SOURCE: x-type jaguar automatic (gear box fault)

I have a 2002 X type (2 litre. done 44000 miles), dash showed gear box problem, (red circle light up). I pulled out and turned the engine off. 5 minutes later turned the engine on. The engine running but the car would not drive either in drive or reverse. Turned the engine off again and on the car driving but not much power. The care is taken to the Jag. dealer and told is misfiring + some gear box faults. Suggesting to change some coils and see (cost about £200+). also possible need to change the gear box costing about £2500+. Please advice. Shall I go ahead with the repair? Should I part exchange.

You must have a fault code test run first, that is the start point on all modern systems of engine control.

1.9 dti opel pick up wont start


It could be an Immobilizer fault, if the spanner /car light comes on.
If you have a spare key, try it
A Flashing spanner light normally means immobiliser fault hence the non-start. The spanner light left might just be an indication that it has stored the "wrong transponder" code.
Opel will have to clear this but you might need a CIM as well that is the bit that reads the key to allow it to start.
Try the spare key if you have one

On 1.7 DTi models, a defective solenoid in the pump can cause failure of the ECU due to excessive current draw causing components to burn out. but this *should* cause other fault codes to appear.

Engine light came on after car wouldn't start in the cold


It sounds like a fault in the display board inside your dash. Is the car running normally now? If so, wait till weather warms up and see if the 8 turns back to normal.

Vauxhall astra 1.8 auto will change up the gears starting off but when in d4 wont change down have to put it into 3 2 1 manually aalso the light with the spanner is on


take the vehicle to your local fault code reader and plug the vehicle in to diagnostic equipment and go into the gear box control unit just like the E.C.U but for the gear box this should tell you any faults if this does not come up with any thing then try draining the oil and refilling with fresh I have known auto boxes play up just from old box oil if you are saying you hav a light on the dash then to save your self time messing with gear box oil (witch has a really nasty smell) get it plugged in first to eliminate electrical faults first hope this help good luck

Check engine lights are on
