I had a problem changing gears on my Polo (1997, 1.4 petrol, 3 door, UK). It was hard to find the gears especially 1st and 2nd, and reverse would grind, and it was worse when the car was warmed up after a few miles. It had a new clutch cable (it snapped) and that fixed it for a week, and then a new clutch after that which help a little again.
But there's an intermittent problem with changing gear, it's not reliable and I can't tell if when I get to a junction whether I will be able to get into and out of first gear.
My mechanic says it is a problem with the gear linkage. Originally he thought it was the "connectors on the end of the selector cables" but now he says it's "the linkage between the selector and the linkage to the gearbox" and specifically related to "a 13mm pinch bail" that hold a rod that is part of this.
He says it is easily repairable but that he can't get the parts. I've tried to look myself, but I'm not mechanical at al so haven't been very successful.
Does this make any sort of sense, and if so are there any suggestions as to where to look for parts or instructions to give to a mechanic?
