[windy]

Hi just put a new MAF unit on my 2.5 tdiT4 and there is still no power when driving when you rev it up it sounds wonderful but when your on the road it's hard work solved all the other problems oil leak flashing glow plug light ect. Can anyone help?

P.S sorry plumb bob cleared all fault's and glow plug light has never flashed since
