I recently tried the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my jcb 3cx site-master. It would'nt move forward or reverse, engine was good both solenoids for forward and reverse worked, but still couldn't diagnose the problem. I don't have much technical knowledge but I just followed it step-wise, and now it works perfect! covers wiring, codes, diagrams, torque specs, PCV, everything got it from www.reliable-store.com

The first thing to do is have the Airbag system scanned for fault codes. The code will point you to the problem. Have you had any front end damage repaired recently? If so check the wiring and/or the impact sensor. If no codes are found, replace the clock spring under the steering wheel, following all appropriate safety instructions.

You could have something wrong with the computer causing the error message on the scanner. Do this connect scanner and turn key to run don't start vehicle. See if this give you error or code. The backfire is caused by gas getting into exhaust system. You could have a wheel locked up causing the abs light to come on.

Could try disconnecting battery for a few minutes.

And the codes were...?
The ESP gets input from a few sensors - ABS wheel sensors, yaw sensors, MAF...
If the 2.4 has electronic throttle (it should), then there shouldn't be any form of actuation in the footwell, so can't help you with that one.

The lock shift solenoid that works withe break pedal has gone bad... it's located next to or In front of the shifter.. on some vehicles. You have a key slot that you can use another key or small screw driver in it to unlock the shifter. Just replace that and it should be fine..

In back side of the radio, (for Audi A4, A6 - year 1999), you will find a blowed fuse = 10A (red colour). Replace it and that's all. Also:
IMPORTANT NOTE: You must have the security anti-theft code for yours Audi Concert radio from the car manufacturer! For Audi Concert the sequence of programming is:
1. Push simultaneous "SCAN" and "RDS" keys until on the screen will appear "1000" displayed.
2. Release keys. No more push on "SCAN" and "RDS" keys because otherwise number "1000" will be considered as first safe code attempt.
3. By the #1 key you will set up the first safe code digit.
4. By the #2 key you will set up the second safe code digit.
5. By the #3 key you will set up the third safe code digit.
6. By the #4 key you will set up the four-th safe code digit.
7. Then push again simultaneous "SCAN" and "RDS" keys for confirm this safe code. On the screen will be displayed "SAFE" notice. Release keys! For few seconds a radio frequence will be displayed. The radio is now ready for use!

You may have a wiring harness problem there, Kjell. Do the door locks work from each individual door? Many vehicles have two fuse boxes - one under the hood and another inside the car somewhere - typically on one side or the other of the dash. Consult your manual. If you don't have one, get one. you need it now, and you will inevitably need it later.

What are the problems exactly. You are being to generic.

Hi Jeremy! WOW! thank you very much about your tips!! I fix my airbag light just moving the yellow wire under my driver seat at NO COST!! I got Captiva LX 2007 and the airbag lights on for month and I know Holden dealer charge a lot for any repairs! Airbag light on - fixed now!! Thanks again! Now i need to fix my Engine light - Holden dealer quote me for 4K-6K to replace the timing chain.. I got quote from the local mechanic for $2400 ---- a lot cheaper!! Cheers MItz

Hi.your interior light switches is in your door locks so it can be that your drivers door lock is faulty or the wires in the door is broken the wires runs in a rubber like tube there where your door hinge is you have to open the tube and check wires if its ok the chances is good you are going to replace the lock.hope this helps

possible but I would be having a load test on the battery as the indications are that there is a bad cell or dirty/loose terminals

its a scandinavian version ,,,the lights automaticly come on .

Any specularion on amount of damage is pointless, you need ro take the head off and inspect pisons and valves. The valves may appear ok but if contact has been made with a piston, you will know this by obseving pitting on the top of the piston where the valve has hit, will probably mean bent valves. There is a second point, I do not know if this is a safe or an interference engine. If it is a safe engine the valves will not overlap with the pistons at any point, they will not occupy the same space at any point in the combustion cycle so there will be no damage in this eventuality. Safe engines are, however, few. I might obtain a used head from a breaker is there is too much valve damage.

I had a car that did exactly the same., replaced the distributor cap and all leads, sprayed thee cap with a waterproofer...problem solved. See link below for a more thourough explanation

before considering a transmission there are some simple and cheap things to do first run the fault codes to find faulty servo/ solenoids pressure test the transmission to find internal faults change oil and clean the filter adjust bands and clutch packs while the pan is off check replace park pawl if you do some or all of these suggestions then you will get a good idea of the condition of the transmission so as to make an informed decision remember the more quotes you get the better and only deal with an accredited transmission shop that offers a long warranty for the replacement box or work done.
