Clutch replaced but Immobiliser light solid and wont start, Help

[Leo182]

Any ideas? Garage has put a new clutch in, goes to start it, cranks but wont start red immobiliser light is solid, any ideas??

Earth I would guess, there are two straps that need to be removed to move the box and its easy to refit them wrong or forget.

Ok, Cheers SharpyClio do you know where they are so I can point the mechanic in the right direction!

 

[SharpyClio]

Sorry, that would she’s helped. So there’s one strap in the end of the box that goes to the chassis.

For some reason I had it in my head this attached to the tie strap that’s a bit further back but I was wrong.

The other is on the back of the box, just up from where the near side driveshaft goes into the box. Easy to forget.

 

[Leo182]

Hes checked these and both are on, anything else it could be??

 

[SharpyClio]

Get him to double check all the wiring, its likely that something hasn't been reconnected properly, I did my clutch and gearbox last week and I am trying to remember all the things I disconnected. Some of them wouldn't cause an issue but some might, easiest way is to double check everything again, might even need to disconnect and reconnect things to try and make sure.

 

[Leo182]

Right, hes triple checked the earth straps and everything he says but still the same, he reckons its the immobiliser itself!
Hes at a loss, any ideas anyone?

 

[Krarl]

Probably disturbed the white plug in the engine bay fusebox when removing the battery

Tell him to stop being a f**king chopper and actually fix something and be a mechanic. Useless c**t

 

[Louis]

How much did you pay him?

Not payed him yet! at this fackin rate he'll be paying me!!

 

[Leo182]

Ok, so I am getting a checklist of all possible issues in order to solve this and so far I have these.

1. Earths
2. Fuses/Relays
3. Crank Sensor bolt
4. New battery/2nd key fob
5. Broken wire.

Anything I've missed bearing in mind it was ok when it went in to have the new clutch fitted.

It does crank like I said but the immob light is solid.

 

[Louis]

Put the key in the ignition. Lock it and unlock it on the fob.

Lock it and unlock it on the button in the car.

Turn the key all the way round to just before cranking and leave it there for 5 minutes. Then go back, and do the same again but holding the central locking button.

Then try crank it.

 

[Leo182]

Update.

Mechanic has tried all the above and more, he's a decent guy been really good but this has him beaten, is there anything ANYTHING that I can try??

Its doing my head in tbh now, hes had it a week!

Replace the ECU and UCH.

I have one for sale.

Get him to check this one again. I would put money he's not looked properly.

Out of interest, any idea why that would fail in this instance? running out of ideas so willing to give it a go!

He is adamant he has, checked it twice over he tells me!

 

[Leo182]

Another mechanic mentioned it could be a broken bit on the flywheel as it needs that bit to start the car, he has been know to be wrong in the past though!

 

[loggyboy]

He should have been checking the basics like TDC/crankshaft sensor (thats the sensor on the fly wheel). There are quite a few little things that can cause this.

 

[Rojer]

What diagnostic tool has he got? Does it have any codes?

They can just fail and it could be unrelated to the work done.

I'm not saying this is your fix though.

 

[Leo182]

Shows no codes apparently, not sure what he uses but it wont be a clip.

Said hes checked that, even replaced the crank sensor!

 

[Leo182]

Can low fuel stop it starting over? it chugs like it wants too start, light was on when I took it in

 

[Louis]

Not if the immob light isn't going off.

 

[Rojer]

@Brigsy might be able to help.

 

[Mr Trailer Man]

He's obviously done/not done something when the box has been off.

Going to be hard to fix over the internet if he's said he's checked everything.

How come you didn't go to Birchdown like you normally do?

Stupidly thought swapping a clutch over will be fine for someone who basically specialises in them, in hindsight and all that 😢

When my key was dying, I used to have issues starting the car unless I held down the button on the fob while starting the ignition. Sounds a bit wonky but it helped me start it for about 8 months until the key finally died and I had to go to Renault for a new one.

 

[Louis]

Can try leaving the battery disconnected for a while

I've tried brand new batteries in both fobs but no nothing.

Battery is currently charging off the car.

It’s not the batteries that were the issue, it’s the key itself. See if my method works, it’s easy enough to try. Otherwise it’s off to Renault for a new key, hopefully they still make them.

He's tried that with what I sent over though. It's more like uch, ecu and decoder ring at this point but who knows.

 

[Mr Trailer Man]

Be absolute s**t luck if it drove in there for a clutch and now suddenly the uch/key has given up.

Well it didn't drive in but the car started fine but knowing my luck it will be that.

I'll probably get a auto electrician to take a look before I play parts darts

 

[Leo182]

Back again! Would a Renault Clip bring up a code? he's using a Snapon which doesn't bring any codes up.

 

[Brigsy]

Its immob related defo if solid red light, earth or fusebox/loom wiring.

If hes pissing about with crank sensors etc hes way off. You need clip to show immob stuff to check key is working.

Check the relays in fusebox have mot been disturbed when removing/refitting battery, as the cover can knock the small relays out of place.

Also not uncommon for these to have a hissy fit on immob when batt off. Id try key in ign for a few mins with ign on.

Failing that i reckon broke wire in loom.

 

[Leo182]

Faults on his code reader, does this help? the guy is an absolute legend, he's still on it now to try and sort it!

 

[Brigsy]

At a guess Df236 listed, even though not currently active is suggesting there is or was a problem with the injection locking relay in the fusebox or other power or ground issue.
