While I await the shop manual let me run one past the 240D gurus here.

I was told when I bought her that the vac pump was gone, today I hooked up a gauge/pump to test, I sampled in the main line to the brake booster, after about 30 sec I get 20" reading, when I dump and resample while running, back to 20" in a second, is 20" high/low/normal ?

2nd, when I turn her off, takes about 3-4sec to drop to 0", I'm thinking mabey a bad booster ?, thoughts ?.

Starts when using block heater in about 5sec, wont start with out, checked glow plugs, 11.3 volts on 3, 2 volts on one, have new ones on order, will 1 bad plug stop these from starting cold ?, batt reads 13v in the morning before starting, 13.8v running, seems to be cranking fast enough but then I am new to the Benz oil burners, thanks in advance for any/all input.

Don
