X5 Help - Tramlining and Pogo

[Mirinjawbro]

Hello all

have got an f15 X5 which annoyingly is tramlining quite bad. it seems to be getting worse unless its just been the roads i've been on lately

anyone had this and can guess what the most likely issue/s are?


on country back rounds it is very pogoey like the old M240I i had. once it passes a bump it takes a while to settle itself out. Sport mode does help on this though. is this normal?


thanks

Sounds like suspension alignment is out (tramlining), maybe exaggerated by the extremely heavy RFT and 20" (I am guessing) wheels, and suspension that is worn out, or a strut blown (pogoing).

Either way, visit to a garage is obliged

As above; it needs looking at and then tracking/alignment fettled

My F01 that came on 20s tramlined like crazy; tracking was spot on. Stupid 20" RFTs were the issue... Dropped to 18s for winters and 19s for summers (non RFTs) and it had zero issues after that

Yep, sounds exactly like blown rear shocks to me.
