Hello,
a month ago I have replaced Vanos seals in my E39 525i (M54B25) ’00 with 190k km, everything like in Beisan solutions. The problem was power decrease at scope 1000-3000 rpm, poor accelerating. After replacing seals everything back to normality, like in new BMW
Unfortunately, after 2500km the problem was return. Decrease power, poor acceleration (IV gear 80-120km/h in 13s! – standard ~8,5s) etc. My car is behaving like before Vanos seals replacing!
GT1 and INPA shows no engines errors.
Except Vanos seals I have replaced:
- vanos gasket
- 2 x vanos oil hose/pipe washer
- 15 x valve cover bolt grom met
- camshaft position sensor
- 6x ignition plugs NGK BKR6EQUP
- battery
Any suggestions?
P.S. Sorry for my English, it's not my mother tongue.
