Had a service done on my x type by a friend. And I had engine light on for over s year . I asked home to put his engine management box on . To find out and take off if he could .

well picked car up after and indicators ,full beam, central locking inside will only work when they want to 

any ideas please

If hes had it plugged in a while with the ignition on and the engine not running, odds are the battery low

the batteries on the s-type and x-type seem very sensitive and if they get low, cause all sorts of problems with the ecu modules on the car

I recommend you put the battery on charge over night, which will usually cure the problems

make sure you have the stereo codes before you disconnect the battery, you could charge the battery still connected

Batteries, as Joe has said, do play a very important part in the operation of the S Type.

Batteries start to age after about 4 and a half years, so it is worth checking the age of your battery and see it is holding a charge.

Hi Steve

Keep an eye on your charger, My CTEK has a green led on it when it fully charged, then when the battery voltage drops the red light comes on, to show charging, for a short while, then goes green again.

This is a good indicator of the battery state, it should stay mainly green and then just top the battery up every now and then, after its initial charge

if it never goes green or takes ages to go green and then only after a very short time, starts to charge again, then you may have a battery issue or a leakage current draining the battery

depending on which CTEK you have, the lights will be different, but there usually a indicator to show when fully charged, then it looks at the battery voltage, when it drops to a certain level, the charger kicks in and tops it up. so fitting a battery charger on it might cure it, but if there is a underlying fault, it might still be there.

I have CTEK chargers on two of my cars, I noticed recently that every time I went in the garage the one on my mitsubishi, was allways red,charging, and within a few weeks now it never goes green now, to say the battery fully charged, so initially I thought it was the charger, as the car all ways starts on the button, so I swapped it with the one on the jaguar and it does the same, ended up being the battery, the CTEK charger was keeping the battery charged, but when the charger was removed, it starts to discharge and goes flat withing a few days

but saying that, the bosch battery has been on the car for nearly 12 years, so the charger has done a good job of keeping it in a good state.

How long did you charge the battery for?

Did you charge it in the car, or take it out to charge it?

Does the radio work?

I am wondering whether the memory settings have been lost, in the which case a reset may resolve the issues.

you might need to disconnect the battery, to clear any errors, this should cure it

make sure you have the stereo screen code first

if the faults all ready there and you charge the battery, the faults will remain, disconnecting the battery should clear it

if not, there are other issues and you need to get it plugged in to see what errors there are

just one more thing, have you checked all the fuses are good, just in case
