Code U016A

U016A code

Twice in the last week or 2 (I dont drive it much) my 2015 ST180 has had an issue starting.

The first time it cranked once more than usual (not major but I noticed it) then second time it cranked twice no start and there was buzzing from the dash for about 2 seconds, tried again same issue, tried once more and she started.

The second was after filling up so I was thinking evap but I scanned the car no codes, scanned it while driving and it threw a U016A. No EML or nothing. Cleared the code but it came back so it’s persistent.

Happens 1/10 times if even. Tried my mechanic, auto electrician even motor factors specialising in ford. All either didn’t know, couldn’t get the car in for a month or couldn’t get the car in for a month and wanted to charge 150€ to scan the car because my “scanner isn’t good enough”.

Battery tested and is good.

Im looking for ford specialists in my area but they’re few and far between so I ask all of you great people: Any ideas?

Although the code says contact is lost with the GPS module and it leads you to think that the GPS module is at fault, nothing much should happen if the GPS module goes on the fritz except navigation stops working. However the code says Lost Communication. The module communicates across the CAN Bus, which is where a lot of other stuff communicates that could affect the engine. It may just be that the GPS Module is the only one to complain so far. Here's a page about diagnosing the problem and possible causes. https://www.obd-codes.com/u016a
