Hello all Alfisti,
Atoll blue 145 running like a dream and was able to garage for worst of winter,which seemed a bonus,but battery has not lasted even though car was started weekly.
This has led to what i think is an electronic key fault leading to immobilisation. I hope this is a common fault as I do not have maroon key although code doesn't seem to help. All that comes up on diagnostics is U1600 electronic key.
Do not want to go main dealer route as cost would be prohibitive I reckon. Is this caused by battery going flat and can I rectify it. How would be a massive help,any help or suggestions greatly appreciated,cheers.

Maybe you have to take a look at the BBoB, maybe CODE inmobox isn't being fed properly..

yeah, maybe...

have you checked for spark, fuel pump voltage and do you know if the camshaft position sensor is good..?

I would want to KNOW about those three things before being certain it was a key fault.


As it's a very, very rare thing to happen...

didn't know there was another one of us in Scotland- good to hear from you!

Ok cool,

Yeah- sorry; I don't mean to 'laugh off' the info you've pulled out already,

But those things I mentioned are BIG failures, and are entirely plausible (maybe not the fuel pump- but I'd still want to know)

If it was MY car, and I already ad the info you describe, I'd want to PROVE IT, first.


I've had a few Italian cars, and the problems are always simpler than you imagine them to be. In all the issues I've ever had on about 15 (?) cars from this era- I've never had a key-programming fault...

Out of interest - are you getting the CODE warning lamp on your dash as well as the U1600 error?

As Antonio asked, have you checked the relays located next to the battery? They are normally the first cause of the car being immobilized and the CODE like on the dash. Check all the relay connections and the connections to the wires on the bottom.

Failing that, ensure that the fuel cut-off valve has not been activated by checking that the button under the passenger seat (from the front side) is pushed down.

CODE warning light is coming on dashboard as well (forgot to add that) and problem has only started after battery was changed. I work in catering and the way my weekend is looking it could be next week now till I get a chance to double check all connections etc,expect to hear back from me on Wednesday,any thing else I should check please let me know.
Spark,fuel pump,voltage,camshaft position all good as well as fuel cut off valve,at least it's not them,cheers.

Ah, well; that's interesting

the battery being changed would certainly hint at a possible dunt to the BBoB relays position, as that's RIGHT on it, bracket or not.

Maybe this is very simple after all...?

9 times out of 10 it is the relays.

Hello again to all,
have checked all wiring,relays,connections,fuel pump,fuel cut off,fuel is in it and I'm coming up blank. Car sounds like it wants to go,strong turnover etc,but code light still on dash after checking and double checking everything I could think of.
Is there an alternative way to by pass immobilizer remembering I do not have master key,thanks.

Hey Hiltz-

unless i'm daft-as-a-brush, I think you could say the GTV and 145.gif / 146.gif systems are identical.

Or at least 'the same', if not identical.


Is that magazine a 'club magazine..?
