Hi 2 all just need some advice tbh. In the process of buying a polo 6n 16v but has a problem with it popping out of reverse on an intermittent basis and therefore not sure whats best way to fix this once iv bought car. Can any one guide me on best route to take as the car it self is very good but this issue. 

Does anyone know why this happens?????

The best that I can offer are a couple of 'might be'

It could be due to worn engine/gearbox mountings.

It could also be the selector linkage that needs adjusting.

It could even be that the gear itself is worn, necessitating stripping the gearbox - unless you are prepared to 'live with it' until it gets worse.

 

Regards

Any honest genuine answers to this problem??

With these cars the best thing you can do is get a gearbox specially repaired. Christian has a great write up about it on his site.

Makes a very interesting read. Baring in mind any gearbox replacement is going to be worth more than the car so you've got to think to yourself, is this a car I'm going to keep....

Could be wrong but I very nearly purchased a caravelle recently with the same problem.  I spoke with my VW specialist and he advised that someone at some point has been a little to harsh with reverse and been shoving it in and it's chipped a tooth.  Am I right in thinking there is no synchromesh on reverse? 

 

To to remedy it you had to hold it in gear whilst reversing which most do anyway so I wouldn't worry to much....
