Curl in PHP like a Real Browser Still Detected as a Bot - php

Question

So I'm trying to just get the HTML from a page. I have added any possible data into curl headers SSL anything. But they still know that its a CURL BOT. How can I bypass this or how they do it?
When I visit other pages from them I dont get Detected as a Bot only when I'm on search
$url = "https://suchen.mobile.de/fahrzeuge/search.html?damageUnrepaired=NO_DAMAGE_UNREPAIRED&isSearchRequest=true&maxPowerAsArray=PS&minPowerAsArray=PS&scopeId=C";
$data = curl($url);
echo $data;
function curl($url, $post = "") {
$cookie = "cookie.txt";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_ENCODING, '');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36');
curl_setopt($ch, CURLOPT_HTTPHEADER, array('authority: suchen.mobile.de', 'path: /fahrzeuge/search.html?damageUnrepaired=NO_DAMAGE_UNREPAIRED&isSearchRequest=true&maxPowerAsArray=PS&minPowerAsArray=PS&scopeId=C', 'scheme: https', 'accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8', 'accept-encoding: gzip, deflate, br', 'accept-language: en-US,en;q=0.9', 'upgrade-insecure-requests: 1'));
$data = curl_exec ($ch);
if (curl_error($ch))
return "Bad";
if (curl_getinfo($ch)["http_code"] == 200)
return $data;
