- I had a Mercedes with an active bonnet fault, I had to look into what the active bonnet system was, then I went back to the car to carry out a diagnosis, the fault code and live data on the scan too was enough to know that the fault was not with the active bonnet actuators, the fault was with the pedestrian sensors that at on the front bumper.
I found a broken in two sensor on the left hand side.
I am sharing this video without the fix because I was only diagnosing the car.
It still way help someone with an active bonnet fault.
Thanks for watching.
Cheers Matt good information, one to watch out for many thanks Sandy
I had never seen this hinge assembly before,
Thanks for watching
First I Have heard of it Matt. Thx
When I first looked at it I stopped to do some research on what it was and how it works before going back to it.
It saves time in the end.
Thought I'd share what I found Incase it help someone. Thanks for watching
Great stuff mate i haven't come across this system but its good to know 👍👍👍
It was new to me too, it's the same customer that had the BMW with the electrical coolant pump which was new to me too, he must think that I don't know about cars when I say I haven't seen that before 🤣
Very good Video, May icarsoft dignostic is not able to resolvd the d18e and d18d Error. Changing both Sensors eliminated only the d18d,but Not the other . In your Video you have the d18c Code . Maybe i will also Change the yellow Sensor
well done matt
It's a strange one, at first when the customer told me about a bonnet message I thought it would just be the micro switch in the bonnet latch, I'd never heard of an active bonnet.
Thanks for watching
thank matt for video
Hmmm never heard of that type are hinge action before....pretty cool indeed..well at least for the pedestrian 🤣
I wonder if anyone has been hit by a Mercedes and thought " thank God for the active hood system" lol. thanks for watching
@@mechanicmatt871 LOL... I bet...nobody.... but you never know... :)
Hi
Have you heard of vcds Ross tech and all analog copies for it .so you have the cable with obd2 adapter on the end .plug to your computer and work with it
Do you know any alternatives for multi car scanning and changing parameters what vcds can do ?
Thank you for your upload .
We always hungry to get any help from video like yours.
Cheers
I have used the vcds Ross tech at a garage I once worked at, and if up using other scan tools, some are better on some cars than others. If it is pc based that you want have you looked at Autoenginuity. It may be what you are looking for.
Thanks for watching.
How much was the replacement sensor if you don't mind me asking? I've got the same issue and although I've not seen the sensor itself I believe that's what it is. Similar situation and my bonnet also never popped.
I have seen used sensors on eBay for around £50, the customer bought his own sensor for me to go round and fit. I'll ask him what he paid when I see him. Thanks for watching
@@mechanicmatt871 Thanks for that mate. Been looking for something on this for ages and this is the closest I've seen to a solution. Got yourself a new subscriber.
Alistair McNaul did you find it? I also got on my cla - active bonnet malfunction. I was wondering if it’s easy fix?
Did you fix the message with active bonnet malfunction?
Yes I managed to put the damaged green pedestrian sensor in the bumper back together and the message on the dash was out without even clearing the fault code.
Thanks for watching
Do you have any picture of the sensor?
My s class is give me active bonnet malfunction
The sensor wich you put is that one with the pipe between the 2 sensors?
Looks like this, except it was green, you can just see it near the end of the video
