My friend bought -90 Synchro 1,6 TD = ($8000 USD) from Airiston Auto Oy . Short after (few days) he noticed oil pressure warning buzzer and led = starts to alarm on the road. He drove car back and = complains this. They said 'ok, the pressure sensor has = gone, we'll change it'. The car was under service = two days and both sensors, regulator and the dynamic pressure sensing pcb was changed. Then it suddenly is fixed. My friend asked if they = had loosen some wire to solve the problem (as for joke)... they said = 'Absolutely not..now it is ok'. And = everything seems to be ok..until..

About month later my friend changes = oil and filter and noticed that there is some wire loose from alternator and = wrapped to harness. He asked me if I knew what it was..and I knew (thanks to = the list and Bentely manual I own). We connect the wire and..here we are again..buzzer and led alarms.

Technical background: If this = wire from alternator is loose dynamic oil pressure sensor system does not know = motor is running above 2000 rpm and don't check the status of higher sensor while = lower pressure sensor is still active => everything seems to work fine.

My friend go back to the service and asks if they = have fixed the defect really. After long negotiations they admit fooling and = say that they know all time that the bearing surfaces of intermediate axle had = worn out and it has to be machined. This wearing causes loosing of oil pressure. They promise to fix it (this time other way) and give = him other car meanwhile.

How many = cars have been sold from this shop and others all round the world fixed lile = this? Is this common method (at VW) to fix it? Comments = welcome!
