2021 Citroën C5 Aircross SUV RELIABILITY Review | Citroën C5 Aircross Possible Issues | CarMaster 

Badhiya... Ekdam clear hogya sab. 💯

Citroën quickly realized that standard brake fluid was not ideally suited to high pressure hydraulics, and developed a special red-coloured hydraulic fluid named LHS (Liquide Hydraulique Synthétique), which they used from 1954 to 1967. The chief problem with LHS was that it absorbed moisture and dust from the air, which caused corrosion in the system. Most hydraulic brake systems are sealed from the outside air by a rubber diaphragm in the reservoir filler cap, but the Citroën system had to be vented to allow the fluid level in the reservoir to rise and fall, thus it was not hermetically sealed. Consequently, each time the suspension would rise, the fluid level in the reservoir dropped, drawing in fresh moisture-laden air. The large surface of the fluid in the reservoir readily absorbed moisture. Since the system recirculates fluid continually through the reservoir, all the fluid was repeatedly exposed to the air and its moisture content. LHM reservoir and green suspension sphere in a Citroën Xantia To overcome these shortcomings of LHS, Citroën developed a new green fluid, LHM (Liquide Hydraulique Minéral). LHM is a mineral oil, quite close to automatic transmission fluid. Mineral oil is hydrophobic, unlike standard brake fluid; therefore, water-vapour bubbles do not form in the system, as would be the case with standard brake fluid, creating a "spongy" brake feel. Use of mineral oil has thus spread beyond Citroën, Rolls-Royce, Peugeot, and Mercedes-Benz, to include Jaguar, Audi, and BMW.[21] LHM, being a mineral oil, absorbs only an infinitesimal proportion of moisture, plus it contains corrosion inhibitors. The dust inhalation problem continued, so a filter assembly was fitted into the hydraulic reservoir. Cleaning the filters and changing the fluid at the recommended intervals removes most dust and wear particles from the system, ensuring the longevity of the system. Failure to keep the oil clean is the main cause of problems. It is also imperative to always use the correct fluid for the system; the two types of fluids and their associated system components are not interchangeable. If the wrong type of fluid is used, the system must be drained and rinsed with Hydraflush (Total's Hydraurincage), before draining again and filling with the correct fluid. These procedures are clearly described in DIY manuals obtainable from automotive retailers. The latest Citroën cars with Hydractive 3 suspension have a new orange coloured LDS hydraulic fluid. This lasts longer and requires less frequent attention. It conforms to DIN 51524-3 for HVLP.[22]

Great 👍

I'd rather wait and see the after sales experience first, from #citroen . Although as a product, #c5aircross seems to be an excellent#suv

The ease with which you cleared my doubt regarding this progressive hydraulic suspension.... Subscribed 👍

Fantastic content bro..

I'm really awestruck by the interior of the C5 AIRCROSS. Money no bar, I'd happily go with Citroen over any other Suv under 30 Lakh Rupees.

Would really like to see how it fares against the VW Tiguan and Skoda Karoq . Seems to be an interesting car. #Great #Content as always.

Kammal hai bhai ...agar road acche ho tho itna advanced suspension ka kya zaroorat? Bure road ke liye tho ise kharredni hai

Is it value for money to buy the new Jeep compass costing around 32-33 lakhs on road for the s variant diesel automatic please make a detailed video on it to buy which variant of the new Jeep compass in diesel automatic

Sir, which car is best according to comfort (sedan vs SUV)

What would be your pick in choosing a midsize SUV in automatic with good space , comfort , safety , driving pleasure and a good looking one
