Just acquired a 2000 166 3.0 V6 Sportronic and thought I'd chronicle my experience here if any other Alfa newbies are interested in a 166.

The car: Silver, manufactured year 2000, 3.0 V6 with sportronic gearbox. Light grey leather interior, DSP amp, 17" horseshoe rims with Michelin Pilot Sport 225/45/17 fitted. 182k km.

The car has had a lot of work done in the past year by the previous owner including timing belt, all four dampers changed to Bilsteins, all four brake discs and pads changed, front lower arms,, steering tie rods, engine top mount...

When I first tested it the airbag light was on, subsequently found to be loose connector under the passenger seat.

Handbrake/brake fluid light also came on during the test drive. Found to be defective brake fluid sensor. Dealer agreed to bear half the cost of replacing it.

Within 24hrs of picking up the car the battery light came on while driving, aircon started cutting out and battery low error messages appeared on the ICS. To cut a long story short, it needed a new alternator. The alternator specialist recommended uprating to 140ah which I agreed to. Now running fine except for one small issue.

Whenever I lift off the throttle suddenly and then try to reapply power, eg in traffic, there is a slight hesitation. This hesitation also appeared when braking and lifting off for a tight corner then reapplying power to go up a moderately steep slope. Is this normal or does something need looking at?

Another issue is tyre pressure. The official recommendation is for 2.7 bar all round, 270kpa/39psi. With the yellow Bilsteins and 225/45/17 Michelin Pilot Sports the ride is quite firm.

Should I try slightly lower pressures? Or look for a tyre with softer sidewalls?

The dampers make it a firm ride, I've stopped using sport rubber and gone for avon with the v tread(always to have eagle f1). The Avon are much much better on the road!

Does have car hesitae at around 4000rpm?

Do you mean the engine or the auto gearbox delay, if engine could be the maf or a leak in the rubber intake pipe, if gearbox try a ecu reset.

Performed simple throttle reset: insert key and turn to MAR, leave for 90secs. Do not crank the engine. Turn key back to off, do not remove key, wait 90 secs. After that start as normal.

The throttle was immediately more responsive, will have to try that slow 90deg turn and uphill climb to see if the car works better there.

New issue today, was taking an uphill right hander moderately fast and heard what sounded like the outside front tire rubbing against the wheel arch.

The car has, I believe, standard springs with yellow Bilstein dampers. Tires are 225/45/17 Pilot Sport 2s. The dampers were newly installed last year, so were the front lower arms, no info on the springs. Are my front springs knackered?

New issue: after motorway runs of abt 15 mins at 120-130kmh at ambient temps of 35deg C and 25deg C and then reducing speed when going off the motorway, there is a very noticeable whirring noise from the engine bay which varies with engine speed. Is this the radiator fan switching to high speed to keep the engine cool or is there a problem?

Thanks in advance.

Have been advised the noise from the engine bay is the aircon compressor which needs servicing, so it will go in tomorrow...

Aircon compressor was reconditioned, system fully serviced but the noise continues to make an occasional appearance.

Of course it refused to manifest when at the workshop, mechanic suggests to leave it until the noise is louder or becomes constant rather than intermittent and it becomes easier for them to track the source.

Tire pressures: have tried the 2.7 bar (39 psi) pressure as recommended for my 225/45/17s but when checking pressures after running on the motorway they were as high as 43psi. Tyre shop recommends 34/35 psi when cold since we have higher ambient and road temps here in Malaysia. What do you guys think?

Persistent smell of petrol in and outside the car after a drive, strongest in the boot. Diagnosed as a cracked fuel pump which has been replaced.

What next?

I had exact same issue and cause as that in my (much missed) 155 - which before it was rectified used to get referred to in pre-travel conversations as "Shall we go in your car or do you want me to take the 'Zippo'?" :D
