Hi All

I've had my 2011 Jaguar XF 3.0D S since March and, like many who researched their purchase in advance I'm sure, I was aware of the danger of triggering the bonnet airbags but never thought it would happen to me.

Starting out on a 3 hour drive from the south-west to Hemel this morning at 4am, I stupidly decided to nip though the very twisty single track lane to save myself 5 minutes. First tight bend and there's a fox in the middle of the road. It dived for the hedge, I swerved in the opposite direction as far as I could, and literally clipped it gently at about 10-15 mph.

BANG

Bonnet blows, hazards on, very loud profane exclamation. Look in the rear view mirror, fox trotting off like nothing happened.

No damage to bumper, no mark at all.... are these stupid things meant to be this sensitive????

Sadly, yes. What seems like a light impact to a pedestrian's legs is more than sufficient to flip them onto the bonnet of a car.

How's the car meant to know you hit a fox, not a child?

If you want to blame anybody, blame the stylist who drew a bonnet line low enough that there's no room for the bonnet skin to deform and absorb energy before that small pedestrian head-butts the chunky and unyielding mechanicals beneath...

Or the fox. You could blame the fox.

Didn't set out to apportion blame, but of the two - I'm going with the fox

Tony Blair is the reason the fox was there in the first instance.

Is he also to blame for the system being set up so as to destroy the bonnet hinges rather than having the scope to deal with this eventuality? If so, he got sworn at very loudly in the early hours if this morning

Well, if the stylist had allowed more space, the pyrotechnics wouldn't have been needed to get even such a fairly ho-hum pedestrian score.

The results are noticeably better, especially in the area of the bonnet likely to be struck by a child's head.

All good stuff... and thanks for looking it up thumbup

I still do believe it's somewhat oversensitive, but I suppose better too much than too little when it comes to pedestrian safety.

Interestingly the Main Dealer estimate (without sering the car) has just come in.... wait for it.....

c.£2000 - more like double if the bonnet is doomed!

Crazy

As a comparison.. trusted specialist Indy using tested used parts... change out of £500 (if the bonnet's ok)

By now, I'd have thought used ones would be available, unless they're coded to the body computer, or similar silliness.

I recall the horror story about the Nissan R35 GTR that had a low speed shunt in traffic causing minor damage to the bumper but had a £20k repair bill thanks to various rams , electronics and hinges that needed replacing . You can actually buy the kit to switch them off on R35's and 370z due to people worrying about this , but for me thats why we have insurance

So in and out of the garage today.. local specialist Indy is fantastic!

£186 for a used pair of bonnet airbags and bonnet hinges from Eurojag, couple of hours labour...

Just over £300 all in. Phew!

Not so bad at all. Lucky the bonnet wasn't damaged.

While it's not something I'd wish to disable... would be good to dial down the sensitivity a touch.

Where I live it's pretty common to hit rabbits/badgers/foxes etc. And even with no body damage, three or four hundred pounds a time (depending on parts availability) is a bit of a ball-ache

Yes, yes - of course I'd rather that than kill a child etc., but there are plenty of stories of random activations. Shame there's no fix availabke

When my 2011 XF 3.0D struck a couple of hard objects the bonnet went up and back, and kinked a bit, but I didn't see any airbags (other than the ones in the cabin).
