Engine cut out problem – E34 518SEi
I was driving home from work last week when the engine on my E34 518 completely cut out while I was doing 40mph, there was no stuttering or spluttering, the engine just went completely dead. When I tried to indicate to warn other drivers that I was about to stop, I noticed that the indicators also no longer worked (although they did when the hazard switch is selected). A number of internal lights had also turned off – dash cluster lights were all off (besides the odometer LEDs), the stereo was still working and illuminated and the head lights were still on too. Additionally the power steering was not working. When I came to a complete stop I took out the ignition key, replaced it and the car started. While completing my journey home, the same problem occurred one more time.
The following day I popped the bonnet for a layman inspection, but could not see anything loose or out of the ordinary. So, I took the car to my local (usually very reliable) garage for inspection. Unfortunately, they could not seem to replicate the problem, though they did replace a cracked ‘vaccum tube’ and checked and cleaned the engine idle value. They also checked for fault codes, but reported that no codes were logged! They suggested re-testing the car to see if the vacuum tube was causing this issue. Unfortunately it was not and subsequently on driving the car today, I experienced the problem twice, and on one occasion I was able to dip the clutch and restart the engine while still moving.
Has anyone else had a similar problem? Any help would be much appreciated…
With regards to fuel, I filled up last week (full tank) and have about ¾ remaining.
