Hello I went looking at a 2007 Octavia 2.0tfsi today with 106000 miles on the clock , all felt well when driving and the car interior is clean and the bodywork is immaculate especially for the age couldn't find any scratches or dents even that many stonechips really wheels have very little to no kerbing . 

Before taking it for a test drive I notice the coolant light flashing on the dash and the brake pad warning light on . look at the coolant and it was below minimum so topped it up with water , my first thought is obviously the dreaded head gasket , oil pump , water pump maybe ?? There isn't a drop of oil in the coolant tho. But the coolant warning didn't go off even tho after a 15min spin it didn't drop again . 

I know the brake pad light can come on even if it looks like there's plenty of life on the pads. 

One big put off there's only service history to 20,000 miles . so I don't know if the timing belt has been done . 

The dealers story is that the previous owner was a technician at a garage so he must of done work himself , only thing I've got to go off is how clean it is especially the bodywork no dents or scratches and when the engine is running can't even ear it in the car . 

Have these engines got a cover at top of the timing belt which clips off so I could see the condition?

No service records whatsoever?! I would walk away. 

Hi, you right to question the integrity of this car and without being slanderous the dealer, of course as the is no smoke without fire, 

anyway if the car is what the dealer says it is he souls have no objection to giving you the previous owners details, after all if reassures you enough to purchase the car, for him it's a win win situation 

in short you have nothing to lose by asking

a negative reaction would mean you ought to walk away, quickly
