Re: [MBZ] IP Advance (??)
My '78 240D has a knob on the dash which advances the IP somewhat for cold It just pulls on the throttle linkage a bit. High idle, in other words. Newer cars do the same thing automatically, via idle speed regulation. So far as I know, timing on these cars is _only_ affected by RPM. -- Jim

Re: [MBZ] IP Advance (??)
The '78 and 79' SDs had the fast idle knob. They stopped them on the '80 model year cars.

[MBZ] IP Advance (??)
Andrew S. wrote: it stalls with a cold engine). Howdy - My '78 240D has a knob on the dash which advances the IP somewhat for cold starting (at least that's what I think it's doing) and once the engine is running smoothly, the knob is turned back putting the IP timing at its proper place. How do the newer diesels accomplish this? I assume there's some sort of automatic IP Advance but haven't run across it on the mechanical diagrams (but I haven't really looked). Is that a correct assumption?? Also, if the advance (if that's the proper term for it) is not working on the newer cars without a knob, will that be the cause of poor running while cold? How is it lubricated/serviced?

Re: [MBZ] IP Advance (??)
It just pulls the linkage a bit to give a faster idle -- otherwise they tend to stall when very cold. It does not affect injection timing in any way, unlike the cold start device on the VE rotary pump on the Volvo -- that is responsible for many cases of early engine wear because it DOES advance the injection timing quite a bit, and does so long after the engine is fully driveable.
