Hi. Can anybody help me with how to remove the front bumper on mine? I have had a look online for a video with no success. Mine comes with parking sensors. Many thanks.

You need to remove the grille first the bolts are obvious on the front rail. Disconnect Parktronic connector under RH. Undo two bolts on either side of engine bay on chassis. Undo four bolts facing facing you top and bottom in grille opening. Easier with help.

As weell as above.

There are 2 bolts up into the plastic supports that are seen from below the bumper.
Thes suports break easily if the van is bumped, I've lost a couple by catching raised kerbs while parking forwards in.
If memory serves about £16 a pair, they are handed, one takes your temp sensor.

I'm pretty sure you will find a torx screw on each side in the wheel arch.
At the rear of the bumper, at the top of the bumper itself and hidden behind the wheel arch liner. The liner needs to be forced 'open' and then better seen with a torch.
These often break the bumper if the bumper if abused, or bumped.

The whole bumper slides forward on sliders. As said easier with help so it doesn't fall as it passes the sliders.
I've a rubber mat I place below and ease one side off while the other side is still supported a little.

Many thanks Marku & m80. All the bits to change the atf cooler & fluid have arrived now so no excuses. Wish me luck!

Did you identify the source of the leak?
Good luck.

Hi there. We did this morning thanks. I have updated the original post but here is the result.
"Hi all. Problem solved! The new ATF radiator was fitted today & took about 2 hours to do partly because of problems removing the bolts & then re attaching them to the rad. The rad bolts are aluminium & the hose bolt is steel. The aluminium ones became stripped & were a devil to get off. The steel bolts then struggled to get an initial grip on the new rad but the mechanic prevailed in the end. 2 litres of atf was then added in stages & a test drive.................. All problems resolved with no judder at all at any speed even with CC on(1st hill encountered it just changed down whereas before this is where it shuddered & felt as though it was trying to change gear). Kickdown works fine, very smooth gearchanges now. So I think the cooler has been leaking for a while but initially with no visible signs on the ground, as it got worse I then noticed the drips on the ground(it wasn't pouring out). I'm not sure how much leaked out when the rad was removed but maybe 1/2-1 litre so the box was at least 1 litre short. The atf fluid did look as though it had been changed recently(the previous owner had said he'd done it last year) so we have left the change for now. On the way out from cold I did 37.1mpg on the computer & on the back admittedly from warm 48.6. I am wondering if I have been driving it in limp mode given such a dramatic change. I drive so slowly I might not have noticed! Thanks for all the help particularly with regards to the bumper removal- they were a great help". As you can imagine I am very happy!" The information re the bumper removal that you & marku gave was very helpful for the mechanic. I would not have been able to do it myself. Thanks again much appreciated.
