The indicators on my 156 (Facelift S/Wagon) have packed up and I'm pretty sure it's the relay.
After searching through some posts on here I've discovered that it's located under the steering column but on the facelift version it's obscured by some bits n' pieces and requires removal of the steering wheel to get access
Anyway I phoned the dealer and he didn't have the part in stock but was going to check round the country for me. He seemed a little doubtful that he would find one though.
I'm guessing that relays are relays and I could get one at any motor factor but the dealer could only give me a part number (156034618).
Do any of you good folks happen to know the details of said relay so I can ask around local motor factors?
At the moment I'm doing hand signals but that's only any good if I'm turning right!
