Re: New Croma - acceleration problem

It was siezed open enough to see daylight through it! Maybe EGR should be stripped down and cleaned at service - something to think of all you multijet owners with no EGR valve issues.

Re: New Croma - acceleration problem

Begs the question what happens if you disconnect the EGR. Dash warning almost certain but what happens to the performance. ECU limp mode or business as usual.

Also, for those who exeprience poor performance with no dash warning is/are minor fault codes looged in the ECU.

If / when I hit this problem I'll try to remember to post back what I find when I use my scan tools.

Please let us know what happens if you blank it off instead of disconnecting it...I for one would be very interested

Re: New Croma - acceleration problem

Mine was terrible yesterday, quite embarrassing not to mention slightly dangerous trying to go right on a roundabout... must book in to an understanding garage.

Re: New Croma - acceleration problem

My is back and running fine for now. I do need to replace my EGR as it will clog up again. I'll get my EGR valve replaced once payday arrives.

Re: New Croma - acceleration problem

Just been to the local Fiat\alfa specialist MGC in Nottingham, had a long conversation re the acceleration problem, they said it could be one of two things a leaky turbo boost pipe as there is a nut that rubs on the pipe that will eventually make a small hole. They had a quick visual inspection and said it was not that then agreed it was the EGR valve, they said that they are usually replaced with a reconditioned one and exchanged.

After ringing round FIAT, Alfa and Vauxhall dealers to get hold one it would appear they are difficult to source and are on back order,. but the Alfa dealer had one coming in. The price varied depending which dealer they went to. They quoted an hour to fit, total price about 170 inc VAT.

So if you want one get your order in early...

Re: New Croma - acceleration problem

Just been reading with interest the lack of acceleration thread. My last car before the Croma was a Marea Weekender JTD105. This had a problem 3 times with lack of acceleration. I took it 1st time to a locally recommended auto electrical chap who hadn`t seen under the bonnet of a diesel Marea before. When I described what the problem was he connected his diagnostic screen up to the plug on the car and it came up with a fault number which said it was the ERG valve. However he was not convinced as he had had some Vauxhalls and Renault diesels which had come up with a similar result but even changing the ERG had not cleared the original problem. He then took off the air volume sensor between the airfilter and the turbo intake it was only an electrical resistor with coloured bands on with the wires either side of it showing distinct corrosion. Changing this solved the problem. I had the problem twice more always in the spring after winter weather had done its dampest! This problem must be well known to Fiat as the part is now an exchange part.
One good hint is to change your air filter in the autumn this has meant I had the last two winters without the sensor probs and my son who now has the car has had no problems after the last winter. I hope this is of help to anyone who experiences lack of power . also you can get a lot of air filters for the price of one air volume sensor !!
PS I have been told that the ERG dumps the turbo pressure to the manifold to protect the turbo seals during decelleration , I think it would be foolish to blank it off .

Re: New Croma - acceleration problem

I have had this problem myself - twice! The first time was a problem that grew incrementally over a period of time. This turned out to be the EGR valve. The second time was rather sudden - I pressed the "go faster" pedal and... it didn't. This time it was the gasket on the inlet manifold. Bother! Got both fixed under warranty at the local Fiat garage.

Re: New Croma - acceleration problem

I'm joining the Croma owner's gang tomorrow (picking up my 1.9 prestigio from a dealer).

Just phoned the dealer to check that everything's ready for tomorrow, and he says they've taken it to the local Fiat dealer as a light was lit on the dashboard. It's having ... a new EGR valve. Will still be ready for tomorrow though.

So I'm glad I've got this issue dealt with before I even get it - I was a bit worried having read this thread. I'm very impressed with the dealer though - it's still under manuf warranty, but it doesn't apply as I haven't yet transferred it to my name, so they are paying the Fiat dealer to fix it (he said about 200).

So hopefully I won't have any more EGR issues if it now has the new improved version.

I wonder if this is why the previous owner got rid of it.

Re: New Croma - acceleration problem

Turbo waste gate deals with overboost surely?

Check the drive for rattles and knocks over bumps, and check the lifetime on the brakes - they've expencive things to replace.

Cheers, will do, although wouldn't the odd knock or rattle be expected with the 18" wheels? The one I have already test-driven seemed a bit harsh (but acceptable).

It had new brake pads with a service, not sure about disks though. Are the brakes that expensive if you hunt out Vectra or Signum equivalents?

Sorry, gone OT for the thread. Thanks for the buyers advice though.
