Hi, today I noticed my Volvo 850 has an oil level sensor installed in the front of the oil pan but it's not connected to the harness, it's a 1993 T5 I think is one of the first t5s produced but I dont know exactly , can I make the oil level sensor work in any way or is missing the wiring needed for ...

Yesterday i replaced the ABS module and yes that was the issue now the car brakes much better but the manual says this: If system has been completely or partially drained of brake fluid, system must be pressure-bled. I didnt presure bleed because i dont have a presurre bleeder, i just did the typica...

so i went ahead and removed the flexi hoses, the first thing i did was to blow through them to see if they were collapsed well they were not, i asked a friend to push the pedal and even doing the maximum force no fluid was comming out the metal line without the hose atached, i disconected the line t...

i never changed the flexi-hoses, the pedal is hard, and about the check valve, it is on the brake booster i pulled it with the engine runing and it was sucking air correcly. Im going to buy some flexy hoses, maybe a metal ones and replace them, even if those are not colapsed is not a bad idea to rep...

Hello, since i got my 1993 850 t5, the braking performance was pretty low, i thought it was normal untill i drove my friends 1997 V70 LPT on this car the amount of force needed for the same braking power is like 1/3 compared to mine its has another brake circuit with different brake booster but stil...

Today I replaced the tcv, I installed a newer model (pierburg), the boost is no more spiking it keeps stable but I still see It a bit lowish, tomorrow will install a boost gauge and see how much it's really boosting.
How much psi should a t5 boost in normal conditions?

My cbv is holding vacuum perfectly I didn't pull it to inspect but it seems ok. Today I adjusted the wastegate to spec and I got a faster spool but now the boost is unstable between 3k and 4k rpm it's bouncing back and forth between half white lane a 3/4 during that range. Should I pull the cbv to i...

i cleaned the tps and the values are ok now they increase as you accelerate bettwen pin in the middle and the one on the side, but the boost issue is still present, nobody solved something like that?

i unpluged the tps and conected aligator pliers to the pin 1 and 3 then tested resistance
