Ad-blue gauge was reading low-
After some research it turns out the procedure for topping up the Ad-blue is farcical. In what design meeting was it decided that a tank that needs topping up should be hidden under the boot floor? Needing you to remove the boot trim and a section of the floor. Then when you do get to it access is so restricted you can’t pour the bloody stuff in!
I did however uncover a few other issues -
- Ad-blue gauge still reading empty, so further investigation required
- Trim clips and fixings missing from boot trim
- Rust around/under access flap
- Water ingress into boot
- Rounded nut on access flap
Quick overview of the procedure for getting to the ad-blue tank.
Tools required-
Nearside of the boot floor under the stowage trays.
Tools required-
- Cross head screwdriver
- 10mm spanner or socket
Nearside of the boot floor under the stowage trays.
Unscrew the 3 nuts and lift the access cover.
As the nuts looked corroded pretty bad I gave them a good soaking in WD40
Trying to fill at home is not advised here, as access is so restricted you can’t pour it without spilling it everywhere. I ended up using a funnel attached to a length of pipe. Not a great solution. Use a pump at a petrol station if you can.
As you can see there is water getting in somewhere, and there is a fair bit of tin rot.
Before putting everything back together I’ve cleaned away the loose rust with a wire brush.
Once clean I sprayed the area with hammarite to try and prevent it getting any worse.

I’ve had to reassemble using the rounded nut as I don’t have any tri lobe locking nuts to replace it with. I’ve filed it down so I can get a spanner on it. I’ll replace it at a later date.
