- VS Berlina Series II
I have experienced a rapid failure of the drive on my VS Series II Berlina and hope someone here may offer some clues.
Currently I have no reverse, or even engagement of reverse but the fault has changed since the first sign of a problem just 800 metres beforehand.
Hopefully the symptoms may be enough to describe the situation.
Cruising on open road for an hour and slowed for another 70Km/H zone. Suddenly heard strange rumbling from what seemed like front right wheel area.
A Brrrrrrrr, of a second or two, then paused, possibly as i lifted my foot, and then a repeat brrrrrr . My initial thought was rumble strip but then plastic inner guard fouling.
I stopped and all seemed normal. Car idled normally etc. On take-off again the noise reappeared so I turned into a side road driving 300 metres to find a suitable area to stop and investigate. Noise may have changed to a screeching at times, like a bearing whine. (Alternator screech)
I then drove 300 metres back to park the car for the night. Screeching at times in lower gears as I crawled along.
During the retrieve I noticed engagement of reverse immediately brought on the noise. The car seemed ok at low rpm when Drive was selected. I then completely lost Reverse for a period. Drove onto the trailer normally, forward. Reverse had returned, at least it could be selected but although quiet at idle screeched when trying to take load/few rpm.
The car currently is home and awaiting work.
I can select and take load on all forward gear selections. Engine operation is normal, no abnormal lights and the diagnostic code is 12.
I changed ECU and the fault and code is unchanged.
At the moment the fault is now a failure for the vehicle to even see the reverse selection, it is like selecting a second Neutral.
Engagement of Forward gears is normal with about a 0.5 second delay on loading the engine. That said, I think it may have been hanging in the lower gears as I moved it to load onto the trailer.
No noise at the moment. Hasn't been since reversing, at low power, off the trailer. I lost Reverse completely (again) at the next engine start.
I obviously have a major transmission issue or an electrical problem.
Given the transmission was working very well until the first sign of a problem, the noise. I can't see it being a wear problem. Sudden failure, maybe, but the nature of the beast has been changing in the few minutes of abnormal operation.
The car has a history of electrical glitches most of which I have just lived with.
The headlights dimming was cured by fitting another section of fusebox. Dirty fuse contacts in that portion of the original box was the culprit.
Some electrical functions have not worked since I got the car 2 years and 40,000K ago.
High beam flash. ( Low and High selection/operation normal)
Others work at times.
Reverse lights. Movement of lever helped.
Security and central locking stopped working 6 months ago.
Hopefully I have provided enough detail for the sleuths here to offer some suggestions.
