Final update.
Drove down to Halfords to get some bulbs and their unhelpful computer didn’t have which type are the correct ones.
Decided that now it’s stopped raining I’d go home and wriggle under the car and remove one of the bulbs. But before I do that I thought I’d give the lights one more go.
They work! Can only presume change took place after starting the car properly, rather than just switching the ignition on.
Key points from this;
Turned out to be very cheap and easy to do. £25 for the cables and £45 for the
MES software.
Unsurprisingly, Fiat are unlikely to build cars with different looms. The main loom is going to be standard and the various options will link to that. Wife’s car is a 2010 and connection was present.
Auto Electrician did not have the correct software even though he argued he did.
Fiat Dealership, this was a 5 minute job your mechanic should have been able to take care of. Instead they spent longer arguing the ECU would need to be changed to accomplish this, rather than just trying it. Only plus side was they didn’t charge me the £70 standard fee.
Thank you to all those that have helped me with this thread and those that have posted previously on
MES software.
