Guilietta 1750 Tct - Engine management light after remap

498 Views 15 Replies 4 Participants Last post by  wbanham
Hi Guys, Apologies if this has been discussed in another post.

I have a QV launch Edition. I have recently replaced a oil pressure sensor as it was repeatedly beeping when decelerating especially when cold. Once the engine was warm it never came up again. After this was fixed I got a stage 1 remap done by an alfa specialist in Cheshire. After a week I had an engine management light come on sending the car into Limp mode. They have checked it and apparently it is and error with the engine timing. Could this be caused by the remap? The guys who did the remap have advised I need a new cambelt but it was only replaced about 12000 miles ago.

Is this something that could be caused by the remap or just a bad job done previously?

I am just concerned as I haven't seen this issue before the remap.

Do they have a website, this place? Have they done any TBis before yours?

Remap as opposed to chip box is better when done properly. However you can mess it up too, then it's much worse.
If in doubt or lack for reliable place, Novitec Powerjet seems a much safer bet.

What's the error code thrown?

Hey SmOgER, thank you for your reaponse. Zaviz Performance Tuning - HRG | Heath Road Garage

They are a Alfa specialist and yes they advised that they have done a few QV's before mine.

Didn't get the code from them just got told that it was the engine time that was slightly out. I am going to try get a local mechanic to run a diagnostic so I can double check this is the code being given.

They have replaced the oil pressure sensor but I am still getting the warning beeping today. So not sure that is the issue anymore.

Replace the oil pickup gasket. the camshaft variators work on oil pressure and I think you don't get enough

Have they explained how they know it's the timing belt rather than the crank or camshaft sensor(s) or a variable valve timing issue.
Hey wbanham, they advised that the error is stating it is a timing issue that they tried to erase but it keeps popping back on.If I remember correctly they said it was to do with the cambelt timing(the error that is) They said that it might be a bad job done previously, that they may have not used the correct cambelt locking tools for Alfa. I will call them tomorrow to get that info but also taking it to have a diagnostic to double check what they said is correct.

Post #6 is what you need to do.

These engines are notorious for bad oil pump seal. When this happens you will get low oil pressure warnings.

After thinking on it I bet it's either that or a bad camshaft variator (or both??). The latter can cause check engine light too and confuse the shop into thinking the timing is out.

Either way if you're still getting low oil pressure warnings try not to drive the car too much before repairs as it does inevitably result in premature wear which is very apparent after a teardown. Saw a post elsewhere on that not long ago - it looked like the engine had at least twice the amount of mileage it actually had. Bad oil pump seal and genuinely low oil pressure is much more common than faulty sensor.

PS. Doesn't necessarily mean that the shop is bad, but this tells me they don't know that much about TBi engines specifically. Did they at least check the oil pressure with external gauge?

By beeping do you mean the MIL engine light comes on?

You said the garage told you the timing was out based on an error code. Surely they would have told you if an oil pressure error code was also still being logged since the new oil pressure switch.

The low oil pressure light turns on and off. Will do it a number of times. This is additional to the mil light. But the mil light only came on a week after the remap.

When the garage was changing the oil pressure sensor they said it was probably the cause of the engine management light. When I picked the car up after the change of the sensor the engine management couldn't be reset and that is when they said the engine code said the code was saying it was the timing was out. But that was never something that was present from the start. It was only the the low oil pressure warning.

Cheers Wbanham. I have just got my car back from having a diagnostic as I wanted to check that they were giving me the right info.

The results say:

P0017-78 Camshaft/crankshaft assembly-alignment or adjustment incorrect.

B1039-64 vehicle dynamic switch plausibility failure

B1906-77 mix motor

Taking the car back to the mechanic to leave over night so they can check the oil pressure in the morning while the engine is cold. They carried out a test when it was warm and the results were fine.

Ask them to look at the things you guys have mentioned.

If DNA starts working after P0017-78 is fixed , you can probably ignore B1039-64.

B1906-77 is your right or left temp mixing flap. Motor may be dead. Easy enough to test
