A4 B6 1.8t.
Ive had a miss fire problem at high power for a while now, done all the obvious things (all coil packs, all fuel injectors, plugs, emmision hoses, fuel filter etc) and now suspect the fuel pump.
Downloaded VCDS-lite, connected ok, read the vaults (below), problem is I hit the clear codes button while the engine was running and it immediately coughed and stopped. Now the fuel pump doesent deliver any fuel at the rail. Question is, how does the immobiliser work, does it kill the spark or fuel...... or both?
So far Ive managed to fix all previous problems with the help from this forum, but not his one, any help would be appreciated.
