Am scris o aplicație care citește mașina prin mufa OBD2, după ce Volkswagen a închis We Connect

Mă numesc Davide, sunt din Italia și lucrez singur la aplicația asta.

Am început-o pentru mine. Volkswagen a oprit We Connect și am rămas fără nimic care să îmi arate drumurile și consumul real. Mașina are datele înăuntru, în calculatorul de bord, și cu un adaptor OBD2 ieftin, unul ELM327 pe Bluetooth, telefonul le poate citi.

Partea tehnică, pentru cine se uită la ea. Totul rulează pe telefon. Nu există cont, nu există server, nimic nu pleacă din aplicație. Se plătește o singură dată, fără abonament.

Ce m-a costat cel mai mult timp nu a fost citirea datelor, ci faptul că fiecare mașină răspunde altfel la aceleași întrebări standard. Uneori răspunde altceva, alteori nu răspunde deloc, și atunci nu ai ce inventa.

Un exemplu concret. Pe grupul Volkswagen se citesc gramele de funingine din filtrul de particule. Pe alte mărci se vede doar când pornește regenerarea, și numai dacă mașina dă temperatura. Pe unele nu se vede nimic. Nu promit mai mult decât scoate mașina.

Este pe Android și pe iPhone. Adaptoarele proprietare, cele care vorbesc doar cu aplicația mărcii lor, nu merg.

Există o probă gratuită de 7 zile sau 15 drumuri, aplicația întreagă, fără card.

今これに乗っているのだけど・・

Hydractiveを搭載した最後のCitroen C5 exclusive。

2台目の車をBMW miniにしたらこれが快適でCitroen C5に乗る時間が極端に減ったよ。

年間走行距離ではBMW miniが20,000kmに対してCitroen C5はわずか1,000km。

なんか「置物」になっていて維持費だけがかかっている感じ。

歴史的な「最後のHydractive」をこのまま維持していくか故障しないうちに売ってしまうかちょっと悩んでいるよ。

Citroen / Stellantis VIN spec decoder

Many brands offer useful VIN recorders (like the Mini), which provides comprehensive vehicle spec information. I’m looking for a reliable VIN spec/trim decoder for Citroen that goes beyond just the year and engine version. I’m trying but struggling to decode C4 2017

Does anyone know any good vin decoder?

Citroën C5 2010 Diesel – Won’t Start After Driving, Even After Replacing Battery and Alternator. Please Help!

Hi everyone,
I own a 2010 Citroën C5 diesel, and I’ve been having a very frustrating starting problem. I’m hoping someone here has experienced something similar or knows what could be causing it.
Here are the symptoms:
● Sometimes the car starts perfectly fine, but other times it won’t start at all.
● When I try to start the car, I only hear a clicking sound, and the engine doesn’t crank.
● If I connect jumper cables to another battery or vehicle, the car usually starts again.
● After driving for a long distance, if I turn off the engine, the car sometimes refuses to start again.
● I’ve also noticed that the problem seems to happen more often when I park the car facing downhill.
● On some occasions, the engine has started but then stopped shortly afterward.
What I’ve already replaced:
● Brand-new battery.
● Brand-new alternator.
Unfortunately, replacing both parts hasn’t fixed the problem.
The strange thing is that the car can drive normally, but once I switch off the engine, it might not start again without a jump-start.
I’m wondering if the problem could be related to the starter motor, a bad ground connection, battery cables, an electrical fault, or something else.
My questions:

  1. Has anyone experienced this problem with a Citroën C5?
  2. Could a faulty starter motor cause these symptoms, even though jump-starting helps?
  3. Could it be a bad ground cable or another electrical connection?
  4. Why would the problem happen more often when the car is parked downhill?
  5. What should I check before spending more money replacing parts?
    I would really appreciate any advice or suggestions. I’ve already spent money replacing the battery and alternator, and I don’t want to keep replacing parts without finding the actual problem.
    Thanks in advance!

The Citroën DS21 Henri Chapron:

Far away in a land of croissants, baguettes way before I graced the earth Citroën unveiled a stunner.

Citroën revealed the Citroën DS on 5 October 1955 at the Paris Motor Show or…or the Salon de l'Automobile de Paris. Said that with an accent by the way, looks like those Duolingo lessons are doing something. The Citroën DS caused somewhat of a sensation to the point where 12,000 people ordered the car. 12,000. By the end of the first day mind you. People looked at it and said hell yeah we want that. Don't blame them honestly I mean just look at the car. Citroën called the car DS, a play on déesse, their word for goddess……. who names a car goddess I will tell you who the French. The companion model was called ID, a play on idée meaning idea. A bit abstract isn't it, goddess, idea what's next.

Henri Chapron, the French coachbuilder in the stands at the show when the DS was revealed. He saw it and decided that he wanted to put his own spin on it. Citroën however would not give him the chassis. So Chapron took the only logical next step. He started buying complete production cars. He converted them and Citroën was impressed. Of course they were it's Chapron. I'm told he was well regarded in the car industry. They contracted him and the factory cabriolets were born. 1,365 were built between 1961 and 1978.

The DS21 Chapron had an enlarged 2.1 litre engine producing about 106 horsepower and the "famous" hydropneumatic suspension that made the car feel somewhat like a magic carpet ride. A magic carpet ride, what is this Aladdin. Anyway it was unlike anything on the roads in 1965 and honestly its unlike anything on the roads today, it was self levelling and height adjustable. I hope that excited someone. The standard DS was already a pretty sight but the Chapron coupe and cabriolet made it prettier. The roofline was lowered and the lines sharpened and the result was something that looked like it belongs in those old black and white French films where 2 people are insanely in love with each other but for some reason want to make everything so philosophical so they never really get together.

The Concorde coupe in midnight blue is a stunner, you will definitely stop and stare and the Le Dandy coupe is basically a wet dream for collectors and only 15 were made which means only one thing. They are going to be fucking expensive. The French make beautiful things clearly problem is though they become insufferable about it but then again doesn't everyone if they make something beautiful.

So the story here is they named a car goddess, refused to help the coachbuilder but the coachbuilder said you will not stop me (in a French accent) and made a better car, and now he has his name embroidered on a car. How wonderful.

Brake switch

Hi, my cruise control is not working so I will be doing diagnostics later. In case its brake switch, I have c4 mk1, 2005 with TU5 engine (1.6 16v 80kw).

What is the difference between these 2, are those for the same model at all (website shows both of those compatible)?

The third image shows my actual brake switch.
