Hello all I am in need of some advice. I have a 03 L322 TD6 and for the last week I've noticed when I'm driving around 50mph the car slightly judders. If I take my foot off the gas and let it slow down on it's own it gets worse and when i start to brake it almost goes. I've had the front brakes done and it feels like it's coming from the front not the back. also when I get out the car it smells very hot.
Any advice please, thanks
 
I'm guessing it's an auto? have you had your gearbox changed yet? What mileage are you on? The l322 gear box is made from cheese and usually breaks around 100,000 miles...
 
Yes it's an auto, it has 120,000 on it and don't think it's been changed but it runs up and down the gears fine
 
Ok I'll get that looked at, I was hoping it wasn't the gearbox as it runs through the gears just fine
 
New disks can warp if there not bedded in right, just worth a look, and do the gearbox oil anyway look for bits and colour of oil.
 
Smell and symptoms sounds like sticky caliper and warped disc to me. If you've had the brakes done, i.e. new discs and pads, but no work done on the calipers, it's not unusual for them to go sticky. The thickness of the new pads moves the caliper along the sliding pin to a position that hasn't seen any use for a while. If it's rusted, dry or pitted, the caliper will stick. FWIW, if the brake job was done very recently, you still haven't worn off the bedding-in coating on the pads, which inevitably leads to hot brakes and smell. This is why you should use your brakes intermittently and decisively during the bedding in period, to allow them to cool off as much as possible between workouts.

I guess the clues are, 1. it slows down on its own and 2. the juddering stops when you brake and 3. the smell. Take it for a drive, stop and see which wheel smells and it will probably be warm to the touch. If you did the brakes yourself then check them soon, if you didn't then take it back

Really, try going down the Horseshoe Pass in North Wales and tell me if you are going slower at the bottom than when you started at the top. As Wammers posted you have missed the point, there is a difference between normal speed retardation when you lift off the accelerator and when you have a brake not fully releasing.;):)
 
A sticky caliper can be easily diagnosed.. After driving it, put your nose into easy wheel well. you'll smell the difference. wave your hand slowly at the face of each wheel. you'll feel when one is hotter than the others. in some cases, the brake disk will start to get a bluish tinge. Dont leave it for long at all. it cooks out the lubricant in the bearings and you'll end up needing a new wheel bearing as well as a brake disk and pads again

+1 to all of that! And sometimes smoke from the wheel if binding badly.
