Hazard warning relay

[tinkboats]

I have a 2016 Berlingo Van
Today the hazard lights came on continuously 

I tried finding the fuse but the inside fuses are located behind such a mess of wires I couldn’t access them, this has to be the worst piece of design ever.

I am getting conflicting information on this forum and the web in general

The flasher relay appears to be replaceable but some post say it’s behind the steering column and some that it’s built into the BSI, 

Can some give me a definitive answer, if on BSI does the whole thing need replaced  

Thanks

With any weird type faults on the B9 Berlingo [and a number of other PSA group vehicles of that era] the engine bay fuse-box is one of the first items to check. This is located adjacent to the battery. They are well known for problems, in that they can suffer from water ingress that gets into the box, which is not only a fuse-box but also contains an electronic circuit board on the underside that communicates with the BSI and controls many functions. Ingress of water onto this board can cause the board to short circuit and cause all sorts of weird faults. An example being on my Berlingo the headlamps and wipers would randomly switch on, when the car was parked up and the ignition off! I also used to get random ABS warnings.
To examine this fuse-box for any signs of water damage disconnect the battery [after waiting the appropriate time for the vehicle to go into sleep mode] and look for signs of water in the fuse-box. If nothing evident, pull each fuse out in turn looking for any sign of water damage on the fuse prongs [which will normally show as corrosion on the prongs] Clean the prongs as required and spray with electrical contact cleaner and refit. 

If your box does show signs of water damage, you must find the source of the water. The most common cause being blocked scuttle drains at either end of the engine bay underneath the front scuttle [you have to remove the wipers and three torx screws holding on the cover] to examine whether the drains are blocked. Most commonly these get blocked with leaves and other debris and then water overflows into the engine compartment flooding the engine bay fuse-box.

Unfortunately in my case the electronic board was so badly damaged, I had to replace the whole engine bay fuse-box, which if you have to go down this route make sure you get EXACTLY the same part number as is fitted to your vehicle, as there are a number of different versions [which look very similar but are not compatible] The good news, if you do have to fit a new fuse-box is they are plug-and-play, with no coding necessary. I picked up a second hand unit for about £35 delivered.
