After the heavy floods Kerala has seen in recent years, many vehicles were written off and their parts ended up in the used market. Most salvage vendors are honest about where a part came from, but it is worth knowing the signs yourself. Water damage is hard to see and expensive to discover later.
Why water damage matters
Water gets into electrical connectors and control units, and the damage often shows up weeks or months after fitting rather than straight away. Corrosion inside a part can make it fail without warning. That is why flood-damaged electronics are the biggest risk, much more than body panels or suspension.
Check for a waterline and silt
Look for a faint line of dried silt or discolouration, and for fine mud in crevices, behind panels and inside connectors. Fresh paint or cleaning in odd places, such as a very clean underside on an otherwise old part, can be an attempt to hide it.
Smell and corrosion
A musty or damp smell on interior parts, seats and carpets is a strong sign. On electrical parts, check the metal pins in connectors: green or white powdery corrosion, or rust on parts that should not rust, points to water exposure.
Be most careful with these parts
Engine control units, airbag modules, instrument clusters, wiring harnesses, power window motors and infotainment units are the highest risk. For any of these, ask the vendor directly whether the donor vehicle was flooded, and prefer a part you can test or return.
Ask directly, and get it in writing
A reputable vendor will tell you the origin of the part when asked. Ask whether the donor car was in an accident, a flood or simply retired, and keep the answer in your WhatsApp chat. On Xspare, vendors quote with a condition grade, and you can ask the origin question before you accept a quote.
