coolant temperature sensor
 
Hello all,

First post for me but a long time observer of this knowledgeable forum.

Recently changed over the CTS in my '89 260e in the hope that my warm/hot start issues would be alleviated but it seems, to no avail.

Between 50C and 90C it's pot luck as to whether it will start or not.

However, if I pull the terminals on the CTS in this temperature range it will start.

Your thoughts would be appreciated..

By disconnecting that sensor the fuel system goes FULL rich. Your engine MUST be starving for fuel when warm.

Most likely a fuel pressure bleed-off problem. try searching for topics with that as a problem.
