Could you post the ad and any additional info that you’re aware of?
Mac’s advice should be taken as the blueprint for the ideal route for FSi purchase, however if a pre-purchase scan isn’t practical or the seller doesn’t want to facilitate, the car is otherwise good and cheap enough - and you’re good with the spanners AND happy to take a risk, then we may be able to help further guide your thinking on this particular car. However, the fact that the fault has been present as long as it has - plus your indication that the seller didn’t describe it in the ad - would suggest you should be cautious!
This was my sisters car, who sadly died, I inherited it and decided to rectify any issues and flip it, Ihave another one to flip too!
One didn't mention the previous EML because one didn't know it had been there, (but only as an advisory it seems,) until I set to work on it! Suspicious huh?
I'M NOT IN THE BUSINESS OF LYING TOPEOPLE.
I know these cars, I still own a 1.4Petrol which I also rescued: It's had clutch, aircon compressor, 4Xcccu! starter motor, door locks repaired, front wheel bearings,struts top mounts and bearings, rear springs, refurbed alloys etc etcSo you get the picture?
The 1.6 is a great car, I may even keepit as it's low mileage, and sell the 1.4.
I have repaired the broken vacuum valve actuator arm which works fine and the flaps operate, but the fault still remained, even after adaptation, I have since diagnosed the fault was returning due to a faulty position sensor, (potentiometer.) Which will be replaced when it arrives on Tuesday or Wednesday.
This is the VCDS reading before clearing the fault.
17439 - Intake Manifold Tuning Valve(N136): Setpoint Not Reached
P1031 - 35-00 - -
“Setpoint not reached”, in otherwords, the potentiometer is faulty, (the voltage reading didn't changewhen running basic settings.)

If you can wield a spanner there'snothing you can't fix yourself on these cars.
They're an appreciating classic andwill only go up in value
The car drives perfectly and fliesalong with or without the “fault”
Perhaps the OP should just buy a newcar?
