My starter failed at the Weekend (ignition lights and electrics all working but not attempting to start on correct key position), did all the pre-checks ie. Battery fully charged, terminals and earths tight, spare key to eliminate immobiliser, etc. But after removing the alu re-inforcement Panel under the car and twatting the solenoid it started to work again confirming the (Original 2003) starter is at the end of it life.
Stuck it on the 4 Point lift and started the procedure to remove it, Remove the Black Vacum Thing and the fuelfilter shield for Access and then disconnected the 13mm positive terminal and the 10mm cable from the starter. The lower attatchment bolt was also fairly straight Forward using an E12 TORX socket with a 1/2 Inch drive and a knuckle and a few 6 Inch extentions this alows you to remove the lower torx bolt that has an attatchment bracket for some electric cables.
Then the pollen filter housing COMPLETE is removed as well as the lower Panel under the pollen filter which is a Torx 27 (X2) and some quick release fastners. that will give Access to the upper starter attatchment Bolt.
!!!!!!!!!! USE THE CORRECT TOOL AT THIS POINT!!!!!!!!! An E12 RING Spanner!!!!!!! (Do not be tempted to use anything else as if the Torx head is even slightly damaged you will be in a world of SHIT).
Yes I used a 10mm ring (as I only had an E12 socket that I could not use due to lack of space!) and it damaged the head, I scourced an E12 Ring spanner eventually but it would not fit and you have NO ROOM to batter the Thing on with a hammer.
After some welding of Tools to the head of the bolt I got it loose but it was (A FOOKING MARE!) the alternative was Motor/gearbox removal.
Please learn from my mistake, use the correct tools
(I have not finished it yet as it had my blood pressure at Boiling+++)
