So I thought I'd post and see if anybody could advise me on where to look next, I have an intermittent electrical fault that seems to have come around with bad rain and cold weather, so I have intermittent power steering with the light on the dash, aswell as an engine management light when sat idling the car seems to return to idle slowly when I rev around 2-3000rpm, and the most confusing is the intermittent fuel gauge but only when cornering right, it dings and seems to loose power for a split second snd then go back to normal, along with the my speedo also stops working, I've already checked plugs on the ecu,abs pump and power steering pump, repaired the infamous load signal wire, and removed and cleaned all the earths on the chassis leg, ive checked fuses and literally everything I can think of?? It's a 1.9tdi pd100, on a 57 plate, mk4 I believe
