Hi
I bought a new V7iii Stone mid March 2020. Check Engine Light has been coming on for past 4 weeks. It also loses power and stalls sometimes when coming down through gears to a stop - not every time but just sometimes. Dealer service dept checked and thought it was problem with Lamda sensors but has now done full check and in conjunction with MG decided it needs a new ECU. It is under warranty but as a new MG owner I just wondered whether anyone here had experienced similar problems and if so whether replacement ECU fixed it. Or did it turn out to be something else. Thanks Alan

Sounds like a disappointing situation Alan, others will have better knowledge but I wonder if the initial diagnosis was a poor guess -- Lambda sensors have a fairly minor effect when they work, and even less when they don´t.
Diagnosis is often difficult and expensive, simple replacement can be cost effective and preferable. My suggestion is that if the dealer is going to replace parts ´til the fault disappears, do remind him that the bits he removes should be returned to you, and mark them indelibly if possible. You might at least get a few spares out of it. Best of luck.

I doubt the dealer will hand the parts over if the bikes under warranty they usually have to be returned to the manufacturer

That may well be the actual case Chris, though I would have thought the parts would belong to Alan since they are bought and paid for ? And why post faulty parts?
Not that my logic usually prevails ...

No, if parts are replaced FOC under warranty, then they have to be returned to Guzzi, otherwise the dealer gets charged for the new replacement.

When I was working at a main dealer for cars, I used to look after the warranty claims.
I would need to retain the defective parts at the dealership,, as every few months the factory sent a rep round to check whether the defective part was actually defective . Once he'd signed it off I could dispose of it.

I know one large Guzzi dealer (now no longer trading) who had a big bill from Piaggio on one occasion because they hadn't been able to return parts within the timeframe allowed. |

Thanks all for replies. To be honest just hoping it’s not one of those issues that drag on and on.
