Found on drivers door sill .

Clearly relates to an ECU re-programme but anyone know why it was done and why?

 

Very likely it is a replacement. The early US models had a capacitor leakage problem that could destroy the circuit board and the same problem may occur in the UK.

 

Hi,
See attached TSB 303-35

 

As always bang on the money. Re programmed to increase the fuel when cranking to aid cold starting . Engine temp measured at the water sender unit . If you have poor cold starting you can fool the computer with a 1000 ohm resistor in series with the sensor and a switch or relay to take it out . This makes computer think the engine is colder than it is. Available as a kit for other JLR vehicles.

 

will that result in the engine getting more fuel all the time ?

As mentioned, you would need a switch or relay to short out the resistor.

 

The kits on ebay were for LR P38 diesels which had a cold start problem when the pump was worn. When the ignition was turned on a relay with a 20 sec timer was activated and at the end of the timer period the resistor was bypassed . Lots of timers on ebay for about $5 I have one to turn my SRS light off !!!!
