Electrical problems at the CRV

I’ve been driving this car since 2011, I’ve had 144,000km so far and hardly had any problems. If there were any then they were mostly in debt themselves, but I always got away with a blue eye. It started that I attached day running lights myself, exactly according to regulations, it also worked until suddenly an error message came, some sensor in the engine was defective, please immediately go to the workshop. Had still warranty, so in the Honda workshop. Yes we order and change The part (costs were probably 800€) . After the change I wanted to pick up the car , the locksmith showed it to me , the error message appeared again . The jumped almost to the ceiling . That can’t be ,……I asked politely , can that be because I connected the daytime running light to a fuse in the front fuse cgass ? The jumped out of the car , bonnet open , ripped off the cable and the error was gone ! The rest I don’t tell! Similar happened to me 6 weeks ago , Stoppl Is a bulb defective. Petrol station bought new bulb and screwed in , burned again . Suddenly all alarm bells in the car .an. What there were error messages lit up . Off to the workshop , which plugs computer , stop light switch defective . Well – changes it . Come on , everything i.e. turn on the car – it was the same as before . That does not exist . Computers on closed , searched and searched . I ask the locks this can be related to that I have a bulb defective . I had one built in with a contact at the bottom of the base and had to enter one with two contacts. I didn’t even look at it. Now I was yesterday to change oil. I have to mention here maybe, I have been living in Hungary for 7 years have re-registered the car here. The workshop, I don’t think there is any more in Germany, but is specialized in Honda and makes very good and d cheap work. The car was driven in, doesn’t know who that was, he spoke German and told me you had to change the ?.. magnetic switch(?) ignition lock. When I start the car noises come as if there was a loose electrical connection. I’ve had that for a very long time and it’s not always. He has an old car recycling company and can bring with such a part (70€). Who knows what that is? I write something after that. Must go to the workshop. With a buddy. I am looking forward to an answer!
