Can anyone recommend: Mechanic

That's an easy part to replace and you can do it yourself. You should be able to get a replacement at one of these: www.autodoc.es, www.oscaro.es, www.auto-ricambi.eu

However, you will almost certainly have more ratty problems. Your first visitor will have left a urine trail, indicating to its partners in crime that your engine bay is a safe haven. Others will follow. As the weather cools, they are looking for suitable areas to build nests. For some reason, vehicle engine bays are up there with the best. You need to do a thorough inspection of your engine bay as it is very likely there is more damage than what you have already found. Look carefully for bits of straw, plastic, paper, etc. which indicates they've already started to build a nest. Empty Almond shells are also a good indicator. There are two main reasons that they target vehicles. The first is that if you've been out, upon your return, you leave a lovely warm car for them to shelter in. The second, and most worrying is that since around 2008, automakers in their desire to appear more environmentally friendly, have switched from the usual plastic coated wiring to wiring where the coating is Soy based. To a rat, this is food.

 I have researched this problem a lot as I have had horrendous rat problems this last two weeks. So far I have killed seven of them. I use live catch traps baited with Almonds. Do not feel sorry for them, they will destroy your engine.

So, what can you do? First, remove any sign of rat activity. Next, spray the entire engine bay with 20 drops of Peppermint oil in 1/2 litre of water. Apparently. rats hate the smell of Peppermint. I don't yet know how effective this will be as I only started using it yesterday. Be careful not to soak and electrical connectors. Check your engine bay daily. Wipe down all the smooth surfaces with a damp cloth. If you get any more activity, you will see their paw prints on the clean surfaces. Edit: Just been out to my truck and for the first time in two weeks, there is not sign of any visitors. I just hope it lasts.

Good luck.

Thank you. The problem is we waiting for Peugeot to get the part and bank holiday delayed this.  As soon as it husband will put on. We were told you can get an actual spray that you can spray the engine to stop rats.  The reason we wanted a mobile mechanic to see if they could get the part quicker instead of waiting for Peugeot 

Just take it off and tape it up. It will be OK for now. It is the air intake hose for the turbocharger. You can get it here: https://www.repuestoscoches24.es/oen-0382pj
