recently the car has been havinig trouble getting into access height. It doesn't always happen but sometimes it will vibrate and struggle a little when it goes down. Is this normal?

mine does this sometimes, usually after a cold start, not had an error messages or any suspension air compressor failures as of yet, so presume its all good.

Mine has not displayed this symptom but if there is no error messages then I would not worry about it.

I say to myself, that if I ask the car to raise or lower and it takes it's time, then there is a good reason for it, such as the compresssor is not charged enough, or the car is too busy doing other more important things! L319 D4 HSE
