Midway through fitting Uch and ecu, need help pleeeaase!

[fletch8]

Right I've swapped over my key fob, ecu and Uch, car goes to fire up but won't. Has the I initial noise but then no "bang"

Any ideas?

Please Thank you

Immobisiler light go out?

 

[fletch8]

Not to worry guys! Left it a few minutes and dannnaaaaahhhh we have lift off! Everythings working as it should (touch wood) no more flickering lights no more non functioning windows, no more peering through wet glass when my wipers don't work, it's fixed!!! Woohoooo!!

Usually you need to lock/unlock first mate, then it works.

 

[fletch8]

That must of been it, my face dropped when it wouldn't work and I'd put it all together!

The feeling of doing it yourself is brilliant as well!

Problem with my cruise control and ESP, is this because the Uch is off an 02 and mines an 03?

Yup, need someone with clip to turn them on. (I can do it if you're anywhere near)

 

[fletch8]

Im on the Wirral on merseyside. A clip to turn it on you say? Straight forward enough to do for someone?

If the option is there on the uch it's a 5 min job.

"clip" being the renault programming computer, not an actual clip

This is why I still don't "get" swapping the whole lot just for a faulty UCH, its not like they're even that expensive any more.

Huh? They are £300 new from Renault, and that's without coding. I know i'd rather go for the second hand option.

£258 last time I checked, they were down to £150 at one point too. I'd rather pay that for a proper job and have everything fixed and working as it should rather than "bodge" it swapping old bits over a loosing feature. Plus the vin numbers on the ecu and the uch won't match the shell now either (not overly important).

Guess its just a difference of opinion, I don't cut corners trying to save a few bob. If a jobs worth doing its worth doing right imo.

It explains a lot of the rough older RS's I see these days though.

Fair enough mate. It's a shame UCH units can't be reprogrammed If they were under £200 it's not an issue. Although, lots of faults some times point to the UCH, when if fact it's nothing to do with it. So a waste of money really.
The only problem I could see is if people buy the incorrect UCH for the car.ie. N2 or N3. It should be plug and play otherwise. I see what you're saying though. Plus most people who do these changes might not realise that there are different UCH with different parametres on. Just an expensive black box with a few relays attached

Price was 268 for a new Uch then 140 to fit it, I got it all for £80 and did it myself. Once cruise control and ESP is set up on it it'll be as good as going to Renault. Both n3 units too. Anything I can't do or major I don't and won't do
