I thought it might be useful to have a thread to post problems encountered on your Mk4 Ibiza to see how common they are and if they have been successfully solved, preferably under warranty. I thought it could include the car model, the problem, the symptoms and then the action taken to cure the problem and was it a warranty claim. Here's my list so far: 04 Reg. FR TDi. Recall for fuel pump bolts. Replaced under warranty but this caused a fuel leak which was then cured at the second attempt. New brake light switch. Glowplug light showing on dash. Warranty fix. New ABS ECU. Power steering light showing on dash. Warranty fix after 1 week wait for parts. Fuel gauge stopped working. Warranty fix of broken wire in footwell. Creaking rear suspension. Lubricated under warranty but ongoing problem when roads are salted. Door seal round window replaced. Excessive wind noise. Warranty fix but badly fitted and did not cure problem. Misting in all lights. Removed bulbs and dried out headlights myself. Comes and goes with atmospheric conditions. Would not fix under warranty. Various trim rattles. Fixed myself with varying degrees of success. Over to you now.
