Hi my 1997 2.0 Diesel Sharan wont start. Had no issues until

Customer Question

Hi my 1997 2.0 Diesel Sharan won't start.
Had no issues until yesterday when i came to start the car and it wouldn't start (Had started in the morning fine). Jumped from a friend and started fine. Made a 1hr journey and had the battery tested on the way which was showing 82%. Car started fine and made a further journey for 30 mins. Car again started fine and wen't home. 2 hours later and the car wouldn't start although did try to turn over. Charged battery overnight and now the clock has reset which leads me to belive there at some point was no power in the battery althogh connected to a charger.
Now there is just a clicking sound when turning the key?? All the dash lights come on fine and all lights etc seem to be working fine.
Many thanks in advance - Chris

If the car's not cranking then first check it can turned over by hand so double checking for any mechanical issues

If OK then check that the main battery cables are on tight and the terminals are clean and bright. Do the same for the engine / gearbox earth strap.
Then follow the main positive lead back to the engine and down to the starter motor, and check the connection at this end as well.

There should also be a small wire to the motor which should have 12V when you're turning the ignition switch to crank. If the 12V isn't there, check back along this wire for damage to the insulation or corroded connections

This 12V feed comes directly from the ignition switch so this may be faulty and need replacing

Check the resistance of the main positive lead that runs down to the motor as anything more than a few ohms and it should be replaced

Don't forget to try a jump start from another car / battery as its possible the battery is poor, if you have a voltmeter a healthy battery should read 12.7+V

also try substituting the battery for another as I've known a very flat battery to drag down the system voltage too far even with jump cables

one other thing to consider is that the immobiliser is faulty and preventing the starter from being enabled - however if the dash / ignition lights are on then this usually means that its off

If this is all OK then its possible the car needs a new starter motor
