Subsequently and due to the Council from the workshop I bought this spray.
So made engine wash and sprayed the engine compartment with it.
By the way, this stuff stinks like Katzenpi..e. So when the Mardar there goes ran, he has no more sense of smell.
This was my idea and good cheer, I was able to continue.
But it is well known, always different than you think.
14 days after the first repair and about a week after treatment with the spray ... renewed damage to the radiator hose by marten bites.
After another 100, - Euro repair costs now I have looked around for another solution and it seems to be quiet (on wood knock) at the moment.
CONCLUSION:
There may be the marten find that stuff so repulsive that you stay away from the car. For me, anyway, this investment has not paid off.
A PITY
So much for the statement on the bottle: reliable protection against marten bites. - Well ...
