The standard answer to your question is air in brake fluid. I bet that careful bleeding of brake fluid and your problem is gone. With a car equipped with ABS, bleeding can be tricky. New rotors won't fix this problem. When your car idles and you press brake pedal hard, it reaches a limit and does no...

I'm sorry to hear about yout bad luck.

One option to look for damage due to wrong timing would be to use an endoscope (or a 'snake camera') to look inside the cylinders. If the valves have made contact with the pistons, I suppose you would see some marks on piston heads.

What I've encountered with my T5 2003 250 000 km this far: Radiator fan control: short circuit in power transistor (needed to replace the whole fan) Cabine fan: bearing issue Engine support issues: both underneath/above the engine Automatic transmission: was replaced in my car after 100 000 km Instr...

Hesitation has grown worse now. I still suspect a vacuum leak and I'm going to recheck for them again. Gotcha! I found a massive tear in the rubber hose just before intercooler intake by visual inspection. I did blow butane around the area when checking for leaks for the first time. Apparently, it ...

I'm sorry I've been a way for a while... I'm back to the problem again. "...Measurement showed that MAP sensor is fully functional...." Understood. How was that measurement performed? I used a vacuum pump to produce positive and negative pressure. The sensor was attached to a power supply....

I finally found the MAP connector wiring diagram (for Facet replacement sensor): http://img.findpart.org/images/820/820880.jpg Measurement showed that MAP sensor is fully functional. The strange thing is, that MAP reading in OBD scanner is still zero. Maybe it is a wiring problem from MAP to ECU. St...

That's right, P0127 is the only code I'm getting. IAT and MAP are in one 4-wire package. If you are measuring resistance through the MAP sensor and don't get any change in reading even though you you've run the pressure up and down with a vacuum pump, I'd be suspicious of that sensor. Well, I didn't...

Hello fellow volvoists, I've got a problem with hesitation and cannot figure out which one of the sensors in the topic is the culprit. I wouldn't like to just change sensors until a faulty one is found, perhaps one of you can help me to find the problem. I try to be comprehensive. Thanks in advance!...

To answer my own question: Detaching is not possible without doing too much damage. Actually, there is no connector at all. So removing the whole assembly is necessary in any case.

Hello fellow volvoists, I'd like to part the cooling fan control box from the rest of the fan assembly for inspection. I believe that the control box is not meant to be removable, but is there a way to detach it without breaking the connector? The assembly is still in place , which makes it complica...
