Seat Toledo turn signal issue

My 2004 Seat Toledo diesel is showing a turn signal error. The speedometer is also acting up, and there's a lighting fault stored. Mileage is at 128706 km.

Summary of the thread

A 2004 Seat Toledo diesel exhibited a turn signal error, accompanied by a malfunctioning speedometer and a stored lighting fault. Initial checks on the flasher relay showed no issues, leading to the suspicion of a bad cable or plug connection. Cleaning the contacts was suggested, but ultimately, a workshop visit confirmed a bad plug connection as the cause, resolving the issue.

Did you check the flasher relay? I had something similar happen on my old car. Worth a look before you start swapping bulbs. Does the error say which signal is acting up?

The flasher relay looks okay. The error is pretty vague, just says 'turn signal problem'. Any other thoughts before I start taking things apart?

Okay. With a vague error and your checks, a bad cable or plug connection is likely. Cleaning the contacts might help, but honestly, those symptoms suggest a workshop visit.

Right. It was a bad plug connection, just like you thought. Cost me 95€, but it's sorted. Thanks for the advice.
