Mercedes cold start problems

Cold start problem on ml270 hello,good day,check all line for diesel leaking, or your fuel flow back to your tank, try to check your fuel filter,renew if necessary,ty May 11, 2009 | Mercedes-Benz ML-Class Cars & Trucks Sprinter Fuel Rail Pressure Regulator Problems – Poor Starting Posted on by The Mercedes CDI series of diesel engines have an electronically controlled fuel pressure regulator mounted on the end of the fuel distribution rail. The problem in this case, however, is more likely to be the cold start valve rather than the warm-up regulator. This is underscored by the fact that the car starts and moves successfully after adding starting fluid, even though the engine has not reached operating temperature. I have a customer with a 2005 E200 kompressor M271 engine with cold start problems. When the engine is completely cold (eg leave the car parked for one night) it does not start with the first cranking attempt. If you crank the engine after the first attempt, it starts without any problem or delay and idle behavior is good. Finally I found the solution for the cold start problem (560SEL 1989). Here is the whole story (read it if you want to have some experiance) Previously I posted asking about the cold start problem. The problem started when I changed the EHA Bosch unit that is mounted on the fuel distributor. Just started having problems starting: the engine turns over a few times before "catching". This morning, first real frost, the engine turned over 10+ times before starting. Called my local Indy and 20 minutes later the Star thingy said it was a faulty glowplug relay. Just found this post so am happy that the problem will soon be resolved
