Are the black ecu 100501 and 100500 interchangeable?. I am still getting abs tc lights very intermittently at times usually when pressing brake pedal, but recently it did it on startup with only accelerator pressed.

Thanks Richard

Just reading through my old posts and realised I had this answered before, so I will change it and hope for some improvement.

Thanks Richard

All switches working fine then nothing at all, although a few weeks before this happened the passenger front did have a hissy fit and went up and down erratically when closing it.
I removed switch panel to try the checks Gilbert’s described, 47 ohms one side with 900 ohms the other, all of them the same. Does that mean I have a small short? but why on all of them?. I have checked continuity between the voltage reg and board socket but no circuit through D1,presumably that's a diode, would a continuity test work?. Will put board back in morning and check for 12v at regulator, cant see any corrosion and no liquid has been spilt on it.
Thanks Richard.

A couple of weeks ago I was reversing out of a parking spot and put osf wheel up a kerb onto a piece of grass. About half a mile later abs and tc lights came on the off over about an hours time, when switching off the warning traction failure showed up on the dash. Nanocom shows no faults, can’t feel any play in any wheel bearings not sure what to try next.

Further to my post in June, I found oil leaks at the swaged connections on both the engine oil cooler and gearbox cooler pipes, and decided to change the coolers and pipes along with the power steering pipes that were rusty. I also purchased a direnza alloy radiator and also a water pump and thermostat, I bought a new thermostat because the vehicle ran very cool according to the gauge and I presumed that the thermostat was stuck open, it was not. The new water pump has a plastic impeller like the old one but the old impeller has 10 blades whereas the new only has 7 and one side of them are open. In the past I’ve fitted a metal impeller water pump to a previous p38 but could not get one this time. I am thinking of fitting the old water pump back as I am not sure about the open sides on new impeller blades, is the pump with 10 blades an uprated one? If such a thing exists any thoughts?.

Hello, I’ve just bought a 2.5 dse and have been searching the web for information and came across this site, I am looking for information regarding auto gearbox and cooling upgrades for a p38 that has been chipped.
