My good old 211k 1995 2.5tdi still goes like train BUT now it is cold and damp in the mornings there is a real lack of power for the first 5 miles then it cuts back in as normal. Probably related to the engine warming up. This started winter last year but disappeared all through the summer. Has just started to happen again in the last few weeks. Once the power is back it is fine for the rest of the day (after subsequent starts).
Anybody know what is going on?

I know nothing about the TD - is the CTS reading ok? Is the engine getting up to temp as normal?

[irpearce]

Yes, engine warms up steadily over first 5 or so miles reaching 90 which is it's normal operating temperature. Rarely goes above 90 except on really long steep hills or really hot days - and then only a bit.

about 50% of tractors are paperclippable.  Worth checking, as being a BMW unit, the EML won't come on for most sensor faults.

first off it should be up to temp after a couple of miles unless your in traffic?
