yep ECU transponder and key set. Don't take up much room in the loft and should be a good addition to your pension plan...I just wish I had squirrelled away a few sets of MK1 escort bumpers when they were a couple of quid a set from any scrapyard you went to...

SiC do you want the broken UCH for testing your theory on?
