Hi

I havent post anything for a few years as ive never had a problem with my car. Over the past five weeks my car octavia 1.6 tdi 104000 miles has been losing power intermittantly. I only get the glow plug light flashing on dash and not the engine light. My code reader indicates fault code p0101 everytime glow plug light comes on. Local garage says its the turbo waste actuater. So i replaced it and problem still persisted so i replaced the MAF sensor as my code reader indicated but problem still persists. Could the egr be at fault? As i know these can be problematic and pricey car is not a town car and gets plenty of motorway miles. Any advice would be appreciated. 

wouldn't be surprised --grossly over engineered (in my opinion)   you really need vag com to scan I think
