Hi ya

I've got a 1.9TDi X Reg Alhambra.

I've got a problem with engine judder when the engine is warming up from cold.

From cold the engine is fine and I don’t get any problems, from about 10 mins into my journey the engine judder's quite erratically when accelerating and at idle. Once the engine has warmed up fully (90 degrees) I turn the engine off, then re-start and it runs perfectly fine after that.

Its been plugged in to check for faults which showed the following which have been replaced but the problem still occurs

MAF Sensor
Fuel Temp Sensor
Coolant Temp Sensor

Last week my collant was empty and I topped it back up and I had to do the same again this morning (never had to top it up in the 5 years I've owned the car). I'm not sure if this is related to the above problem or not.

My garage are now scratching their heads at this one and said the next thing to do is to get it checked at Seat (which I'd rather avoid). Can anyone help me please!!!
