 Just got a call from my friend to tell me he noticed my lights were stuck on as I drove off.

So without going and dismantling the rear of the car is the rear tailgate loom issue likely to be the culprit or is there another idea someone has for me to check?

Just typical car seems to be bringing up a few issues over the last few days.

Depollution fault x 2 + engine management failure after the depollution fault once.

Went into limp when this happened. Now not there any more but the car feels flat especially at the top end. Just seems to stop pulling once it gets to 5500rpm. Which in a 180 considering power is up at 7000rpm is a problem.

Hoping I can get it hooked up to diagnostics at some point soon. But just a bit worried about it all now. If this is going to be expensive or not. As it also needs new rear brakes and I think the exhaust is on its last legs too.

 As you haven't had the tailgate recall done, that should be first port of call.

Depollution fault on a petrol...isn't this normally coil pack?

Exhaust on last legs? I thought you had a custom stainless steel job fitted? Stainless steel exhaust should be 5 year warranty at least.

 No mine is still on the original OEM system. Which for a 180 is doing well with it being 6 years old according to the build date.

 Just reverse lights Tom? Could be either loom or reverse switch on the gearbox as some quick guesses.

I'd guess if it's the switch on the gearbox you'll also get the reverse sensors active... if your's work with your headunit.

And expect your delivery on tuesday

 Sensors are functioning as normal. Just the lights that are stuck on.

I was thinking loom, just finding out where exactly it has the problem is the fun bit. Going to check the obvious tailgate section tomorrow when I have some decent light.

And cheers Scott will get it sent back to you ASAP.

 Well just been and checked my car doesn't fall under the correct VIN range for he recall. But also need to go back out and try getting the rubber boot off. The thing just doesn't seem to want to move.

You need to remove the left side boot trim and unclip the wiring to give you some slack at the rubber sleeve.

I had the lights stuck on in reverse on my c4 vtr+ and it was the switch on the gear box. i found out on here that it can be a common problem. I removed the switch from the gear box and replaced with a new one from dealer which are now a different type and problem solved. Think it was about £6.00.

 Ok went out to it earlier today and I think it is now likely to be the reverse switch.

Obviously searching for reverse switch on site brings up quite a lot of results. So is there a part number and a guide or a rough idea of what I need to do to change it?

Looks like:
C4 3 DOOR SALOON 2.0 i 16v 180
(19) 2257.59 SWITCH-REVERSE £8.10 + VAT @ 20% = £9.72





If you PM me your VIN, I can nail it down.

 You would've thought that it would also trip the reverse sensors too wouldn't you?
Is that what Lexia is saying anyway Tom?

 Tripping the sensors now Scott. Not hooked up lexia yet. Arrived yesterday jut before I was going to the hospital to see my mum. Too late to try when I got home.

And today I just felt unwell so not tried yet.

 Yes, Lexia is awful!

I swear it just likes to crash for fun it will crash doing things it has done previously with no issues following the exact same procedure. It just is a horrible bit of software. Also not very intuitive. With me asking for issues with the engine it brings up that my drivers door module has a lighting error. Yes because that is related to the engine!

No wonder Citroën charge so much for diagnostic hook up it just feeds you a ridiculous amount of pointless info. That is if it does not crash or freeze up half way through.
