I recently purchased '06 Brera 2.2 JTS with manual gearbox and 90000 miles, mainly for its looks, not interested in performance or a real sports car tbh.
Basically in 1st and 2nd gear the acceleration is so erratic it makes the car feel like it's driving over some bumps then suddenly it picks up and is away and is OK at the top end of 2nd gear and ever after into 3rd gear, etc.

I've read a few posts here and there from other Brera owners who've experienced this same issue but I wondered if we could collate the solutions here. They suggest remapping, new exhaust or even new clutch.
I've contacted a local remapping firm and they want £349 to remap from 185 to 211bhp, hardly sounds worthwhile and I really don't think I'm even getting 185bhp any way.
I've seen some quotes for new clutch at between £1000-£1500, is that about right?
The car has prodrive exhaust so I don't imagine that's the issue.
How can I tell what the problem is? Do I need to book it into a Garage to find out or are there some giveaways to look for.
Has anyone had any real success with this issue and what was the solution in your case?

Hi, I hate to say but it could be heaps of different thing causing your issue. Rather than a remap as you mention, which is more fine tuning, your symptoms sound more like something fundamental like faulty coils or plug leads. Probably electrical rather than fuel related. Best to take it to a trusted local indie garage than start spending on random parts. Good luck.

Sounds like misfire to me when you describe it as like going over bumps. As above get it diagnosed by a specialist as that will work out cheaper than throwing some parts at it.

I wouldn’t be suspecting the clutch also I wouldn’t be mapping it until you know the car is running right.

I have the same problem as well. To test if the cause is the link you posted about the hesitation issue, I'm trying to remove the back boxes completely. The nut holding the boxes is a bit rusted though lol. If that's not the problem, then it might be the carbon buildup on the intake valves so cleaning those will be #2.

Thanks for your advice all and speedy responses! I'll get it booked in for diagnostics (apparently £120 + vat) and feedback here the final outcome in case anyone that helps anyone else.

That diagnostic quote is a bit tasty my Alfa specialist charges £60 plus vat I know prices vary from area but double?

Yes, I agree. They want £40 to plug in and get fault codes, then £85 for an hour's investigation.

I'll look elsewhere upon your advice!

Rather than pay for your diagnostic why not buy your own OBD reader? the dirt cheap Ebay ones are a bit hit and miss, I bought a Panlong mini OBD11 works a treat with my dash command app on my iPhone via WiFi.
I leave mine plugged in all the time as there a bit tight to get in and out and this particular one doesn’t stay connected after the ignition is off so no battery drain.
They are handy to give you an idea what’s wrong when it when it throws a light up and with the wealth of knowledge on hear with some of the guys it’s a real help, as I only do shall we say the less demanding DIY jobs on the car it’s still a great help to know what to expect at the garage.

That is rather expensive, just had my beemer in at a highly regarded specialist they charged me £72 for plug in for software update and some investigation work.

Defo spend a bit on diagnostic gear as you can use it over and over then saving yourself a fair few quid

Elm lead with some coloured adapters about £20 then MES download for free but it has limited functions. Paid for the full version think it was £50.

I've managed to get an ELM327 OBD2 bluetooth adaptor and have installed Torque Lite ( for now ).
There seems to be loads of metrics available, do you have any tips on which ones to have running whilst I drive the car to help understand what's happening?

I would check basic components as well. Condition of spark plugs, air filter, throttle body could be quite dirty. When I get a new car I tend to fit a new air filter, clean the MAF sensor with MAF sensor cleaner, check and replace spark plugs if necessary and clean the throttle body with throttle body cleaner. I also chuck a bottle of injector cleaner in the tank and run some premium fuel if it does not usually run premium. Not sure if injector cleaner helps JTS engines much being direct injection though. As suggested earlier on you may have excessive carbon buildup on the intake valves due to the direct injection.

Thanks Mikesalfa, that sounds like sage advice. The car was garage-serviced not long before I bought but even I question what these garages actually do during a service.

I have an update for anyone following this thread (or for future): I filled up today with BP Ultimate petrol where previously I had filled up with the Asda lower-grade and almost instantly as I pulled away from the garage the issue was gone. The hesitancy is still there between 1700-2000 revs in 1st and 2nd gear but nowhere near as noticeable and the power curve everywhere else is a lot smoother too. Not sure I'll need that remap after all but will know more on Monday after some diagnostics have been carried out by Autodelta. Will feed back here then.

The engines are not awfully fond of the lower grade fuels available. Use them in an emergency, but ideally not the whole time.
