Second problem is I noticed a small drip coming from the side of the sump nearest the front of the car. It's not oil however, it looks and smells much more like DERV. It's just a little drip that seemed constant when the engine was running.
What can of worms have I opened today? Original check positive but three other faults found (check my other thread for the third fault). I guess the poor old girl hasn't enjoyed the 30k I've racked up in her over the last year...
