We have recently bought a Vauxhall Astra 1.6 SXI, 6 months old, on a 56 plate. We are very pleased with it, except for one annoying problem, which, surprisingly enough, the garage cannot seem to find the solution to. OK, often, when first starting in the mornings, on engaging the clutch and putting it in reverse or forward gear, the car will judder slightly and feel as though its movement is being impeded somehow. This feeling lasts for a couple of seconds max, before it trundles on its way quite happily. This event only occasionally re-occurs when the car is warmed up and in motion, but mostly the problem is noticeable after the car has been stationary and with the engine switched off for a few hours. I don't wish to cloud the issue at all, but the problem does appear to occur more frequently when it has been raining or when there is a lot of dampness in the morning air. This last point may not be relevant, but I thought it best to include everything for your consideration.
Any help will be gratefully appreciated.
