Car won't start

[jimyboyle]

My car is a 1997 2.5.

There is a problem with the near side door lock microswitch and i have a new one to fit. This morning when i unlocked the car the horn beeped twice and the central locking was continually locking and unlocking. It has done this before. (but always started first time)

When i tried to start it all the dash lights worked and the engine turned over fine but made no attempt to start.

There is some of the usual dampness behind the seats but no water and the electrics below the seat are dry.

I left it a while and tried again. Now the central locking is OK, the window drops when I lift the handle but it still won't start although the engine spins fine.

Would the microswitch in the lock affect the starting and if it is the alarm unit getting damp would the engine still spin?

Some time ago the engine check light would come on occasionally which the independent specialist reckons is a fault with one of the vario cam units but the car runs really nicely.

Anyone got an idea where i should start to look

Ywo beeps means there is a problem )more than an open zone - which one beep) with the alarm system.

You will need the Durametric software, a PST2 or PIWIS tester to diagnose it further.

Jim:

Normally, if the immobilizer under the seat goes bad, the entire starting circuit is disabled (i.e., the starter will not be actuated and the engine will not spin).

Nonetheless, if you suspect the unit is getting damp, it would be good practice to open it up and use a hair dryer so as to prevent possible corrosion of the circuit board, etc... Also, double check that the fuse at the rear of the unit is ok.

Changed the door lock and now no more horn beeps on locking or unlocking, didn't help, still won't start.

Alarm unit is nice and dry inside, no sign of any dampness so it looks like the Porsche Centre after the holidays.

Don't forget to check the fuse on the immobilizer as Maurice suggested. Also try fussing with the clutch switch as it sometimes sticks and that would cause the car to not start.

I did check the fuse it was fine and its a tiptronic.

Ive been away since sunday and when i came back today i tried it and it felt as if it tried to start so i put the battery on charge for 5 hours,

although it was still cranking the motor fine.

Its a 911 sized battery so i reckoned with a full charge i could really give it a try.

After about 10 minutes it burst into life and idled as if nothing had ever been wrong.

I will still get it checked out after the holidays.
