Engine light continues to come on ever since I had car repairs done on 2005 S type 10/14/10 ie front brakes repaired, wheel alignment, oil shield was left down, second time engine light on, Emmission service done with direct injector cleaning, fuelling adaptations reset, codes cleared. Engine shakes, can feel vibration in steering wheel when car is still and during driving. Car also has jolts from the rear when slowing down before completely stopping. The car has been serviced 4 times. I hope you can please tell me why the engine light keeps coming on.Thank you.

check your shields if had any brake work done or check control arms and tie rods ,even tires

I would check the front brakes first, but it probably needs a proper alignment.

Is your oil level low? If your oil pressure is low as indicated by the light, you will do serious damage to your engine if you continue to drive without repairing the fault. The fault could run the gamut from a loose oil pickup, to a bda oil pump to bad bearings.

You don't state what vehicle it is. If it is a front wheel drive, check the CV joint, although this would be more prone to making a noise whilst in a turn.

Change engine oil and replace oil filter.

Inspect tires for wear and rotate.

Inspect brake pads/shoes/rotors/drums, brake

lines & hoses, and parking brake system.

Inspect wheel ends for endplay and noise.

Inspect engine cooling system and hoses.

Inspect exhaust system and heat shields.

Inspect steering linkage, ball joints, suspension

and, if equipped, half shafts, driveshaft and

U-joints.

Replace engine air filter.

Replace fuel filter..

Replace cabin air filter, if equipped.

Change automatic transmission fluid on vehicles

equipped with the Torqshift and 4R100

transmissions. Replace the remote filter element

on the vehicles equipped with the Torqshift

transmission. Inspect automatic

transmission/transaxle fluid level on all other

vehicles, if equipped with dipstick. Consult your

dealer for your particular requirements.

Change automatic transaxle fluid and filter on all
vehicles equipped with CVT.
