Frigging Tailgate!!

So I offered to help my mate out who needed a fridge freezer as his broke. (Necessary journey)
I went to pick it up on my way to work to keep journeys to a minimum etc etc.

I'd spent the morning washing, vac'ing and cleaning the motor, along with an oil and filter change.

The tailgate was working fine when I removed my dog boxes (yes you've probably guessed it Crying or Very sad ), but when I pull onto the driveway of the property I'm collecting the fridge freezer from it doesn't want to know! Frigging motors know when to pack up don't they.

Fortunately an integrated fridge freezer will just fit through the rear doors of a disco 4 and with some shuffling and lying down of the front seats, it'll fit fine. Getting it out was much the same.

Anyway, having spent my break reading post on tailgate woes, I have a couple of questions...

Is there an internal button push method for the D4? Like the lock/unlock button push on the D3?

Is the carpeted panel removal just for the lower tailgate or does that apply for the glass upper tailgate?

Under the rear near side of the vehicle there's a big wiring connector. What's that for and how do I stop it getting wet? Surely water in there will cause issues? Just wondering if me jet washing has got that wet and that affected the wiring to the boot latch?

Thanks in advance for any help given.

Can you hear the actuator operating when you press the handle or silence?

Have you tried the Tailgate release on the fob?

The actuator for the top tailgate release lives in the lower tailgate so yes it's the carpet part needs removing to replace if it turns out to be the actuator.

If your talking about the two big plugs on the chassis behind the N/S rear wheel, I've never heard of tailgate problems caused by these plugs, mainly Can bus and handbrake problems I think.

As a side note with motors giving up, last year my rear door motor decided to give up whilst having its MOT and consequently failed

so quick change of actuator and back to MOT station , quick inspection of door and passed

Hope u get it all sorted out

Hi,

I can hear the actuator when I press the fob and the handle. I just don't get the 'pop' from the boot opening and when I press either and pull the door it stays shut.

To top it off, I then couldn't lock the car as it kept beeping to say the tailgate was open. Rolling Eyes

Got home this morning after a night shift and fortunately it locked. Still can't open the boot though.

I'm guessing something's sheared off somewhere.

When I fitted the reversing camera, there was a bit of corrosion around the screws that hold the housing for the camera and door handle on, so maybe water has got in and over time broken the mechanism.

Anyone able to list part numbers and pictures so I can order the right bits once I've got it off?

Or point me to a place I can find them?

Cheers all. Thumbs Up

Thanks for the links. Thumbs Up

I opened the tailgate today following the guide. Easy enough to do.

The cable and L shaped end piece are in tact. Pressing the boot release on the fob showed the actuator moving a tiny amount but not enough to move the cable, so I'm guessing the actuator itself is broken.

I'll order a replacement this evening. Is it worth changing that L shaped bit too to prevent failure later on? I'm going to fit an internal release so I don't have to fiddle about again if it fails.

Thanks again for the help folks. Bow down

Glad it helped Thumbs Up

Must admit it certainly wouldn’t hurt thatS for sure considering the hassle u would have to go through if it locked shut

Hope it’s all an easy fix mate

It all came apart easier than expected. I found the easiest place to pop the carpet out was where the plastic trim slopes down on that iconic boot shape. hardest part was popping the actuator wire out of the housing so I could pull the cable and open the tailgate.

It's all stirped down ready to be replaced and I've managed to shut the tailgate and lock the car. I just have to lean in and pull the cable to open the boot for now.

Question is.... Genuine or Aftermarket part? Saving of £15 plus vat. I'm normally a genuine parts kinda guy, but feel slightly robbed by a £60 door actuator. Shocked

Amazing how essentially the same part, albeit a slightly modified end, can be so much cheaper.

All fitted yesterday and I've added a length of paracord as an emergency release, tucked up out of the way but easier to get to than popping off the boot carpet. Especially if I have the dog crates in there!

Next step, the oil drain mod.

Cheers

I’ve just got my first disco (2010 d4) home and think I have the same issue. I did notice corrosion on the 2 wires where the upper tailgate hinges to the body. Can anyone tell me if these are involved in the opening mechanism or are they just the heated screen? Thanks in advance.

Hi,

I'm not certain, but I think the wires for controlling the tailgate actuators are both in the lower tailgate. I think the wires you can see from the roof to the upper tailgate are for the reversing camera, brake light, number plate lights, window wash etc.

I'm sure someone will be along soon to confirm.

If yours is a 2010, you may have the emergency boot release by pressing the lock and unlock buttons on the dash at the same time.

Anyway, welcome to Disco ownership. Thumbs Up

The general theme is any issues are usually "It's a common problem", but the good thinkg is there's a wealth of knowledge on here and nothing beats a disco. 8)
