S6 timing

Awh Rich, FFS !

While unfortunately it won't do you much good, you definitely have my sympathies.

Wishing you the best going forward.

Sorry to hear that too!

The weekend I took it up there my house was broke into and a substantial amount of money taken so even if it is cured the car will be for sale. I have little interest in the fault at the minute.

Wow. Sorry to hear that.

Okay, did it go in on the 21st? If so, what was the diagnosis? We need to know.

Bump.

[UrS4boy]

It is still going in on the 21st

Another thought for Rich.

Have a look for anything physically loose on the motor which could be tapping or banging against the head or block manifolds which coulds be mistaken for knock by the ECU.

Yes, I had some good spares on a B5 V6 loom I was given, these would do the trick too..

Last night I had a real close look at the engine wiring harness again and I found 2 broken pin carriers in 2 of the injector connectors, the plastic was just crumbling, the female pins were not being held in the right position to mate properly with the males. Replacing the connector housings seems to have solved the issue, hopefully I'll have time tomorrow to log the car and see if I've eliminated the problem completely.

Andy P. had that same problem.

Could be a red herring but I've had some of your symptoms on the coupe since doing the 3B - ABY pin-swap and 5 coil ECU mod. At the same time I changed injectors and software so it was not easy to track down.. What could be wrong? Coils, injectors software, all changed.. What we knew for certain was that the ECU was detecting knock and pulling timing but not always doing it. At half throttle the car drove better than at full throttle and really didn't like full throttle below 4k5. The car drove much better when cold than when hot.

Yes both. Checks out well in the 'good' range. It's also the way sometimes the power all comes back like a switch has been thrown. Not the way wear works.

Leading on from what John has said, have you verified the mechanic state of the engine via either a leakdown test or comp test? Guess we have been precoccupied with sensor/ecu issues.

I've asked this before but is there anyway I can stop them pulling the timing JUST to prove?
