1999 2.5TD auto difficult hot start
« on: 17 June 2010, 21:45:30 »
Hi All,

I have problems getting the car started when hot. On a cold start I now glow twice which gives a perfect start without any smoke. On a single glow I sometimes need to crank for about 5 seconds. I believe new glow plugs are required. However, as I understand it, the 2,5 BMW engine doesn't glow when hot, so I don't really understand the hot start problem.( I haven't had time yet to clean/inspect lift pump).

I don't buy into:" the injection pump needs to be replaced ", which one often gets when going to a garage, the car only starts difficult when hot, it runs normally on m-way, enough power on accelaration at traffic lights, etc. Only in kick down do I get smoke.

opinions please

easy test!! when its hot and you want to stsrt it, pour cold water over the injection pump and try to start, if it starts well, then your fuel temp sensor is goosed!! easy to change!! :y
