VW/Skoda Tdi ECU's - Spanner
I read on the site that VW and Skoda Octavia Tdi's can suffer faulty ECU's.
I am thinking of buying a 2000 W reg Skoda Octavia 110 TDi with full history and 100,000 miles but am slightly put off by A) A possible ECU fault that afflicts the VW Tdi 110 engine and
B) It's had 4 previous owners and despite the great condition, I am wondering if it's been through many hands due to problems.

I understand that VW supply an upgrade at some cost but can the original ECU be repaired 'at home' like some ECU's that have been mentioned on this site. Is the fault caused by failure of a component such as a chip or is it nothing more than a 'dry solder joint'
I have successfully repaired dry joints on other ECU's but I am not sure if this known fault on the tdi is unrepairable

Thanks
