Hi
I have a 98 mk4 tdi 90hp, non PD. A few days ago I had to drive through a deep puddle (which came up to the lights) as the road was flooded. Since then when idle at lighs/stationary the car is a little lumpy and the car gets quite shakey. It drives fine just when idle. Also when I give it a little rev it seems ok.
I haven't checked anything yet, scared of breaking something!
Thanks
