Driving my wife's Passat last night there was a very loud bang from underneath the drivers seat after stooping and investigating I found a large spring with a number of pieces of broken plastic. The seat still works OK back & forward and up & down. I have had a look under the seat but can find nothing. I am a bit reluctant to remove the seat owing to the side airbags. Has any one come across this before and can offer any help.On another prob with the car she has had the usual probs with the front suspension after changing one or two parts for the problem to occur again I took the bull by the horns and ordered from Germany a complete new set of suspension parts at a cost of £140.00 delivered in 36hrs and my local garage fitted them for £100 and no probs for the last 10k. I must be a bit mad as I am getting my wife a newer Passat the latest model but a Tdi, I have had Passat's for over 25 years in fact my current car is a GL5 Estate 85 which I have had since new and still going strong
