Interesting evening. Three blokes came to look at my Passat.
After a short test drive they asked to look under the bonnet.
While I was distracted one poured some engine oil into the coolant header tank and pulled one of the injection connections off.
It ran on three and he dipped his finger into the coolant and tried to claim the head gasket was blown.
I spotted the scam and was telling them to leave and trying to a picture of their car when my neighbour turned up and they jumped in and drive off at speed with the lights off.
Seems it’s a common scam from certain gangs right now.
