Hi guys!
Just so you know, There are 2 types of Autotech out there...
1st Generation Autotech internals do not have serial codes nor Autotech logo but they are the ones known to seize. (Happened to my Leon last year...and recently discovered that my cam lobe is more or less knackered...)
Currently using the 2nd Gen internals, difference being that they have the logo & serial number but they said the 2nd gen internals have better protective coating and less likely to break unlike the older designs.
Surprisingly my 1st gen internals ran without fault for almost 40k+ and so far my 2nd gen internals are currently on 20k+ (roughly...touchwood!)
Once I get enough cash together, may just swap for APR. (Not sure when though!)
