My 1.4 TDI 75 A2 has once or twice shown a 'misfire' whereby the engines seems to be running rough, poss on two cylinders and this seems to be related to damp conditions.
Upon investigation there is a round electrical connector with 4 wires which goes to the top right hand side of the cylinder head /cam cover(as you look at the front of the car) if this is 'waggled' the engine will go back to normal / reinstigate the issue. Could someone explain what this connector actually controls? senses? goes to? Has anyone come across this before.
In addition to this there is a warning light which comes on which i believe is actually the traction control light. Any ideas? what exactly this is. Im almost certain the problem lies within this connector / small area of the wiring as it can be made to go away by agitating this connector. As other than this the engine drives fine.
One further question i have is on the left hand side of the engine bay there is a unit which has some silver corrugated pipe work (looks like aircon ducting but it isnt as i havent got aircon) going into and from it. One of the pipes is clipped down to the very bottom of the car and doesnt appear to connect to anything? any ideas what this is and whether it is normal for it not to connect to anything it has a jubilee clip on the bottom. Theres no obvious place for it to connect and it is causing me no issues.
Many Thanks In Anticipation.
