The scam, which seems to be making a comeback, sees con-artists secretly pour oil into the coolant reservoir of the vehicle for sale, and then offer a cut-price because they falsely claim the engine is wrecked.
The latest warning comes after a Kent motorist was targeted by scammers, who offered just £1,100 for a £3,600 Volkswagen Touareg after tampering with its engine before a test drive.
OUR BIGGEST EVER BLACK FRIDAY SALE
Michael Browne, from Whitstable, Kent, was selling his 13-year-old vehicle online when an interested buyer contacted him, initially asking for £300 off the car’s price.
An hour later, the buyer showed up to Mr. Browne’s house with a friend and an 11-year-old boy and began inspecting the vehicle before taking the Touareg out for a test drive.
During the drive smoke started billowing out from the car, leading the prospective buyer to ask to check the engine again, which is when he asked for a considerable discount on the price.

The con-artists claimed the car would need a new engine, but when Mr. Browne spotted oil on the driveway he became suspicious and asked the buyers to leave.
Mr Browne said that he had been distracted while showing the potential buyers around the car, which gave the swindlers enough time to pour oil into the coolant reservoir and exhaust pipe.
"While one was looking at the engine, the other one wanted to look at the spare tyre so they got me around to the boot," he said.
"That must have been when the young lad who was around the front put dirty oil in the coolant. I think they used a squeezy bottle. While I was looking at the engine, he must have put some in the exhaust pipe."
After taking the car to the local garage to get its system flushed out, Mr. Browne checked online and realised that the scam is fairly common before taking to social media to warn other private sellers.
