run the fault codes as the engine light is warning you of potentially expensive problems if you continue to ignore the warning The ECM puts the car in limp mode to help protect the engine and transmission form damage but if you continue to play at fixing rather than going to a specialist shop and have the codes read to really fix the fault it will cost you big money

For the money you spent on another computer, you could have brought your car to a qualified mechanic and had the problem correctly diagnosed and repaired. 'Restricted performance' meant the computer saw something wrong in the engine, and restricted the performance to keep from destroying the engine. You killed the messenger and still have the same problem.

Hi! Only one thing can cause this. The coolant reservoir is not sitting on the right level. The coolant should be filled and sit only on the max or full level. If its above the right level it tends to overflow. HOpe this helps and thank you for using FixYa!

There are Valet keys (often with a green knob) that will
only unlock the front doors and the ignition but not the
glove box nor boot/trunk.

When either the front door locks or the console button is
pressed, all the doors should lock. Likewise, when either
front door is unlocked, all the doors fuel filler lid and if
selected, the boot will also unlock.

Boot lock has three positions. Unlocked to the left,
automatic with the doors in the center, always locked to the
right. Simply remove the key in what ever position you desire.

The locks can get confused and not work correctly. Simply
sit in the car and manually lock all the doors. That will
usually get the locking module sane again.

what does t11 means, is this on display, or by diagnostic tool

take dash apart and renew the bulbs

You can do a fluid and filter change on it. Over time tranny fluid gets pretty hot and can burn up and not be as effective. Clean fluid can make the world of a difference when you catch it early enough.

Another thing I recomend to a lot of clients and use myself, is Lucas Oil, tranny treatment, it is just a bottle of fluid you dump in the tranny and it reinforces the old seals and inproves lubrication under most conditions. You can buy a bottle of it at just about any auto parts store, or even Walmart for about $15.

Best of Luck....

could be a weak battery. they tend to make electronics go haywire when there is less than desirable charge left on a battery.

the gas gauge is not related, that would be a defective gas gauge sending unit in the gas tank, the check engine light indicates that one of around 200 poss faults has occured in the electronic engine controls, you will need to have the OBD 2 engine control system tested for the fualt code that is stored when the light is turned on.
