Can anyone offer advice on the problem I have with my W124 M104 6 cylinder engine?
From cold, the engine starts first time without problems but just for 2 or 3 seconds or so before the engine shakes as if it is not running on all cylinders.
If I keep my foot on the accelerator (1,000 to 1,500 revs) the shaking continues for about 2 minutes then stops and she runs smoothly.
After this happens (on two separate days), I drive the car for about 30 miles with town and motorway driving and she responds perfectly.
The car is kept in a dry garage but as she is run only on dry days, sometimes the interval between runs may be several weeks.
The battery is fine as it is linked to a battery conditioner. The engine has covered 87,000 miles and has been serviced regularly throughout its life.
The vehicle is going in for an "A" service on 2nd December.
