vauxhall astra fault diagnosis

wolfehouse

our 2005 automatic vauxhall astra went into limp mode and transmission/electrics warning light came on

this has happened before and was a loose switch (near the accelerator) that the rac man jiggled and fixed for about 8 months.

same happened again today but when the rac came out they could find no fault. but he suggested we 'get it diagnosed' which will take 11/2 hours and cost a huge amount, i'm guessing.

should we take it in to the diagnosis place anyway? anyone know what would be likely to happen if we did?

thanks in advance.

phone a couple of local garages and ask them how much they charge for a computer check. around here they will charge you about 30 - 35 quid to plug it up and tell you what the computer says. it takes 5 minutes for the computer to read the problems

This. Try and find a local independent vaux specialist if possible. Avoid the dealers as they will rip you off for the diagnostic as you say. Our local independent vaux specialist did a computer diagnostic for free on our old corsa a couple of weeks ago.

do the pedal test.
accellerator to floor , brake pedal pressed.
turn on ignition but dont start.
the engine management light will "flash " you the fault
have a pen and paper ready
it is a 4 digit code
the first digit will flash and then there will be a short pause b4 the second digit and so on
1 flash = 1 , 3 flashes =3 , etc (10 flashes = 0 )
if there is more than 1 fault it will do them 1 after the other until they are done
add letter P and letter O to the beginning of the code (eg . PO0335) and post on here and I will look up the fault for you

Could be the switch on top of the gearbox. Quite common fault and easy to replace.

One small test to do - put the ignition on, but dont start the car, put it in reverse and have a look to see if the reverse lights come on. If they dont - check the fuse for the fag lighter. (Sounds strange I know...)

reverse lights come on ok
no lights flash at all- so no code to post

should i still take it in for a 'diagnosis' or does this mean nothing would be found anyway???

did you have brake pedal fully pressed to the max cos it wont work if you dont . if you did , no fault will show on diagnostic machine

wolfehouse

Pedal pressed down hard. Still no flashing.

crankshaft position sensor.
Probably the most common fault code.
Misfire, limp mode, poor starting, then eventually it won't start.
Use a genuine vauxhall replacement, copy parts aren't very reliable.
