Mot failure help

[Andy_con]

182 just failed it's mot

The one thats going to cause me issues is number 2.
Does anyone know the actual wire route from the engine bay to the rear cluster? I've dicking around with the rear cluster a number of times and ive never manged to fix the problem

 

[EZ Tutty]

It's usually the ground connection at one of the rear lights, unbolt it clean it.
Also check for corrosion on the rear light plug.

Done all that and problem not solved

The earth for these lamps comes up from front of vehicle to the lamp cluster and back off again to the front .

I'd be giving the cluster plugs new earths and it should sort it .
Run new wire to body inside boot car near to lamp .

I've done loads of them.

If you turn the ignition on and put all your lights on (so you can see the issue) and then grab the plug on the back of the light and half pull it off. It goes really tight just before it comes off completely. Leave it at the tight point.

If this cures the fault then your connections need 'adjusting' with a very small pick. You need to make the connection tighter.

Make sure you do this with the ignition off or you'll blow bulbs/fuses.

Done this before and it didn't make any difference

 

[Oggy997]

Better than mine!

 

[Andy_con]

my emission light is always coming on, on the dash. actual problem or new sensor?

Owner looks like susan boyle! lol

this one made me laugh

You're not doing it right then.

Sure, I'm sure it's rocket science? ;-)

You have to pinch the pins together also to aid a better/tighter connection to

This is what I was trying to say!

The earth doesn't go back to the front of the car either!

Rusty pins that need cleaned and pushed together will help a lot. It's pretty easy o sort

 

[Blerg]

I'd be splicing in a new earth like said. You'll have one feed down to the fog and b/l bulb ensure your getting 12v right through the plug and in the actual bulb holder and that water/rust isn't shorting the two. If you've got all that and it's good then a new earth or poor pins in the connector can be the only issue.

Some people seem to fit double filament bulbs in a single filament holder which seems to cause all sorts of problems. Worth a check but sounds to me like a saggy pin/earth fault.

Also the uhc module has its common fault with the indicators plus other central body electrical components which if you've ruled out the light plug, pins and earth then you may have to check down that route

 

[Andy_con]

Well if anyone in Essex is around to help have a look tomorrow feel free

:-(

The fog only comes on when breaking or when doing indicator on passenger side, not the drivers side.

If I remove the fog bulb from passengers side, the dash still lights up. If I remove whole cluster the fog on the dash still lights up. If I also remove whole cluster from drivers side, the fog on the dash doesn't light up.

Passengers side

 

[Andy_con]

Right slowly narrowing down.

Took all blues out of both sides and put hem back in, in order of bottom to top. The only time the issue occurs is when I put the top bulb in which I think is break.

Even even when I had indicators and fog bulbs in on both sides nothing. But as soon as I put either of the two top bulbs in the fault appears.

Really can't find an issue with the pins

 

[Andy_con]

Right managed to solve the issue with solder, o put a drop of solder on each pin and the problem has gone away.

How does this connector under the passenger seat come apart?

 

[Blerg]

Looks like the airbag harness? See where your thumb is there's two raised bits, slide a small flat head in there and release the tab if it's what I'm thinking

Also good diagnosis on the wiring plug, turned out its saggy pins

 

[Blerg]

 

[Andy_con]

Bing thanks, bit of tin foil in the pins and air bag light is off two faults down two to go

 

[Blerg]

Awesome! So just a set of pads and lambda. I'm assuming your capable of fitting the pads, just ensure the two spring clips on correctly and the piston is turned correctly to lock on the pad tab.
As for the lambda reading what did you get after the second idle, if it's bot too far out its probably a small exhaust blow. Post a picture of the emissions print out if you can

yep, pads are piss easy will sort them tomrorrow

as for the exhaust im booked into the garage for them to try find a hole. but the car is 10 years old and its the original exhaust and cat system, its never been changed. so wondering if its time

 

[Blerg]

Just hold your hand over the tailpipe briefly while it's running see if you van hear a hiss from a joint.

 

[rctempire]

Did you solve the earth issue?
There is an earth that runs from the clusters to the body.
Inside the car pull back the material each side of the wheel arch.
You'll see the earth. Take if off, clean it, back on, if you need to rub the car with sandpaper.
Fixed mine and other Clios with this.

yeah fixed cheers

 

[Andy_con]

garage has confirmed what I expected I need a new exhaust.

quote for centre section and two new back boxes with fitting 480.

where is a good place online to price chedk clio exhausts?

 

[Bluebeard]

eBay.

But in fairness you're probably better off getting the old one welded up and waiting for a secondhand stainless system to pop up on here.
£250, fit and forget.

 

[Andy_con]

New exhaust fitted and it's not solved the problem grrrr

 

[R3k1355]

Have you replaced the front lambda sensor, that is a prime suspect for causing emissions fails.

they are doing that today, just waiting for it to come in.

how much should this sensor be?

Bosch one is about £60 and 10 mins to fit.

 

[Andy_con]

ummm they are charging me 100 I think

trouble is, it doesn't have an MOT so I cant drive it around and its been off the road for 5 days now.

when you have a family (2 children) this isn't great

 

[Chrisgti6]

This is the reason why i always take my car for it's MOT 20 - 30 days before it runs out. At least that way even if it fails I can drive it until it's sorted. I know that doesn't help your situation but worth considering for next year.

£100 to supply and fit the Lambda is probably about right if they are using a Bosch part, but if they are fitting a 'universal' or none branded part then a) you are being charged too much and b) it'll proabbly fail again in time for next years MOT.

Also, was it them that suggested fitting a new exhaust would cure the problem? If so I think i'd be going elsewhere and asking for my money back. It sounds like they are throwing parts at it until they cure it, rather than diagnosing it properly.

To be fair the exhaust is the original one from new and the car is ten years old now. When I looked at the exhaust the other day it was pretty fucked so it was time for a new exhaust.
