Hello,

I have this W140 S500 WDB1400512A197157 engine cut off when hot. So far what I replaced were:

1, Crankshaft sensor
2, Camshaft sensor
3, Fuel pump x2
4, Fuel filter
5,Temp sensor (single connection)
6, Distributor cap x2
7, Distributor rotor x2
8, Electronic throttle valve ( MOST EXPENSIVE )
9, Fuel pump relay
10, HT cables x 10 (including 2 coil cable)
11, Spark plugs x8

What I have NOT replace
1, Coils x 2
2, Ignition control unit
3, ECU
4, MAF sensor

Any solution or did i miss check something ? Any advice ?

Thanks.

I believe coils often fail with heat.

I'll give it a try and see if there is firing when it cut off.

Thanks.
